How Much Does a Heat Pump Actually Cost?
Enter your details and see your real cost, savings, and payback period. Our estimates are built on real data from thousands of installed systems. No commitment.
Online estimates are misleading
They don't know your home
A terraced house in Bristol and a detached farmhouse in Yorkshire need completely different systems.
They're not based on real installs
Most calculators use industry averages. Heat Geek's estimates are built on design and performance data from thousands of real installations — every home we scan and install in makes the next estimate more accurate.
They don't show running costs
The installation cost is half the picture. Total cost of ownership over 15-20 years is what matters.

FAQs
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.
How long does it take for a heat pump to pay back?
Payback time varies by property and usage. Often you can trade off upfront install cost and monthly savings so that you get a result that matches your financial needs. Use our calculator to give you an idea of what running costs could look like for you.
Do heat pumps increase house value?
Studies have confirmed that installing a heat pump in the UK can raise the value of your property by up to 3%.
What affects heat pump savings the most?
System design efficiency, insulation level, electricity tariff and whether gas standing charges are removed are some of the biggest factors in how much your heat pump can save you. But, we'd always say the most important thing is to have the right installer so your system is designed and installed well.
