Renewables Obligation (RO) scheme: indexation changes
We're seeking views on proposed changes to inflation indexation for the Renewables Obligation (RO) scheme.
We have extended the consultation closing date from 28 November to 2 December 2025 to allow more time for responses.
The UK government is proposing changing the inflation indexation calculation for the Renewables Obligation (RO) and Feed-in Tariffs (FiT) schemes, from the Retail Price Index (RPI) to the Consumer Price Index (CPI):
- for the Renewables Obligation (RO) scheme, the inflation indexation calculation for the buy-out price would change from RPI to CPI
- for the Feed-in Tariffs (FiT) scheme, the annual tariff adjustment calculation would change 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.
