UK heat pump suitability
Find out if your home is ready for a heat pump
We'll tell you whether a heat pump suits your home, what it would roughly cost after the grant, and match you with one vetted local installer. If your home isn't ready yet, we'll say that too.

-
Suitability verdict
Full Pass, Conditional Pass, or Not Yet. One plain answer for your house, not a score out of ten.
-
Estimated net cost
What the install will cost after the £7,500 BUS grant, based on your property and current heating.
-
Estimated annual savings
Roughly what you'd save each year vs. your current heating. Real UK tariffs, not manufacturer lab figures.
-
What needs to happen first
If insulation, radiator upgrades, or anything else needs to come first, you see it here with a rough cost.
Why not just use the GOV.UK checker?
-
One of three
Built on your actual home, not averages.
We start from your home's EPC record, which is the same data the BUS grant is checked against. The verdict reflects your house, not a national average that doesn't.
-
Two of three
One introduction, only if you say yes.
When your home qualifies and you want to go ahead, you're introduced to one vetted MCS-certified installer. Most homeowner quote sites share your postcode with a panel of three. HeatPass doesn't.
-
Three of three
Honest when it's not the right fit.
If your home needs insulation or radiator work first, you get an Improvement Plan and nobody gets your details. Come back when the picture has changed, or let us email you when it does.

The honest part
When a heat pump isn't the right answer yet.
A heat pump isn't right for every UK home. A solid-wall Victorian terrace with single glazing usually needs the insulation work to come first, or the pump runs hot and the savings don't cover the outlay. A flat with no outdoor space has the opposite problem: nowhere sensible to put the unit. And if you rent, the call isn't fully yours to make anyway.
I check all of this for your house. You get a list of what would change the picture, roughly what each step would cost, and when the answer is "not right yet," no installer sees your details.
Nothing happens on a 'Not Yet'. You keep the Improvement Plan, come back when the picture has changed, and nobody contacts you in between. Other quote sites pass your postcode to three or four installers the minute you hit submit. I look at your house first, and only make the one introduction when your home is ready and you've asked me to.
Common questions
Everything homeowners tend to ask.
-
Is this free?
Yes. HeatPass is free for homeowners. Installers pay us when we introduce them to a suitable home.
-
How accurate is the verdict?
The verdict is built from your property's official EPC data plus a short set of questions only you can answer. It's a strong first read, not a replacement for a site survey. If your home qualifies, the installer confirms details in person before quoting.
-
Where does my data come from?
We use the UK government's Energy Performance Certificate register, which holds records for about 28 million homes. If your home doesn't have an EPC, you can still go through the questions and we'll ask a few extra things.
-
What happens if my home isn't ready?
You get a Conditional Pass or Not Yet verdict with an Improvement Plan. It lists what would help most, roughly what each step would cost, and what it would change. No installer gets your details in this case. Come back and run the check again any time the picture has changed.
-
Who are the installers? How are they vetted?
Only MCS-certified installers can work with BUS grants, and only MCS-certified installers can use HeatPass. On top of MCS we check Companies House history, postcode coverage, install volume, references, and customer feedback over time.
-
Will my details be shared with multiple companies?
No. Even when your home qualifies, nothing moves until you confirm you'd like an introduction. If you say yes, your details go to a single MCS-certified installer covering your postcode. Never to a panel of three. If the match doesn't feel right you tell us and we step back.
-
Is HeatPass affiliated with the government or MCS?
No. We're independent. We use the government's public EPC register and we only work with MCS-certified installers, but we're not part of either body.
-
What does the BUS grant cover?
The £7,500 Boiler Upgrade Scheme grant is paid by the government towards the cost of installing an eligible heat pump in an owner-occupied home. Your MCS-certified installer applies for it on your behalf and takes it off your quote. We'll show you whether your home qualifies and what's left to pay.
