As energy regulations tighten in the UK, commercial property owners and tenants must pay closer attention to Energy Performance Certificates (EPCs). Whether you’re leasing out office space, operating a warehouse, or managing a retail unit, understanding EPC obligations isn’t just about compliance—it’s about future-proofing your business.
🔍 What Is a Commercial EPC?
A Commercial EPC is a legal document that rates the energy efficiency of a non-domestic building on a scale from A (most efficient) to G (least efficient).
It includes:
An Energy Rating Chart
Recommendations for energy improvements
Information on building services (lighting, HVAC, insulation)
🏢 EPCs are mandatory for all commercial buildings over 50m² that are:
Sold
Rented or leased
Newly constructed

🧾 Legal EPC Requirements for Commercial Properties in 2025
✅ Current Law:
Your building must hold an EPC rating of E or above to be rented or leased.
EPCs are valid for 10 years, but may need to be renewed after major upgrades or tenant changes.
⚠️ New Changes on the Horizon:
| Year | Proposed Regulation | Status |
|---|---|---|
| 2025 | New RdSAP 10 EPC Methodology | Enforced |
| 2027 | Minimum EPC Band C for new leases | Proposed |
| 2030 | Minimum EPC Band B for all leases | Proposed |
These proposed upgrades aim to slash energy use in the commercial sector—early action is key.
💸 What Are the Penalties for Non-Compliance?
Non-compliance with commercial EPC or Minimum Energy Efficiency Standards (MEES) may result in:
| Offence | Penalty |
|---|---|
| Renting a non-compliant property (under Band E) | Up to £150,000 fine |
| No EPC at time of sale/rental | Up to £5,000 fine |
| Failure to display EPC in public building | Up to £500 |
🚨 For public buildings over 250m², EPCs must also be displayed prominently.
💼 Can Businesses Apply for EPC Exemptions?
Yes, under specific conditions:
High improvement costs: If recommended changes exceed a 7-year payback threshold
Consent barriers: Landlord, tenant, or planning consent cannot be obtained
Listed or heritage status: Efficiency changes would damage the property’s character
Temporary buildings (in use for less than two years)
All exemptions must be registered officially and renewed every five years.

Lower energy bills
Improved tenant appeal
Access to green financing
