Northern Ireland Renewable Obligations cost (ROCs) adjustment and Climate Levy Change (CCL)

ROCs changes

From 1 April 2026, the Northern Ireland Renewables Obligation Cost (ROCs) decreased from 19.3% to 18.4% ROCs per MWh of electricity supplied. The buyout price for each ROC increased from £67.06 to £69.34.

These changes equate to an decrease of 0.02 pence per kWh (£0.0002 per kWh).

We’ll apply the decreased pass-through costs to your bill from 1 April 2026. For more information on this see OFGEM website.

Climate Change Levy (CCL)

From 1 April 2026, the Climate Change Levy (CCL) rate increased from 0.775 pence (£0.00775) per kWh to 0.801 pence (£0.00801) per kWh. Further information on CCL can be found here.

SSE Airtricity expects the next change in pass-through costs to be from 1 October 2026 which will arise from the annual review of inter alia transportation and distribution use of system charges, Single Electricity Market (SEM) costs and the Public Service Obligation (PSO) levy.
