In 2026, a typical air source heat pump installation in the UK costs between £3,000 and £20,000 after the £7,500 Boiler Upgrade Scheme grant. 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 (£250) provides a full heat loss calculation, system specification and guaranteed performance estimate tailored to your property.

Heat pumps can be cheaper to run than gas boilers when they are correctly designed and operate at low flow temperatures. Running costs depend on electricity tariffs, gas prices, home insulation and system efficiency.

A properly designed system makes the difference between strong savings and disappointing performance. During a Heat Geek Design Consultation, your home’s real heat demand is modelled to predict realistic running costs and long-term savings.

Heat pumps can deliver long-term savings, particularly when factoring in rising gas prices, government grants and avoided boiler replacement costs. Payback periods vary by home and depend heavily on system efficiency. Studies such as this one have also confirmed that installing a heat pump in the UK can raise the value of your property by up to 3%.

Yes. The UK government’s Boiler Upgrade Scheme currently offers a £7,500 grant toward eligible air source heat pump installations in England and Wales. The grant must be applied for through an approved installer and eligibility rules apply. In Scotland the HES Grant can provide even more funding. All details are in the 2026 Heat Pump Guide.
