BUSINESS REVIEW

Financial overview

The group has delivered a good set of financial results for the six monthsended 30 September 2011. Revenue was up by £30 million to £793 million,principally as a result of the impact of the regulated price increase for2011/12 of 4.5% nominal (0.2% real price decrease plus 4.7% RPI inflation).However, reflecting continued progress on the capital investment programme,infrastructure renewals expenditure was up £18 million. This expenditure,alongside increases in depreciation and property rates and other inflationarycost pressures, resulted in underlying operating profit decreasing marginallyby 1% to £324 million. United Utilities (UU) remains on track to deliver itsregulatory outperformance targets.

Regulatory capital investment in the half year, including £66 million of infrastructure renewals expenditure, was £275 million. This represents good progress in the early part of the 2010-15 period, as management has sought to deliver a smoother investment profile to support efficient delivery of outputs and reduce risk.

Underlying profit before taxation was lower by 5%, at £185 million. This reflected a slightly lower underlying operating profit and a small increase in the underlying net finance expense, mainly relating to indexation of the principal in respect of the group's index-linked debt.

Underlying profit after taxation was marginally lower than thecorresponding period last year, reflecting the movement in underlying netfinance expense. Reported profit after taxation benefited from a £50 milliondeferred taxation credit, which follows the UK government's changes to reducethe mainstream corporation taxation rate. A similar credit of £47 million wasrecognised in the first half of last year.

UU has a robust capital structure and gearing (measured as group net debt to regulatory capital value) as at 30 September 2011 was 60% and comfortably within Ofwat's assumed range of 55% to 65%, supporting a solid investment grade credit rating. United Utilities Water PLC (UUW) has a long-term credit rating of A3 from Moody's Investors Service with a stable outlook.

Following the agreement of a further £200 million index-linked loanfacility with the European Investment Bank (EIB) earlier this month, the groupnow benefits from headroom to cover its projected financing needs into 2014.This provides good flexibility in terms of when and how further debt financeis raised to help fund the regulated capital expenditure programme. Reflectingthis robust financing position, UU accelerated approximately £100 million ofpreviously agreed pension deficit payments in September 2011, providing ahigher return for the group than could have been achieved through short- termdeposits.

UU has secured around £300 million of financing outperformance over the 2010-15 period (based on an average RPI inflation rate of 2.5% per annum), is targeting total operating expenditure outperformance of at least £50 million and expects broadly to meet its capital expenditure allowance.

In line with its policy, the board has declared an interim dividend of 10.67 pence per ordinary share, an increase of 6.7% compared with the interim dividend relating to 2010/11. The intention is to continue with this policy of targeting dividend growth of RPI+2% per annum through to 2015.

OPERATIONAL PERFORMANCE

UU aims to deliver long-term shareholder value by providing:

- The best service to customers

- At the lowest sustainable cost

- In a responsible manner

Operational performance is a top priority for UU and the company aims to deliver improvements in this area and outperform its regulatory contract. The business recently revised its range of key performance indicators (KPIs) to enhance the visibility of its performance and help drive improvements.

Supporting this drive to improve operational performance, a revisedmanagement structure has been put in place with a strong focus onaccountability and delivery. The company has moved, from its previousfunctional structure, to an organisational structure that is aligned to thedelivery of efficient processes. Managers are now responsible for end to enddelivery of capital projects and operational performance within theirrespective regions, providing a more integrated approach. A `whole company'scorecard has also been introduced and short-term incentives are now moredirectly aligned with operational performance. Long-term incentives arealigned with shareholders' and customers' interests, being based 50% on totalshareholder return and 50% on regulatory outperformance.

Best service to customers

Actions:

Customer initiatives - UU recently established a customerexperience programme to help deliver improved customer service. The businessnow offers additional contact options for customers, such as an online accountmanagement facility, to provide more choices as to when and how they cancontact the company. Staff availability has recently been extended, coupledwith a simplified automated telephone routing system and an online call backfacility. A priority is to improve customer data management to ensure thisprovides a single view of the customer to help improve the efficiency andquality of service. Supporting this customer experience programme, thebusiness has increased staff training, better aligned staff incentivemechanisms, put new service level arrangements in place, substantially reducedwork queues and backlogs, and proactively contacts customers to keep theminformed of progress in respect of their enquiries. The company is nowfocusing on identifying potential customer queries in advance, through moreproactive exception billing reporting and contacting the customer before thebill is sent to discuss the matter. Operationally, the business is targetingsame day completion of jobs to improve the customer experience and reduce theneed for unnecessary calls.These initiatives are improving customer service and UU has seen a20% reduction in the total number of complaints in the first half of 2011/12compared with the second half of 2010/11, alongside a further substantialreduction in contacts with and customer complaints assessed by the ConsumerCouncil for Water (CCW). The company has also improved its performance onOfwat's service incentive mechanism (SIM), with a 42% improvement on thequantitative measure in the first half of 2011/12, compared with the firsthalf of 2010/11, and has moved up two places on the qualitative measure.Although this still places UU in the fourth quartile, it does represent goodprogress. Improving customer service further remains a significant area ofcontinued management focus.

