Does a Heat Pump Add Value to Your House in the UK?
Heat pumps are not yet a headline value-add in the UK the way an extra bedroom is. Direct uplift is typically 0–3%. What is changing is the indirect value: a heat pump usually lifts your EPC band, opens up green mortgage rates for the buyer, and removes a retrofit job they would otherwise have to price in.
Heat pumps and house value — 2026 UK at a glance
- Direct uplift: typically 0–3% — the market is still pricing this in.
- EPC effect: commonly a one-band improvement, sometimes two on an oil or electric-heated home.
- Install cost: £7,000–£14,000 for an air source heat pump before grant.
- Boiler Upgrade Scheme: £7,500 grant available, cutting the net cost substantially.
- Biggest gains: homes currently on oil, LPG or direct electric heating — not efficient mains gas.
Bottom line: a heat pump is a running-cost and future-proofing decision that happens to help your EPC. Treat any resale uplift as a bonus, and take the grant — that is where the real arithmetic changes.
Heat pump cost vs value in 2026
Net costs assume the £7,500 Boiler Upgrade Scheme grant and an MCS-certified installer. Homes needing radiator upgrades or additional insulation to run efficiently will sit at the top of each band.
Where a heat pump genuinely helps your sale
- Off-gas-grid homes — replacing oil or LPG produces the biggest running-cost and EPC improvement, and buyers notice.
- Homes stuck at EPC D or E — crossing into C unlocks green mortgage products and reassures buyers on future regulation.
- Rental properties — minimum energy efficiency standards make a poor EPC a compliance liability, not just a marketing issue.
- Already well-insulated homes — a heat pump in a leaky house gives disappointing bills and a weak story; insulate first.
- Not compelling on an efficient mains-gas home with a recent boiler, where the payback case is currently thin.
Tip: insulate before you install. A heat pump sized for a poorly insulated house is bigger, dearer and more expensive to run — and it is the running cost, not the badge, that persuades a buyer.

Frequently asked questions
Directly, only modestly - typically 0-3%. The more meaningful effect is indirect: a heat pump usually improves your EPC band, opens up green mortgage products for the buyer, and removes a retrofit cost they would otherwise price into their offer.
GBP 7,000-14,000 before grant for a typical family home, including radiator upgrades and a hot water cylinder where needed. The GBP 7,500 Boiler Upgrade Scheme grant brings the net cost down substantially.
Usually yes, commonly by one band and sometimes two if you are replacing oil, LPG or direct electric heating. Replacing an efficient modern gas boiler produces a smaller gain.
Yes. The Boiler Upgrade Scheme continues to offer GBP 7,500 towards an air source or ground source heat pump in England and Wales, applied for by your MCS-certified installer rather than by you directly. Check current eligibility on gov.uk before committing.
Some will, particularly off-gas-grid buyers and those seeking a green mortgage. Most buyers today value the lower running costs and the fact the work is already done, rather than paying an explicit premium for the technology itself.
Yes. Insulation reduces the heat pump size you need, cuts both the install cost and the running cost, and produces a better EPC. A heat pump in a poorly insulated home delivers disappointing bills, which undermines the value story entirely.

Methodology: Value ranges are indicative estimates compiled from published UK house-price indices, surveyor guidance and agent-reported sale data for Q3 2026, expressed as a percentage of typical property value. Actual uplift depends heavily on local market, property type and build quality - always take advice from a local valuer before budgeting on a resale figure. Last fact-checked: .
