The Provisional BER & Part L Compliance Report

What is a BER?

A BER (Building Energy Rating) Certificate details the calculated energy usage and carbon dioxide emissions specific to your dwellings design and specification.

The BER results are determined from the calculation of the heat losses through the building fabric in conjunction with the amount of energy required to sufficiently run your dwelling e.g lighting, heating etc.

Similar to that of an electrical appliance label, a BER rates the building from an A1 (being the most efficient) right down to a G (being the least efficient). All BER Certificates are accompanied by an Advisory Report, which outlines recommendations on how the energy performance of your dwelling can be improved.


A BER Certificate is compulsory for all new build homes prior to occupation.  It should also be noted that if you are selling or letting a dwelling, a BER is required.


What is a Provisional BER Certificate

During the design stage new builds are rated off plans. Lasting for 2 years, a Provisional BER will be calculated on the design and specification on the house plans.  Upon occupation of the dwelling a full BER will be required to be carried out. This BER will last for 10 years.

What is a Part L Compliance Report

The BER Assessor uses the DEAP (Dwelling Energy Assessment Procedure) software tool from SEAI to calculate and produce the BER Certificate.  This tool is also used to produce the Part L Compliance Report, which demonstrates compliance/ non compliance with the Energy Performance of Buildings Directive in Ireland.  This Report is uploaded to the the BCMS (Building Control Management System) when applying for a Commencement Notice.  Furthermore, the Part L Compliance Report benefits the SelfBuilder giving the opportunity to look at feasible designs to upgrade the energy performance of the proposed dwelling prior to construction.  Remember it is cheaper to make changes at design stage rather than half way through the Construction phase!



Need Further Information about BER?

Should you require any further information about the BER process you should contact the SEAI (Sustainable Energy Association of Ireland) on 1890 734237 or email them on info@ber.seai.ie. The SEAI have also produced a BER Information leaflet which can be downloaded here