Safe, clean drinking water - UU has an action plan to maintain safe, clean drinking water through improving the robustness of its water treatment processes, refurbishing service reservoir assets, ongoing mains cleaning and optimising water treatment to reduce discoloured water events. UU continues to supply a high quality of drinking water, with a mean zonal compliance water quality performance of 99.96%.

Water supply and demand balance - To help ensure a continuous watersupply to its customers, UU's action plan includes innovation and investmentin remote monitoring to better manage and control the company's water supplysystem. UU also has investment projects to optimise water pressures andimprove network resilience. In addition, the company is improving its responseto burst mains to help keep the water flowing, supported by `wet' repairs towater mains where the supply remains on through the repair process. Thecompany has completed the West East Link, a significant capital projectdesigned to improve further the water supply and demand balance in its regionand enhance network resilience to climate change.Wastewater - The company has a range of actions to help support theserviceability of its wastewater assets. To help reduce sewer flooding, theseactions include incident based targeting to focus on areas more likely toexperience flooding, effective intervention in cleaning and rehabilitation orrefurbishment of sewers and advising customers about items not suitable forsewer disposal. The plan also includes an improved approach to risk assessmentto identify and reduce the risk profile of the company's wastewater treatmentworks.Private sewers - The ownership of and responsibility for privatesewers was transferred to the English and Welsh water and sewerage companiesfrom 1 October 2011, providing additional benefits for customers and theopportunity for additional growth in the regulatory capital value. UU had beenpreparing for this for some time to help ensure a smooth transfer and thelevel of customer contacts and the increase in work volumes, thus far, hasbeen broadly in line with expectations. UU outlined its 2011-15 operating andcapital expenditure cost estimates in relation to private sewers in its2010/11 full year results published on 26 May 2011, which were total operatingexpenditure of £55 million and total capital expenditure of £125 million (ofwhich £90 million relates to infrastructure renewals expenditure). There is nochange to the initial cost estimates at this early stage, but UU will continueto assess and review these cost estimates in light of the levels of workloadand activity experienced.Key performance indicators:- Serviceability - Long-term stewardship of assets is critical andOfwat measures this through its serviceability assessment (Ofwat definesserviceability as the capability of a system of assets to deliver a referencelevel of service to customers and to the environment now and in the future).Three asset classes (water infrastructure, water non-infrastructure andwastewater non-infrastructure) continue to be rated "stable". UU has beenassessed by the regulator as "marginal" in respect of wastewaterinfrastructure and the company has an action plan in place to return thisasset class back to a "stable" rating. The aim is to hold a "stable" ratingfor all four asset classes, which is aligned with Ofwat's target.- Service incentive mechanism (SIM) - Ofwat has recently introducedthis new measure, which replaces the overall performance assessment (OPA)measure. UU improved its quantitative score for 2010/11 by 44%, compared withthe indicative position for 2009/10. Further improvements have been achievedin the first half of 2011/12, with a score for the half year of 181 points.This represents a 42% improvement on the first half of 2010/11 and 19% on thesecond half of that year. On the qualitative measure, UU has improved itsquarter two score for 2011/12 to 3.99 points, from 3.79 points for the 2010/11financial year, which has moved the company up two places into nineteenthposition (out of 21 water companies). UU is nineth out of the ten water andsewerage companies. Although UU remains in the fourth quartile, this earlyprogress is encouraging. The aim is to move to the first quartile in themedium-term.Lowest sustainable costActions:Staff and pensions - The group placed its pension provision on amore sustainable footing in 2010 and has subsequently taken additional stepsto de-risk the pension scheme further. An inflation funding mechanism has beenintroduced, which has facilitated a move to a lower risk investment strategywith the proportion of pension assets invested in equities now reduced to 20%.The contributions made by UU are flexed in line with inflation, with a rollingfive-year smoothing arrangement to help mitigate fluctuations in RPI. Overall,the de-risking measures taken should result in less volatility in pensionfunding levels. More details on the inflation funding mechanism are providedin the pensions section.Asset optimisation - The company's asset optimisation programme isprogressing well, providing the benefits of increased and more effective useof operational site management to optimise power and chemical use and thedevelopment of more combined heat and power (CHP) assets to improve energyefficiency. The implementation phase is underway at over half of the 30 sitescovered by the programme and a large number of schemes came on line in summer2011, with further projects being scoped. The optimisation programme istargeting approximately £9 million of annual savings by 2013.

Proactive approach - The business is introducing a more proactive approach to asset and network management, with the aim of improving its modelling and forecasting to enable it to address more asset and network problems before they occur, thereby reducing the level of reactive work and improving efficiency.

