SEAI Registered BER Assessors Ireland

A Building Energy Rating (BER) certificate rates your home’s energy performance on a scale from A1 (most efficient) to G (least efficient). It’s similar to the energy label on household appliances. The BER is based on the home’s structure, heating system, ventilation, and renewable energy sources. A BER certificate is valid for 10 years and is legally required when selling or renting a property in Ireland.

A BER certificate is legally required when selling or renting a property in Ireland. You also need a new BER assessment before and after any work carried out under SEAI home energy grants — this is how the improvement is measured. If you’re planning energy upgrades like insulation, heat pumps, or solar panels, getting a BER assessment first helps identify which improvements will have the biggest impact on your rating.

A typical BER assessment for a standard 3-bed semi-detached house costs €150–€250 including VAT. Larger or more complex homes may cost more. The assessment usually takes 1–2 hours on-site. The assessor measures the home, inspects insulation, windows, heating systems, and any renewables. The fee covers the on-site survey, data entry into SEAI’s software (DEAP), and the official BER certificate.

All BER assessors must be registered with SEAI. Check that your assessor is on the SEAI register before booking. Compare quotes from 2–3 assessors in your area. A good assessor will ask about your home’s construction year, any upgrades you’ve done, and whether you have documentation for insulation or heating systems. They should also be able to advise on the most cost-effective upgrades to improve your rating.
