It is a legal requirement for any property being sold or let in England, Wales and Northern Ireland, and must be obtained before marketing the property.
An accredited Domestic Energy Assessor (DEA) visits the property and collects data on construction, insulation, heating systems, windows and lighting. This is fed into the Standard Assessment Procedure (SAP) to produce a score from 1 to 100. The assessment takes 30–60 minutes and is entirely non-intrusive.
You need an EPC if you are selling or letting a residential or commercial property, constructing a new building, or in some cases making significant modifications to an existing building.
All rental properties in England and Wales must hold a valid EPC with a minimum rating of E. Properties rated F or G cannot legally be let without a registered exemption. Landlords should plan ahead as minimum standards are expected to tighten to a C rating for new tenancies.
An EPC is valid for 10 years. You can use the same certificate for multiple tenancy changes or a sale within that period, unless you make significant energy improvements and want the rating updated.
The most effective improvements are loft insulation, cavity wall insulation, a modern condensing boiler with full controls, double or triple glazing, LED lighting throughout, and solar photovoltaic panels. Your EPC assessor can advise on which measures will have the greatest impact for your specific property.