Power hedging - UU has increased its power hedging and has now substantially locked in its power requirements through to 2014/15, securing outperformance. Power unit costs for 2011/12 are approximately 20% lower compared with 2009/10. Although power unit costs beyond 2011/12 have been secured at higher levels than those for 2011/12, this still delivers additional outperformance versus the regulatory contract.

Debt collection - The business is adopting a more proactiveapproach to debt collection. It has a detailed action plan in place, whichincludes enhancing systems to improve customer segmentation analysis and toobtain better data on customers who have changed address, coupled with a moreproactive debt follow up strategy. To support this, a proportion of its debtcollection function which was previously off-shored was brought back in-housein the last financial year and this is delivering benefits. In addition, thecompany is planning to use more local authority collection agreements. Baddebts as a proportion of regulated revenue improved from 2.5% in 2009/10 to2.1% in 2010/11 and this improvement has been sustained so far in 2011/12,despite the challenging economic environment.

Lean principles - Supporting the company's efficiency drive is its lean principles approach to doing business. Systems and processes continue to be streamlined and the business is rationalising its infrastructure and has in-sourced its IT provision to provide greater control of its IT assets and applications.

Leakage management - The performance of the business in meeting itsregulatory leakage target for 2010/11 was exemplary, given the extreme winterweather. UU was one of only four water and sewerage companies to meet itsregulatory leakage target last year. This reflected strong year roundoperational focus on leakage, an approach which the company has continued in2011/12 and this has created a buffer to help compensate for the inevitableadverse impact of winter weather. The company has also launched its `GetWinter Wise' campaign, which provides advice to customers on how to reduce therisk of frozen and burst pipes as a result of cold weather.Capital delivery - The business has utilised previous experience toimprove the terms and conditions of its supplier contracts and has a robustcommercial capital delivery framework in place for the 2010-15 period.Contractor performance is aligned with the company's business plan throughappropriate incentive arrangements. In addition, the business has introduced amore disciplined approach to spend and outputs through a Time: Cost: Qualityindex (TCQi). This enhances the capital investment governance process andprovides a sharper focus on the delivery of commitments, with a direct link tothe executive remuneration scheme. The TCQi performance score has improvedfrom around 50% last year to over 70% currently and the company's long-termgoal is to achieve over 90%. UU remains on track to deliver up to £700 millionof capital investment in 2011/12. Good progress in the delivery of outputs hasbeen achieved in the early part of the new regulatory period, reflecting asmoother and more efficient investment profile than that experienced in the2005-10 period.Sludge processing - A new £100 million sludge processing centre isbeing developed at the company's Davyhulme wastewater treatment works inManchester. Sludge will arrive from seven feeder treatment works and will beprocessed using advanced thermal hydrolysis technology. The new facility willprovide a range of benefits including energy self-sufficiency for the wholesite, greater sludge disposal flexibility, with a wider choice of landdisposal due to the advanced stage of the treated product, and improved sludgecondition to enhance the efficiency of incineration. There will also be theoption to pump the treated sludge to UU's Shell Green sludge processing centrein Widnes. Early progress has been good and the project is scheduled to becompleted in early 2013.

Key performance indicators:

* Relative efficiency - UU has made improvements on both the waterservice and the wastewater service in 2010/11 (based on UU's internalassessment of Ofwat's econometric models). The company has improved itsrelative efficiency banding to band A for water and is now in the firstquartile for this service in second position. The business has also moved upone place for wastewater into nineth position and remains in band C on thisservice. Overall, this places UU in a mid-ranking position and the aim is tobe first quartile on both services in the medium-term.

* Leakage - UU met its economic level of leakage rolling target for the fifth consecutive year in 2010/11, despite extreme winter weather conditions. The aim is to meet its regulatory leakage target, as set by Ofwat, each year.

Responsible mannerActions:Corporate responsibility - Sustainability is fundamental to themanner in which UU undertakes its business and the group has for many yearsincluded corporate responsibility (CR) factors as a strategic consideration inits decision making. This has contributed to UU retaining the highest platinumplus ranking in Business in the Community's (BITC) CR index, alongside onlyfive other FTSE 100 companies, as well as again being rated `World Class' inthe Dow Jones Sustainability Index. UU's CR policy sets out its commitment toenvironmental, social and economic improvements and this is communicated in away that enables all employees to recognise how their roles andresponsibilities contribute to maintaining and improving sustainabilityperformance.

Sustainable catchment management programme - UU owns approximately 57,000 hectares of land in the North West which it holds to protect the quality of water entering its reservoirs. The company has developed a sustainable catchment management programme which will help to enhance biodiversity and protect and improve water quality.

Renewable energy - UU has a detailed carbon and renewable energy plan, which both contributes to sustainability and reduces costs. In 2010/11 the company generated 111 GWh of renewable electricity, principally from sludge processing. This represents approximately 14% of the group's total electricity consumption.

