New Policy Impact: The Nuclear RAB Levy

Q2-2026 isthe first full quarter where the Nuclear Regulated Asset Base (RAB) model appears on all commercial bills.
- What it is: A small levy (approx. 0.35p/kWh) added to bills to provide a direct subsidy for the construction of Sizewell C.
- The Long-term Outlook: While this adds a small immediate cost, the policy intent is to lower long-term volatility by reducing the UK's dependence on international gas markets (and the geopolitical shocks of the Middle East).
