A BER rates the energy efficiency of a property on a scale from A to G. It is legally required when selling, renting, or advertising a property on the market in Ireland. It helps buyers and tenants understand expected energy performance and running costs.

Most domestic BER assessments take 45–90 minutes, depending on the size and complexity of the property. Larger or older properties may require additional time to measure building fabrics and verify insulation details.

An air tightness test (blower door test) measures how much uncontrolled air leakage occurs in a building. Reducing air leakage improves energy efficiency, reduces heating bills, prevents draughts, and minimises moisture-related problems. For new builds, it is also essential for NZEB compliance.

Before your test, ensure all windows and external doors are closed, internal doors are open, trickle vents are closed, and fireplaces are sealed if required. We will guide you through every step on arrival and ensure the building is set up correctly.

Yes. After your BER assessment, we can provide a detailed improvement plan, including insulation upgrades, heating system improvements, ventilation recommendations, and cost-effective measures to boost energy performance and reduce bills.

Absolutely. A pre-retrofit BER is useful when applying for SEAI grants, and it gives a clear baseline of your home’s current performance. This helps us recommend the most effective upgrades and estimate the potential improvement in your final BER rating.