Environmental performance - This is a high priority for the companyand UU has more than halved the number of major pollution incidents over thelast few years. Wastewater treatment works compliance remains high at over98%, a slight improvement compared with the previous year. UU is working moreclosely with the Environment Agency (EA), through its agreed protocol, to helpminimise the occurrence and environmental impact of pollution incidents. Thisincludes the sharing of resources, knowledge and expertise. The company isalso enhancing its telemetry and flow monitoring equipment to provide earlyidentification of incidents to enable prompt action to be taken to minimisethe potential impact. Recognising that environmental performance iswide-ranging, the company is measuring itself against an EA composite measureas detailed in the key performance indicators below.

Key performance indicators:

* Environmental performance - The EA computes a composite measurewhich incorporates a broad range of areas including pollution. UU improved toa mid-ranking position for 2009/10 improving from its position in 2008/09,when it was ranked tenth out of ten water and sewerage companies. The companyhas reduced further the number of major pollution incidents and this hascontributed to an improved performance score for 2010/11 and UU retains amid-ranking position. UU aims to move from this average relative position tothe first quartile in the medium-term.

* Corporate responsibility - UU has a strong focus on corporate responsibility and is the only UK water company to have a `World Class' rating as measured by the Dow Jones Sustainability Index. The group aims to retain this `World Class' rating each year.

Outperformance of regulatory contract

* Financing outperformance - UU has secured around £300 million offinancing outperformance over the 2010-15 period, based on an average RPIinflation rate of 2.5% per annum. Should average RPI inflation outturn at 3.5%p.a. across the five-year period, this would increase financing outperformanceto around £400 million, net of the impact of the pensions inflation fundingmechanism. The aim is to raise future financing, as required, at interestrates that will deliver further outperformance when compared with Ofwat'sallowed cost of debt of 3.6% real. UU agreed a £200 million index-linked loanwith the European Investment Bank (EIB), drawn down between March and May2011, at an average real interest rate of 1.2%, which secures financingoutperformance of around £20 million through to 2015. Subsequently, a further£200 million index-linked loan facility was agreed with the EIB earlier thismonth and, although pricing is still to be finalised, it is expected that thiswill deliver additional outperformance.* Operating expenditure outperformance - The business is targetingtotal operating expenditure outperformance over the 2010-15 period of at least£50 million, or approximately 2%, compared with the regulatory allowance. Thisis in addition to the base operating expenditure efficiency targets set byOfwat, which equate to a total of approximately £150 million over the fiveyears. UU made good progress in 2010/11 and achieved operating expenditureoutperformance of around £10 million and is targeting a further £10 million ofoutperformance for 2011/12.

* Capital expenditure outperformance - UU is delivering significant efficiencies in the area of capital expenditure and expects broadly to meet Ofwat's revised allowance after adjusting, through the regulatory methodology, for the impact of lower construction output prices.

Political and regulatory developments

UU is actively involved in political and regulatory developments that relate to the UK water sector and has a proactive programme to regularly engage with the key parties. The company has emphasised that benchmark competition has already delivered significant environmental and customer service benefits and can be improved further by adjusting the incentive regime. UU has sought to focus the debate onto areas such as how the sector can help address climate change, sustainability, affordability and water efficiency.

* Climate change and sustainability - Two key challenges facing thewater sector are climate change and sustainability, both of which are expectedto feature in the forthcoming Water White Paper. In addressing these twinchallenges, UU supports exploring the role of water trading in ensuring thatwater is allocated where it is valued most and that innovation and investmentto enable reductions in abstraction or provide additional storage areencouraged. It would be beneficial to establish appropriate levels of securityof water supply and resilience of assets and networks in the event of majoroutages.* Affordability - Ofwat estimates that the average annual householdbill is around £100 lower than it would have otherwise been without thesignificant improvements in efficiency since privatisation. Despite this, UUrecognises the challenge of keeping bills affordable for all customers andbelieves that maintaining investor confidence is critical for the industry tocontinue to raise finance and invest efficiently. Adopting a proportionateapproach to implementing new environmental regulation would also help keepbills affordable. In addition, UU believes that any expansion of retailcompetition should be consistent with the government's position onaffordability.* Water efficiency - UU believes that water companies are in aunique position to help facilitate the use of scarce water resources bycustomers. Recent measures adopted by the company include distributing showerregulators and devices to reduce flush volumes in toilets and rolling outeducation programmes. UU believes that more can be done to promote waterefficiency and the company supports the refinement of the regulatory frameworkto provide companies with incentives to encourage the wise use of water. UUalso supports the promotion of education and innovation in the area of waterefficiency.OutlookUU has a robust capital structure and a sustainable dividend policy, targeting 2% per annum growth above the rate of RPI inflation throughto at least 2015. The company is focused on delivering further operational andcustomer service improvements and is making good progress. The action plansbeing implemented are delivering efficiencies and UU remains on track to meetits regulatory outperformance targets, with substantial financingoutperformance already secured. In the area of regulatory and politicaldevelopments, UU will continue to work with all key parties to help achievethe optimal outcome for all its stakeholders. The group expects to deliver agood underlying financial performance over the remainder of 2011/12.

