The short answer just changed. Until recently a heat pump install cost £12–15k, which put it out of reach for most families. Through Heat Geek's ZeroDisrupt system we can now install a heat pump in Staffordshire from around £3,000, about the same price as a new gas boiler, with the £7,500 Boiler Upgrade Scheme grant already deducted. Here's how that's possible, what's included, and what moves the price for your home.
Heat pump vs new gas boiler: the 2026 price comparison
The honest way to think about it is against the thing you'd otherwise buy, another gas boiler:
| Option | Typical installed price | What happens to your bills |
|---|---|---|
| New gas boiler | £2,000–£4,000 | Locked into gas prices for 10–15 years |
| ZeroDisrupt heat pump (after £7,500 grant) | from ~£3,000 | Lower running costs, month after month |
| Heat pump the old way (pre-ZeroDisrupt) | £12,000–£15,000 | Same savings, but few could afford the install |
The ZeroDisrupt price includes the heat pump, hot water cylinder, controls, installation labour, commissioning, MCS certification and the grant application. Larger homes or ones needing radiator upgrades cost more than the starting price, your instant estimate gives you your own number in about two minutes.
How is boiler-price possible without cutting corners? By cutting waste: ZeroDisrupt designs are generated from data on thousands of real UK homes, so there's no over-sized kit, no unnecessary upgrades and no padded quotes. Read the full story on our ZeroDisrupt page.
What actually moves the price?
1. The size of the system. Bigger homes lose more heat and need more kilowatts, a bigger cylinder and sometimes larger pipework. This is the single biggest factor, and it's why we won't quote a fixed price without measuring your home first.
2. Radiator upgrades. Heat pumps run cooler than boilers, so each radiator needs enough surface area for its room. In a typical Staffordshire semi we change two or three radiators (£150–£300 each, fitted); many homes need none; a few older properties need more. The survey tells you exactly, radiator by radiator, before you commit.
3. Cylinder location and pipework. If you have an airing cupboard (or an old cylinder to replace), it's straightforward. Combi-boiler homes need space finding for a cylinder, usually the airing cupboard, loft or garage, and that can add pipework time.
4. Your old fuel. Replacing oil or LPG tends to be slightly simpler (no gas to cap) and delivers the biggest running-cost savings; replacing a gas combi is the most involved because of the cylinder point above.
The £7,500 grant, the bit that changes everything
The Boiler Upgrade Scheme pays £7,500 towards an air source heat pump when you're replacing a fossil-fuel boiler. It's not a rebate you claim afterwards: as your MCS-certified installer, we apply for it and deduct it from your quote, so the prices you see from us are the prices you pay. Most owner-occupied homes qualify. Full grant guide here.
Beware quotes without a survey
Any installer who gives you a fixed heat pump price from a phone call is guessing, and guessed systems are where the horror stories come from (oversized units short-cycling, undersized ones limping through January). A room-by-room heat loss survey takes 45 minutes, it's free, and it's the difference between a heat pump that delivers its promised efficiency and one that doesn't. That's not our sales angle; it's the industry's hardest-learned lesson.
