Minimum Energy Efficiency standard (MEES). 

The Domestic Minimum Energy Efficiency Standard (MEES) Regulations set a minimum energy efficiency level for domestic private rented properties.

The Regulations apply to all domestic private rented properties that are:

  • let on specific types of tenancy agreement
  • legally required to have an Energy Performance Certificate (EPC)

The current minimum energy efficiency rating, the figure shown on your energy performance certificate, is E.  This means that F and G rated properties cannot be rented out.  There are certain exemptions, but if you want to rely on these exemptions you must register them on a national register.

The prohibition on letting property below an EPC rating of E does not apply if the cost of making even the cheapest recommended improvement would exceed £3,500 (inc. VAT).

Where all the “relevant energy efficiency improvements” for the property have been made (or there are none that can be made) and the property remains sub-standard, an exemption can be applied.

Where the landlord has obtained written expert advice indicating that the recommended measure is not appropriate for the property due to its potential negative impact on the fabric or structure of the property (can apply to cavity wall insulation, external wall insulation or internal wall insulation (for external walls)).

Where improvements cannot be made because consent could not be obtained from a third party, you may be able to register this as an exemption for 5 years.

An exemption from meeting the minimum standard will apply where the landlord has obtained a report from an independent surveyor who is on the Royal Institution of Chartered Surveyors (RICS) register of valuers advising that the installation of specific energy efficiency measures would reduce the market value of the property, or the building it forms part of, by more than five per cent.

New landlord may also be able to apply for an exemption of 6 months, in certain circumstances.

There are proposals for this minimum rating to increase over time to a C-rating.  Landlords are advised to look now at whether your property already complies with the current minimum rating and if the correct exemption has been registered.