FINANCIAL PERFORMANCE

Revenue

UU has delivered a good set of financial results for the six months ended 30September 2011. Revenue increased by £30 million to £793 million, principallyreflecting a 4.5% nominal (0.2% real price decrease plus 4.7% RPI inflation)regulated price increase.Operating profit

Underlying operating profit decreased slightly by 1% to £324 million, primarily as a consequence of the increase in revenue being offset by increases in infrastructure renewals expenditure, depreciation and property rates, alongside other inflationary cost pressures. Reported operating profit rose by 4% to £323 million, as the first half of last year was impacted by one-off restructuring costs of approximately £16 million which reduced operating profit in the comparative prior period.

Investment income and finance expense

Investment income and finance expense of £198 million was £9 million higherthan the first half of 2010/11, principally due to higher inflationary uplifton our index-linked debt during the period. The indexation of the principal onindex-linked debt amounted to a net charge in the income statement of £57million, compared with a net charge of £50 million in the first half of lastyear. This reflected a small increase relating to the £200 millionindex-linked loan facility with the EIB, to help fund the regulated capitalinvestment programme, which was drawn down between March and May 2011 at anaverage real interest rate of 1.2%, the lowest rate the company has achievedto date, and marginally higher RPI inflation in respect of the group'sindex-linked debt with an eight month lag. The indexation charge does notrepresent a cash flow during the half year and is more than matched by aninflationary uplift to the regulatory capital value. The group hadapproximately £2.4 billion of index-linked debt as at 30 September 2011.Investment income and finance expense included £56 million of net fair valuelosses on debt and derivative instruments, compared with £53 million of netfair value losses in the first half of 2010/11. The £56 million fair valueloss in the period is largely due to losses on the regulatory swap portfolioresulting from a significant decrease in sterling interest rates during theperiod. The group uses these swaps to effectively fix interest rates on asubstantial proportion of its debt to better match the fixed financing cashflows allowed by the regulator at each price review. The group has continuedto benefit from fixing the majority of its remaining debt for the 2010-15financial period, providing a net effective nominal interest rate ofapproximately 5%. Partially offsetting these losses, there has been a net fairvalue gain during the period due to widening credit spreads in the market,affecting the fair value of our fair value option debt and derivative assets.

The underlying net finance expense of £139 million was £7 million higher than the first six months of last year, principally due to higher inflationary uplift on our index-linked debt during the period. The group's average annualised underlying interest rate was broadly flat at 5.8%.

Profit before taxation

Underlying profit before taxation was £185 million, 5% lower than the firsthalf of last year, principally reflecting an increase in infrastructurerenewals expenditure in line with the planned investment profile, a smallincrease in the underlying net finance expense and a higher depreciationcharge as a result of growth in the commissioned asset base, which broadlyoffset the allowed regulated price increase. This underlying measure adjustsfor the impact of one-off items, principally from restructuring andreorganisation within the business, and fair value movements in respect ofdebt and derivative instruments. Reported profit before taxation increasedmarginally by 2% to £124 million.

Taxation

The current taxation charge was £34 million in the half year and the current taxation effective rate was 27%, compared with 25% in the corresponding period last year.

The group has recognised a deferred taxation credit of £50 millionin first half of 2011/12 which primarily relates to the change substantivelyenacted by the UK government to reduce the mainstream rate of corporationtaxation from 26% to 25% from 1 April 2012. This compares with a net deferredtaxation credit of £41 million in the first half of last year, which includeda £47 million credit following the change enacted on 27 July 2010 to reducethe mainstream rate of corporation taxation from 28% to 27% from 1 April 2011.An overall taxation credit of £16 million has been recognised forthe six months ended 30 September 2011. Excluding the impact of the reductionin the corporation taxation rate, the total taxation charge would be £33million or 27% compared with a £36 million charge or 30% in the first half oflast year. The reduction is principally due to the decrease in the mainstreamrate of corporation tax from 28% to 26%.

The taxation benefit of £18 million relating to pension contributions for deficit funding has been recorded in the statement of comprehensive income, rather than the income statement, as the actuarial movements giving rise to the deficit were previously recorded there.

The group made cash taxation payments during the half year of £29 million. In the first half of the previous year, the group's net taxation payment was £27 million.

Profit after taxation

Reported profit after taxation from continuing operations was £141million compared with £133 million in the corresponding period last year.Underlying profit after taxation was £136 million. This is based on theunderlying profit before taxation figure less an underlying taxation charge of£49 million, which includes an adjustment for the deferred taxation credit inrelation to the change in the mainstream rate of corporation taxation.

