Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what recent estimate he has made of the total lifetime payments to participants under the British Renewable Heat Initiative scheme through to 2042 for the (a) domestic and (b) non-domestic scheme.

The Renewable Heat Initiative (RHI) will pay participants until March 2041 and BEIS has so far committed £6,414million for expenditure until financial year 2022/23. The total lifetime payments estimates are inherently uncertain as they depend on the future volume of heat that will be produced and on the future tariffs at which the heat produced will be paid.
