Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government, with reference to Ofgem's Boiler Upgrade Scheme Annual Report 2023–24, what assessment they have made of the discrepancy between (1) Ofgem's reported overall fraud and error rate of 1.18 per cent of total payments under the Boiler Upgrade Scheme, and (2) the 6.4 per cent non-compliance rate identified through statistical audits; what reasons they have identified for this discrepancy; and what the estimated overall non-compliance rate is for the scheme.

The Boiler Upgrade Scheme is administered by Ofgem on behalf of the government. Given the nature of the data requested, Ofgem will write to the noble Lord and a copy of the letter will be placed in the Libraries of the House.
