MEES stands for Minimum Energy Efficiency Standards: the legal floor under rental property energy performance in England and Wales. The framework is the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 SI 2015/962, which bind landlords, not owner-occupiers. If a property's EPC sits below the floor, it cannot lawfully be let without a registered exemption GOV.UK MEES.
The vintage table
MEES has tightened in steps, and the steps are the story:
| From | Rule | Status |
|---|---|---|
| 26 Mar 2015 | Regulations made (SI 2015/962) SI 2015/962 | In force |
| 1 Apr 2018 | Band E floor for new tenancies and renewals GOV.UK MEES | In force |
| 1 Apr 2020 | Band E floor extends to all continuing domestic lets; £3,500 (inc VAT) landlord cost cap GOV.UK MEES | In force |
| 1 Apr 2023 | Non-domestic: E floor for continuing commercial leases GOV.UK non-dom MEES | In force |
| 1 Oct 2030 | EPC C equivalent standard for all private domestic lets, £10,000 cost cap, 10-year exemptions Gov response Jan 2026 | Confirmed, not yet in force |
How the cost cap works
The cap is the ceiling on what you are required to spend attempting compliance. Today it is £3,500 including VAT per property toward reaching E GOV.UK MEES: spend it on relevant improvements, fall short, and you register an all-improvements exemption rather than spending on. The confirmed 2030 regime raises the cap to £10,000 against the C standard Gov response Jan 2026. Caps include the cost of the works themselves, which is why keeping invoices matters twice over: once for the exemption evidence, once for the RdSAP 10 assessment.
How MEES interacts with the registers
Compliance is checked against the property's EPC on the official register, and exemptions live on the separate PRS Exemptions Register GOV.UK. That means the register entry is the legal reality: if your certificate under-records the house, MEES sees the under-recorded band. Renewing at the right moment is its own decision; see should I renew my EPC now.
Where the detail lives

- Band E vs band C: the two floors side by side
- Exemptions: all six routes and their durations
- Band E: the floor band itself
