Asked by Jayne KirkhamLabour (Co-op)Department for Energy Security and Net ZeroTabled Answered 18 December 2025UIN 100172

The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of 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) on existing renewable-energy system owners.

Answered by Michael Shanks

The Government has consulted on proposed changes to how support provided through the Feed-in Tariffs and Renewable Obligation schemes is adjusted for inflation. The consultation was accompanied by an analytical annex which set out the potential impacts of the policy. Updated analysis will be published alongside the Government Response next year.
