An EPC rates your homes efficiency and the environmental impact it has
An EPC rates your homes efficiency and the environmental impact it has. In the UK it is now law that every property for sale or to rent must have a valid EPC and since April 2020 a property must have an EPC rating of an "E" or above for it to be legally rented out at all.
Since April 2018 it has been unlawful to grant a tenancy to new or existing tenants for a residential or commercial property with an EPC rating of an F or G unless an exemption has been granted, and for residential property, since April 2020 the rules applied to all new and exisiting tenancies. This has meant that only properties achieving an EPC rating of an A to E are legally allowed to be let out.
