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.


At Q-Tec, our team includes engineers fully qualified to carry out this work with all the latest equipment necessary for testing and certifying any of the three types of domestic ventilation system that fall under the Part F regulations;


  • Background ventilators and intermittent extractor fans
  • Continuous mechanical extract (MEV)
  • Continuous mechanical supply and extract with heat recovery (MVHR)

We provide a reliable, quickly turned around service charged at competitive prices, ensuring your new domestic build properties meet all of the requirements of the Part F 2010 ventilation regulations.


Based in Maidstone, Kent, we work across the South East throughout London and the Home Counties of Buckinghamshire, Hertfordshire, Essex, Middlesex, Surrey, Berkshire and Sussex, with recent certifications carried out in Tonbridge, Ashford, Canterbury, Maidstone, Bromley, Medway, Fulham, Islington, Chelmsford, Colchester, Dartford, Milton Keynes, Portsmouth, Brighton, Lewisham, Westminster, St Albans, Croydon and the whole of London.
