An Energy Performance Certificate (EPC) is required for a dwelling when constructed, sold or let. An EPC informs potential occupiers, tenants or buyers about the energy performance of a building to enable them make informed decisions.
The EPC rating for a building can be calculated using an approved software. An EPC rating is based on the performance potential of the building itself (the building fabric) and the building services such as heating, ventilation and lighting.
EPC rating ranges from A to G where an A rating is most efficient and G rating is least efficient. There is also an A+ rating which is achievable when certain renewable systems have been employed to provide the building services. The better the rating, the more energy efficient the building is likely to be.
An EPC must be accompanied by a recommendation report which provides a list of measures on how the energy efficiency of the building can be improved. The recommendation report also shows an indication of the payback period for each of the measures.
An EPC is valid for up to 10 years and is registered and stored on a national EPC database, enabling all potential lessees or purchasers to review the rating.
