O’Brien Energy Consulting provided independent assessments of domestic and commercial properties for Building Energy Ratings (BERs) certificates.

However we no longer offer this service as we now provide an Auditing service of BERs to SEAI.

We are not affiliated to any developer, builder, architect, engineer or estate agent, manufacturer or supplier of building materials, heating systems, insulation or renewable energy sources; thus we provided a truly independent assessment of any dwelling.

O’Brien Energy Consulting was a registered BER Assessor, no. 100920.
