Energy Performance Certificates

An Energy Performance Certificate ranks a building on a scale from A (best) to G (worst). Under the Energy Performance of Buildings Directive, owners, operators and developers of all buildings in the UK (both domestic and non-domestic) need to provide an Energy Performance Certificate (EPC) for a building when it is constructed, sold or rented.

Our certified assessors have in-depth knowledge of the National Calculation Methodologies, both SAP – for domestic properties, and SBEM for non-domestic properties. The outputs of these calculations is necessary for demonstrating compliance with the Building Regulations. The assessment of a new building is best carried out at design-stage to inform the design process. In doing so you can be assured that the building complies with Part L of the Building Regulations before construction commences.

An EPC is required for all new buildings upon completion, known as an On Construction EPC. fourwalls currently offers On Construction EPC for domestic properties.
