When Is a Commercial EPC Required?

Sales, lettings and construction

GOV.UK sets out EPC requirements for business premises, including construction and sale or letting to a new tenant. Certain changes that create more or fewer separately used parts and involve changes to building services can also be relevant.

Describe the actual transaction to the assessor or adviser. An owner selling an entire building and a landlord letting a single unit may need to consider different certificate boundaries. Do not rely only on the name used in a commercial listing.

Check an existing EPC carefully

A valid certificate can generally be reused where it covers the relevant building and has not been replaced by a newer one. Search the official register and compare the exact address, unit and accommodation with the premises being marketed.

A record for a neighbouring unit or an earlier building configuration is not automatically sufficient. If premises have been divided or altered, explain the changes and ask whether the current certificate covers the transaction. Our certificate search guide explains the first checks.

Mixed uses and shared services

A commercial property may contain offices, storage, retail areas and residential accommodation. Different uses and separately occupied parts need to be described accurately. Heating and ventilation arrangements can also affect the assessment scope.

For a shop with a flat above, do not assume that a single commercial certificate replaces the residential documentation. Send plans if available and identify what is included in the sale or lease. The residential versus commercial guide provides examples.

Marketing and provision

The relevant seller or landlord has duties to make the EPC available to prospective buyers or tenants. A buyer's willingness to proceed without it does not remove those duties. Arrange the assessment early enough to provide the required information rather than leaving it until a transaction deadline.

Confirm the assessment scope, access requirements and certificate delivery timescale when booking. Commercial visits can need information about services and access to different zones, so involve the building manager or agent in the arrangements.

MEES is an additional consideration for lettings

The current non-domestic landlord guidance sets an E minimum for covered rented properties, subject to valid exemptions. Since April 2023 the requirement has applied to continuing covered lettings as well as relevant new transactions.

A valid F-rated EPC therefore does not by itself establish that a covered letting can proceed. Check whether the tenancy and property are within scope, then review improvements or the correct exemption route. Commercial rules include a separate cost-effectiveness framework; the domestic spending cap is not the commercial test.

Exemptions and special cases

Some building categories and circumstances can fall outside an EPC requirement, but conditions matter. Industrial use does not automatically exempt every warehouse, and a small unit is not necessarily a qualifying stand-alone building. Heritage and low-energy-demand cases need careful review.

Use the official guidance for the particular property and keep evidence of any conclusion. For MEES, an exemption may require registration before it can be relied upon. A certificate exemption and a minimum-standard exemption should not be confused.

Preparing an enquiry

Provide the address, approximate floor area, current use, available plans and any shared heating, cooling or ventilation information. Tell us whether the premises are occupied and which areas can be accessed. These details help establish a useful quote.

Frequently asked questions

Is an EPC needed just because I run a business?

The duty relates to the relevant building and circumstances, not merely having a business registration. Check the transaction and premises.

Does an existing tenant mean MEES does not apply?

No. The current guidance includes continuing covered non-domestic lettings from April 2023, subject to exemptions.

Can I use the domestic EPC for a flat to cover the shop below?

Do not assume so. Different accommodation and use may require separate certificates.

Are proposed future commercial targets current law?

Do not treat consultation targets as existing duties. This guide uses the current official E-standard guidance and recommends checking updated legislation before future compliance decisions.
