An Energy Performance Certificate (EPC) is a certificate that is required to sell or rent a property. Before purchasing a property you should make sure the property has an EPC. Carried out by a accredited assessor, this survey looks at the energy efficiency of a property and gives it a rating from A (most energy efficient) to G (least efficient). Using the same scale it also rates the property’s environmental impact. This gives an indication of how expensive the property will be to heat and fuel, and it is the landlord or seller’s responsibility to acquire and pay for one. They can be fined if they don’t produce one when needed. Some buildings do not need one however, if, for example the property:

  • is a temple or church.
  • is a building that will be used for no more than two years.
  • is a building with less than 50 square metres useable floor space.
  • is residential or holiday accommodation that is not going to be used for more than 4 months a year.
