If you’re selling, leasing, or managing a commercial property in 2026, you may be wondering:

Can my building be exempt from needing a Commercial EPC?

While most non-domestic properties require an Energy Performance Certificate, there are specific legal exemptions — but they are limited and strictly defined.

Here’s a clear guide to who qualifies in 2026.

When Is a Commercial EPC Normally Required?

Under the Energy Performance of Buildings (England and Wales) Regulations 2012, a Commercial EPC is required when:

  • A building is sold

  • A building is let

  • A new commercial property is constructed

The certificate is valid for 10 years.

If your property is being marketed without a valid EPC (and no exemption applies), enforcement action can follow.

Full List of Commercial EPC Exemptions (2026)

Below are the most common exemptions recognised in England and Wales.

1️⃣ Listed Buildings (Limited Circumstances)

Certain listed buildings may be exempt if compliance would unacceptably alter the building’s character or appearance.

However:

  • Not all listed buildings are automatically exempt

  • You must assess whether energy efficiency recommendations would impact protected features

Professional advice is strongly recommended before claiming exemption.

2️⃣ Temporary Buildings (Under 2 Years)

Buildings with a planned use of less than two years may qualify for exemption.

Examples:

  • Temporary site offices

  • Short-term event structures

The temporary nature must be genuine and documented.

3️⃣ Standalone Buildings Under 50m²

A detached commercial building with:

  • Total useful floor area under 50 square metres

  • No connection to other structures

may be exempt.

This does not apply to units within a larger building.

4️⃣ Places of Worship

Buildings officially used for religious activities are exempt.

5️⃣ Industrial Sites, Workshops & Non-Residential Agricultural Buildings (Low Energy Demand)

Certain buildings may qualify if they:

  • Have low energy demand

  • Are used for industrial or agricultural processes

However, offices within those buildings may still require an EPC.

MEES Exemptions (Different From EPC Exemptions)

It’s important to understand:

🔹 EPC exemption = No certificate required
🔹 MEES exemption = Certificate exists, but building is exempt from minimum rating rules

Under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, commercial rental properties must generally meet:

✅ Minimum EPC rating of E

If your property is rated F or G, you cannot legally let it unless a registered MEES exemption applies.

Common MEES Exemptions (Commercial)

  • All cost-effective improvements have been made

  • Improvements would devalue property by more than 5%

  • Third-party consent (e.g., landlord, lender, planning) refused

  • Wall insulation would damage building

MEES exemptions must be registered and usually last 5 years.

Can You Simply Claim an Exemption?

No.

You must:

✔ Ensure the exemption genuinely applies
✔ Gather supporting documentation
✔ Register the exemption (if MEES-related)

Incorrect claims can lead to:

  • Fines

  • Enforcement notices

  • Lease delays

What Happens If You Get It Wrong?

Local authorities can impose:

  • Financial penalties

  • Public naming enforcement

  • Restrictions on leasing

This is especially serious for landlords entering lease renewals in 2026.
