A valid Energy Performance Certificate is required when a property goes on the market or is rented to a tenant. 

EPCs are produced using standard methods and energy assumptions. This allows owners, prospective buyers or tenants to view the projected energy consumption and carbon ratings over a yearly basis, so they can consider the overall energy efficiency and fuel costs as part of their investment or living expenses.

The best result achievable is an A banding, with the lowest being G.

All EPCs include a recommendations report outlining measures which could improve the energy efficiency rating of a property. Recommendations could include upgrading the heating system, increasing insulation levels in a loft space or replacing single glazing with double glazing.

EPCs are important so we can understand the impact of our energy consumption and carbon emissions produced by the light, heat and general use of our buildings. Relatively small changes such as installing LED lighting can have a positive impact on energy consumption.
