What does heat pump installation in Chalfont St Giles involve?

We install air source heat pumps across Chalfont St Giles and the surrounding Buckinghamshire area. The Chilterns has a mix of property ages and types: detached period homes, semi-detached post-war houses, modern developments. We check each property individually at the site survey to confirm suitability before recommending installation.

If your property is not suitable for a heat pump, we tell you honestly at the survey rather than after you have signed. That is the only way to build a reputation in a local market like Chalfont St Giles.

What do Chalfont St Giles homeowners ask about heat pumps?

The Boiler Upgrade Scheme (BUS) provides a £7,500 government grant towards an air source heat pump installation. You do not need to apply yourself: we apply on your behalf as an MCS-certified installer. The grant is deducted from your installation cost. To qualify, your property must have a valid EPC with no outstanding loft or cavity wall insulation recommendations.
Heat pumps work best in well-insulated homes with larger radiators or underfloor heating. They run at lower flow temperatures than gas boilers, so if your home loses heat quickly, it may need insulation improvements first. Our site survey assesses this honestly: we will tell you if it is not the right time for a heat pump.
After the £7,500 Boiler Upgrade Scheme grant, a typical air source heat pump installation costs from around £2,995 depending on the property and system size. Without the grant, costs typically range from £10,495 to £15,000. We give you a fixed all-in price at the site survey.
In a well-insulated home, an air source heat pump can be cheaper to run than a gas boiler, especially as gas prices have risen. Heat pumps have a Coefficient of Performance (COP) of 2.5 to 4: meaning for every 1 unit of electricity they use, they produce 2.5 to 4 units of heat. However, electricity is still more expensive per kWh than gas, so insulation quality matters.
Most air source heat pump installations fall under permitted development rights in England and do not need planning permission, provided the unit is not visible from a highway and meets size and noise restrictions. We confirm at the survey whether your installation qualifies.
