Commercial EPC (NDEPC) for the South West

A Commercial EPC — technically a Non-Domestic Energy Performance Certificate (NDEPC) — is a legal requirement for every commercial building sold, let or newly built in England and Wales. Our accredited Non-Domestic Energy Assessors (NDEAs) produce Level 3 EPCs using SBEM modelling for offices, retail, industrial, hospitality and mixed-use property across the South West.

What is a Commercial EPC?

A Commercial EPC (NDEPC) is a legally-required rating from A to G of a non-domestic building's energy performance, produced from an SBEM asset-rating model. Certificates are valid for 10 years and lodged on the EPC Register.

When do you need one?

On sale, on grant of a new lease, on assignment of an existing lease, and on practical completion of a new build or major refurbishment. The certificate must be advertised on the marketing particulars.

MEES (Minimum Energy Efficiency Standard)

Since April 2023 it is unlawful to continue to let a commercial property rated F or G without a registered exemption. The minimum is expected to rise to Band C in 2027 and Band B in 2030 for all lettings.

Frequently asked questions

How much is a Commercial EPC in the South West?

From £250 for small offices, shops or units up to ~500 m². Medium (500–2,000 m²) typically £400–£800. Larger and complex properties individually quoted. No VAT.

How long is a Commercial EPC valid for?

Ten years from the date of lodgement on the national EPC Register — unless the building undergoes material alterations that affect its energy performance.

What is SBEM and why does my Commercial EPC use it?

SBEM (Simplified Building Energy Model) is the government-approved calculation engine used to produce every non-domestic EPC in England and Wales. Our NDEA assessors model your building in iSBEM and lodge the resulting NDEPC on the EPC Register.

What happens if my property is rated F or G?

Continuing to let it is unlawful without a registered PRS exemption. We pair every commercial EPC with an optional MEES Commercial Advice Report so landlords have a costed compliance pathway.

Do you cover Bristol and Bath?

Yes — commercial EPC assessments across Bristol, Bath and the North Somerset corridor alongside our wider South West work. See the /commercial-epc-bristol page.
