How the Minimum Energy Efficiency Standards (MEES) Are Changing – What You Need to Know

The UK’s Minimum Energy Efficiency Standards (MEES) are undergoing significant changes that will impact both commercial landlords and tenants. If you own or lease non-domestic property, now is the time to understand what’s coming — and what it means for your business.

🔍 What Are MEES?

MEES regulations were introduced in 2018 under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. They apply to rented commercial (non-domestic) and domestic properties and are designed to drive improvements in energy performance, helping the UK meet its carbon reduction targets.

Currently, landlords cannot legally let a non-domestic property unless it has an Energy Performance Certificate (EPC) rating of E or better, unless an exemption applies.

⚠️ What's Changing?

📅 From April 1, 2023 (Already in Effect):

• All existing leases of non-domestic rented properties must comply with MEES — not just new lettings or renewals.

• Properties with an EPC below E (i.e., F or G) cannot continue to be rented unless registered with an exemption.

📅 From April 1, 2027 (Planned):

• The minimum EPC rating is expected to rise to C.

• This means any non-domestic property with a rating below C would be unlettable unless improved or exempt.

📅 From April 1, 2030 (Planned):

• The minimum standard is set to increase again — this time to EPC B.

• Only properties rated B or better would be legally lettable.

⏳ Note: These 2027 and 2030 targets are still under government consultation, but they reflect the clear direction of policy: stricter standards over time.

🏢 Who Is Affected?

• Commercial landlords must upgrade buildings that fall short of upcoming EPC requirements.

• Tenants may face disruption, rent adjustments, or lease renegotiations.

• Investors and property managers should reassess portfolios to identify high-risk assets.

💡 What Should You Do Now?

1. Review EPC ratings across your portfolio or premises.

2. Plan for improvements — lighting, HVAC upgrades, insulation, solar PV, low carbon heating or improved controls can all boost ratings.

3. Consider exemptions — limited cases allow for MEES exemptions, but they must be formally registered and renewed every 5 years.

4. Budget for upgrades — delaying action may lead to higher retrofit costs later and potential rental voids.

Final Thoughts

MEES is not just a regulatory hurdle — it’s a key driver of value, resilience, and marketability in property. With the next thresholds looming, proactive energy efficiency upgrades are now a strategic imperative.
