Energy ratings for business premises.
From a shop unit to a larger workplace, a commercial EPC helps explain the building’s energy performance. Tell us about the premises and how they are used so the team can quote for the assessment you need.

Check the important details first
What changes the price?
The floor area, premises use, layout and building services help determine the quotation. Send drawings if available and identify the unit being assessed.
Does a home EPC cover business premises?
A business unit uses a different assessment route from an existing dwelling. Describe the actual use and any mixed-use or shared areas so the correct premises can be quoted.
Working to a deadline?
If the report is needed for a sale or tenancy deadline, explain that date at the start. The visit, evidence review and certificate or report timing need confirmation.

A certificate for the space you use.
Commercial premises come in many forms. A self-contained shop, an office floor and an entire building may need different assessment arrangements. Tell us which areas belong to the property, how many floors are involved and whether heating or other services are shared.
What does the assessment look at?
The assessor reviews the building and its services to gather the information needed for the energy calculation. The layout, construction, heating, cooling and ventilation can affect the work. Existing plans and service information help the team understand the property before agreeing the visit.
Prepare for the survey.
Arrange access to the areas being assessed, including relevant plant and equipment where appropriate. Let the team know if the premises are occupied, access is controlled or several businesses share the building. A clear property description helps avoid arranging an assessment for the wrong unit.
What will you receive?
The agreed service provides the commercial energy certificate and relevant recommendations. The energy rating is not a building-condition survey or a safety approval. Discuss any additional documents requested by an agent, landlord or project team before accepting the quotation.
Why is commercial work quoted individually?
Floor area, layout, building services and assessment complexity vary considerably. Send the address, property use, approximate size and any available drawings. The team can then explain the proposed work and price rather than applying a domestic rate to a different kind of building.
Working to a transaction deadline?
Include the date your agent or adviser needs the certificate. Availability, access and the expected report timing must be agreed for the particular premises. Raising the deadline early gives the team the information needed to discuss a suitable arrangement.

About Commercial EPC.
Guidance reviewed 7 November 2026. Read the official guidance.
Why do you ask for floor area?
Area helps describe the work, but building use, systems, access and available evidence also matter. A domestic bedroom price is not a commercial quotation.
Can one instruction cover several units?
Describe each unit and the required boundary. The assessor must confirm the appropriate assessments and outputs rather than assume one record covers all occupation.
Do I need to obtain plans?
Share what you already have and say whether it reflects the current layout. The team can discuss what further information is needed.
Can you work around occupied premises?
Explain occupancy and entry restrictions before the quote is accepted. The team must agree practical access and availability for the actual instruction.
