Most UK homes have an Energy Performance Certificate on the national register. The moment you enter your address, we pull yours and analyse what it says about your property — floor area, energy rating, current heating fuel, property type and age — and turn it into a heat pump cost estimate built for your home, not a UK average.
The heat pump output (kW) a home of your size and fabric typically needs.
With the £7,500 grant already deducted, so you see what you'd actually pay.
Your EPC rating today, its potential, and whether anything needs attention before installing.
What you're running now — gas, oil or LPG, read from your EPC — factored into your estimate.
The same heat pump can be priced thousands apart.
Installers price the same job very differently — how busy they are, how far they travel, which brands they fit and how they size your system all move the number. On a typical £13,000 installation, the gap between two quotes is often four figures.
That's why we do the pricing research for you. We compare installers across your area and match you with the two most competitive vetted MCS installers — each quoting knowing they're being compared, so sharp pricing is built in from the start.
We do the shopping around for you — no hunting for installers or requesting quotes one by one.
Like-for-like comparison — both tailor quotes to your home's exact requirements.
Homeowners save £1,200 on average — versus accepting the first quote they're given.
Four things that set your heat pump price
Every quote is these four variables combined — measured from your home, not the market.
The more heat your home loses, the bigger the system it needs — this sets the baseline.
Lower flow temperatures mean some rooms need bigger radiators — many homes need none at all.
Combi-boiler homes add one; homes with a cylinder usually keep theirs.
Sized from your home's heat loss, not guessed — oversizing wastes money, undersizing costs comfort.
No two homes combine them the same way — your estimate does the maths.
Get my estimateHow the £7,500 grant actually works
The Boiler Upgrade Scheme (BUS) is the government's grant for low-carbon heating in England and Wales — in Scotland, Home Energy Scotland provides the equivalent (see right). If your home is eligible, your MCS-certified installer applies on your behalf as part of the quote — there's no separate form for you to complete. The £7,500 grant is deducted directly from your installer's quote, so you never pay it upfront and claim it back later.
Your estimate checks eligibility — most owner-occupied homes qualify.
Your MCS installer applies for you — in Scotland you apply to Home Energy Scotland first, and we make it straightforward.
You apply to Home Energy Scotland first — before installation, with our help — then your MCS installer takes it from there.
£7,500 comes off your install cost — £9,000 in rural Scotland — nothing to claim back later.
The Boiler Upgrade Scheme covers England and Wales. Scottish homeowners apply to Home Energy Scotland instead: a £7,500 grant (£9,000 in rural areas) plus an optional interest-free loan of up to £7,500. Unlike BUS, you apply yourself before installation — your estimate and installer make the paperwork straightforward.
Home Energy Scotland covers Scotland. In England and Wales the equivalent is the Boiler Upgrade Scheme (BUS): the same £7,500 grant, applied for by your MCS installer as part of the quote and deducted upfront — nothing to claim back later.
What you'll actually save
Heat pump running costs are lowest — and savings biggest — when you're replacing oil, LPG or an older gas boiler. Your exact figure depends on your tariff and your home's fabric — homes coming off electric or new efficient gas boilers save less.

Still unsure what it means for your home? Your instant estimate turns these general answers into your own numbers in about 90 seconds.
Typical UK installations range from about £8,500 to £15,500 before the grant — the national median through the Boiler Upgrade Scheme is around £13,000. After the £7,500 grant, most homeowners pay £4,000–£6,000, with simpler installs from around £1,000. Our instant estimate gives you a transparent figure tailored to your home — in under 90 seconds.
A 3-bed semi typically lands at £10,000–£13,500 installed, and a 4+ bed detached at £12,000–£15,500 — before the grant. With the £7,500 grant applied — BUS in England & Wales, Home Energy Scotland in Scotland — that's from £2,500 and from £4,500 respectively. Radiator and cylinder work are what push a home towards the top of its range.
The Boiler Upgrade Scheme gives eligible homes in England and Wales £7,500 towards an air source heat pump installation — most owner-occupied homes qualify. Your MCS-certified installer applies as part of the quote and deducts it upfront. In Scotland, Home Energy Scotland offers a £7,500 grant (£9,000 in rural areas) plus an optional interest-free loan.
Four home-specific factors: size and insulation, radiator upgrades, hot water cylinder, and system size. They combine differently in every home — which is why two neighbours can get quotes thousands apart, and why your estimate is built from your property's own data rather than a national average.
Homeowners replacing oil, LPG or an older gas boiler save £900–£1,400 a year on average. Savings depend on your tariff and your home's fabric — homes coming off electric or new efficient gas boilers save less. A heat pump delivers 3–4 units of heat per unit of electricity, which is what makes the maths work.
