An EPC measures how energy-efficient your property is, rating it from A (extremely efficient) to G (least efficient).
The certificate shows:
The average energy efficiency rating average energy efficiency rating This link will open in a new window for a home in England and Wales is band D, according to the Office for National Statistics (ONS).
By law, since 2018, domestic rental properties in England and Wales must have an EPC rating of E must have an EPC rating of E This link will open in a new window.
However, the Climate Change Committee Climate Change Committee This link will open in a new window recommends all privately rented homes should be rated a minimum of C by 2028, and owner-occupied homes should also reach an EPC of at least band C by 2035.
The higher your EPC rating, the lower your energy bills are likely to be. Less energy is wasted and what you do use goes further. For example, energy-efficient properties retain heat better, so it could cost you less to keep your home warm and comfortable.
According to the Office for National Statistics Office for National Statistics This link will open in a new window, more than a quarter of UK emissions come from households.
Using less energy in the home could reduce the building’s impact on the environment.
CO2 emissions for existing homes in England and Wales were more than twice as high more than twice as high This link will open in a new window as those for new homes, which are typically more energy-efficient.
Some mortgage lenders offer incentives on mortgages for energy-efficient properties (those with an EPC or PEA rating of A or B). For example, HSBC offers cashback on mortgages for energy efficient homes, while other lenders may offer preferential rates.
Your home may be repossessed if you do not keep up repayments on your mortgage.
A higher EPC rating and lower energy bills could make a property more attractive to prospective buyers, if you ever were to sell the property.
Keep in mind – potential buyers may find it difficult to get a mortgage on a property with a low EPC rating, which could make it harder to sell.
If you let a property, it’s your responsibility to provide a safe and comfortable home for your tenants. Improving your property’s EPC rating helps you meet rising energy efficiency standards and could lower your tenant’s energy bills.
You’re also more likely to attract and maintain tenants as you improve the property.
An EPC is typically needed whenever a property is built, sold, or rented.

If your property doesn’t have an EPC or it has expired, you need to have it assessed to get a new energy certificate get a new energy certificate This link will open in a new window. If you’re renting, it’s the property owner's responsibility to provide one.
Keep in mind that not all homes need an EPC, including certain listed buildings. If you’re in the process of buying a property, the seller must show you the EPC.
An EPC can cost between £35 and £120, depending on the size of your home and other factors. It’s worth comparing quotes from a few registered energy assessors in your area to find the best price.

Here are a few things you can do to raise your EPC rating:
If you can afford to, you could consider generating your own power through heat pumps or solar panels as a form of renewable energy.
