MEES (Minimum Energy Efficiency Standards) for conserving fuel and power

MEES is a set of regulations requiring private sector landlords to ensure that their commercial (and domestic) properties all meet the minimum standard of an E rating on the buildings Energy performance Certificate (EPC).

The regulations come into force for new lets and renewals of tenancies  on 1 April 2018, for all existing domestic tenancies  on 1 April 2020 and all existing non domestic tenancies on 1 April 2023.

It will be illegal to rent a property which breeches MEES regulations  unless there is an applicable exemption.  For non domestic properties, a penalty of up to £5,000 or up to 10% of the rateable value can be imposed for breaches of less than 3 months and may double for longer periods. Non complience may also be publicised. (NB Penalties for breaches in the domestic sector are less)

In preparation for 1 April 2018 it is advisable to ensure that properties all have accurate  EPCs. Where buildings  have  F or G ratings from older EPCs a new EPC carried out with more attention to the actual insulation levels and plant specifications rather than using default values may be sufficient to raise the rating significantly although this may require some further on site investigations and attention to any as built plans, O&M manuals etc that may exist.  If the building still falls below an E rating we can investigate cost effective options that will achieve compliance in conjunction with the landlord.
