The Boiler Upgrade Scheme (BUS) is a government grant scheme in England and Wales that provides upfront vouchers to help homeowners and small landlords replace existing heating systems with low-carbon alternatives. The scheme is administered by Ofgem and is available to MCS-certified installers.
Current voucher values:
- Eligible off-gas-grid air-to-water or ground source heat pump: £9,000 until 31 March 2027
- Standard air-to-water, ground source or water source heat pump: £7,500
- Eligible residential air-to-air heat pump: £2,500
Why is the off-gas-grid grant higher?
The temporary £9,000 grant is designed to help eligible off-gas-grid households move away from fuels such as oil and LPG. It is £1,500 higher than the standard £7,500 hydronic heat-pump grant.
The uplift is time-limited. The installer must make an eligible application under the current rules, so confirm the grant value before agreeing to work.
BUS eligibility requirements
Suitability: is my oil-heated home right for a heat pump?
Heat pumps work most efficiently in well-insulated homes with low-temperature heat distribution (underfloor heating or large radiators). Key factors to discuss with an installer:
- Level of insulation in walls, loft and floor
- Current radiator sizing and hot water cylinder capacity
- Outdoor space for an air source unit or land/water source for ground source
- Whether your existing EPC flags any recommended improvements first
Do not cancel your oil or LPG contract yet
BUS vouchers must be confirmed before installation begins. Allow time for an installer survey and MCS certification. Speak to an MCS-certified installer before making any changes to your existing system.
