Minimum Energy Efficiency Standards (MEES) came into force on 1 April 2016 under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. This also applies to residential buildings, required to have an EPC.
Landlords are required to carry out energy improvement works to properties with an EPC rating of less than “E” in order to let or continue to tenant its properties without the face of a fine.
Residential properties with an EPC rating of less than E, may not be let from 1 April 2018, it will unlawful for the landlord to do so. From 1 April 2020 MEES will apply to all residential lettings (new and existing).
As always there are exemptions and landlords can avoid liability where access to funding is not available to meet the cost of improvement, however, a requirement of registration is needed to rely on this exclusion.