Earnings per share

Basic earnings per share increased from 19.5 pence to 20.7 pence,principally reflecting the aforementioned taxation credits and an increase inprofit before taxation in the current period. Underlying earnings per sharereduced slightly from 20.4 pence to 19.9 pence. This underlying measure isderived from underlying profit before taxation less underlying taxation. Thisincludes the adjustments for the deferred taxation credits in both the firsthalf of 2011/12 and 2010/11, associated with the reduction in the corporationtaxation rate.Dividend per shareThe board has declared an interim dividend of 10.67 pence perordinary share in respect of the six months ended 30 September 2011. This isan increase of 6.7%, compared with the interim dividend relating to theprevious year, in line with group's dividend policy of targeting a real growthrate of RPI+2% per annum through to at least 2015. The inflationary increaseof 4.7% is based on the RPI element included within the allowed regulatedprice increase for the 2011/12 financial year (i.e. the movement in RPIbetween November 2009 and November 2010).

The interim dividend is expected to be paid on 1 February 2012 to shareholders on the register at the close of business on 16 December 2011. The ex-dividend date is 14 December 2011.

Cash flow

Net cash generated from continuing operating activities for the sixmonths ended 30 September 2011 was £218 million, compared with £331 million inthe first half of last year. This is predominantly due to the acceleratedpension deficit repair payment. The group's net capital expenditure was £224million, principally in the regulated water and wastewater investmentprogrammes. This excludes infrastructure renewals expenditure which is treatedas an operating cost under International Financial Reporting Standards.

Net debt including derivatives at 30 September 2011 was £5,010 million, compared with £4,778 million at 31 March 2011. This expected increase reflects expenditure on the regulatory capital investment programmes and payments of dividends, interest and taxation, alongside the accelerated pension deficit repair payment, partly offset by operating cash flows.

Debt financing and interest rate management

Gearing (measured as group net debt divided by UUW's regulatorycapital value) marginally increased to 60% at 30 September 2011, compared with59% at 31 March 2011, and remains comfortably within Ofwat's 55% to 65%assumed gearing range. This reflects indexation of the principal of thegroup's index-linked debt and the accelerated pension deficit repair payment,with growth in the regulatory capital value resulting in just a slightincrease in gearing. The group now has a small pensions surplus of £28million, on an accounting basis, compared with a deficit of £195 million at 31March 2011. Taking account of this small surplus, and treating it as cash,gearing remains at 60%.

At the half year end, United Utilities Water PLC had long-term credit ratings of A3/BBB+ and United Utilities PLC had long-term credit ratings of Baa1/BBB- from Moody's Investors Service and Standard & Poor's Ratings Services respectively. The split rating reflects differing methodologies used by the credit rating agencies.

Cash and short-term deposits at 30 September 2011 amounted to £325million. Between March and May 2011 UUW drew down a £200 million index-linkedloan facility with the EIB. The group also renewed £100 million of bankfacilities in the first half of 2011/12. In addition, in November 2011, UUWagreed a further £200 million index-linked loan facility with the EIB. UU nowhas headroom to cover its projected financing needs into 2014.The group has access to the international debt capital marketsthrough its €7 billion euro medium-term note programme which provides for theperiodic issuance by United Utilities PLC and United Utilities Water PLC ofdebt instruments on terms and conditions determined at the time theinstruments are issued. The programme does not represent a funding commitment,with funding dependent on the successful issue of the debt securities.

Long-term borrowings are structured or hedged to match assets and earnings, which are largely in sterling, indexed to UK retail price inflation and subject to regulatory price reviews every five years.

Very long-term sterling inflation index-linked debt is the group's preferred form of funding as this provides a natural hedge to assets and earnings. At 30 September 2011, approximately 48% of the group's net debt was in index-linked form, representing around 29% of UUW's regulatory capital value, with an average real interest rate of 1.8%. The long-term nature of this funding also provides a good match to the company's long-life infrastructure assets and is a key contributor to the group's average term debt maturity profile which is in excess of 25 years.

Where nominal debt is raised in a currency other than sterlingand/or with a fixed interest rate, to manage exposure to long-term interestrates, the debt is generally swapped to create a floating rate sterlingliability for the term of the liability. To manage exposure to medium-terminterest rates, the group fixed interest costs for a substantial proportion ofthe group's debt for the duration of the 2010-15 regulatory period at aroundthe time of the price review.Following the 2009 price review, the group has assessed itsinterest rate hedging policy with a view to further reducing regulatory risk.To help address the uncertainty as to how Ofwat may approach the setting ofinterest rate costs at the next price review in 2014, UU has revised itsinterest rate management strategy and has now extended its fixed interest ratehedge out to a ten year maturity on a reducing balance basis. The intention isto extend the interest rate hedge each year to eventually achieve a ten yearrolling average interest rate on the group's nominal debt. UU believes thatthis revised interest rate hedging policy, which provides for a longer fixingof interest rates, will put the company in a good position to respond towhatever approach Ofwat adopts to the industry cost of debt in future.

Liquidity

Short-term liquidity requirements are met from the group's normal operating cash flow and its short-term bank deposits. The group has a €2 billion euro-commercial paper programme and further liquidity is provided by committed but undrawn credit facilities.

