27 August 2026Great with exception of the initially damaged heat pump and confusion regarding having that removed

Luke Riggall★★★★★
26 August 2026The website and communication is spot on. Incredibly useful having all the digital paperwork at the end of the process. I would say that the efficiency guarantee is a huge factor in selecting heatgeek, however without an open energy monitor setup, we are reliant on the manufacturers own data which I understand is far from accurate. Which in hindsight leads me to confusion as to how the guarantee is meaningful without accurate efficiency data. I’d like to hear back from you regarding this, and we expect to achieve over 5SCOP from our system as everything has been engineered for maximum efficiency.

25 August 2026Perfect service from start to finish. I tried other heat pump suppliers who said our house was not suitable, but the system they installed was well, and it was done with minimal disruption and no need for new pipework other than around where the old gas boiler was removed and the new controls were fitted to our existing hot water cylinder..

23 August 2026The communication and documentation could not be faulted. As an aside the many You Tube videos were of considerable value in understanding the system and what is involved in an installation.

22 August 2026The web and emails have been very good when you get your head around them. I am disappointed that there has been a second heat pump clogging up my garden for the past three weeks, with no sign of it ever being collected.

How much can you save with a heat pump?
More than you might think
85% of heat pump households pay the same or less to heat their home than they would with gas. The Boiler Upgrade Scheme is available right now meaning you can benefit from a grant of up to £9,000.
The biggest factor in whether those numbers work for you isn't the technology, it's the installation. A well-designed system delivers. A poorly designed one doesn't. That's why it matters who fits it.
Got solar or batteries? We've built a calculator that gives you a real estimate of savings based on your exact set up.
You go somewhere and you say that you're a Heat Geek. You've got the logo on your shirt and people recognise this. You know this is a real good brand to be part of.

Having a Heat Pump Just Got Even Cheaper
Heat pumps already cost less to run than a gas boiler, and a smart tariff cuts the bill further. From 1 October, a VAT cut on electricity stacks a third saving on top, one that gas boilers don't get.

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.
How quiet is the aroTHERM?
From 29 dB, roughly as quiet as a whisper. Well within UK planning noise limits, even close to neighbouring properties.
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.
What about Daikin, Mitsubishi, or Samsung?
Reputable manufacturers, but we specialise in Vaillant. Deep expertise in one platform means better designs, better installations, and better outcomes than trying to be generalists.
