How will the BER audit be carried out?


A BER of an existing dwelling being offered for sale or letting on or after 1 January 2009 must be carried out by a BER assessor, at the expense of the vendor or landlord – who must provide the resulting BER certificate and advisory report to prospective buyers/tenants.

The BER assessor will normally survey the dwelling to record, for example, the size of the dwelling, the construction, the insulation levels, the types of windows, the ventilation features, details of the heating and hot water systems, etc.

This information will then be used to calculate the energy performance of the dwelling and to give it an energy rating.

All BER assessors will be required to follow a standardised procedure using an approved survey and calculation methodology to arrive at a rating.
