Detail of outcome
Part 1: Amendments to the Boiler Upgrade Scheme
(published 18 November 2025)
As a result of the consultation, we will:
Expand system eligibility
- begin to provide grants to support the installation of
air-to-air heat pumps (AAHPs) in domestic properties with
a value of £2,500
- begin to provide grants to support the installation of heat
batteries with a value of £2,500, once appropriate product,
design and installation standards have been implemented,
including robust consumer protections
- amend scheme eligibility criteria to allow more installations
of heat pumps in combination with other electric heating
appliances
- allow the installation of exhaust air heat pumps
Third-Party Ownership agreements
- undertake further work on third-party ownership of
BUS-funded heating
systems to resolve complex interactions with the current
regulatory landscape before determining eligibility for the
scheme
Simplify the heat pump installation journey
- relax the requirement to provide a valid Energy Performance
Certificate (EPC) from 2026 to 2027
onwards
Enhance consumer protections
- assess the MCS Customer
Commitment as a consumer code before determining whether to
approve it for the scheme
Grant payments under the BUS
- introduce a requirement in the BUS regulations for installers to
deduct the grant amount from the upfront costs of the eligible
plant
Next steps
We will proceed to introduce scheme regulations to Parliament to
give effect to these changes, as parliamentary time allows. We
will announce the timing of these changes in the coming weeks and
provide guidance for installers and consumers on how the changes
will impact the application process.
