Environmental Levy Changes – What They Mean for You

At UrbanChain, transparency is part of our promise. 

When government changes affect energy pricing, we believe you should know exactly what’s happening, why, and how it might impact you. 

The UK Government has announced a new national levy to fund the construction phase of Sizewell C.  

Nuclear Regulated Asset Base (NRAB): From November 2025, a charge of £3.455/MWh will apply, rising to £4.530/MWh in Q3 2026. 

These charges are set nationally and apply to all energy suppliers. UrbanChain is required by law to collect them. Customers with a valid Energy Intensive Industries (EII) exemption certificate will not be charged.
