Airflow testing and commissioning in East Sussex

Airflow testing measures how much air each fan or valve actually moves, using a calibrated flow hood, and records it against the required rates. It is how you prove a ventilation system works, and for new homes it is part of the building regulations.

Our team is based in Great Barr, Birmingham, and we work throughout East Sussex, from Eastbourne, Hastings, Hove, Bexhill-on-Sea and Hailsham. Servicing, testing and repair visits are charged, and we tell you the cost before booking.

What airflow testing and commissioning involves

Approved Document F expects mechanical ventilation in new dwellings to be tested with a flow device that has been calibrated within the last 12 months, and the results recorded on a commissioning sheet. The person commissioning should be registered with a competent person scheme for ventilation or show evidence of competence; we tell you who will sign your sheet when we quote. Testing is also useful outside new builds: it shows landlords and homeowners whether existing fans meet the rates, and it is the first step in rebalancing an MVHR system that no longer feels right.

Trickle and boost rates measured and set.

Rules in England

English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
