How EPCs are influencing buyer behaviour and property values
If you’re thinking about selling your home, or you’re browsing the market as a buyer, you’ve probably come across the EPC. It’s that coloured chart showing how energy-efficient a property is, usually tucked away near the bottom of a listing. It might not seem as important as room sizes or kitchen fittings, but it’s becoming a bigger part of the decision-making process.
At Paveys, we’re seeing more buyers ask about energy performance during viewings. Sellers too are wondering if their EPC rating will affect how quickly they sell, or whether it could impact the price. The short answer is yes, it can make a difference. Maybe not always in dramatic ways, but enough to be worth paying attention to.
Let’s take a closer look at what EPCs really mean for your sale or purchase, how buyers are reacting to them, and what you might want to consider if your rating isn’t quite where you’d like it to be.
What is an EPC?
EPC stands for Energy Performance Certificate. It gives your home a score from A to G, with A being the most efficient and G the least. The certificate includes an estimate of how much it might cost to heat and light the property, as well as recommendations for improvements.
In the past, the EPC was treated more like a formality. You needed one to sell or rent your home, but most people didn’t look too closely. That’s no longer the case. Energy bills have gone up, and more people are thinking about long-term costs before they buy. A better EPC rating suggests lower running costs, better insulation, and a home that’s more comfortable throughout the year.
It doesn’t mean everyone is only buying A-rated homes, but a solid rating definitely helps build confidence.
Are buyers really checking EPC ratings?
Yes, they are. And not just once the paperwork starts. Many buyers look at the EPC rating before they even book a viewing.
Some are focused on the environmental aspect. Others are more concerned about what it means for their monthly bills. Either way, if a home has a low rating, it tends to raise questions. How old is the boiler? Will it be cold in winter? Is there any insulation in the loft?
On the other hand, if a property has a good rating and recent energy upgrades, that usually reassures buyers. It suggests the home has been looked after and won’t need immediate investment after moving in.
We’ve also noticed that rental investors are paying even closer attention. With minimum energy standards already in place for rented homes, landlords are thinking ahead. Some are avoiding properties with low EPCs altogether to avoid having to carry out improvements later.

Can a good EPC rating increase property value?
It’s not the only factor in determining price, but a better energy rating does have a role to play, particularly when buyers are comparing similar homes in the same area.
What the data shows
| EPC Rating | Impact on Sale Price (avg.) | Buyer Perception |
| A or B | Up to 2% higher | Efficient, low-cost, desirable |
| C | Baseline (neutral) | Meets expectations |
| D or E | 1–3% lower | Slightly less efficient, room for improvement |
| F or G | Up to 5% lower | Outdated, potentially expensive to upgrade |
While not every buyer will walk away from a D-rated home, a stronger EPC can tip the scales, especially when everything else is equal. In more energy-conscious markets, the effect is even stronger.
Should I improve my EPC before selling?
In some cases, yes. But not always.
If your rating is currently E or below, and there are affordable ways to improve it, you might find it’s worth making a few upgrades. You don’t need to retrofit your entire house, but even small changes can help.
Easy upgrades that can improve your rating:
- Add or top up loft insulation
- Install a modern, efficient boiler
- Replace old halogen bulbs with LED lighting
- Draught-proof windows and doors
- Improve heating controls, such as adding a programmable thermostat
These improvements don’t just help the rating, they also make your home feel warmer and more comfortable during viewings. And that’s something buyers notice.
If the required work is costly or complex, it’s often better to leave it and reflect that in your pricing or negotiation.
What if your EPC isn’t great?
Not every home is going to be rated A or B, and that’s completely fine. Especially if your property is older, you might be dealing with solid walls, single glazing, or a heating system that’s a few years past its prime. Buyers understand that. The key is to be realistic and upfront.
If you already know your rating is low, it helps to be prepared for questions. Some buyers will want to know how much it might cost to improve. Others may use the rating as a reason to negotiate. If you’re open about the current energy performance and can explain any improvements you’ve made or potential options for the future, it helps build trust.
And if you don’t plan to carry out upgrades yourself, you can still position the property well by pricing it accordingly and highlighting its other strengths.
How does this affect landlords and investors?
For landlords, the energy rating is even more important. The current rules state that a property must have an EPC of E or better to be legally rented out. But that minimum is likely to change.
There are ongoing discussions about raising the legal requirement to a C rating for all new tenancies, which could be enforced within the next few years. That’s making many buy-to-let investors more selective about what they purchase.
If you’re selling a property that might appeal to landlords, energy performance will be part of their financial calculations. A low rating doesn’t mean you won’t find a buyer, but it may reduce interest or affect what people are willing to offer.

Do mortgage lenders care about EPCs?
Some now do. A few mortgage providers offer better rates or incentives for buyers purchasing energy-efficient homes. This is still a relatively new part of the market, but it’s growing.
There’s also talk of lenders considering EPCs when assessing affordability or future risk. It’s not yet widespread, but the direction of travel is clear and energy efficiency is becoming part of the bigger financial picture for buyers.
Thinking about selling?
Energy ratings aren’t the only thing that matter when selling a home, but they’re definitely growing in importance.
