What a fair 2026 heat pump quote includes
A proper quote is itemised, not a single lump sum. Line by line, you should be able to see:
- The heat pump unit — make, model and output (kW), ideally an R290 unit.
- Hot water cylinder — correctly sized for your household, not a token 150L.
- Emitters — any radiator upgrades or underfloor heating, itemised room by room.
- Labour — by the installer’s own engineers, not vague “fitting”.
- Controls — weather compensation and smart controls.
- Commissioning — setting up and balancing the system so it runs efficiently.
If a quote cannot show you these lines, it is not a design — it is a guess.
Typical price ranges (indicative)
These are indicative 2026 ranges before the grant — your actual price depends on your property and heat demand:
- Small / well-insulated home (1–2 bed): roughly £8,000–£11,000
- Average 3-bed semi: roughly £10,000–£14,000
- Larger / older detached: roughly £14,000–£20,000+
The £7,500 Boiler Upgrade Scheme grant comes off these figures, and heat pump installations carry 0% VAT. A typical 3-bed therefore often lands at a few thousand pounds net. Treat any figure here as a starting point, not a promise — a real price comes from a survey.
Red flags in cheap quotes
A suspiciously cheap quote usually hides one of these:
- An undersized unit — cheaper upfront, but it will struggle on cold days and run inefficiently.
- No room-by-room heat-loss survey — the system has effectively been guessed.
- No MCS certification — which means no £7,500 grant and no consumer protection.
- Subcontracted labour — nobody owns the quality of the finished job.
- A token cylinder — undersized hot water storage that leaves you short.
A low headline price that misses the grant and underperforms for 20 years is the most expensive option of all.

How the £7,500 grant is applied to your quote
The £7,500 Boiler Upgrade Scheme (BUS) grant is deducted from your invoice by your MCS-certified installer — you never have to find it upfront or claim it back. We apply for the voucher on your behalf and net it off the final bill.
Eligible off-gas-grid homes (oil, LPG or electric heating) can claim an enhanced £9,000 grant between 21 July 2026 and 31 March 2027. A genuine quote should state clearly which grant it assumes and show the net figure after it.

Comparing quotes is stressful because they are rarely like-for-like. We will review a competitor quote for free and tell you honestly whether it looks fair — the unit sizing, the cylinder, the emitter plan, whether the grant has been applied correctly, and whether anything important is missing.
There is no obligation. Even if you do not choose us, you will walk away understanding exactly what you are being asked to pay for.
Red Flags and Fair Price Ranges
A fair heat pump quote is not just about the headline number — it is about what the number includes. Sense-check any quote against these fair 2026 ranges (after the £7,500 grant and 0% VAT): roughly £4,000 for a small well-insulated home, £5,000–£6,000 for a typical three-bed semi, and £7,000–£8,000+ for a larger detached.
Red flags that should make you pause:
- No heat-loss survey. A price given over the phone or from a floor-area guess is a gamble — proper quotes follow a room-by-room survey.
- A quoted flow temperature of 55–60°C. That signals a “rip-and-replace” job that will run expensively; good design targets 35–45°C.
- No mention of the cylinder, radiator assessment or controls. These materially affect performance and should be itemised.
- The grant not shown as deducted, or MCS not confirmed. No MCS means no grant.
- A price far below the ranges above. The saving is almost always coming out of the design — and you pay it back every winter.
A fair quote shows the survey-based design, the specific unit and cylinder, any radiator changes, the grant deducted at source, and a fixed price. If a quote is missing those, ask — or get a second opinion before you sign.
Frequently asked questions
As an indicative guide, an average 3-bed semi is often £10,000–£14,000 before the grant, with smaller homes lower and large or older properties higher. The £7,500 BUS grant and 0% VAT then reduce the net figure significantly. A survey gives the real number.
Usually because it is not comparing like-for-like: a smaller unit, an undersized cylinder, no proper heat-loss survey, subcontracted labour, or the grant/VAT handled differently. Always compare the itemised detail, not just the headline.
Yes. A fair quote follows a room-by-room heat-loss survey. Anything based purely on floor area or bedroom count is a guess and often leads to an over- or under-sized system.
It should clearly show both the gross price and the net price after the £7,500 grant, and state whether the enhanced £9,000 off-gas-grid grant applies. If it is unclear, ask.
Yes — we offer a free, no-obligation sense-check. Send us the quote and we will tell you honestly whether the sizing, cylinder, emitters and grant treatment look fair.
