Energy Performance of Buildings

Energy Assessors

Energy Assessors must be properly trained and qualified and members of a government accreditation body.

These bodies will maintain a list of their members and should be able to provide contact details of assessors local to any BT Postcode.

You will need an accredited assessor that is qualified in the specific area of work to be carried out, for example a DEC assessor can only carry out DEC energy assessments. 

The energy assessor will need to inspect your property, take measurements and gather information on the building.

They will then use a specialised computer program to calculate the energy rating of the property.

Depending on the size, for a house most assessments take about one hour and costs will vary from about £50-£100.

Other properties may take longer to assess and costs will also vary depending on the complexity and area of the building.

The national register of accredited energy assessors is available on landmark Northern Ireland EPC Register website for domestic properties and NI EPC Register Non-Domestic website for nondomestic properties.

If you don’t have internet access you can find a list of EPB assessors in the Yellow Pages under ‘energy assessors’.
