Assessments usually take around 30 minutes on site for a three/four bedroom sized house. Your assessor will need access to every room in the property, including living rooms, bedrooms, bathrooms, loft rooms, attics and basements. They will walk around the property and sketch a floor plan, capturing all room dimensions.

• For EPCs the assessor will need to collect key information that affects the energy efficiency of the property. For example the type of heating system / boiler / immersion tank, radiators, windows, lights, insulation, thermostats and the electric meter. They will take photos where necessary to provide evidence of the information they capture.
• For floor plans the assessor will take photos of the position of kitchen and bathroom facilities, e.g. the position of the hob, sink, bath, shower within the rooms they are in.

If any room in the property is not accessible, for example people sleeping in a bedroom, someone using the bathroom etc, the assessor will not be able to complete the assessment.

The assessor may require documentary evidence to prove the existence of elements that can’t be visually checked, e.g. insulation under floors or inside walls.

The certificate is usually produced within 24 hours of the assessment taking place. Once we receive your payment we will lodge the new EPC on the EPC Register and we will email you a link to it.
