An air source heat pump can add value to your house by improving its Energy Performance Certificate (EPC) rating, lowering running costs and making it more appealing to buyers and tenants who want a modern, low carbon home. S
o, does an air source heat pump add value to your house in pounds and pence? In most cases, yes, although the amount depends on your property, how well the system is installed and how energy efficient the rest of the home is.
We are Guscott Heating, and we install air source heat pumps for homeowners and landlords across Kent and the South East. Many of our customers ask whether a heat pump is a smart investment for when they come to sell or let. This guide explains exactly how a heat pump affects property value, what the research says, and how to make sure your installation pays you back.
Can an Air Source Heat Pump Increase the Value of Your Home in Kent?
Yes. An air source heat pump can increase the value of your home in Kent because it ticks the boxes today’s buyers care about most: lower energy bills, a better EPC rating and a heating system that is ready for the future. A heat pump on its own will not transform the price of a house, but it adds value in four clear ways.
- A higher EPC rating. Homes with better energy ratings tend to sell for more, and a heat pump is one of the biggest single upgrades you can make to that rating.
- Lower running costs. Buyers now look closely at energy bills, and a well installed heat pump can heat a home for less than oil, LPG or electric heaters, and often for a similar cost to gas.
- Future proofing. The government’s long term plan is to move UK homes away from fossil fuel heating. A home that has already made the switch saves the next owner the cost and hassle.
- Wider appeal. A growing number of buyers and tenants actively look for greener, cheaper to run homes.
The value a heat pump adds is greatest when it is part of a well insulated, properly designed system. A poorly sized or badly installed system can do the opposite, which is why who you choose to install it matters so much.
Thinking about adding value with a heat pump? Guscott Heating provides air source heat pump installation across Kent and the wider South East of England. We will survey your home, explain how a heat pump could improve your EPC and running costs, and give you a clear price with the £7,500 Boiler Upgrade Scheme grant already taken off.

How Does an Air Source Heat Pump Affect Your EPC Rating?
An air source heat pump affects your EPC rating by changing how your home’s heating and hot water are scored, which usually pushes the rating up, sometimes by one band and sometimes by two or more. The size of the jump depends mainly on what you are replacing.
An Energy Performance Certificate rates a home from A (most efficient) to G (least efficient). It is required whenever a home is sold or let in England and Wales, and it must be shown on property listings, so buyers and tenants see it straight away.
The current EPC calculation leans heavily on estimated running costs and carbon emissions, so the type of heating you have makes a big difference to the score.
Typical EPC Impact by Existing Heating System
| Heating you are replacing | Typical effect of an air source heat pump on EPC |
| Electric storage or panel heaters | Often a large improvement, commonly two bands or more |
| Oil or LPG boiler | Usually a clear improvement, often one to two bands |
| Older, inefficient gas boiler | Often a modest improvement, sometimes one band |
| Modern condensing gas boiler | A small improvement or, in some homes, little change |
These are broad patterns from experience rather than guarantees. Every home is assessed on its own insulation, windows, size and layout as well as its heating.
Why Off Gas Homes Gain the Most
Off gas homes gain the most because oil, LPG and electric heaters score poorly on cost and carbon. Many rural properties across the Kent Weald, the North Downs and Romney Marsh fall into this group, including homes around Cranbrook, Tenterden, Wye and New Romney. For these households, a heat pump can be the single most effective way to lift an EPC rating.
Upcoming Changes to EPCs
The government has set out plans to reform EPCs so they give a fuller picture of a home’s energy performance, including clearer information about the heating system and its carbon impact.
Changes like this are expected to show the benefit of low carbon heating more clearly than today’s certificates. Exact timings can shift, so we always check the latest position when advising customers.
Getting a New EPC After Installation
An EPC stays valid for 10 years, so the one on file for your home may not show your new heat pump. If you plan to sell or let, it is worth booking a fresh assessment once the system is in, so buyers and tenants see the improved rating rather than the old one.
How Much Value Can an Air Source Heat Pump Add to a Kent Property?
An air source heat pump can add anything from a few thousand pounds to tens of thousands to a Kent property, depending on how far it lifts the EPC rating and how energy efficient the home becomes overall. There is no fixed figure for a heat pump on its own, but research into EPC ratings and house prices gives a useful guide.
What the Research Says
Several major UK studies have found a clear link between energy efficiency and house prices:
- Nationwide Building Society found that homes in England and Wales rated EPC A or B sold for around 1.7% more than similar homes rated D, while homes rated F or G sold for around 3.5% less.
- Rightmove’s Greener Homes research estimated that improving a home from EPC F to C could raise its asking price by around 15% on average.
