The main air source heat pump grant in East Anglia is the £7,500 Boiler Upgrade Scheme — available to most homeowners in Cambridgeshire, Norfolk and Suffolk, paid straight off your installation invoice. Combined with 0% VAT, a heat pump can cost as little as £500–£6,500 installed. Qualifying lower-income households can also access council-run Warm Homes schemes on top.
£7,500 Grant at a Glance
What is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is a UK government initiative designed to encourage homeowners to replace fossil fuel heating systems with low-carbon alternatives. Launched in April 2022, the scheme provides upfront capital grants to reduce the cost of installing heat pumps.
The grant was originally £5,000 but was increased to £7,500 in October 2023. The scheme budget has been nearly doubled to £295 million, and applications increased 67% in 2024 — demonstrating strong demand. The scheme is currently confirmed to run until at least March 2028. For a full breakdown of heat pump pricing and brand comparisons, see our heat pump costs guide. We install heat pumps across Cambridgeshire, Norfolk, and Suffolk.
Am I Eligible?
EPC Insulation Requirements
If your EPC recommends loft or cavity wall insulation, you must install this before applying for the BUS grant. We can arrange insulation as part of a combined package if needed.
How We Handle the Process
Free Home Assessment
We visit your property to assess insulation, radiators, and heating requirements. We check your EPC and confirm eligibility.
System Design & Quote
We design the optimal heat pump system and provide a detailed quote showing the cost before and after the £7,500 grant.
BUS Application
We submit your BUS application to Ofgem. This is typically approved within 2-3 weeks. You do not need to do anything.
Installation
Once the voucher is approved, we schedule and complete the installation. Typically 2-4 days for a full system.
You Pay the Net Cost
You only pay the invoice amount minus the £7,500 grant. The grant is paid directly to us by Ofgem — you never handle the money.

Heat Pump Grants in East Anglia: What Stacks With BUS?
The £7,500 Boiler Upgrade Scheme is UK-wide, but East Anglia households can often stack local support on top. Across Cambridgeshire, the Warm Homes: Local Grant is delivered by the Cambridgeshire Energy Retrofit Partnership through Action on Energy — funding insulation and low-carbon heating for lower-income households in EPC D–G homes. In Norfolk, the Norfolk Warm Homes partnership runs equivalent support through the district councils, and in Suffolk, Warm Homes Suffolk covers qualifying households across the county. Eligibility is broadly a household income under £36,000 or receipt of a means-tested benefit, with flexibility for those just above the thresholds.
Our region is also one of the best places in Britain to run a heat pump: East Anglia's mild, dry climate means higher seasonal efficiency, and the large number of off-gas villages around Ely, Newmarket, Thetford and the Fens — where oil heating is standard — makes the switch especially valuable. We handle the whole BUS application for every air source heat pump installation, and we check your local council scheme eligibility at the free survey.
Frequently Asked Questions
Who is eligible for the Boiler Upgrade Scheme?
You must own your property (or be a landlord) in England. The property must have a valid EPC (Energy Performance Certificate) and not be a new build. There must be no outstanding recommendations for loft or cavity wall insulation on the EPC. The existing heating system must use fossil fuels.
Can I get the BUS grant for a rental property?
Yes. Landlords can apply for the BUS grant for rental properties, provided the property meets all eligibility criteria. The tenant does not need to apply — the landlord (or their appointed installer) handles the application.
How long does the BUS application take?
We submit the application after your survey and system design. Ofgem typically processes applications within 2-3 weeks. Once approved, the voucher is valid for 3 months, giving you time to schedule the installation.
Can I combine the BUS grant with other funding?
You can combine the BUS grant with 0% VAT on the heat pump installation. However, you cannot combine it with ECO4 funding for the same measure. Other energy efficiency improvements (insulation, solar panels) can be funded separately.
