How It Actually Works
No magic. Just physics.
Heat pumps don't *generate* heat — they *move* it. They take warmth out of the outside air and concentrate it indoors, the way a fridge does the opposite. The result is 3–4× more heat out than electricity in.
Capture
A fan draws outside air across a refrigerant coil — even at 0°C the air still holds usable heat. The refrigerant absorbs it and turns to vapour.
Compress
A compressor squeezes the vapour, raising its temperature dramatically. This is the only stage that uses meaningful electricity.
Transfer
The hot refrigerant passes through a heat exchanger, transferring heat into your central heating water and hot water cylinder.
Repeat
For every 1 kWh of electricity used, a modern heat pump delivers 3–4 kWh of heat. That's the whole reason it's greener than gas.
The Honest Bit
Not every home is right for one.
Most installers will sell a heat pump to anyone who'll buy one. We won't. Here's the rough qualifier — if you're a "no" on the right-hand side, we'll usually say so on the phone before booking a survey.
Real Numbers
What you'd save vs staying on gas.
Modelled on a typical 3-bed semi using 12,000 kWh/year of heat. Assumes current price cap, 3.5 SCOP heat pump, modest annual energy inflation. Your numbers depend on your home — we model yours properly at survey.
Indicative only. Actual savings depend on your home, insulation, electricity tariff and usage patterns. We can run a personalised model at survey.
From Eligibility to Sign-Off
Five steps. We handle the lot.
01
Free eligibility call
We ask about your property, insulation, hot water demand and outdoor space. If a heat pump isn't right for you, we say so on the phone — no survey needed.
02
On-site MCS survey
Full heat-loss calculation, room-by-room. Existing radiator schedule reviewed and resized if needed. Outdoor unit position agreed with you. Detailed written quote within a week.
03
Grant application
You stay hands-off. We submit the Boiler Upgrade Scheme application, deal with Ofgem, and apply the £7,500 directly to your invoice. You never see the paperwork.
04
Installation
Most installs take 3–5 days. Outdoor unit, indoor controls, cylinder, radiator changes if needed, and full pipework. Floors and carpets protected throughout.
05
Commission & sign-off
System balanced, controls set, and a full handover walkthrough. MCS certificate issued — required for the grant and any future warranty claims.
Indicative Pricing · After Grant
Three property sizes. Real ranges.
Heat pump pricing varies too much by property to quote on a page. Every install is survey-led — we measure heat loss, size the unit, plan radiator changes and confirm a fixed price in writing before any work starts. The Boiler Upgrade Scheme £7,500 grant is applied directly to your invoice.

"Heat pump rescue"
We have nothing but praise for Adam & Danny — they did a great job sorting out our heat pump issues (which was fitted by another company). Just wish we had known of them when ours was fitted a couple of years previously. Nothing was a problem for them, they were very attentive with everything they did at our home. We cannot thank them enough — what a great couple of individuals and great company they are.

"Put my mum at ease"
Well what can I say — absolutely brilliant service. I would highly recommend this company. They came and fitted a new boiler system for my 85-year-old mother-in-law who's agoraphobic. They're extremely lovely lads and really put her at ease — nothing was too much trouble. They arrived when they said they would (which is a bonus nowadays) and kept me informed throughout. It wasn't an easy job but their work was 100% and they left the place nice and tidy afterwards. I honestly can't rate this company high enough — 10/10 lads, thank you for all your hard work.

"Diagnosed clearly"
Had problems with getting hot water for a few weeks and Danny came out straight away and diagnosed the problem, which required replacement of the heat exchange plate. They explained clearly what the issue was and what was needed to fix it. Part was ordered and replaced in a couple of days. All work was undertaken without any mess or disruption — I would use them again and recommend them without hesitation.

"Rectified — no problem"
Had the lads come to lay a new gas pipe for a kitchen refurb along with relocating the pipework for 2 new radiators. Then recalled them to move the gas pipe slightly as my measurements were off — which they rectified, no problem. Very professional. Would highly recommend.
