Key attributes of a good BER assessor
- SEAI Registered – The most important check. Make sure they are currently registered with the Sustainable Energy Authority of Ireland.
- Fully qualified – They should have the appropriate qualifications and training to carry out BER assessments.
- Experienced – Look for experience with properties similar to yours, whether residential, commercial, new-build or older buildings.
- Accurate and thorough – A good assessor should inspect the property carefully, take measurements and gather the necessary information rather than making assumptions.
- Good knowledge of building construction – Understanding insulation, windows, heating, ventilation, lighting and building fabric is important.
- Knowledge of DEAP/NEAP methodology – They should understand the calculation methodology used to produce the BER.
- Local experience – An assessor familiar with your area may have good knowledge of common property types and local building practices.
- Independent and impartial – They should provide an objective assessment rather than using the BER as a way to push particular products or services.
- Clear explanation – They should be able to explain your BER rating in straightforward language and identify the main factors affecting it.
- Energy improvement advice – Ideally, they can suggest practical measures that could improve the property’s energy efficiency and BER rating.
- Attention to detail – Small details about construction, heating systems, insulation and glazing can affect the assessment.
- Professional and reliable – Look for punctuality, good communication and a clear process from initial inspection through to certification.
- Transparent pricing – The quotation should clearly explain what is included and whether there are any additional charges.
- Good reputation – Check reviews, testimonials and, where possible, examples of previous work.
- Professional insurance – Appropriate professional indemnity insurance is another useful indicator of a properly established assessor.
If it’s for a commercial property:
Place extra emphasis on commercial BER experience, familiarity with larger or more complex buildings, and experience with NEAP assessments, where applicable.
Top 5 to prioritise:
SEAI registration • Qualifications • Experience • Accuracy • Independence
And before appointing anyone, verify their current SEAI registration rather than relying solely on their website or advertising.
