Consultation description

This consultation is in 2 parts.

Part 1: Amendments to the Boiler Upgrade Scheme

Part 1 seeks views on proposed amendments to the Boiler Upgrade Scheme (BUS) which provides grants to support property owners in transitioning to low carbon heating (LCH) systems.

The proposed changes are designed to increase access, stimulate further demand and enhance existing consumer protections. They include:

  • allowing new heat pump purchase options alongside the BUS grant
  • expanding eligibility for LCH technologies
  • reviewing potential barriers to the consumer installation journey
  • enhancing consumer protection by simplifying certification requirements and requiring installers to deduct grants upfront

  • require the Microgeneration Certification Scheme (MCS) as the sole certification scheme for clean heat installations delivered through:
    • BUS
    • Energy Company Obligation 4
    • Warm Homes: Local Grant
    • Warm Homes: Social Housing Fund
  • remove the option for multiple certification schemes to certify installations.
