From April 2018 legislation is being introduced whereby it will become unlawful to rent your property under an Assured Shorthold Tenancy with an EPC rating of F or G (i.e the lowest two grades of energy efficiency).
Please check that you are compliant by going to the EPC register and making sure you have a current EPC for your rental property and that the energy efficiency rating is band E or above: https://www.epcregister.com/reportSearchAddressTerms.html?redirect=reportSearchAddressByPostcode (an EPC is valid for 10 years).
The new legislation will affect any new lets and any tenancies which are renewing from 1st April 2018. This will be expanded in April 2020 to affect all Assured Shorthold Tenancies. If your property has an energy efficiency rating of band F or G then you will need to undertake refurbishments to increase your rating before reletting or renewing. Additionally, without a current EPC any notice requiring possession will be invalid, so we strongly advise that the EPC record is kept up to date. .
