Discover How Grants Slash Your Heat Pump Installation Cost
If you’re staring at the upfront heat pump installation cost and wondering how to make it more manageable, you’re not alone. UK homeowners can tap into a host of government-backed schemes that chop thousands off the sticker price. Whether you fancy a sleek ductless system or a central air source heat pump to replace your ageing boiler, there’s a grant designed to ease the burden.
In this guide, we’ll unpack the Boiler Upgrade Scheme, VAT relief pilots, local council grants and more—all finely tuned to help you slash that heat pump installation cost. Plus, you’ll see how our expert team at The Heat Pumps (Megawave) can tailor your project, handle paperwork and ensure you squeeze every last penny out of your rebate. Megawave: Eco-Friendly Heating Revolution for Lower Heat Pump Installation Cost
Government-Backed Savings Explained
The Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme launched to replace fossil-fuel boilers with low-carbon alternatives. For air source heat pumps, it offers:
- £5,000 grant per installation
- Open to owner-occupiers, landlords and self-builders
- Eligible for both single-unit homes and small multi-unit blocks
This rebate effectively lowers your heat pump installation cost by a hefty chunk. Imagine shaving off £5k before you even start drilling holes. Sweet.
VAT Relief on Heat Pumps
Pilots in select regions test a reduced VAT rate (5%) on air source heat pump equipment and installation. At standard 20% VAT, a £12,000 system costs £14,400. At 5%, it’s just £12,600. That’s £1,800 in your pocket. Check if this relief is live in your postcode—and act fast, as it’s often tied to experimental government schemes.
Local Authority and Council Grants
Beyond national schemes, many councils top up grants or run targeted pilots:
- Energy Company Obligation (ECO4) funding for low-income households
- Local green funds offering £500–£1,500 per installation
- Council-managed interest-free loans to spread your heat pump installation cost over 5–10 years
Each council has its own rules. Your best bet? Head online or call your local authority’s energy team. They’ll point you towards every penny you can claim.
Renewable Heat Incentive (RHI) Alternatives
While the Domestic RHI wound down in April 2022, follow-on support lives on via BUS and ECO4. The old RHI paid quarterly tariffs for 7 years—an attractive feature if you still qualify under transitional rules. Ask your installer about legacy RHI rates, especially if you applied before the cut-off.
Breaking Down the Heat Pump Installation Cost
Understanding the headline grants is only half the story. Break your total down into bite-sized chunks:
System Size and Property Type
- Smaller flats: single-unit ductless heat pumps
- Semi-detached and full-size homes: central heat pumps + radiators or underfloor heating
- New builds vs retrofits: simpler installs cost less than complex retro-fits
Zero-Carbon Refrigerants and Efficiency
High-efficiency units running on R290 or other zero-carbon refrigerants can carry a premium. Yet their improved CoP (Coefficient of Performance) slashes running costs long term. That initial outlay nudges your heat pump installation cost up by £500–£1,000, but you’ll recover that in energy savings within 2–3 years.
Installation Complexity
- Multi-storey dwellings often need extra pipework or electric boosting
- Outbuildings and extensions might require remote siting of the outdoor unit
- Grid capacity assessments, planning consents or Listed Building consents add to labour time
Maintenance and Aftercare
A well-maintained heat pump can run efficiently for 15–20 years. Our team offers annual servicing contracts from as little as £150 a year—an investment that keeps your system in tip-top shape and maximises efficiency, meaning your long-term heat pump installation cost stays low.

Real-Life Example: The Wright Family
The Wrights in Bristol replaced a 20-year-old gas boiler with a 10 kW air source heat pump. Their numbers:
- Headline system cost: £11,000
- Boiler Upgrade Scheme grant: –£5,000
- VAT relief (pilot area): –£1,000
- Council top-up (ECO4): –£750
- Out-of-pocket spend: £4,250
That’s a 61% reduction on the standard heat pump installation cost and projected annual savings of £600 on energy bills.
