When is an Energy Performance Certificates (EPCs) required?

An Energy Performance Certificate (EPC) sets out the energy efficiency grade of a commercial building. Energy Performance Certificates (EPCs) are required when a commercial building over 50m² is built, sold or rented. There are two grades of buildings under the EPC requirements which relate to the complexity of the building being assessed and will affect the type of EPC assessor you will need.

• a simple building is one having “frequently occurring characteristics" such as simple heating systems, simple natural ventilation and small comfort cooling systems” -- those which are very similar to domestic premises in the fabric and services present, such as a block of shops with flats above them. These buildings are commonly going to be assessed by a Level 3 assessors using SBEM but they can also be assessed by a Level 4 assessor using SBEM or even a Level 5 assessor using DSM.
• a complex building is one having advanced features which can be calculated using SBEM or DSM by a Level 4 or 5 assessor respectively. A Level 4 assessor using SBEM is expected to have experience of buildings in the commercial sector, which may have both fabric and services installations that are not found in domestic buildings, ie. any HVAC systems. A Level 5 assessor using DSM is expected to have experience of buildings in the commercial sector, which may have both fabric and services installations that are uncommon for which the asset rating is best measured using dynamic simulation.

When you search our Register of Low Carbon Energy Assessors you can filter by level of EPC assessor.
