Domestic ventilation testing is required by Part F Building Regulations 2010 to verify that all ventilation systems in new domestic dwellings are fully compliant with building regulation targets. Ventilation testing is carried out by measuring airflow rates on all mechanical ventilation, including everything from intermittently used extract fans and cooker hoods to continuously running systems.
Build Check offer a quick and cost-effective domestic ventilation testing service nationwide, which can take place alongside Part L air tightness testing and/or acoustic testing to reduce site disruption. All Build Check tests are carried out by BPEC qualified engineers.
Tests are required for three types* of ventilation systems, as described in Part F:
System 1 – Background ventilators and intermittent extract fans
System 3 – Continuous mechanical extract (MEV)
System 4 – Continuous mechanical supply and extract with heat recovery (MVHR).
* Testing is not required for System 2 – Passive stack ventilation (PSV).
