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.
Every job in Herefordshire gets a written quote before it starts and a commissioning record when it finishes. We cover Ross-on-Wye, Hereford and Leominster and the villages around them.

How we do it
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.
MEV and dMEV commissioning
Trickle and boost rates measured and set.
MVHR commissioning
Supply and extract at every valve measured and balanced.
Remedial advice
If a fan fails, we explain why and quote the fix.