In line with the board's treasury policy, UU aims to maintain a healthyheadroom position. Available headroom at 30 September 2011 was £509 millionbased on cash, short-term deposits and medium-term committed bank facilities,net of short-term debt. This headroom is sufficient to cover the group'sprojected financing needs into 2014.UU believes that it operates a prudent approach to managing bankingcounterparty risk. Counterparty risk, in relation to both cash deposits andderivatives, is controlled through the use of counterparty credit limits. UU'scash is held in the form of short-term (generally no longer than three months)money market deposits with either prime commercial banks or with triple Arated money market funds.

UU operates a bilateral, rather than a syndicated, approach to its core relationship banking facilities. This approach spreads maturities more evenly over a longer time period, thereby reducing refinancing risk and providing the benefit of several renewal points rather than a large single refinancing requirement.

Pensions

As at 30 September 2011, the group had a net retirement benefit, orpension, surplus of £28 million, compared with a net pension deficit of £195million at 31 March 2011. This £223 million positive movement principallyreflects payment of the £100 million accelerated deficit repair contribution,investment returns exceeding expectations as a result of the effect of fallinginterest rates on the interest rate hedge put in place, and payments under theinflation funding mechanism. From an accounting perspective, IAS 19 treats theinflation funding mechanism as a schedule of contributions rather than apension scheme asset. This means that the liabilities position can change toreflect a change in market expectations of long-term inflation, without acommensurate movement in assets. The change in inflation has decreased thepresent value of the liabilities during the six months to 30 September 2011.This accounting treatment means that there is likely to be a degree ofvolatility in future pension valuations.

The group has sought to adopt a more sustainable approach to the delivery of pension provision and in the second half of 2009/10 amended the terms of its defined benefit pension schemes, the details of which were included in the 2010 annual report and financial statements. UU has also reduced its future pension obligations as a result of the sale of non-regulated activities.

The group stated previously that it would continue to evaluate itspensions investment strategy to de-risk further its pension provision and hasintroduced an inflation funding mechanism, which facilitates a move to a lowerrisk investment strategy. UU has agreed with the trustee of its main pensionscheme to use a lower investment return assumption and a fixed inflationassumption of 2.75% in carrying out a valuation of the scheme. In periods wheninflation is higher than 2.75%, UU will make additional contributions(smoothed over a five year period to help mitigate RPI fluctuations). Thecompany is comfortable in making these additional contributions, as itsregulatory capital value is linked to RPI inflation and therefore thisprovides a natural hedge against this risk. The inflation funding mechanismhas allowed UU to reduce the allocation of its pension assets to 20% inequities, from 34% at 31 March 2011. The group has also increased its interestrate hedge to around 65% of pension scheme liabilities. Overall, the mechanismprovides for less volatility in pension scheme funding levels. Although anyadditional payments under this mechanism would reduce financingoutperformance, there would be a positive benefit to the pensions surplus ordeficit position.

Further detail is provided in note 9 ("Retirement benefit surplus/(obligations)") of these condensed consolidated financial statements.

Going concern

The directors have reviewed the financial resources available to the group and have concluded that the group is a going concern. This conclusion is based upon, amongst other matters, a review of the group's financial projections together with a review of the cash and committed borrowing facilities available to the group.

Underlying profit

In considering the underlying results for the period, the directors have excluded fair value movements on debt and derivative instruments and one-off items. Reported operating profit and profit before taxation from continuing operations are reconciled to underlying operating profit, underlying profit before taxation and underlying profit after taxation (non-GAAP measures) as follows:

PRINCIPAL RISKS AND UNCERTAINTIES

The group maintains an internal control framework that assesses,throughout the year, the nature and magnitude of internal and external risksto the achievement of business goals. Managers are required to employ bothproactive and reactive mitigation measures in a prioritised manner to reduceexposures and ensure ongoing resilience should a risk materialise. Theexecutive management team regularly reviews significant risks so that theboard can determine the nature and extent of those risks it is willing to takein achieving its strategic objectives. The audit committee regularly reviewsthe framework's effectiveness and the group's compliance with it.The group's anticipated principal risks and uncertainties over thesecond half of the financial year and beyond remain as stated in its 2011Annual Report and Financial Statements. The principal risks and uncertaintiesare set out in full on pages 18-22 of the 2011 Annual Report and FinancialStatements, namely (a) government market reform agenda; (b) capital investmentprogrammes; (c) service incentive mechanism; (d) serviceability assessment;(e) the adoption of private sewers; (f) pension scheme obligations; (g)failure to comply with applicable law or regulations; (h) events, serviceinterruptions, systems failures, water shortages or contamination of watersupplies; and (i) material litigation (excluding the NOSS Consortiumarbitration in Thailand, which was settled in June 2011 within existingprovisions).

There has been no change to the nature of related party transactions in the first six months of the financial year which has materially affected the financial position or performance of UU.

1. Basis of preparation and accounting policies

The condensed consolidated financial statements for the six monthsended 30 September 2011 have been prepared in accordance with the Disclosureand Transparency Rules of the Financial Services Authority and InternationalAccounting Standard 34 `Interim Financial Reporting' (IAS 34).

