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.
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.
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.
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.
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.
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.
Review EPC ratings across your portfolio or premises.
Plan for improvements — lighting, HVAC upgrades, insulation, solar PV, low carbon heating or improved controls can all boost ratings.
Consider exemptions — limited cases allow for MEES exemptions, but they must be formally registered and renewed every 5 years.
Budget for upgrades — delaying action may lead to higher retrofit costs later and potential rental voids.
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.
