What could have been a daunting upgrade from a gas boiler to a heat pump heating system was made almost completely pain free. I felt supported and, importantly, listened to at every stage from initial home survey, through to installation and commissioning. Communication with both our installer and Heat Geek was excellent with the entire project completed to the highest standard on time and on budget. How often can you say that?

Using the Heat Geek service made my transition to a heat pump easy and straightforward. They took care of everything, from applying for the available grants to surveying my existing heating system and arranging the installation, all within just a couple of weeks. Gary and his son Harry were outstanding from start to finish. They were always punctual, polite, friendly, and their knowledge and professionalism inspired confidence from day one. They took great pride in their work, leaving everything clean and tidy at the end of each day, and were always happy to accommodate any requests or preferences I had throughout the installation. The work was completed on schedule to an exceptionally high standard, and the attention to detail was excellent. I couldn't be happier with the result and would highly recommend both Heat Geek and Gary and Harry to anyone considering a heat pump installation.

Always at the end of an email with exactly what I required. The only downside is that there isn’t someone to speak to but, in reality, it isn’t required once you have your local heat geek assigned to you. There is a wealth of information available on the website for anyone thinking of making what we now realise is the obvious choice in low carbon technology. Would be nice to have more information available about the DNO process as that took longer than any of the heat geek processes combined.

We exchanged several emails to refine the system design, which was great. Darren made particular efforts to enable the system to proceed by considering a location physically away from our house due to nearby windows and doors, and fitting the hot water tank into a tight space. Darren and his colleagues turned up on time every day and kept disruption to a minimum, enabling me to continue to work from home during the installation.

In a nutshell absolutely perfect from start to finish. They came when they said they were coming, a three man team that did not stop for 3.5 days solid. The work carried out was to the highest level, I was walked through the installation live step by step and what was to be expected once completed. Every day after work was comple the house was tidied up and left clean. On completion I was taken through the controls and was told that they was just at the end of the phone so do not hesitate to call with anything I needed to know. I was totally happy with the Install, the installation team and i know I have made the best chose in choosing a heat geek Installer future flow heating Ltd.

Brilliant experience from initial survey, through to final commissioning. Fantastic team from JLM in Coventry who battled with extreme heatwave temperatures to complete a very technically competent and professional install, the entire team was a pleasure to deal with. Highly recommended

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.

Why choose a local installer instead of a national firm?

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.

Is there a Heat Geek available in my area?

Yes, we cover nearly all of the UK, from Brighton to Aberdeen – check your address for an estimate and we’ll match you with a local installer.
