What are the Minimum Energy Efficiency Standards and what do they mean for EPCs?


The MEES, (Minimum Energy Efficiency Standards) regulations came into force in April 2018, and is now a legal requirement for both residential and commercial buildings to have a rating of E or above, before they can be leased.

The regulation has been brought in to help reduce CO2 emissions from buildings. It is estimated that approx. 40% of the UK’s energy consumption and carbon emissions are from buildings alone.

Key Facts
  • MEES came in to force 1st April 2018
  • Currently MEES applies in England and Wales only
  • All properties must be an E or above before a new lease or lease renewal is granted
  • From 1st April 2023 All properties will need to be an E or above even when a lease is already in place
  • MEES does not apply to leases of 6 months or less or 99 years or longer
What if the building does not comply?
  • You cannot legally let the property
  • You may be fined if you sign a new lease on a property that has an F or G rating
Are there any exemptions?

Exception can apply in certain situations, for example:

  • All improvements that meet a seven-year payback period have been installed and the property still falls below the minimum E rating
  • If improvements are to devalue the property by 5% or more
  • If an existing tenant does not allow access to the property for the works to be carried out
