EPC Assessment

Energy performance certificates (EPCs) were a part of the now-scrapped home information pack. If you purchased your home after 2007 you may well have one already but if not, we can help. If you are looking at installing a solar PV system, having an EPC is essential in order to receive the full FIT rate.

The government set out legislation that requires a home to have a level D EPC to be able to claim the full feed-in tariff (FIT) rate otherwise it will receive a lower rate – see our feed-in tariff page for the current rates for a residential system.

The government estimated that around half of UK homes meet grade D already, but some properties – and older buildings in particular – may need a little extra help. Measures like energy-efficient boilers and cavity-wall and loft insulation all make the difference.

It’s important to note that a solar PV system counts towards your EPC rating – often enough to take you into the next band up. For example a 4kWp system can add up to 15 points to your EPC rating, which would take a very low band E to a low band D. Even our smallest systems can add four or five points to your rating. So if your house is currently only E rated, by obtaining an EPC after the system’s been installed can take you to band D. Speak to one of our advisers today to find out how efficient your home is.

What does an energy assessment involve?

We’ll take you through the criteria over the phone to estimate your home’s rating, and either one of our accredited surveyors will conduct the survey, or we will arrange for an accredited assessor to visit your home and then provide the certificate and report. This usually costs an extra £60-£100, but is included when you install with us.

What are the key factors affecting my EPC rating?

The surveyor will check over the whole of your property to conduct the EPC survey, and the main aspects they will be assessing are:

  • The type of construction of the building (including walls, roofs, floors and glazing and their thermal performance)
  • The thermal, solar and daylight properties of the building and its air tightness
  • Space heating installation and hot water supply (e.g. boiler type), including their seasonal efficiency, responsiveness and controls
  • Ventilation, air-conditioning systems (cooling) and controls, and fixed lighting
  • The type of fuel and renewable energy sources, e.g. use of sustainable/low carbon technology (solar water heating, ground source heat pumps, wind turbine etc)

What sort of recommendations will be made and what do they mean?

Where you can make energy efficiency improvements in your home

Energy Efficiency Improvements

Along with the EPC certificate, you will be provided with a report of cost-effective recommendations to improve your home’s energy performance. For each improvement it includes the approximate cost, typical cost savings per year and the energy performance rating after improvement.

Examples of recommendations for a home could include the use of low energy light bulbs, loft insulation and cavity wall insulation. The measures will be split into lower cost, higher cost and further measures. To find out whether your home is likely to meet the required level for the FIT scheme, speak to one of our advisors today.
