What is an EPC Rating and How can it be Improved? 06 Mar 2019

Energy Performance Certificates (EPC) are a system of ratings given to the energy efficiency of a home. Non-residential properties are required to provide what is known as a non-domestic EPC and public buildings are required to show a Display Energy Certificate.

On the back of the Kyoto protocol signed in 1997, it became regulation in 2006 for all member states to show an energy performance certificate in buildings. This was in attempt to reduce greenhouse gasses.

The certificates include a rating system that ranges from A to G which is used to evaluate the efficiency of energy usage per the volume of the household and its occupants. ‘A’ representing high efficiency and ‘G’ representing low efficiency, the higher the rating, the lower the fuel bills for that property are likely to be. It is important to be aware of these ratings, as the minimum requirement to rent out a property is a rating of ‘E’.

A full run down of Energy Performance and Display Energy Certificates can be found via the Ministry of Housing, Communities and Local Government.

How to Improve the EPC Rating of a building?

There are various methods that can be taken to become more energy efficient in your home or property. Eco Partners have listed just a few below:


A large proportion of heat in the household is lost through the roof. Insulating the loft is always a good and relatively inexpensive place to start when it comes to improving the energy efficiency of a property.

Install Renewable Energy Sources:

An option that is widely available to households is the installation of renewable energy sources such as solar panels and solar storage equipment. According to Property Reporter, a G-rated, semi-detached house could make a saving of £311 per year.

Review Existing Appliances:

If you haven’t already, it might be time to assess existing appliances such as boilers to check if they are due for upgrade or replacement. The advantage of using renewables such as solar as your source of power, is that installers such as Eco Partners offer maintenance plans to ensure everything is in working order.  Ratings are calculated using the cost of energy that your heating system is reliant on. An old or faulty boiler could be costing much more in comparison to a solar storage system, which could actually earn you money back from the grid.
