An Energy Performance Certificate (EPC) shows you how energy efficient your property is. If you’re trying to sell or rent a property you own it's essential to know your EPC rating. It's also a legal requirement for you to see an EPC if you’re moving into a property. You can find out more information below on EPCs and how ratings can affect your property.

What's an Energy Performance Certificate (EPC)?

An EPC uses a rating scale to record how energy efficient your home is, based on how you power your home. The ratings go from A (very efficient) to G (inefficient). This gives you an idea of how costly it'll be to heat and light your property, and what its carbon dioxide emissions are likely to be.

EPC ratings measure your energy efficiency based on the level of carbon dioxide (CO2) emissions in your home. The higher the rating, the less impact it has on the environment. Each rating is divided into Standard Assessment Procedure (SAP) points. Out of a possible 100 points, each grade signifies the number of SAP points you’ve gained by the energy efficiency of your home. The number of points needed to achieve each grade are:

  • A - 92-100 SAP points (Most efficient)
  • B - 81-91 SAP points
  • C - 69-80 SAP points
  • D - 55-68 SAP points
  • E - 39-54 SAP points
  • F - 21-38 SAP points
  • G- 1-20 SAP points

The EPC also shows you what improvements could make your home more efficient, highlighting ways to achieve a better rating and save money. Even if you rent your home, there are still improvements you could do, such as switching to energy-efficient light bulbs.

You need to get an EPC if you plan to sell or rent your property, to show potential available buyers/renters. You must get your EPC from an approved Domestic Energy Assessor.

If you make your energy efficiency improvements in your home, you may want to get a new EPC to include these.

How much does an Energy Performance Certificate cost?

It costs roughly between £60 and £120 to get your property on the EPC register, so it’s worth looking around and comparing different quotes. Just make sure you choose a registered assessor. You can often lower your energy performance certificate cost by getting your assessment done directly rather than through an estate agent. You can find an assessor in your area by checking on the EPC register.

How do I get an Energy Performance Certificate (EPC)?

The first step to getting an EPC is to find a registered domestic assessor to supply one. Visit the Landmark website to find a registered domestic assessor in your area. You can also search through the EPC ratings of other properties in your area for free. Then you can compare your property’s rating to others in the area - all you need is the postcode.

How do I improve my EPC rating?

There are plenty of changes you can look at making that may increase energy efficiency in your home and improve your overall EPC rating:

  • Replace the insulation in your loft - your home's energy efficiency will increase greatly if your insulation's at least 270mm thick.
  • Insulate your walls - you can get insulation solutions whether you have cavity walls or solid walls.
  • Switch to energy efficient light bulbs
  • Think about replacing your boiler - if you have an older boiler model, a newer energy-efficient model could save you money on your energy bill.
  • Use an efficient secondary heating source - for example, if you have a fireplace, install a wood burning stove.
  • Draught proof your home - this is a quick process that doesn't usually take long, and will make your home instantly warmer and more efficient.
  • Install modern double glazing - replacing older windows can massively help increase energy efficiency.
