Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of the indexation of feed in tariffs to align with CPI rather than RPI from financial year 2026-27 on community energy schemes.

Changing indexation of the Feed‑in Tariffs scheme from RPI to CPI is estimated to reduce average revenue for a generator remaining on the scheme until 2036/37 by around 4.2%, compared with a scenario where indexation is unchanged. Generators that exit the scheme earlier would experience a smaller average impact. The available data does not allow for analysis on specific groups of generators such as community energy schemes. An analytical annex, including an assessment of the potential impacts of this policy, was published alongside the government response.
