Quarterly Management Statement – Q4 2025

Santander UK Group Holdings plc

Quarterly Management Statement

for the twelve months ended 31 December 2025

Mike Regnier, Chief Executive Officer, commented:

"In 2025, we made excellent progress in our ambition to become the best bank for customers, driven by the launch of innovative new products including our Edge Explorer current account and the Navigator Global platform for businesses looking to expand overseas. We invested in upgrading our branch network and supporting our communities and local businesses, with new Work Cafés providing banking services alongside free shared workspaces. Our focus on creating a digital bank with a human touch delivered improved retail customer NPS scores.

Our 2025 results show strong business performance, with an increase in profit before tax to £1,510m benefitting from higher income and lower costs, as well as lower provision charges. In 2025, our gross mortgage lending increased by £9.2bn and customer deposits by £6.8bn and, looking ahead, we expect to see net lending growth continue. It is vital that the regulatory and fiscal environment is conducive to the banking sector helping people get onto the housing ladder or move home, and supporting businesses of all sizes. Healthy banks are critical for a healthy UK economy.

The most significant change in 2026 is expected to be the acquisition of TSB1, for which we hope to receive regulatory approval in the first half of the year. This landmark acquisition will create the UK's third-largest bank by personal current account balances, enhancing the profitability of Santander UK and creating stronger competition and choice for customers.

In Q1 2026, I will step down as CEO following an exciting four years that have seen Santander UK become a more efficient, customer-centric, techdriven bank, offering better products and returning to growth in loans and deposits to deliver greater value for shareholders. Over this time, we have worked closely and effectively with Banco Santander to harness local and global capabilities. I am hugely proud of all my colleagues for their dedication and hard work. As the TSB acquisition exemplifies, our progress has led to significant investment by Banco Santander in the UK, demonstrating confidence in its long-term economic potential and a strategic commitment to UK customers."

Strong liquidity and funding, with our capital position well above regulatory requirements; we remain focused on capital efficiency

Strategic update

• We will continue to work closely with Banco Santander, harnessing group-wide expertise to deliver efficiencies and services for customers.

Outlook4

• We expect to see net lending growth continue in 2026.

• Banking NIM is expected to be stable in 2026. Our structural hedge position keeps us well positioned for further Bank Rate reductions.

• Cost of risk is expected to continue to trend up towards pre-pandemic levels, following a period of credit impairment write-backs in 2024.

• We expect further cost efficiencies in 2026, driven by simplification and automation of our business.

Income statement summary

2025 profit before tax up 14% vs 2024

• Net interest income increased 2%, driven by lower cost of deposits and supported by our structural hedge.

• Non-interest income was up 4%, mainly due to higher retail and corporate fee income.

• Operating expenses were down 3%, driven by simplification and automation, including a 12-month headcount reduction of over 2,700 FTE.

• Credit impairment charges were up £123m, trending to pre-pandemic levels after a period of write-backs in 2024, as previously guided.

• Provisions for other liabilities and charges were down 15%, mainly due to a lower provision charge in 2025 relating to historical motor finance commission payments, partly offset by higher transformation related charges, including £42m in charges relating to changes to our branch network3 in Q1-25 and other restructuring charges.

Historical motor finance commission payments

Further to the publication of the FCA's consultation paper on 7 October 2025 regarding a proposed industry-wide motor finance consumer redress scheme (Consultation), which followed the Supreme Court judgment of 1 August 2025 in Hopcraft, Wrench and Johnson (Hopcraft), the Santander UK group has reassessed the potential financial impact arising from motor finance related redress payments. On 3 December 2025, the FCA extended the pause on the handling of motor finance discretionary commission arrangement (DCA) and non-DCA commission complaints until 31 May 2026. A claim against SCUK, Santander UK and others in the Competition Appeals Tribunal which concerns SCUK's historical use of DCAs in respect of used car financing is currently paused until the end of March 2026.

The Santander UK group recognised a provision of £295m in its financial results for 2024. This provision was determined based upon the information then available. It included estimates for operational and legal costs and potential awards based on various scenarios and used a range of assumptions, including the possible outcome of an appeal to the Supreme Court in 2025 of the Court of Appeal's decision in Hopcraft.

