In the UK, the actual cost of an air source heat pump (ASHP) is mainly divided into two parts: initial installation costs and ongoing operating costs.
| Property Type | Typical Cost Before Grant | Typical Cost After £7,500 Grant |
| 1-2 Bed Flat / Small Terrace | £7,000 - £10,000 | £0 - £2,500 |
| 3 Bed Semi-Detached | £8,000 - £13,000 | £500 - £5,500 |
| 4+ Bed Detached / Large Home | £10,000 - £18,000+ | £2,500 - £10,500+ |
1. Initial Installation Costs
The total installation cost of an air source heat pump varies greatly depending on the specific circumstances of the house. The following details how size affects the price.
1) Property Type | Typical Price Before Subsidy | Typical Price After £7,500 Subsidy
2) 1-2 Bedroom Apartment/Small Townhouse | £7,000 - £10,000 | £0 - £2,500
3) 3 Bedroom Semi-Detached House | £8,000 - £13,000 | £500 - £5,500
4) 4-Bedroom and Above Detached House/Large House | £10,000 - £18,000 and above | £2,500 - £10,500 and above
2. Government Subsidies
In the UK, the Boiler Upgrade Scheme (BUS) provides a £7,500 subsidy for installing air source heat pumps in England and Wales. Your installer will usually apply for this subsidy on your behalf, reducing the final cost you will pay. Scotland also has access to support through the Scottish Home Energy Grant and Loan Scheme.
3. Operating Costs
While initial costs may be higher, the operating costs of heat pumps are typically comparable to or even lower than those of gas boilers due to their high efficiency.
1) Efficiency: Heat pumps can be over 300% efficient, meaning they generate 3 units of heat for every 1 unit of electricity consumed.
2) Annual Costs: The estimated annual operating cost for a typical household is around £400 to £600. The exact cost depends on various factors, such as the insulation of the house, the size of the system, electricity prices, and outdoor temperatures. Using a dedicated electricity rate package for heat pumps can further reduce costs.
4. Key Factors Affecting “Actual” Costs
Please remember that the final cost usually includes more than just the heat pump unit itself. The total installation quote typically includes:
1) The heat pump system and hot water tank
2) Installation labor and design
3) Necessary home upgrades, such as larger radiators, new piping, or better insulation, which can sometimes account for a significant portion of the bill.
Taking these factors into account, the best way to get an accurate cost estimate for your home is to ask an MCS-certified installer for a detailed quote based on heat loss.