The accounting policies, presentation and methods of computation are consistent with those set out in the audited consolidated financial statements of United Utilities Group PLC for the year ended 31 March 2011, which are prepared in accordance with International Financial Reporting Standards (IFRSs) as adopted by the European Union (EU).

The adoption of the following amendments to standards that are mandatory for the period commencing 1 April 2011, has not had a material impact on the group's financial statements.

'Improvements to IFRSs (2010)'

This is a collection of amendments to 7 standards as part of the International Accounting Standards Board's (IASB) programme of annual improvements. The improvements were issued in May 2010, are effective for periods commencing on or after 1 July 2010 or 1 January 2011 and were endorsed by the EU on 18 February 2011.

The group has updated the valuation of its defined benefit pension schemes in the half yearly financial statements due to continued volatility in the financial markets.

The condensed consolidated financial statements do not include all of the information and disclosures required for full annual financial statements, do not comprise statutory accounts within the meaning of section 434 of the Companies Act 2006 and should be read in conjunction with the group's annual report and financial statements for the year ended 31 March 2011.

The comparative figures for the year ended 31 March 2011 do notcomprise the group's statutory accounts for that financial year. Thoseaccounts have been reported upon by the group's previous auditor and deliveredto the registrar of companies. The report of the auditor was unqualified anddid not include a reference to any matters to which the auditor drew attentionby way of emphasis without qualifying their report and did not contain astatement under section 498(2) or (3) of the Companies Act 2006.

Going concern

The directors have reviewed the financial resources available to the group and have concluded that the group is a going concern. This conclusion is based upon, amongst other matters, a review of the group's financial projections together with a review of the cash and committed borrowing facilities available to the group.

2. Segmental reporting

As previously reported, United Utilities has reshaped its portfolioover the last few years, from a group with a wide-ranging set of activitiesand interests, such as telecommunications, business process outsourcing, gasand electricity distribution and metering and international utilityoperations, into a focused regulated UK water and wastewater business. Thegroup completed its non-regulated disposal programme in November 2010 and theresidual non-regulated activities now represent less than 2% of operatingprofit.

The board of directors of United Utilities Group PLC (the board) are provided with information on a single segment basis for the purposes of assessing performance and allocating resources. The board reviews revenue, underlying operating profit, operating profit, assets and liabilities at a consolidated level.

In light of this, the group has a single segment for financial reporting purposes and the segmental information presented in previous periods is no longer required to be disclosed separately within this note.

Earnings per share

Basic and diluted earnings per share are calculated by dividing profit after taxation by the following weighted average number of shares in issue:

INDEPENDENT REVIEW REPORT TO UNITED UTILITIES GROUP PLC

Introduction

We have been engaged by the company to review the condensed set offinancial statements in the half yearly financial report for the six monthsended 30 September 2011 which comprises the consolidated income statement, theconsolidated statement of comprehensive income, the consolidated statement offinancial position, the consolidated statement of changes in equity, theconsolidated statement of cash flows and the related explanatory notes. Wehave read the other information contained in the half yearly financial reportand considered whether it contains any apparent misstatements or materialinconsistencies with the information in the condensed set of financialstatements.This report is made solely to the company in accordance with theterms of our engagement to assist the company in meeting the requirements ofthe Disclosure and Transparency Rules ("the DTR") of the UK's FinancialServices Authority ("the UK FSA"). Our review has been undertaken so that wemight state to the company those matters we are required to state to it inthis report and for no other purpose. To the fullest extent permitted by law,we do not accept or assume responsibility to anyone other than the company forour review work, for this report, or for the conclusions we have reached.

Directors' responsibilities

The half yearly financial report is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half yearly financial report in accordance with the DTR of the UK FSA.

As disclosed in note 1, the annual financial statements of thegroup are prepared in accordance with IFRSs as adopted by the EU. Thecondensed set of financial statements included in this half-yearly financialreport has been prepared in accordance with IAS 34 Interim Financial Reportingas adopted by the EU.Our responsibility

Our responsibility is to express to the company a conclusion on the condensed set of financial statements in the half yearly financial report based on our review.

Scope of review

We conducted our review in accordance with International Standardon Review Engagements (UK and Ireland) 2410 Review of Interim FinancialInformation Performed by the Independent Auditor of the Entity issued by theAuditing Practices Board for use in the UK. A review of interim financialinformation consists of making enquiries, primarily of persons responsible forfinancial and accounting matters, and applying analytical and other reviewprocedures. A review is substantially less in scope than an audit conducted inaccordance with International Standards on Auditing (UK and Ireland) andconsequently does not enable us to obtain assurance that we would become awareof all significant matters that might be identified in an audit. Accordingly,we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half yearly financial report for the six months ended 30 September 2011 is not prepared, in all material respects, in accordance with IAS 34 as adopted by the EU and the DTR of the UK FSA.
