What is an EPC?

The Energy Performance Certificate is broadly similar to the certificates found on many domestic appliances.

A Certificate for a building gives the building an asset rating based on its energy efficiency, but doesn't take into account how the home is used by the occupiers.

The Certificate will give the building a rating from A to G. An A rating shows it's very efficient, meaning lower fuel bills, while G is inefficient, meaning higher fuel bills. The Certificate will also show the building's environmental impact by indicating its carbon-dioxide emissions.

There will also be recommendations for cost-effective actions to improve the building's rating. The potential rating is based on all the recommendations being implemented.

EPC's will contain:
 
- Energy Rating (RDSAP)
- Carbon Rating
- Running Cost Indicators
- Improvement Suggestions
 
How is an EPC Calculated?

For an assessment to be made a visit to the property is required - except for new build which is calculated from plans.  At that visit we will need to conduct a full survey of the property, including the roofspace and will be recording specific details to input into software used to calculate the energy rating.

The details required will include:

  • The age of the property
  • The floor area
  • The length of the external heat loss perimeter walls
  • The thickness of the walls
  • Cavity wall insulation and type
  • Roofspace insulation and depth
  • Make, model and age of central heating boiler
  • Type of central heating boiler and flue
  • Method of heat radiation (radiators, under floor etc.)
  • Number of Thermostatic Radiator Valves (TRVs)
  • Number of fireplaces
  • Form of any other secondary heating
  • Type of windows
  • Type, age and extent of double glazing (if any)
  • Number of low energy light fittings

How you can help us

We will do all we can to be on time and will complete the assessment professionally, accurately and honestly.

To help in this objective if you could:

  • Have any guarantees, warranties or invoices to hand for any energy saving installations including central heating boiler, double glazing, cavity wall insulation etc.
  • Make sure that there is an adult at the premises for the duration of the inspection. Our Assessors will not be able to carry out or complete the survey unless that is the case (unless we have written prior authority from parents and the child agrees).
  • Please make sure all parts of the property are unlocked and accessible including basements and attic spaces.
  • Make sure all pets are locked away in an ‘out house', car or off the premises.
  • Please make sure you have not left money or jewellery on display and if there is anything that could be easily broken, please put it away.
  • We will, in most circumstances, need access to the roofspace.

Things You Should Know

We will complete our assessment in a professional and efficient manner, the ultimate objective being accuracy not speed.

We have a well practiced routine to follow so that all information is recorded efficiently.  This will mean getting access to all parts of the property.

The average UK rating of a domestic property is ‘E' on the A-G scale.  Please do not be concerned if your property does not reach the rating you expected as this depends on many factors - including the age of the property, type and age of boiler, insulation thickness etc

Your EPC will be sent to you by your chosen method (postal or electronically) once the calculations have been completed.
