The Sussex Heating Care Company Ltd
In 2026, a typical air source heat pump installation in the UK costs between £3,000 and £20,000 after the Boiler Upgrade Scheme grant, which can be up to £9,000 if you’re on oil or LPG. Final costs depend on property size, insulation levels, emitter upgrades and system design quality. At Heat Geek our average install price is £3,000 (after the grant). That's the same as swapping out your gas boiler.
Because every home is different, the only way to get accurate numbers is through a properly modelled design. Heat Geek’s paid Design Consultation provides a full heat loss calculation, system specification and guaranteed performance estimate tailored to your property.
We believe that local, independent installers can be the highest quality installer in the country. They understand your region’s housing stock, climate and regulations – ensuring the best results for your home.
