Potential Changes to UK ROCs and FiTs Regimes

On 31 October 2025, the UK's Department for Energy Security and Net Zero published a consultation regarding potential changes to the indexation of Renewable Obligation Certificates ('ROCs') and Feed-in Tariffs ('FiTs'). The consultation outlines two proposals:

1. To bring forward the switch from RPI to CPI indexation from 2030 to 2026

2. To hold ROC and FiT payment levels at current rates until historical CPI aligns with RPI, after which CPI indexation would apply

The estimated benefit to the average household bill for 2026-27 is £4 under Proposal 1 and £13 under Proposal 2, excluding any consequential impacts such as increased cost of capital.[1]

Bluefield Solar has exposure to ROC and FiT revenues, reflecting its established portfolio of UK solar assets developed under these schemes. The Board and Investment Adviser are actively engaging with the consultation process and with Government stakeholders, noting that retrospective changes of this nature risk undermining investor confidence at a time when private capital is essential to delivering the UK's clean power ambitions and securing long-term energy resilience.

The Investment Adviser estimates that, if applied to Bluefield Solar's portfolio, the negative impact on NAV per ordinary share is estimated to be c.2% (c.2p) under Proposal 1 and c.10% (c.11p) under Proposal 2. These figures remain subject to further modelling and will be updated as more clarity emerges.

Bluefield Solar remains committed to supporting the UK's energy transition and will continue to advocate for policy stability and fair treatment of renewable investments.
