The Domestic Minimum Energy Efficiency Standard (MEES) Regulations are statutory requirements introduced under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. These regulations mandate that landlords of domestic private rented properties ensure their properties meet a minimum energy efficiency threshold, currently set at an Energy Performance Certificate (EPC) rating of E or above. Properties failing to meet this standard cannot be legally let unless a valid exemption applies.
Key Components
- EPC Requirements
- All domestic private rented properties must have a valid EPC, which rates energy efficiency from A (most efficient) to G (least efficient).
- Since 1 April 2020, it has been unlawful to grant new tenancies or continue existing tenancies for properties with an EPC rating below E.
- Exemptions
- Landlords may register exemptions if compliance costs exceed £3,500 (e.g., for insulation or boiler upgrades) or if improvements are technically impossible (e.g., in listed buildings).
- Temporary exemptions also apply during tenancy changes or property acquisitions.
- Enforcement
- Local authorities can impose fines of up to £5,000 for non-compliance.
- Tenants can report non-compliant properties to local enforcement agencies.
Relevance to UK Retrofit Sector
MEES drives demand for retrofit measures such as:
- Insulation (cavity wall, loft).
- High-efficiency heating systems (heat pumps, modern boilers).
- Renewable energy installations (solar panels).
These measures align with the UK’s net-zero targets and reduce fuel poverty in low-income households 2.
Future Developments
Proposed changes to MEES (under consultation as of 2025) may raise the minimum EPC rating to C by 2028 for new tenancies and B by 2030, requiring landlords to invest in deeper retrofits 2.
