Under the MEES legislation, after 1st April 2018, any property with an Energy Performance Certificate (EPC) rating lower than ‘E’ cannot be rented out to new tenants, or renew any existing tenancy contracts until they obtain at least an ‘E’ rating. There are still many landlords in danger of falling foul of the new legislation and will face significant financial consequences. A report published in 2017 stated that there are 115K commercial properties in the UK with an F or G EPC rating – totalling 17.5% of all commercial buildings.
