The quick answer
What is a non-domestic EPC?
A non-domestic Energy Performance Certificate records the modelled energy performance of a commercial or other non-dwelling building. It uses a rating from A+, the best band, to G and is accompanied by recommendations that can help an owner understand possible improvements.
The assessment must follow the approved non-domestic method and be lodged on the official register by an appropriately accredited assessor. It is an energy assessment, not a building survey, fire-risk assessment, asbestos survey, gas certificate or electrical inspection, and it does not guarantee actual energy bills.

This range is not included in the supplied price schedule. Send the property details so a written quote can be confirmed without guessing a band.
Above 1,000 m²
From £0.20 per additional m²
The stated extra-area rate is from £0.20 for each square metre above 1,000 m², equivalent to about 10.7639 ft². Large or complex sites still require an individual quotation.
Quotation factors
Size is only one input
Building use, zones, floors, units, fixed services, plans, access, location, complexity and urgency can affect the final scope and price.
England and Wales guide
When is a commercial EPC required?
GOV.UK says an EPC is required when business premises are rented out or sold, when a building under construction is finished, or where certain changes to separate occupation involve providing or extending fixed heating, air conditioning or mechanical ventilation systems.
Sale
A valid EPC must be made available to prospective buyers for covered premises.
Letting or lease
Owners and agents should address the EPC and any relevant MEES position before marketing or granting a tenancy.
New or altered building
Completion and certain changes to separately occupied parts can trigger the appropriate certificate route.
What the assessor records
The assessment covers the fabric, use and fixed building services
The assessor gathers the inputs needed for the approved non-domestic calculation. The exact survey depends on the building, but these are typical areas of attention.
- Floor areas, storeys, zones and activity types
- Walls, roof, floor and glazing construction
- Heating and hot-water systems
- Mechanical ventilation and air conditioning
- Fixed lighting and controls
- Renewable and low-carbon technologies
- Building orientation and surrounding exposure
- Evidence supporting concealed specifications
The result is modelled using standardised assumptions. It supports comparison between buildings but is not a personalised forecast of operating costs, occupancy patterns or future energy bills.
Prepare the premises
Information that can make the visit more efficient
Give the assessor safe access to all areas within the agreed scope, including plant rooms and controls where relevant. If the building is occupied, arrange a site contact and explain trading, security, induction, parking or restricted-access requirements in advance.
Documents are useful when they reliably show features that are difficult to confirm visually. The assessor decides what evidence can be accepted under the assessment conventions.
Booking process
From scope check to registered certificate
Send property details
Provide the postcode, use, floor area, floors, units, services, access and deadline.
Confirm scope and price
We check the likely assessment route, assessor level, information needed and written quotation.
Assessor attends
The accredited assessor surveys the agreed areas and records the relevant building evidence.
EPC is lodged
The assessment is processed and the completed certificate is lodged through the official register route.
Commercial landlords and MEES
A certificate and the right to let are related, but not identical
For privately rented non-domestic property in England and Wales covered by the current Minimum Energy Efficiency Standard, the present minimum is generally EPC band E unless a valid exemption is registered. Since 1 April 2023, the current requirement applies to all covered privately rented non-domestic property, including where there has been no tenancy change.
The property must first be within the legal EPC and tenancy scope. Exemptions require the correct evidence and registration before they can be relied on. Proposed future standards should not be treated as law until they are enacted and in force.
Choose the correct certificate
Non-domestic EPC, domestic EPC and DEC are different
Non-domestic EPC
Models the energy performance of a commercial or other non-dwelling building or assessed part, normally for construction, sale or letting.
Domestic EPC
Uses the dwelling assessment route for a house or flat. A mixed-use building may need more than one assessment type depending on its arrangement.
Display Energy Certificate
Uses actual energy consumption and applies to certain public buildings frequently visited by the public. It does not replace an EPC where an EPC is separately required.
Why quotations differ
Commercial buildings are assessed at different levels of complexity
The type of assessor needed depends on the building’s features and complexity. Straightforward premises with simple services can follow a different route from a building with complex heating, cooling, ventilation, zoning or specialised construction. The correct level is confirmed before booking.
Part of a building
Units, shared services and separate occupation can affect the assessment boundary and evidence needed.
Mixed-use premises
Residential and commercial areas may require separate domestic and non-domestic assessment routes.
Complex services
Mechanical ventilation, air conditioning, multiple zones and central plant can require a higher assessor level and more site information.

Common questions
Non-domestic EPC FAQs
Straight answers about prices, floor-area bands, legal triggers, validity, MEES, preparation and different certificate types. These visible answers match the FAQ structured data on this page.
What is a non-domestic EPC?
A non-domestic EPC is the Energy Performance Certificate used for a building or part of a building that is not a dwelling, such as a shop, office, restaurant, warehouse or workshop. It records the modelled energy performance on the non-domestic scale from A+ to G and is lodged on the official register by an appropriately accredited assessor.
How much does a non-domestic EPC cost?
Current starting prices are £125 up to 40 square metres, £148 for 41 to 50 square metres, £195 for 51 to 250 square metres, £235 for 251 to 400 square metres, £285 for 401 to 600 square metres and £335 for 651 to 1,000 square metres. The final quotation depends on the building, services, complexity, location, access and assessment level.
Which price applies to premises between 601 and 650 m²?
The supplied price schedule does not state a band for premises from 601 to 650 square metres, so this size is quoted individually. Send the postcode, use, floor area, number of floors and details of the heating, cooling and ventilation systems so the correct scope can be confirmed.
How is a property over 1,000 m² priced?
For floor area above 1,000 square metres, the stated additional rate starts from £0.20 for each extra square metre, equivalent to about 10.7639 square feet. Large, complex, multi-zone or multi-building sites still need an individual written quotation before attendance.
When is a commercial EPC legally required?
GOV.UK says a business-premises EPC is required when premises are rented out or sold, when a building under construction is finished, or when certain changes to separate occupation involve fixed heating, air conditioning or mechanical ventilation. Exemptions can apply, so the building and transaction should be checked against current official guidance.
How long is a non-domestic EPC valid?
A non-domestic EPC is generally valid for 10 years. Check the official register before ordering a new assessment because an existing certificate may still be valid, although a newer certificate replaces the earlier one for practical use.
What should I prepare for the assessor?
Provide safe access throughout the assessed area and, where available, floor plans, measured areas, construction information, previous EPCs, glazing and insulation evidence, lighting details and information about heating, cooling, hot water, ventilation and renewable systems. Clear site and access information helps avoid delays and assumptions.
Is a non-domestic EPC the same as a Display Energy Certificate?
No. A non-domestic EPC models the energy performance of a commercial or other non-domestic building, usually for construction, sale or letting. A Display Energy Certificate uses actual energy consumption and is required for certain public buildings that are frequently visited by the public.
What EPC rating does a commercial landlord need?
For privately rented non-domestic property in England and Wales that is covered by the current Minimum Energy Efficiency Standard, the present minimum is generally EPC band E unless a valid exemption is registered. The property, tenancy and exemption rules matter, so landlords should use the current GOV.UK guidance and take professional advice where the position is unclear.
Can the assessor guarantee a particular EPC rating?
No. The rating is calculated from the building information and fixed services recorded through the approved non-domestic assessment method. The assessor can explain the evidence needed and the completed certificate, but should not promise a band before the assessment or change evidence to reach a target.
