Energy Performance Certificate Services


Energy Performance Certificates

Energy Performance Certificate (EPC) is required by law when a building is built, sold or put up for rent. If you are a landlord or homeowner and need to provide an Energy Performance Certificate (EPC) this will need to be completed by an accredited domestic energy assessor. They will carry out the assessment and produce the certificate. Energy Performance Certificates (EPCs) give information on how to make your home more energy efficient and reduce carbon dioxide emissions.

What does the EPC say about the property?

An Energy Performance Certificate gives clear information about the energy performance of a property. An EPC will also make recommendations about how the property could improve it’s energy performance.

How long does it take to perform an EPC assessment?

An assessment takes anywhere from 25 minutes to 1 hour for a domestic EPC and a couple of hours to a couple of days for a Commercial EPC depending upon the size of the commercial property. Factors such as the size of the property, it’s age and general access to it, will have an influence on the time. Generally, an energy assessment won’t cause much inconvenience but, it’s important that the energy assessor can get access to any loft space and heating appliances (e.g. a boiler). An internal and external inspection of the property is also required for a certificate.



What is an energy assessor looking for?

  • Noting the construction of the walls and checking wall insulation.
  • Confirming how many windows are double glazed.
  • Counting the number of open fireplaces.
  • Checking the make and model of the boiler under EU SEDBUK regulations.
  • Looking for green energy devices such as solar panels.
  • Counting the number of low energy light bulbs.
  • Confirming the type of heating system used e.g. gas, electric, underfloor etc.
  • Noting down the type of material used to insulate any hot water cylinders.
  • Assessing the heat loss through roof, check loft insulation.
  • Checking for excessive window area in larger houses.
  • Taking precise measurements of conservatories and extensions.
  • Counting how many habitable rooms are heated.
  • What is the procedure once the assessor has visited?

    Once the assessor has visited property, the information is uploaded onto the Government authorized software. A certificate is produced and emailed to the customer within 24 hours after the payment is received.
