What is the Nuclear RAB Contribution on my bill?

The Nuclear Regulated Asset Base (RAB) Contribution is a small, regulated charge introduced by the UK Government and regulated by Ofgem. It funds the construction of new nuclear power stations, which are vital for providing clean, reliable electricity. Similar to CCL or VAT, this charge is applied outside of your fixed-price contract.

By contributing during construction, financing costs (like loan interest) are reduced. This means the overall cost of the project is lower, saving consumers an estimated £30–£80 billion compared to other funding models.

No. This is not a supplier fee. The charges are set by Ofgem and collected by all UK suppliers. Funds are passed directly to the Low Carbon Contracts Company (LCCC) to support nuclear projects.

From 1 October to 31 October 2025, the charge will be £0.00. From November onwards, it will be a small amount, applied to your energy bill.

Nuclear power provides continuous, low-carbon electricity. It reduces reliance on imported fossil fuels, supports the UK’s Net Zero 2050 target, and ensures a more stable and affordable energy system in the future.