- Government commissioned research into EPCs has also found that homes with higher ratings tend to command higher prices, even after allowing for size, location and type.
In short, the further a home moves up the EPC scale, the bigger the potential price premium.
What This Could Mean for Kent Homeowners
The average house price in Kent is roughly £390,000 according to recent ONS figures, higher than the UK average. That means even a small percentage uplift is worth a meaningful sum. The figures below are illustrative only and are not a valuation.
| Price uplift | Value added to a £390,000 Kent home |
| 2% (a modest EPC improvement) | About £7,800 |
| 5% (a solid one or two band jump) | About £19,500 |
| 10% (a major improvement, such as F to C) | About £39,000 |
Compare that with the cost of a typical air source heat pump after the £7,500 Boiler Upgrade Scheme grant, which for many Kent homes lands somewhere between £500 and £7,500. In homes in Maidstone, Ashford or Tonbridge that are moving off oil, LPG or old electric heating, the numbers can stack up very well.
Why the Heat Pump Is Only Part of the Picture
The heat pump is only one part of what drives value. The biggest price jumps come from homes that combine low carbon heating with good loft and wall insulation, efficient windows and sensible controls. Think of the heat pump as the centrepiece of an energy efficient home rather than a magic number on its own.
Why Are Buyers in Kent and the South East Looking for Energy Efficient Homes?
Buyers in Kent and the South East are looking for energy efficient homes because the energy crisis made running costs a real part of what a house is worth. In October 2022, the Ofgem price cap for a typical household jumped to £3,549 a year, and only the government’s Energy Price Guarantee held bills at around £2,500. Before the crisis, a typical annual bill had been closer to £1,300. Many households have not forgotten that shock.
That experience changed how people shop for homes. Buyers now ask about EPC ratings, insulation and heating systems as readily as they ask about school catchments and parking. A few local factors make this especially true in our area:
- Commuters and young families. Towns with fast links into London, such as Sevenoaks, Dartford, Gravesend and Ashford, attract buyers who often have tight monthly budgets and pay close attention to running costs.
- Higher house prices. With Kent and the South East among the most expensive regions outside London, buyers want to know that a big purchase will not come with big bills.
- A greener mindset. More buyers want to cut their carbon footprint, and heating is one of the largest sources of carbon emissions in a typical home.
- Rural off gas villages. In areas without mains gas, buyers know that oil and LPG prices can swing sharply, so a home that already has a heat pump stands out.
Does an Air Source Heat Pump Make Your Home Easier to Sell?
An air source heat pump can make your home easier to sell because it gives buyers a clear, practical reason to choose your property over a similar one nearby. A better EPC rating, lower bills and no need to replace an ageing boiler are all strong selling points that estate agents can highlight.
How to Show Off a Heat Pump When Selling
The way you present your heat pump makes a real difference. We suggest you:
- Mention it in the headline of the listing, alongside the EPC rating, so it catches the eye of buyers scrolling through Rightmove or Zoopla.
- Share real running costs. A year of energy bills shows buyers exactly what they can expect, which is far more convincing than an estimate.
- Highlight the comfort. Heat pumps keep a home at a steady, even temperature, which buyers notice on viewings in winter.
- Point out what the buyer will not need to spend. A buyer moving into a home with a modern heat pump avoids the cost of replacing a boiler later.
Why Buyer Familiarity Is Growing
Heat pumps are becoming far more familiar. The UK government has a target of 600,000 heat pump installations a year by 2028, and the Boiler Upgrade Scheme has funded tens of thousands of installations since it launched in 2022. As more people know someone with a heat pump, buyers are increasingly seeing them as a normal, desirable feature rather than something unfamiliar.
How Does an Air Source Heat Pump Affect the Value of a Rental Property?
An air source heat pump affects the value of a rental property by helping it meet energy efficiency rules, appeal to more tenants and hold its value as standards tighten. For landlords, the value of a heat pump is as much about protecting the investment as it is about the sale price.
Meeting EPC Rules for Landlords
Privately rented homes in England and Wales must currently have an EPC rating of at least E under the Minimum Energy Efficiency Standards. The government has set out plans to raise this minimum to C by 2030. Rental properties that fall short could become harder to let and less attractive to buy as investments, while those that already meet a C rating are better placed for the future.
A heat pump, combined with good insulation, is one of the most effective ways to reach that standard, particularly in older or off gas properties.
Attracting and Keeping Tenants
Tenants usually pay the energy bills, so a cheaper to run home is a genuine selling point. Properties with lower running costs can be easier to let, may see shorter empty periods between tenancies and can encourage good tenants to stay longer. This matters in busy rental markets such as Medway, Canterbury and Thanet, from Chatham and Gillingham to Canterbury and Margate.
