In short

Do you need a commercial EPC, and what is the minimum rating?

You need a valid commercial EPC to build, sell or let a non-domestic property, and under MEES the minimum rating to let is currently E. Since 1 April 2023 it has been unlawful to continue letting most commercial property rated F or G. An EPC is produced by an accredited non-domestic energy assessor and is valid for 10 years.

The minimum standard comes from the Energy Efficiency (Private Rented Property) Regulations 2015 (MEES), and penalties for letting a sub-standard property can reach £150,000.
From 2031 the government has confirmed commercial buildings over 1,000 m² will need to reach EPC B where cost-effective.
You can check whether a property already has a valid certificate on the government's Find an energy certificate service.
Produced by an accredited energy assessor, many of whom are also chartered surveyors, at a level matching the building's complexity.

Why it matters

What is a commercial EPC?

A non-domestic Energy Performance Certificate rates a building's energy efficiency from A (best) to G (worst), and lists the measures that would improve it. It's produced by an accredited energy assessor and is the document that decides whether you can lawfully sell or let, and whether you meet MEES.

Required to sell or let

A valid EPC is legally required whenever a commercial building is built, sold or let.

MEES minimum E rating

Since April 2023 it's unlawful to continue letting most property rated F or G.

Valid for 10 years

One certificate covers repeat sales and lettings for a decade, unless the building changes.

What's involved

What a commercial EPC assessment involves

An accredited assessor inspects the building's fabric, heating, cooling, ventilation and lighting, and records the data needed to model its energy use. That model produces the A to G rating and a recommendation report of improvements. The assessment level, from simpler SBEM calculations to full dynamic simulation, is matched to how complex your building's services are. The certificate is then lodged on the national register.

Penalties for a sub-standard let can reach £150,000
A better rating protects value and future lettability

The compliance clock

The minimum rating is only going up.

Today's minimum to let is EPC E. In June 2026 the government confirmed its intention to raise the standard for larger commercial buildings, over 1,000 square metres, to EPC B by 2031, subject to legislation and a cost-effectiveness test. Knowing your rating now, and the cheapest way to lift it, is how you stay ahead of it.

Questions

Commercial EPC FAQs

How much does a commercial EPC cost?+

It depends on the size and complexity of the building, the number of zones and services, and the assessment level required. As a broad UK guide in 2026, a small, simple unit can start from around £150 to £350, with larger or more complex buildings running to £1,000 or more. You'll get a no-obligation quote.

How long is a commercial EPC valid?+

A commercial EPC is valid for 10 years, or until a newer one is produced for the same building. If nothing has changed you don't have to renew it every time you let or sell within that period, though a better rating is often worth commissioning early to meet MEES.

Is a commercial EPC a legal requirement?+

Yes. A valid non-domestic EPC is required whenever a commercial building is built, sold or let in England and Wales, with limited exceptions. Since 1 April 2023 it is also unlawful to continue to let most commercial property with an EPC rating below E under the MEES regulations.

What is the minimum EPC rating to let a commercial property?+

Under the Minimum Energy Efficiency Standards (MEES), the minimum is currently EPC E. Since 1 April 2018 landlords could not grant a new lease below E, and since 1 April 2023 they cannot continue to let an existing sub-standard property (F or G) unless a valid exemption is registered.

What if my property is rated F or G?+

You generally cannot lawfully let it until it is improved to at least E, or you register a valid exemption on the PRS Exemptions Register. An assessor can identify the most cost-effective improvements, and financial penalties for letting a sub-standard property can reach £150,000 per property.

Who can produce a commercial EPC?+

An accredited non-domestic energy assessor, whose accreditation level matches the complexity of the building. Many are also chartered surveyors. We match you with accredited assessors who cover your area and building type, and you get a no-obligation quote before proceeding.
