What is the Nuclear RAB Levy?
The Nuclear Regulated Asset Base (RAB) Levy is a new government scheme designed to support the funding of nuclear energy generation.
From the 1 November 2025, all energy suppliers will have to pay into the Nuclear RAB Levy to support the development and eventual running of nuclear generation in the UK. As a result of this, suppliers will need to start recovering these costs from electricity customers.
The levy will apply to all electricity suppliers.
The levy will also apply to all electricity consumers, apart from Energy Entensive Industries (EIIs) who will be entitled to exemptions from the charge.
How is the Nuclear RAB Levy charged?
The Nuclear RAB Levy charge is included in your contracted Unit Rates.
As the rate of the Nuclear RAB Levy is only reviewed and published on a quarterly basis by the Low Carbon Contracts Company (LCCC), fixed prices will include some element of forecasted rates beyond the published rates period.
If you are an EII customer, you will be periodically reconciled throughout your contract, so you are reimbursed for any Nuclear RAB Levy charges that were included in your Unit Rates.
Why is the Nuclear RAB Levy important?
- Nuclear provides stable, low-carbon baseload power, reducing reliance on fossil fuels.
- It supports the UK’s target of 95% low-carbon electricity by 2030.
- While bills may rise slightly now, the model aims to reduce long-term energy costs by lowering financing risks.
