MEES (Minimum Energy Efficiency Standards)
The legal minimum energy rating for privately rented homes in England and Wales. Currently EPC E, rising to the equivalent of EPC C from 1 October 2030.
MEES sets the floor for how energy-inefficient a rental property can legally be. Since April 2020 no domestic tenancy in England and Wales can continue below EPC band E without a registered exemption.
The move to EPC C
In January 2026 the government confirmed the standard will rise to the equivalent of EPC C from 1 October 2030, a single deadline covering all tenancies, with enabling legislation expected in 2027. Key confirmed features:
- Compliance will be judged against new EPC metrics (fabric performance first, then a secondary standard such as the heating system or smart readiness), not the current single score.
- A cost cap of £10,000 per property, or 10% of the property value if lower, limits the required investment, with exemptions where compliance still is not achieved.
- Councils will be able to fine up to £30,000 per property per breach.
What to do before 2030
D-rated properties can often reach C with insulation, heating controls, and draught measures; F and G properties are already unlettable without an exemption. Price retrofit costs into any purchase now: an EPC D terrace bought in 2026 carries a known bill before October 2030. Our EPC retrofit calculator models the cost against the yield impact.
