Ventilation Validation

Q50 is an NSAI‑Registered Ventilation Validator providing independent flow‑rate testing for new builds and retrofits across Ireland. From our base  Laois, we deliver prompt, compliant validation of mechanical and natural ventilation systems in line with the 2019 revision of Part F (Ventilation) of the Building Regulations.

Understanding Ventilation Validation

Since 2019 every dwelling must have its ventilation system independently checked after commissioning. Validation confirms that the installed fans and ductwork deliver the designed supply and extract airflow rates, safeguarding indoor air quality and energy efficiency.

A certified test from Q50:

Verifies compliance
Ensures adequate fresh‑air supply, removing excess moisture and pollutants.
Maximises the performance of MEV, MVHR or demand‑controlled systems, reducing running costs.
Supports BER assessors and SEAI grant applications with recognised certification.

Our Ventilation Validation Service

On‑site measurement – Using calibrated balometers and hot‑wire anemometers we measure airflow at every valve or grille.

Detailed reporting – You receive an NSAI‑compliant certificate and a clear report listing room‑by‑room results, any corrective actions taken and maintenance guidance.
