Frequently Asked Questions

What is an EPC?

Energy Performance Certificates (EPC) are required by law when a building is built, sold or put up for rent. If you are a landlord or homeowner and need a Energy Performance Certificate (EPC) this will need to be completed by an accredited DEA. They will carry out the EPC 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 an EPC show?

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. http://www.epcstoke.org.uk/?page_id=25

How long does it take to complete 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). Internal and external inspection of the property are required for a certificate.

What will the assessor be looking at?
  • Noting the construction of the walls and checking wall insulation.
  • How many windows in the property 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.
  • how many habitable rooms are heated in the property.
What is the procedure once the assessor has been?

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