EPC stands for Energy Performance Certificate. Residential or Domestic EPCs were introduced by the European Union (EU) initiative (Directive 2002/92/EC – EPBD) to help improve energy efficiency across all the member states. A Residential EPC is mandatory for residential properties when being sold or let. Ratings are often used by tenants or potential buyers to make energy comparisons between properties. The EPC will identify where there is the ability to improve the energy efficiency of the building.
A Residential EPC rating will depend on:
- The amount of energy used per m²
- The level of carbon dioxide emissions (given in tonnes per year)
A Residential EPC assesses a building by giving a standard energy and carbon emission efficiency grade from ‘A’ to ‘G’. An ‘A’ is the best and ‘G’ the worst, with an average rating of a residential property to date being D/E.
