Feed-in Tariffs (FiT) scheme: indexation changes
We're seeking views on proposed changes to inflation indexation for the Feed-in Tariffs (FiT) scheme.
Detail
The UK government is proposing changing the inflation indexation calculation for the Renewable Obligation (RO) and Feed-in Tariffs (FiT) schemes, from the Retail Price Index (RPI) to the Consumer Price Index (CPI):
- for the Renewable Obligation (RO) scheme, the inflation indexation calculation for the buy-out price would be changed by Ofgem from RPI to CPI
- for the Feed-in Tariffs (FiT) scheme, the annual tariff adjustment calculation would be changed from RPI to CPI
The indexation change would come into effect in April 2026 and would affect all UK generators on the RO and FiT schemes.
Changes to inflation indexation would lower the annual subsidy uplifts for generators and reduce the cost of these schemes for UK consumers.
