Flow Rate Testing
Flow Rate Testing

Now that Part F of the building regulations for ventilation in domestic dwellings is now being enforced, we can provide a comprehensive testing and certification of flow rates in new build houses. Added to the building regulations in 2010, active enforcement of ventilation flow rates on new builds has only recently begun, and all new builds must adequately meet a range of performance benchmarks. The main changes require have made domestic ventilation ‘Notifiable Work’; any mechanical ventilation system must now be tested, adjusted and commissioned by a suitably qualified person, with a commissioning notice and measured air flow rates reported to the Building Control Body. This includes intermittently used extractor fans and cooker hoods as well as continuously running systems.
