How much does a heat pump cost?
The quickest way to find out how much a heat pump will cost for you is to get a quote. We ask for a few quick details, and use this together with other clever data sources, such as your home’s Energy Performance Certificate (EPC) and energy usage, to calculate your estimated cost. after your home survey, we'll be able to provide your final fixed price.
For the best indication of how much a heat pump will cost for you…
We’re the largest installer of heat pumps in the UK and we’re obsessed with making heat pumps more affordable. We’ve invested £50 million to drive the rollout of heat pumps and push down costs (including building our own).
The result is that we’re able to offer customers cheaper prices than many other heat pump installers - most of our quotes are lower than the UK’s average heat pump cost of £5,049 (Jan '25 gov' data), including the BUS grant. We also offer a broader range of services - planning support, EPC, asbestos testing, aftercare, etc. - than most installers.
Our heat pumps start at £4,300 for a standard install (including the BUS grant), and for larger or less insulated homes, switching to a heat pump can be a bit more expensive.
Heat pumps pair perfectly with smart tariffs like Cosy Octopus, so this one-time cost can unlock hundreds of pounds in savings every year. And going forward, replacing your heat pump will be as easy as replacing your boiler. Plus, heat pumps last up to 20 years, while gas boilers only last up to 15 years.
What does my heat pump include?
We do an in-person survey for every heat pump order to ensure everything is correct and confirm exactly what’s required. After the survey, we’ll update the quote to include any changes and explain them to you.
- An air source heat pump - either a Octopus Cosy or a Daikin heat pump. This will be expertly configured to your home to either a Cosy Turbo or Eco spec.
- Heat pump-compatible water cylinder
- Any necessary radiators and electrical work to meet our design standard
- Standard installation pipework
- Labour and workmanship
- Heat pump manufacturers’ warranty (varies depending on the manufacturer)
- Octopus Cosy heat pump: 8-year warranty
- Other brands: 5-year warranty
- 2-year labour & workmanship warranty
- 2-year warranty on all other parts included in the installation
- Dedicated heat pump “concierge” to help with your installation, plus:
- Help from our planning gurus to help with any planning applications
- Free asbestos testing and an up-to-date EPC if required
- Hassle-free Boiler Upgrade Scheme (BUS) grant application & redemption (we do it all!)
Our installation includes all radiator changes required to meet your heat pump design, which is to achieve a minimum Seasonal Coefficient of Performance (SCOP) of 3.0. This exceeds the Ofgem requirements to redeem the Boiler Upgrade Scheme (BUS) grant.
There should be no surprises during the installation - the price you pay will be the price in the installation agreement. The only exception is that if we discover a repipe is necessary at installation. (We do everything we possibly can to spot a repipe before we get to that point but it does happen!)
