Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what estimate they have made of the average administrative cost incurred by Ofgem per voucher issued under the Boiler Upgrade Scheme for each financial year since its inception.

The Government has not published the average administrative cost incurred by Ofgem per voucher issued under the Boiler Upgrade Scheme.

The scheme, now part of the Government’s Major Project Portfolio, will be included in the 24-25 National Infrastructure and Service Transformation Authority (NISTA) Annual Report publication, which will disclose whole life scheme costs.
