Energy Performance Certificate and your home

An Energy Performance Certificate is part of a Home Information Pack.
The certificates are commissioned by the seller (or their agent) from an accredited Energy Assessor, who visits the property to collect the relevant data and creates the certificate.

This data includes the date, construction and location of the house and relevant fittings (heating systems, insulation or double glazing, for example).
Why is the Energy Performance Certificate important?

Nearly 40 per cent of the UK's energy consumption arises from the way in which our 25 million buildings are lit, heated and used. Even comparatively minor changes in energy performance and the way we use each building will have a significant effect in reducing energy consumption - and therefore carbon emissions.

Communities and Local Government is leading the introduction of a number of energy and cost-saving measures to make all buildings more efficient. These measures are being applied across all European Union countries and are in line with the European Directive for the Energy Performance of Buildings.

The Energy Performance Certificate is part of these new measures to improve property efficiency. It will include suggestions to enable homeowners to improve the energy efficiency of the building. This can mean lower energy bills for the occupiers, and could make homes more attractive to potential purchasers.

The certificate will also provide contact details for the Energy Savings Trust, who can help you find out whether you could be eligible for grants or discounts to help carry out these improvements to your home. It will also list simple ways that changes in behaviour can save you energy and money - without the need for any works

What the Certificate means

The Energy Performance Certificate (EPC) is similar to the certificates now provided with domestic appliances such as refrigerators and washing machines.
Its purpose is to record how energy-efficient a property is as a building. The certificate will provide a rating of the property from A to G, where A is very efficient and G is very inefficient.

Two ratings are shown. The environmental impact rating is a measure of a home's impact on the environment in terms of carbon dioxide (C02) emissions - the higher the rating, the less impact it has on the environment. The energy-efficiency rating is a measure of a home's overall efficiency. The higher the rating, the more energy-efficient the home is, and the lower the fuel bills are likely to be.

Each rating is based on the performance of the building itself and its services (such as heating and lighting), rather than the domestic appliances within it. This is known as an asset rating. The certificate also lists the potential rating of the building if all the cost-effective measures were installed.

The ratings will vary according to the age, location, size and condition of the building. The potential rating on the certificate will take these factors into account, and the suggested measures will be tailored so that they are realistic for the particular building.
