Calculate the cost of a heat pump system

Heat pumps are a green way to heat your home and its water, and modern systems are more efficient than ever before.

To calculate the cost of a heat pump, a number of factors need to be considered. Each property has its own identity and quirks, but it’s still possible to get an accurate calculation for the costs associated with installing an Air Source Heat Pump (ASHP) or Ground Source Heat Pump (GHSP).

Luckily, we’ve created a handy calculator for working out the costs, and it also calculates your long-term savings from installing a heat pump system at your property. We take into account your earnings from the UK government’s Renewable Heat Incentive (RHI) scheme, and identify which technology is most suited to your property and its area.

An overview of costs

Remember: These costs are offset by government incentive schemes, and installation of heat pump systems can be financed in a number of ways. Renewable energy technologies save money in the long-term, so the following numbers can always be justified. 

To install a Ground Source Heat Pump (GSHP), the cost can typically be between £13,000 – £20,000. The costs per kW of peak heat output varies from up to £2,400 for the smaller systems (5 – 10 kW), to below £2,000 for larger systems (10 – 20 kW). Bore-hole and vertical systems are typically more expensive than horizontal systems, which are placed around loops in trenches. A general rule of thumb is the bigger the system size, the smaller the unit price per kW.

Air Source Heat Pumps (ASHP) cost between £7,000 – £11,000. The full cost is dependent on the size and layout of your property, the current heating system in situ, the quality of insulation at the property, and the desired temperature for the building’s rooms. For Air-to-Air Heat Pumps, the cost per kW of peak heat output varies from £1,150 for small systems to under £600 for larger systems. For an Air-to-Water Heat Pump, cost per kW of peak heat output ranges from £1,200 for small systems to under £550 for a larger system.
