Typical air source heat pump installation costs
For most UK homeowners, an air source heat pump usually costs between £7,000 and £14,000 to install. The final price depends on the size of the property, the heat demand, and the type of system chosen.
Smaller, well-insulated homes may come in at the lower end of the range. Larger homes, or properties that need more complex work, can cost more.
What affects the price?
The biggest factor is the size and efficiency of your home. A heat pump must be sized correctly to keep the property warm without wasting energy.
Installation complexity also matters. If your radiators need upgrading, your pipework needs changes, or a hot water cylinder is required, the total cost will rise.
Location can affect labour prices too. Some installers charge more in areas where demand is high or access is difficult.
Extra costs to budget for
Many homeowners need to factor in additional upgrades. These may include larger radiators, improved insulation, or a new thermostat and controls.
If your home is off the gas grid, you may already have electric heating or oil heating, which can make the switch more or less complicated. In some cases, groundwork or electrical upgrades are also needed.
Running costs should also be considered. While the upfront installation price can be significant, a heat pump may lower bills over time if your home is suitable.
Government support and grants
UK homeowners may be able to get help through the Boiler Upgrade Scheme. This grant can reduce the installation cost by £7,500 for eligible air source heat pumps in England and Wales.
Eligibility rules apply, and the system must be installed by an MCS-certified installer. Scottish homeowners may have access to different support schemes, depending on location and circumstances.
It is worth checking current grant details before getting quotes. Support can make a major difference to the overall cost.
Getting a realistic quote
The best way to understand the cost is to get several quotes from approved installers. A proper survey should assess your home, heating needs, and any upgrades required.
Cheap quotes can be misleading if they do not include essential extras. Make sure you ask whether the price covers design, installation, controls, testing, and aftercare.
In many cases, the cheapest option is not the best value. A well-designed system can save money over time and improve comfort throughout the home.
