MEES Regulations: Minimum Energy Efficiency Standards for Landlords

The Minimum Energy Efficiency Standards (MEES) regulations set the baseline for energy performance in privately rented properties. Landlords must understand these requirements to stay compliant and avoid penalties.

What are the MEES Regulations?

MEES regulations, introduced in 2018, require privately rented properties in England and Wales to meet minimum energy efficiency standards. Properties must have an Energy Performance Certificate (EPC) rating of at least E to be legally let.

The key rule: It is unlawful to grant a new tenancy or renew an existing tenancy for a property with an EPC rating of F or G.

Current Requirements

Domestic Properties

  • Minimum EPC rating: E
  • Applies to: All new tenancies since April 2018, and all existing tenancies since April 2020
  • Maximum penalty: Up to £5,000

Non-Domestic Properties

  • Minimum EPC rating: E
  • Applies to: All commercial lettings
  • Maximum penalty: Up to £150,000

Future Changes

The government has proposed raising the minimum standard:

Proposed timeline (subject to confirmation):
  • 2028: New tenancies to require EPC C
  • 2030: All tenancies to require EPC C
These dates may change, so check for the latest guidance.

How to Check Your Property's EPC

  • Visit the EPC Register at epcregister.com
  • Enter your property's postcode
  • View the current rating and recommendations
  • Note the expiry date (EPCs are valid for 10 years)
  • Improving Your EPC Rating

    Common improvements to boost energy efficiency:

    Quick Wins (Low Cost)

    • LED lighting throughout
    • Draught-proofing doors and windows
    • Hot water tank insulation
    • Thermostatic radiator valves

    Medium Investment

    • Loft insulation (270mm minimum)
    • Cavity wall insulation
    • Double glazing
    • Efficient boiler replacement

    Major Improvements

    • External wall insulation
    • Ground source heat pumps
    • Solar panels
    • Underfloor heating

    Exemptions from MEES

    You may be exempt from MEES requirements if:

    Cost Cap Exemption

    Improvements would cost more than £3,500 (including VAT) to achieve an E rating.

    Wall Insulation Exemption

    A relevant energy assessor determines that cavity, external, or internal wall insulation would damage the property.

    Consent Exemption

    You need but cannot obtain tenant consent, or third-party consent (such as from a freeholder or planning authority).

    Devaluation Exemption

    An independent surveyor determines that improvements would reduce the property value by more than 5%.

    New Landlord Exemption

    Temporary exemption for landlords who have recently become responsible for a sub-standard property (6 months to register).

    Registering an Exemption

    All exemptions must be registered on the PRS Exemptions Register and are valid for 5 years. After expiry, you must attempt improvements again.

    Penalties for Non-Compliance

    Local authorities can issue penalties for MEES breaches:

    | Breach | Penalty | |--------|---------| | Letting a sub-standard property for less than 3 months | Up to £2,000 | | Letting a sub-standard property for 3+ months | Up to £4,000 | | Providing false or misleading information | Up to £1,000 | | Failing to comply with a compliance notice | Up to £2,000 |

    Note: Publication of the breach on the PRS Exemptions Register for at least 12 months.

    Practical Steps for Landlords

  • Check your EPCs for all rental properties
  • Prioritise F and G rated properties for immediate improvement
  • Budget for upgrades before stricter rules arrive
  • Keep documentation of all improvement works
  • Register valid exemptions if applicable
  • Monitor policy changes for future requirements
  • Frequently Asked Questions

    1. Do I need an EPC if my property is already let? Yes, you need a valid EPC for all let properties and must provide it to tenants. 2. Can I evict tenants to make improvements? You must obtain tenant consent for works, but cannot evict solely for MEES compliance. 3. What if my property genuinely cannot reach an E rating? Register a valid exemption on the PRS Exemptions Register. 4. How often do I need a new EPC? EPCs are valid for 10 years, but you may want an updated one after improvements.
