Business Building Certification (EPC & DECs)

Business Building Certification with Envantage

Get Your Business Building Certification


Public and non-domestic buildings are subject to building certification requirements, designed to promote energy efficiency.

These include Display Energy Certificates (DEC) and non-domestic Energy Performance Certificates (EPC).

Failure to produce the correct certification can result in fines, or delay the building, selling or renting of a property.

Envantage provide approved DEC and Commercial EPC Energy Assessors with a suitable level of building inspection qualification, ensuring that you meet requirements.

We also offer advice on your building certification, helping you through the process.

Non-Domestic Energy Performance Certificates (EPC)

All buildings including factories, offices, retail premises and public sector buildings require an EPC whenever the building is built, sold or rented.

All non-domestic EPC’s must either be carried out by or under the direct supervision of a trained non domestic assessor, registered with an approved accreditation body.

There are three levels of building, determined by the building’s complexity and the services it uses:

  • Level 3 – Small buildings, with heating systems less than 100kW and cooling systems less than 12kW.
  • Level 4 – Purpose built buildings, with heating systems greater than 100kW and cooling systems greater than 12kW.
  • Level 5 – Larger buildings that are complex in shape.
