Minimum energy efficiency standards (MEES)

Minimum energy efficiency standards (MEES) are rules that help make rented homes more energy efficient.

You cannot usually rent out a property with an energy performance certificate (EPC) rating below D unless you have a valid exemption.

If your property does not meet the standard

You must improve the property's energy efficiency or check whether an exemption applies.

You could get a fine of up to £5,000 if you rent out a property that does not meet the minimum energy efficiency standards.

Exemptions

You may not need to meet the minimum energy efficiency standards if:

  • you have already made all the recommended energy saving improvements, and the property still has a rating below D
  • the improvements would cost more than £3,500 (including VAT)
  • a specialist has advised that the work needed could damage the property
  • you could not get permission to carry out the work
  • the property is a listed building and does not need an energy performance certificate

If an exemption applies, you must show why it applies and register the exemption

Most exemptions last for 5 years.
