What’s inside the guide
The UK heat pump market is growing rapidly in 2026, driven by rising gas and oil prices, the Boiler Upgrade Scheme grant and increasing demand for low-carbon heating systems. With £9,000 now available to homes on oil, there’s never been a better time to get a heat pump. But while interest in air source heat pumps is accelerating, installation quality hasn’t always kept pace.
Many homeowners researching heat pump costs, heat pump savings, and whether heat pumps are worth it are being met with confusing information, unrealistic performance claims, and quotes that don’t explain how system design affects running costs.
That’s exactly why this guide exists. It was written to help UK homeowners:
- Avoid common heat pump installation mistakes
- Understand real-world heat pump costs in 2026
- Compare running costs vs gas boilers properly
- Make informed decisions based on performance, not marketing
- Choose properly designed systems that actually deliver the projected savings
Whether you ultimately install with Heat Geek or another installer, you should fully understand how heat pumps work, what affects efficiency, and what determines long-term savings before committing to a system that could cost more than you anticipated in the long run.

FAQs
How much do heat pumps cost in the UK in 2026?
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.
Are heat pumps cheaper to run than gas boilers?
In many cases yes, especially when properly designed and when factoring long-term gas price inflation and your chosen tariff. Running costs depend on efficiency and tariff structure so it's worth looking closely at your best option. Use our calculator to give you an idea of what running costs could look like for you.
Do heat pumps actually save money over time?
Heat pumps can deliver long-term savings, particularly when factoring in rising gas and oil prices, government grants and avoided boiler replacement costs. Payback periods vary by home and depend heavily on system efficiency. Studies such have also confirmed that installing a heat pump in the UK can raise the value of your property by up to 3%.
Is the Boiler Upgrade Scheme still available in 2026?
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 which is rising to £9,000 for homes on oil or LPG. 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.
