Commercial EPCs in Norfolk
Commercial EPCs (Energy Performance Certificates) in Norfolk
If you’re selling, leasing, or marketing a non-domestic building, you’ll usually need a valid Commercial Energy Performance Certificate (EPC). Saxon Surveying provides accredited Commercial EPC assessments across Norfolk for offices, retail units, industrial buildings, and mixed-use premises.
A Commercial EPC rates the energy efficiency of a building from A (most efficient) to G (least efficient) and includes a recommendation report highlighting potential improvement measures.
When is a Commercial EPC required?
A Commercial EPC is typically required when:
- A non-domestic building or unit is sold
- Commercial premises are let or assigned to a new tenant
- A building is marketed for sale or lease
- A new non-domestic building is completed
- A building is subdivided into separate units
In most cases, an EPC must be available before marketing begins.

Commercial EPCs and MEES compliance
Under the Minimum Energy Efficiency Standards (MEES), most privately rented commercial buildings in England and Wales must have an EPC rating of E or above to be legally let (unless a valid exemption applies).
If your property is rated F or G, this may:
- Prevent you from granting or renewing leases
- Require improvement works or exemption registration
- Expose you to significant financial penalties
While EPC recommendations are advisory, MEES regulations mean EPC ratings can have direct legal consequences for landlords.
How Commercial EPC assessments work
Commercial EPCs assess the building fabric and fixed services, rather than tenant energy usage. Depending on size and complexity, different assessment methods are used:
- Level 3 EPCs – simple, smaller buildings
- Level 4 EPCs – larger or air-conditioned buildings
- Level 5 EPCs – complex buildings requiring dynamic simulation modelling
The assessment method is determined by the building’s characteristics, not its use.
What we assess during a Commercial EPC
During the site visit, we typically assess:
- Insulation – levels around the home/building
- Heating – system type and controls
- Windows – glazing type and approximate areas
- Construction – walls, floors, roof form
- Renewables – PV/solar thermal/other
- Lighting – low energy fittings where relevant
Common factors affecting commercial EPC ratings
- Heating, cooling, and ventilation systems
- Lighting type and controls
- Insulation and construction
- Building layout and zoning
- Presence of renewable technologies
What to expect on the day
Our Commercial EPC site visits are structured to minimise disruption. We’ll need access to:
- Plant rooms and roof areas (where safe)
- Heating and cooling equipment
- Electrical and lighting systems
- Floor plans (if available)
- Photos may be taken to evidence property features.
- Floorplans may be produced for accurate record taking.
- Survey – our accreditation body may contact you for feedback.
Following the inspection, the EPC is produced using approved software and lodged on the national EPC register.
