BER assessment fees in Derry typically range from €150 to €250 for a standard home. The price depends on the size and complexity of the property. The fee covers the on-site survey (1–2 hours), data entry into SEAI’s DEAP software, and the official BER certificate. Get quotes from several assessors to compare prices.

The assessor will measure your home’s floor area, wall and roof construction, window types and sizes, heating system (boiler type, controls, cylinder), ventilation, and any renewable energy systems (solar panels, heat pumps). They’ll check insulation in the attic and walls where accessible. Having documentation for any energy upgrades you’ve done (receipts, certificates) helps ensure an accurate rating.

The on-site assessment takes 1–2 hours for a typical home. After the visit, the assessor enters the data into SEAI’s DEAP software and publishes the BER. You usually receive your BER certificate within 3–5 working days of the assessment. If you need it urgently (e.g. for a property sale), let the assessor know when booking.

Yes. A good BER assessor can identify which upgrades will have the biggest impact on your rating. Common improvements include attic insulation (can improve by 1–2 grades), cavity or external wall insulation, upgrading to a condensing boiler or heat pump, and installing solar panels. The assessor can run scenarios in the DEAP software to show the potential rating after each upgrade.
