These Statutory Instruments continue the Warm Home Discount Scheme in England and Wales until March 31, 2031, re-enacting and amending provisions from the 2022 Regulations to combat fuel poverty.
The scheme mandates obligations on energy suppliers, primarily through a core spending obligation requiring the provision of a £150 prescribed rebate to eligible 'core group customers' identified by the Secretary of State, and a non-core spending obligation covering industry initiatives like energy efficiency improvements, advice provision, and debt write-off, all administered and enforced by the Gas and Electricity Markets Authority (the Authority).

These changes apply to all licensed electricity suppliers who must either produce Renewables Obligation Certificates (ROCs) or make cash buy-out payments to the Gas and Electricity Markets Authority (Ofgem).
