Do Heat Pumps Add Property Value? EPC, Buyers and Valuations
One of the most common questions homeowners ask before investing in a heat pump is: will it add value to my home? Published research links better EPC ratings with higher sale prices, and a heat pump can improve an EPC rating. But the detail matters, and not every installation adds the same value. This guide sets out what the evidence suggests and how to present a heat pump when you sell.
The property market has changed dramatically in its attitude toward energy efficiency over the past five years. The 2022 energy crisis was a watershed moment — for the first time, energy costs became a serious consideration in property purchasing decisions. Energy bills, EPC ratings and heating systems are now a bigger part of many buyers' decisions.
This shift is good news for heat pump owners. But the value added depends on several factors: the quality of the installation, the resulting EPC improvement, and the property's target market. Not all heat pump installations add equal value — and understanding what buyers actually care about helps you maximise the return.

The Evidence: Do Heat Pumps Add Value?
Several sources of evidence point to a value premium for energy-efficient homes:
DESNZ Research
The Department for Energy Security and Net Zero has published research showing that homes rated EPC A-B sell for 5-14% more than equivalent homes rated D-G. The premium is highest in areas where energy costs are a greater proportion of household income.
Rightmove Data
Rightmove's Energy Efficiency Report found that searches for "energy efficient" properties increased by over 300% between 2021 and 2025. Properties marketed with energy efficiency features (including heat pumps) received more enquiries and sold faster than equivalent properties without them.
Academic Research
Academic studies from the London School of Economics and UCL have found consistent price premiums for energy-efficient homes across the UK market, with the premium growing over time as energy costs increase and policy requirements tighten.

The EPC Rating Premium
A heat pump installation typically improves a property's EPC by 1-2 bands. For example:
| Scenario | Before Heat Pump | After Heat Pump | Estimated Value Impact (£300k home) |
|---|---|---|---|
| Gas boiler → ASHP, decent insulation | EPC D (60) | EPC B (82) | +£15,000-£25,000 (5-8%) |
| Oil boiler → ASHP, good insulation | EPC E (45) | EPC C (72) | +£10,000-£18,000 (3-6%) |
| Gas boiler → ASHP, poor insulation | EPC D (55) | EPC C (68) | +£6,000-£12,000 (2-4%) |
| Gas boiler → ASHP + solar + insulation | EPC D (58) | EPC A (92) | +£25,000-£40,000 (8-14%) |
Illustrative estimates applying published EPC price-premium research to example scenarios; not a valuation. Actual impacts vary by property, location, and market conditions.
The greatest value increase comes from combining a heat pump with insulation improvements and solar panels — pushing the EPC from D or below to A or B. This comprehensive approach delivers the highest premium because it signals a truly energy-efficient home with low running costs.
How Buyer Attitudes Are Changing
For some buyers, an existing heat pump is a selling point: a gas boiler will eventually need replacing, and a home where the heating has already been switched avoids that future decision.
Different buyer groups are likely to value a heat pump differently:
- Under 35s: Most positive. Often environmentally motivated and aware of future regulations. View heat pumps as a modern, future-proof feature
- 35-55: Financially motivated. Focus on energy bill savings and avoided future costs. Want evidence of running costs
- Over 55: More cautious. May be unfamiliar with the technology. Some prefer the familiarity of gas. However, attitudes are shifting as more people encounter heat pumps in friends' and neighbours' homes
Regional Variation in the Premium
In rural, off-gas-grid areas where homes use oil or LPG, which are not price-capped, lower running costs can make a heat pump a stronger selling point. In on-gas-grid areas, any premium is more likely to come from the EPC rating and future-proofing.
| Location Type | Estimated Premium | Main Driver |
|---|---|---|
| Rural (off-gas-grid) | High (5-10%) | Direct fuel cost savings vs oil/LPG |
| London and South East | High (5-8%) | EPC awareness, environmental values |
| Suburbs (on-gas-grid) | Medium (3-5%) | Future-proofing, EPC improvement |
| Northern cities | Medium (2-4%) | Growing awareness, cost savings |
| Scotland | High (5-8%) | Strong grant support, climate awareness |
Presenting a Heat Pump When You Sell
Three points are worth making clear to buyers and agents: the EPC rating, realistic annual running costs, and the fact that the heating system is relatively new.
Practical steps to make the most of a heat pump when you sell:
- Get an updated EPC that reflects the heat pump installation
- Provide 12 months of energy bill data showing running costs
- Keep the MCS certificate and warranty documentation accessible
- Highlight the BUS grant history — the buyer inherits a subsidised system
- Ensure the outdoor unit is tidy and well-screened

How to Maximise the Value Add
Not every heat pump installation adds the same value. Here is how to maximise the return:
- Improve insulation first — a heat pump in a well-insulated home delivers the biggest EPC improvement
- Add solar panels — solar panels combined with a heat pump can push the EPC to A, commanding the highest premium
- Use a quality installer — proper documentation and MCS certification reassure buyers and surveyors
- Keep running cost records — real data is more persuasive than estimates
- Maintain the system — annual service records show the system has been cared for
Impact on the Rental Market
For landlords, the value proposition is even clearer. Minimum EPC requirements for rental properties are being tightened — currently EPC E, with proposals for EPC C by 2028-2030. A heat pump installation future-proofs a rental property against these requirements while also improving tenant satisfaction and reducing void periods.
The BUS grant is available to landlords, making the investment case compelling. Our cost guide covers the financial analysis for both owner-occupiers and landlords.
Future Outlook: The 2035 Factor
As the 2035 date approaches, the property market impact of heating systems will intensify. Homes with heat pumps will be viewed as "done" — ready for the future. Homes with gas boilers will carry an implicit liability — the cost of an eventual, compulsory heating system change. This dynamic is expected to widen the value gap significantly over the next decade.
Frequently Asked Questions
Do heat pumps increase property value in the UK?
Yes. Research shows homes with EPC A-B sell for 5-14% more. A heat pump typically improves the EPC by 1-2 bands, contributing to this premium.
How much value does a heat pump add to a house?
The EPC improvement alone can add 3-8% to property value — potentially £8,000-£25,000 on a £300,000 home.
Do buyers want homes with heat pumps?
Increasingly yes. Energy efficiency is now a top-5 buyer priority. Younger buyers are most positive, but attitudes are shifting across all age groups.
Can a heat pump make a property harder to sell?
Only if poorly installed or documented. A well-installed system with good records is overwhelmingly positive for resale.
Does the EPC rating affect property value?
Significantly. Properties rated A-B sell for 5-14% more than equivalent D-G rated properties. This premium is expected to grow as regulations tighten.

Property Value in the Energy Transition
The relationship between energy efficiency and property value is strengthening as the UK moves toward net zero. Homes with heat pumps, good insulation, and solar panels command growing premiums in the market. The Boiler Upgrade Scheme makes the initial investment more accessible, while the EPC improvement and future-proofing add lasting value. As the 2035 gas boiler phase-out approaches, this value differential will only widen, making early adoption a smart financial as well as environmental decision.
