How will BER of New Dwellings be carried out?

The person or organisation building the new dwelling will engage a BER assessor to carry out the BER. That BER assessor may be a professional in private practice (in which case an agreed fee will apply) or, in the case of a local authority, may be an employee of that authority. All BER assessors will be required to follow a standardised procedure using an approved calculation methodology.

Normally a BER certificate and advisory report will be issued by the BER assessor on the basis of the plans and specifications of the new dwelling “as constructed”.

In the case of new homes being sold (or let) “off the plans”, a BER assessment may be carried out on the basis of the plans and specifications for the intended dwelling in which case a provisional BER certificate and advisory report will be issued by the BER assessor. However, a BER certificate must subsequently be issued when the dwelling is completed, which take must account of any relevant variations made to the details of the new dwelling during the construction phase.

A need for provisional BER certificates is normally expected to arise only in the case of group housing developments, in estate or apartment form. A provisional BER certificate lapses on completion of the dwelling or after 24 months, whichever is the sooner.
