What is Commercial EPC?

All commercial buildings now require an energy performance certificate when they are newly constructed, sold or rented. This means any non-dwelling, i.e. industrial units, retail outlets and offices.

Which buildings are exempt?

• Places of worship
• Stand-alone building of less than 50 square meters (except for dwellings)
• Temporary buildings with a planned time of use of 2 years or less
• Particular building with a low energy demand (e.g. barns)
• In some circumstances buildings to be demolished are exempt from requiring a certificate
• An EPC is not required for any (off-plan) sales or letting before the construction of the building has been completed.

A commercial (non-domestic) EPC is valid for ten years, or until a newer EPC is prepared.

What's involved with an assessment?

Our energy assessor will look at the following building elements:

• The building size and orientation (if you have building plans available, we won't have to measure the building. This will reduce the cost of the assessment)
• Thermal characteristics of the building
• Heating and hot water systems
• Air conditioning
• Ventilation (mechanical & natural)
• Lighting
• Any renewable energy sources
