What is an EPC - Energy Performance Certificate – and do I need one to sell or rent my home? Or am I exempt? How much do they cost? How quickly can I get one? And why are they so important? We've got all the answers...
An EPC – or Energy Performance Certificate – ranks properties in terms of energy efficiency. The most energy efficient homes are rated A while the lowest are rated G. This rating will take into account the potential energy performance of the property itself and its services, such as heating, hot water etc.
EPCs use a colour coded system so that you can clearly see the rating – it’s like when you buy a new kitchen appliance, which has a coloured sticker telling you how energy efficient the appliance is.
EPCs also include:
EPCs are valid for 10 years from the date of issue, or until a newer Energy Performance Certificate is created for the same property.
However, when looking at the EPC rating, bear in mind the energy efficiency rating uses ‘standard occupancy’ assumptions which are typically two adults and two children. This could be very different from how the people living in the house actually use things like heating and lighting in the home.
Yes, you need an EPC when you’re selling a house or renting out a property in England, Wales and Northern Ireland. An EPC is also required when a property is built.
Sellers in Scotland have to provide a more extensive “home report”, which includes an EPC, as well as a survey and a property questionnaire.
An EPC must be commissioned before the property is put on the market and it must be available to be shown to prospective buyers or tenants if requested. However, there are some exemptions – read on for more on these.

No, there is no minimum EPC rating to sell a property. However, a higher EPC rating may make your property more appealing to potential buyers.
Listed buildings may be exempt from needing an EPC, although the government says ‘you should get advice from your local authority conservation officer if the work would alter the building’s character’.
EPCs are not required for:
You may already have a valid EPC and it’s easy to find out by checking the government’s EPC register in England and Wales. For properties in Scotland check the Scottish EPC register and similarly the Northern Ireland EPC register.
The requirement to have an EPC has been the law since 2008, so it may have one. However, once completed, the EPC is only valid for 10 years.

We’ve looked at what is an EPC – now how do you read them? EPCs differ depending on where abouts in the UK your property is located and whether it’s a new build or existing property. But every energy performance certificate will include the basic information first such as the property type, address and floor size. It will also include the Domestic Energy Assessor’s name and contact information.
Here’s what your EPC contains in more detail:
There are a number of ways you may benefit from a good EPC rating including:
If you do not get an EPC when selling a house or you’re a landlord renting out a property, you could be fined up to £5,000.
If you’re letting out your property it must have a minimum EPC rating of E unless you qualify for certain exemptions.
Under the Minimum Energy Performance of Buildings Bill, the government had proposed to increase this to a minimum EPC rating of C for new tenancies from 2025 and for all rental properties by 2028, where practical, cost-effective and affordable. Under the current rules the amount landlords need to spend in order to get properties up to EPC band E is £3,500. Then they can register an ‘all improvements made’ exemption. But under the proposed changes this threshold would have increased to £10,000.
But in September 2023, the government said it would ‘scrap policies to force landlords to upgrade the energy efficiency of their properties’. And instead they will be encouraged to ‘do so where they can’.
However, if you’re a landlord there are reasons why you may still wish to improve your property’s energy efficiency, for example it may make the property more appealing to new tenants as their heating bills will be lower.

If you’re looking to buy a property, the EPC rating should be shown on the property listing. If it isn’t, speak to the estate agent or alternatively you can go to the EPC register to search by address.
So what is an EPC useful for if you’re buying a house? It’s an important source of information. It will tell you how much you’ll be likely to pay on your energy bills and what changes you can make in the future to improve the property’s energy efficiency – and how much these improvements are likely to cost.
EPC ratings are important for homeowners too. While you live in your home there are no rules on the minimum EPC rating you have to have. But the lower the band your property is in the more you’re likely to have to spend on your energy bills. Analysis by property consultancy JLL found a typical household living in a home with a rating of G would pay a staggering £3250 a year more for their energy than those in properties in Bands A, B and C.
And plans are afoot to try to encourage homeowners to increase their EPC rating. In the Minimum Energy Performance of Buildings Bill, the government proposes that it wants all homes to achieve at least an EPC band C by 2033 ‘where practical, cost-effective and affordable’.
The steps you can take to improve your EPC rating should be listed on your EPC. However, some of the common ways to improve a property’s energy efficiency are:
You don’t have to. But if you’re aiming to improve your EPC rating, then we would recommend getting an Energy Performance Certificate before (If you don’t have a valid one) and after the changes. This will allow you to track the impact of your energy efficiency improvements.
We advise using the same assessor or firm to avoid the risk that even after improvements are made, a discrepancy in approach or equipment used in the assessment means you don’t get a higher rating. You could also ask the assessor’s advice on your home improvements before you invest.
If you want to challenge your EPC rating or your certificate contains an error you should contact the energy assessor who carried out the report first. You’ll find their details on the energy performance certificate and you can ask them to re-assess your home based on your concerns. For example if you think they recorded the wrong appliances on your EPC or that they missed off an important factor. But if you’re not happy with the response you can appeal to the accreditation scheme the assessor is licensed by. You should also find the details on your certificate.
Similarly if you have any queries your first point of contact should be the energy assessor who carried out the report. And if they can’t help, contact the accreditation scheme.
If you’re considering what is an EPC you may be asking what will fail an EPC. But there is no pass or fail, you simply get a rating and a score. Although, as we explain above there are different rules for landlords.
No. To get an EPC for your property in the UK, you’ll need to use an accredited energy assessor.
