Written Question
Renewable Heat Incentive Scheme
Monday 24th February 2025

Asked by: Lord Colgrain (Conservative - Excepted Hereditary)

Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government, in the context of the 10-year recalibration requirement for Non-Domestic Renewable Heat Incentive (NDRHI) schemes; how many NDRHI schemes exist; how many NDRHI schemes are currently under review; and what is the mean time taken for the review of a scheme, from submission to sign-off.

Answered by Lord Hunt of Kings Heath - Minister of State (Department for Energy Security and Net Zero)

There are approximately 22,810 Non-Domestic Renewable Heat Incentive participants with meters that will need to comply with metering obligations. Currently 630 are under review by Ofgem, the scheme administrator. The time taken to complete a review is dependent on the quality and complexity of the participant’s submission, response time to requests for further information and the review caseload.
