Heat pump installation in Slough
Prices are valid for 2026 and are indicative
Here you can see what heat pump installation in Slough costs on average. We explain what the price consists of and which local factors have the biggest impact.
The UK government's Boiler Upgrade Scheme (BUS) offers a £7,500 grant for air and ground source heat pumps, significantly reducing the cost for eligible homeowners. Installation must be carried out by an MCS-certified installer to qualify.
Typical total costs range from £7,000 to £18,000 for an air source heat pump, including installation. Ground source systems run from £15,000 to £35,000. The right system size depends on your home's heat demand — proper insulation beforehand can reduce running costs by up to 30%.

Cost factors
Heat pump installation costs in the UK are made up of several components. Prices below are before any BUS grant deduction.
- Heat pump unit (ASHP): £4,000–£10,000
- Installation labour: £2,000–£5,000
- Hot water cylinder: £600–£1,500
- Pipework and buffer tank: £500–£1,500
- Electrical work and smart controls: £400–£1,000
- Scaffolding (if needed): £300–£800
After the £7,500 Boiler Upgrade Scheme grant, many homeowners pay £3,000–£10,500 net. VAT is 0% on heat pump installations under the Energy Saving Materials relief.
Why do prices vary?
- Heat pump type: Air source (£7k–£18k) is cheaper than ground source (£15k–£35k). Monobloc systems are simpler to install than split systems.
- Home size and heat loss: A proper heat loss calculation (required by MCS standards) determines the kW output needed. Poorly insulated homes need a larger, more expensive unit.
- Existing heating system: Homes with underfloor heating or large radiators work best. Upgrading radiators to low-temperature versions adds £100–£300 each.
- Hot water setup: Most homes need a new hot water cylinder (£600–£1,500) as heat pumps are not compatible with combi boilers.
- Insulation standard: Well-insulated homes (EPC C or above) achieve lower running costs. Poor insulation can double annual running costs.
- Location and climate: Northern Scotland and other colder regions may need a larger unit, but cold-climate ASHPs now operate efficiently at -20°C.
