When are assessments required?
An Energy Performance Certificate is only required when a building is constructed, sold or rented out. An EPC is valid for 10 years, except for sales of homes which are subject to the Home Information Pack Regulations 2007, where a Home Information Pack (HIP) is required. In these cases an EPC must be no more than 12 months old when the property is first marketed.
When the construction of a new building is completed, the builder or person responsible for the construction is responsible for obtaining the certificate and providing it to the owner. This is a duty under Building Regulations. This will also apply if a building is converted into fewer or more units and there are changes to the heating, hot water provision or air conditioning/ ventilation services.
Homes will require an EPC on construction or such conversion from 6 April 2008. Some commercial buildings will require an EPC on construction or such conversion from this date. See ‘When the measures being introduced’ for more details.

For existing buildings that are to be sold, the building’s owner is responsible for ensuring a certificate is made available to all prospective purchasers at the earliest opportunity. For guidance on property particulars and when certificates need to be made available, see Property particulars and making EPCs available to prospective buyers and tenants
Homes sold without marketing for sale e.g. by private treaty between family members or Local Authority housing will require an EPC on sale from 1 October 2008.
