Payments to participants on the Renewable Heat Incentive are funded through Annual Management Expenditure (AME) rather than Department Expenditure (DEL). Once all heat readings are submitted, we expect the cumulative AME spend on the RHI to the end of 2018/19 to be approximately £2.68bn.
Ofgem e-Serve administers the scheme on behalf of the Department alongside a number of other schemes. Funding for delivering those schemes was just over £19 million in 2018/19.
In relation to value for money, this is assessed as part of regular Impact Assessments, the last of which was published in February 2018.
