By 2025, Commercial EPC requirements in the UK are undergoing big changes. If you own, let or manage a commercial property, it's time to act.

New rules are coming. Non-compliance may lead to serious penalties. This guide from Gradwell Group explains everything you need to know.

What is an EPC for Commercial Properties?

An Energy Performance Certificate (EPC) rates a property’s energy efficiency.

For commercial buildings, it's a legal requirement. EPCs help buyers and tenants understand running costs and environmental impact.

EPC Ratings Explained:

• A – Most energy efficient
  
  
• G – Least energy efficient
  
  

A valid EPC is needed when:

• Selling or letting a commercial property
  
  
• Making significant renovations
  
  
• Constructing a new commercial building

Why Are EPC Rules Changing in 2025?

The UK government is committed to Net Zero carbon emissions by 2050.

Buildings account for over 20% of carbon output. EPC reforms aim to cut this.

The goal:
All commercial rented buildings must reach at least an EPC Band C by 2027 and Band B by 2030, where cost-effective.

But the 2025 changes are a big step forward.

New EPC Rules for Commercial Properties in 2025

From April 2025, the following changes apply:

1. Minimum EPC Rating of 'E' for All Non-Domestic Properties

This includes existing leases, not just new ones.

Previously, only new leases had to meet the minimum. From 2025, all let properties must comply.

2. Fines for Non-Compliance

If you fail to meet the new standards, you could face:

• £5,000 to £150,000 in fines
  
  
• Public listing on the PRS Exemptions Register
  
  
• Invalidation of lease agreements
  
  

3. More Enforcement, Less Leniency

Local authorities will be empowered to inspect and penalise more actively.

Who is Affected by the 2025 Commercial EPC Requirements?

The changes apply to:

• Commercial landlords
  
  
• Business owners leasing space
  
  
• Managing agents of commercial portfolios
  
  
• Investors buying or selling property
  
  

If you own a retail unit, office, warehouse, or any non-domestic property, this affects you.

Exemptions to Commercial EPC Requirements

You may be exempt from the 2025 rules if:

• The property is listed (and improvements would alter its character)
  
  
• It’s a temporary structure (used under 2 years)
  
  
• It’s a place of worship
  
  
• The cost of improvements exceeds a 7-year payback test
  
  

Tip: Apply to the Exemptions Register to avoid fines.

Frequently Asked Questions (FAQs)

1. Do I Need a New EPC if I Already Have One?

Check the validity. EPCs last 10 years, but if your rating is below E, you must take action.

2. Can I Still Let a Property with an 'F' Rating After 2025?

No. Unless you’ve registered a valid exemption, it is illegal to let properties rated F or G.

3. How Do I Find My Property’s Current EPC?

Visit the official EPC Register and search by postcode.