The Santander UK group responded to the Consultation on 12 December 2025 and continues to engage constructively with the FCA in respect of its detailed consideration of the Consultation proposals. Based on its detailed consideration, the Santander UK group considers that there remains significant uncertainty regarding the ultimate outcome of the Consultation. The Santander UK group has updated its range of scenarios which has resulted in an additional estimated charge of £183m, increasing the total provision to £461m. This continues to include estimates for operational and legal costs and potential awards reflecting an increased likelihood of a higher number of cases than had previously been predicted as eligible for redress as well as an increased possibility that a remedy is sought to be imposed which extends beyond reversing any damaging financial consequences caused by any unfair relationships. The provision is based on various scenarios using a range of assumptions, including potential changes to the proposed scheme following responses to the Consultation or publication of the FCA's final scheme rules. There continue to be significant uncertainties as to the nature, extent and timing of redress payments. The ultimate financial impact could be materially higher or lower than the amount provided.

Balance sheet summary1

Prudent approach to risk evident across our customer loan portfolio. Broad based growth across all segments

• Mortgages: higher gross mortgage lending in 2025 of £25.3bn (2024: £16.1bn) with £14.7bn in H2-25 and £10.6bn in H1-25.

• Credit Cards: 54% (Dec-24: 56%) of customers repay their full balance each month. 

• Unsecured Personal Loans: average customer balance of £6k (Dec-24: £6k).

• Overdrafts: relatively small balance of £0.4bn (Dec-24: £0.5bn).

• Business Banking: includes £0.6bn (Dec-24: £1.1bn) of BBLS with 100% Government guarantee.

• Consumer Finance: 98% (Dec-24: 95%) of lending is collateralised on vehicles.

• CCB: customers remain largely resilient with overall improvement in asset quality.

Customer deposits increased by £6.8bn in 2025, driven by growth across all segments

• Savings increased following a successful ISA season, successful deposit campaigns, including cahoot, and customer migration from Current Accounts.

• Cost of deposits continued to fall from last year's peak.

Notes:

1 See Appendix 6 for detailed balance sheet.

Credit quality

Loans in Stage 2 and Stage 3 improved, highlighting underlying asset quality and sale of high RWA mortgage assets 

• Mortgage loans in Stage 2 and 3 decreased, supported by the Q3-25 sale of high RWA mortgage assets. Stage 2 ratios increased across the smaller retail unsecured portfolios, mainly overdrafts, due to an increase in the SICR criteria for non-arrears Stage 2 loans. 

• CCB loans in Stage 2 and 3 decreased, driven by overall improvement in asset quality.

ECL provision

• ECL provision decreased by £57m to £813m (Dec-24: £870m), reflecting reductions across almost all portfolios. The decrease was mainly driven by mortgages due to refinance-related JA releases, economic updates and the sale of high RWA mortgages in Q3-25.

• 12-month gross write-off utilisation of £248m (2024: £230m).

Notes:

 1 Non-IFRS measure. See Appendix 1 for details.

Economic scenarios

Economic scenarios were updated for Q4-25 to reflect the latest market data, including expectations for inflation and Bank Rate

• Base case was updated to reflect back data changes to GDP pushing up growth. We anticipate a modest rise in unemployment as firms adjust to the higher cost of employment.

• Upside scenario incorporates a quicker economic performance, driven by an improvement in the supply side of the economy.

• The downside scenarios capture a range of risks, including further escalation of geopolitical events, continuing weaker investment (reflecting the unstable environment and higher cost of employment), a continuing and significant mismatch between job vacancies and skills (as well as a smaller labour force) and a return to upside inflation surprises causing interest rates to remain at higher levels for longer.

Notes:

1 Our Q4-25 forecast used for ECL calculation.

2 GDP, HPI and CRE start is taken from the level at Q3-25.

Capital, liquidity and funding

Capital ratios well above regulatory requirements

• CET1 capital ratio increased to 15.7% due to ongoing organic capital generation and a no-dividend decision for 2025, partially offset by higher RWAs. In anticipation of the proposed acquisition of TSB by Santander UK (subject to regulatory approvals and other consents), in Aug-25 the Board passed a resolution to cancel the dividends that were accrued in the CET1 capital ratio calculations at Jun-25.

• UK leverage exposure increased to £251.7bn (Dec-24: £242.4bn) as a result of active balance sheet management.

Strong liquidity position

• LCR of 166% (Dec-24: 156%), increased largely due to a reduction in the customer funding gap in 2025.

• LCR eligible liquid assets surplus of £20.1bn to regulatory requirements.

