Energy Performance Certificate

General Information.

The Energy Performance Certificate ratings provide a measure of the overall energy efficiency of your property and its environmental impact. Both are calculated using the Reduced Data Standard Assessment Procedure (RDSAP), which is the government's recommended system, hot water system, fixed lighting, number of windows and fuels used.

The ratings are expressed on a scale which will look very similar to those found on domestic appliances. The higher the energy efficiency rating the more efficient the home.

The average household in the UK creates about six tonnes of carbon dioxide every year. There are simple steps you can take to cut carbon dioxide emissions and help to prevent climate change. Making your home more energy efficient by adopting the suggestions on our recommendations page can help protect the environment by reducing carbon dioxide emissions.


The inspection will last approximately 1 hour depending on the size of property. In exceptional circumstances, more time may be needed. Prior to the assessment, you may be asked to complete a Seller's Questionnaire which gives the DEA information needed to prepare properly for the assessment. Identification of the age, construction, materials, services provided and available and measurements form the basis for the inspection of the building, therefore the DEA needs access to the exterior of the property, all rooms in the house plus any cellars, lofts or rooms-in-the-roof. During the assessment, the DEA undertakes a methodical visual inspection of all relevant parts of the property, takes measurements and makes notes. The DEA needs to see the boiler and any gas or electricity meters. Your permission will be sought to take photographs to support the information recorded about the property. The inspection is not destructive or invasive and won't cause any significant permanent marking, damage, harm or injury to the building fabric. Reporting on the condition of the property and any improvement costs is outside the scope of the Energy Performance Certificate. After the assessment, you may be asked to complete a Quality Assurance Consent Form. This form is provided by the NHER Accreditation Scheme and seeks your permission to help them with auditing of the Domestic Energy Assessor. You don't have to give your consent; the form asks for your contact details only and does not require you to comment on the DEA's performance.
