Frequently Asked Questions

Q What is a DEA?
A  DEAs are accredited and licensed Domestic Energy Assessors

Q Why do I need an Energy Performance Certificate (EPC) to sell my Home?
A  All private dwellings require an EPC to be commissioned before they can be placed on the market, this is an EU directive. The EPC will form part of the Home Information Pack which from August 1st 2008 is a legal requirement for the sale of residential property in the UK.

Q Does an actual survey take place at my property
Yes, an internal and external inspection of the property is carried out by a licensed DEA. They will make a note of the following:

Confirm age of the property
Note the construction of the walls and roof, checking for signs of cavity insulation
Look for green devices (such as solar electric panels or solar water evacuated tubes )
Confirm how many windows are double glazed and when installed
Count number of  fireplaces, open or closed
Check make and model of boiler and the type of flue and fule used
Calculate the number of CFLs (low energy bulbs)
Confirm type of heating system used and controls. 
Measure roof insulation
Measure the thickness of the hot water cylinder jacket or foam.
Check for excessive window area in larger houses and take precise measurements of conservatories and extensions.
Confirm how many 'habitable' rooms are heated.
Measure the internal or external areas of the home.

Sketch and make relevant notes of the home and room  layout

Q What will the Certificate tell me?
A  It will provide you with clear information on the energy performance of the property and cost effective means for improvement. Most of the improvements will be under £500.  Any improvements will make you more comfortable in a warmer and less drafty home. You will also be saving money and reducing your carbon footprint by reducing CO2 emissions

Q My EPC report recommends improvements that I have already made.
A  Your energy report is based on information available to the energy assessor at the time of the assessment. In the absence of information, the assessor will make certain assumptions based on what can be observed. Some recommendations may be inappropriate, e.g. replacement double glazing in a conservation area. You should always check with your local authority before carrying out any recommendation on buildings that are listed or in a conservation area.

Q My EPC report recommends improvements that are inappropriate?
A  Some recommendations may be inappropriate, e.g. replacement double glazing in a conservation area. You should always check with your local authority before carrying out any recommendation on buildings that are listed or in a conservation area.

Q My EPC report recommends cavity wall insulation but I live in an exposed area?
A  If the property is in a very exposed area, or the pointing is poor, or there are signs of water penetration, the energy assessor may remove the recommendation for cavity wall insulation. Only use a reputable installer of cavity wall insulation, who should carry out a site assessment before any installation (visit the National Insulation Association to find out more, and to locate a registered installer in your area).

Q Will the DEA be affiliated to any energy companies or home improvement companies.
No. There will be no recommendations made as to which companies to use for energy improvements.

Q I disagree with my energy report. What should I do?
Firstly, ring your energy assessor and discuss your concerns; most probably you will be able to quickly resolve any problems. If you are still dissatisfied, tell the energy assessor that you wish to make a formal complaint. Every accredited energy assessor has a formal complaints procedure, which you are entitled to see. If you cannot resolve the issue, it will eventually be referred to the energy assessor's accrediting body for a decision. All energy assessors are regularly monitored for quality control purposes. If they fail to perform satisfactorily, they can be required to undertake further training; in extreme cases, thei accreditation will be revoked.