• NSFR of 135% (Dec-24: 136%).

• LCR eligible liquidity pool of £51.0bn (Dec-24: £47.8bn), includes £31.7bn cash and central bank reserves (Dec-24: £32.2bn).

Diversified funding across well-established issuance programmes

• LDR of 105% (Dec-24: 108%), with higher customer loans and customer deposits, and an improved customer funding gap.

• Issued £10.5bn Sterling equivalent term issuance in 2025, including Covered Bond, RMBS, AT1 and Senior Unsecured issuances2. 

• Repaid £7.1bn in TFSME in 2025, with an outstanding balance of £3.9bn at Dec-25, of which £2.5bn is due for repayment in 2027 and £1.4bn is due in 2031.

• We expect to issue £8.0 to 12.0bn of term issuance in 2026, including the £1.25bn equivalent issued in Jan-26.

Structural hedge evolution

• Santander UK plc's structural hedge position decreased to £103bn at Dec-25 (Dec-24: £110bn), with an average duration of 2.3 years (Dec-24: 2.4 years).

• Our structural hedge position keeps us well positioned for further Bank Rate reductions.

Significant Risk Transfers (SRTs)

• As part of our strategy aimed at driving balance sheet optimisation, Santander UK completed four SRTs in the year (2024: five).

• 2025 transactions covered Retail & Business Banking, Corporate & Commercial Banking and Consumer Finance assets.

Summary segmental information

RoTE Overview

Appendix 2 - Interest rate risk

The table below shows how our net interest income would be affected by a parallel shift (both up and down) applied instantaneously to the yield curve. Sensitivity to parallel shifts represents the amount of risk in a way that we think is both simple and scalable.

Notes:

1 Based on modelling assumptions of repricing behaviour.

Appendix 3 - Mortgages

In ternal transfers of £36.5bn in 2025. Internal transfers relate to current customers switching from one product to another.

Balance sheet information

Appendix 7 - Banco Santander's acquisition of TSB from Sabadell

On 1 July 2025, Banco Santander announced that it reached an agreement to acquire 100% of TSB from Sabadell, with a valuation of £2.65bn in an all-cash transaction. Completion of the transaction is expected to occur in the first half of 2026. The transaction remains subject to regulatory approvals.

TSB is a well-established UK retail bank with a nationwide network of 175 branches and outlets, and a growing digital presence. It serves approximately 5 million customers, primarily in the personal and small business segments, with £34bn in mortgages (2% market share in the UK) and £35bn in deposits.

The acquisition further strengthens Banco Santander's position in one of its core markets, expanding its customer base and lending capacity across the UK. Banco Santander intends to integrate TSB in the Santander UK group. Santander UK would become the third largest bank in the country by personal current account balances and number four in mortgages. The integration would be subject to regulatory and other approvals.

When combined, the two banks would serve nearly 28 million retail and business customers nationwide, giving TSB customers access to Banco Santander's international network and allowing them to benefit from Banco Santander's leading technology platforms.

Proven integration capability

Banco Santander is one of the largest international investors in the UK financial services industry, having successfully acquired and integrated Abbey National plc in 2004 and both Alliance & Leicester plc and the Bradford & Bingley savings business in 2008. It has a proven track record in successful banking platform migrations.

By integrating technology across Santander UK and TSB, Banco Santander expects to unlock substantial operational efficiencies and support longterm profitability through a simplified, scalable digital banking model. We are fully committed to ensuring a seamless integration, by leveraging our market leading technology and significant experience. Maintaining the highest levels of service for customers across both banks will be a key priority and we will support all colleagues through the transition, as we invest in building a stronger bank for the future.

Appendix 8 - Other

Retail NPS

Our customer experience research was subject to independent third party review. We measured the main banking NPS of 17,730 consumers on a six month basis using a 11-point scale (% Top 2 - % Bottom 7). The reported data is based on the six months ended 31 December 2025, and the competitor set included in the ranking analysis is Barclays, Halifax, HSBC, Lloyds Bank, Nationwide, NatWest Group (NatWest & RBS) and TSB. 

Dec-25: NPS ranked 6th for Retail, we note a margin of error which impacts those from 4th to 6th and makes their rank statistically equivalent. Dec-24: NPS ranked 5th for Retail, we note a margin of error which impacts those from 2nd to 6th and makes their rank statistically equivalent.
