The DEA will carry out a 'non-intrusive' inspection of your home which should take approximately 1 hour. The inspection purpose is to collect information required to calculate its energy performance such as: room measurements, heating & hot water system details, insulation installed in the property.

The Data collected is then processed using government approved RdSAP software to produce an Energy Performance Certificate. The finished certificate will show the properties (EER) Energy Efficiency Rating and (EIR) Environmental Impact Rating. It will also detail any improvements that can be made to enhance these ratings.

Energy Efficiency Rating (EER) − based on fuel costs.

Environmental Impact Rating (EIR) − based on carbon emissions.