Practical Benefits for Landlords
- Grant support. Landlords can claim the £7,500 Boiler Upgrade Scheme grant, including on multiple eligible properties.
- Fewer safety certificates. If a property becomes fully electric with no gas appliances, the annual Gas Safe landlord certificate is no longer needed there.
- Stronger portfolio value. As lenders and investors pay more attention to EPC ratings, energy efficient properties are likely to be viewed more favourably when you refinance or sell.
Can an Air Source Heat Pump Ever Reduce the Appeal of a House?
An air source heat pump can reduce the appeal of a house when it has been poorly designed, badly placed or installed without care. The technology itself is not the problem. The issues buyers notice almost always come down to the quality of the installation.
| What can put buyers off | How a good installation avoids it |
| High electricity bills from a badly sized system | A room by room heat loss calculation so the heat pump is the right size |
| Rooms that never feel warm enough | Radiators sized correctly for lower water temperatures |
| An outdoor unit in an awkward or ugly spot | Careful placement, such as a side return or behind planting, away from patios and windows |
| Losing a useful cupboard to a hot water cylinder | Planning the cylinder location with you from the start, including compact or loft options where suitable |
| Confusing controls | Simple controls set up properly, with a clear handover |
The other factor is buyer familiarity. A small number of buyers are still unsure about heat pumps simply because they have not lived with one. Clear information, real energy bills and a confident explanation from your estate agent usually put those worries to rest.
How Can You Get the Most Value From an Air Source Heat Pump?
You can get the most value from an air source heat pump by pairing it with good insulation, choosing an MCS certified installer and setting it up to run as efficiently as possible. These steps improve your EPC rating, cut your bills and give future buyers more confidence.
Improve Insulation First
Loft insulation, cavity wall insulation and draught proofing reduce how much heat your home needs. That lets a smaller, cheaper heat pump do the job and gives your EPC rating an extra boost. The Boiler Upgrade Scheme also requires that your EPC has no outstanding recommendations for loft or cavity wall insulation, unless you have an exemption.
Choose an MCS Certified Installer
MCS certification is the recognised quality mark for renewable installations in the UK. It is required for the Boiler Upgrade Scheme, and it reassures buyers and surveyors that the system has been designed and installed to proper standards.
Add Solar Panels if You Can
Solar panels generate free electricity during the day that your heat pump can use, cutting running costs even further. Together, a heat pump and solar panels can make a noticeable difference to an EPC rating, and homes with both are often marketed as low energy homes.
Use a Smart Tariff and Good Controls
Smart heat pump tariffs from suppliers such as Octopus Energy, British Gas, EDF and OVO offer cheaper electricity at set times. Combined with weather compensation, which adjusts the water temperature to the weather outside, they keep bills low. Low bills are the clearest evidence you can show a buyer.
Keep a Record of Servicing
An annual service keeps your heat pump running efficiently and keeps the manufacturer’s warranty valid. A tidy file of service records shows buyers the system has been well looked after.

Frequently Asked Questions
Will a Heat Pump Change My Council Tax Band?
A heat pump is very unlikely to change your council tax band. Bands in England are based on what a property would have been worth in April 1991, and the Valuation Office Agency typically only reviews a band after major changes such as an extension, usually when the home is next sold. Replacing your heating system is not the kind of change that normally triggers a new band.
Do I Need to Tell My Home Insurer About a Heat Pump?
You should tell your home insurer when you fit a heat pump, as it is a significant change to your home’s heating system. In most cases it makes little or no difference to your premium. It is still worth checking that the outdoor unit is covered against accidental damage and theft, just like any other fixture.
Can a Heat Pump Help Me Get a Green Mortgage?
A heat pump can help you access green mortgage deals if it lifts your home to a higher EPC rating. Several UK lenders have offered lower rates, cashback or extra borrowing for homes rated EPC A or B, or for borrowers making energy efficiency improvements. Deals change often, so speak to a mortgage adviser about what is available when you remortgage or move.
What Do I Need to Tell Buyers About My Heat Pump When Selling?
When you sell, the standard TA6 Property Information Form asks about your heating system, including when it was installed and whether it has been serviced. Keep your MCS certificate, warranty documents, any Boiler Upgrade Scheme paperwork and the user manual together so you can pass them straight to your conveyancer and the buyer. Many manufacturer warranties can be transferred to a new owner, but check the terms of yours.
Can I Add a Heat Pump to a Leasehold Flat?
You can often add a heat pump to a leasehold flat, but you will usually need permission from the freeholder or management company first. Outside walls, roofs and shared spaces normally belong to the building rather than to you. Getting written consent before installation protects the value of your flat and avoids problems when you come to sell.
