Steps Involved For Energy Surveys

Energy Performance Certificates are legal requirements for properties put up for rent or sale. Therefore, property owners have to hire professionals to conduct energy surveys and issue the necessary documentation. A & C Energy Surveys is one company that you can trust for domestic and non domestic/commercial EPCs in the East Midlands. An extensive survey involves several steps that accredited energy assessors will carry out before giving out EPCs.

Accessing Energy Efficiency

Assessors will visit a residential or commercial building and evaluate the size of usable space. An assessor should measure the dimensions of the property and each room. They will also check the type of construction, the heating, insulation and lighting.

All these elements contribute to energy efficiency. Assessors will use that information to rate your building on a scale of A to G with A being the highest degree of efficiency.

Assessing Light Fittings

As part of the utility analysis, the assessor has to look at the light fixtures around the property. They will go room to room and count the bulbs used, especially the low energy kind. The EPC survey only requires a count of the fixed fittings.

Inspection of Insulation

The type and degree of insulation in a building largely affect its energy efficiency. During an energy survey, the assessor will inspect the structure for insulation. The loft, if available, is one of the crucial parts to evaluate. Inspections of the walls dividing the property are also carried out.

Window Assessment

What types of windows are in the building? An assessor has to check the glazing of the windows if there is any, and how it affects energy efficiency. If the property owner has certificates for some of the installations, the assessor should have them.

Heating Evaluation

A huge percentage of a building’s ratings are based on the heating system. The assessor must evaluate the heating appliances that you use. These units determine the energy and demand rates of the property. Give the assessor the handbook for the boiler if it’s available. Assessors must also factor in the different types of fuels used.


Photographs of the surveyed sections are necessary to include in the final report. An assessor must give an extensive account of every step of the survey. The report includes a plan of the property in case there are any alterations or extensions during the next inspection.

Energy surveys can take 30 minutes to an hour or even longer, depending on the size of the building. Contact A & C for timely and thorough EPC surveys.
