What is a domestic Energy Performance Certificate and why do I need one?   

A Domestic Energy Performance Certificate (EPC) is a legal obligation for properties that are either for rent, for sale, or newly built. It became effective on October of 2008.

There are 2 ratings issued for Domestic EPC in London. One is the Energy Efficiency Rating which is a gauge of a dwelling’s efficiency as a whole. A high rating means that the dwelling is more efficient in using energy and the effect of this efficiency is lower energy bills. The second is the Environmental Impact Rating. It is a gauge of a dwelling’s impact to the environment in terms of gas discharges such as carbon dioxide. A high rating means a smaller impact on the environment.

Several factors such as the situation, size, age and site of the dwelling will affect the rating. These factors are the basis for the recommended measures that the Domestic EPC contains.

Additional information that Domestic EPC’s must include are:

• Reference Data. e.g. The date of the assessment and the type of property
• A standard estimate will be used for the estimated use of energy. It consists of present and projected energy usage information such as heating and lighting costs and the amount of carbon discharged
• Energy Assessor's details - the assessor’s important information such as name, contact numbers, business or company name
• Complaints method - The Domestic EPC offers a way to convey grievances or a way to verify the certificate’s authenticity
• Energy Counsel - The Domestic EPC offers methods to improve the property's energy rating

The Recommendations Report

The Domestic EPC should also contain a Recommendations Report. This report conveys information about ways to get better energy performance. The report lists the cost, cost savings per annum, and the performance rating if the recommendations are implemented.

Why do I need a Domestic EPC?

A rating of A to G is used to grade the energy efficiency of an evaluated property. These ratings are used to compare the energy efficiency of one building to another of the same category. This information lets the potential buyers, purchasers, and tenants to know the energy efficiency of the property involved. They can then have an idea of how much energy costs they will assume.
