MEES Regulations
The current minimum under MEES remains EPC E, subject to applicable exemptions — so it is unlawful to let most commercial buildings rated F or G. Following the Government's June 2026 interim response, the intention is to introduce an EPC B requirement from 2031 for privately rented non-domestic buildings over 1,000 m², where cost-effective and subject to the necessary legislation; the previously proposed EPC C milestone for 2027 has been dropped. We help landlords and asset managers identify exposure across portfolios, plan cost-effective upgrades and avoid stranded-asset risk.
