Ventilation has moved from a minor compliance footnote to a major enforcement priority. The tragic death of Awaab Ishak — caused by prolonged exposure to mould in a poorly ventilated social housing property — led to sweeping changes in how housing providers approach damp, mould, and indoor air quality. For landlords in Manchester and Stockport, understanding Building Regulations Part F and the ventilation testing requirements is now essential.
What Is Building Regulations Part F?
Approved Document F of the Building Regulations sets out the ventilation requirements for all buildings in England. For residential properties, the key requirements include:
- Whole-building ventilation — a minimum background rate of fresh air must be provided throughout the property
- Extract ventilation — kitchens, bathrooms, and utility rooms must have adequate extract fans capable of removing moisture and odours
- Purge ventilation — windows or other openings must be capable of providing rapid ventilation when required
- Mechanical ventilation systems must be commissioned and balanced to ensure correct airflow rates
Since June 2022, Building Regulations Part F has been updated with stricter requirements for new-build properties and major renovations. However, existing properties are also coming under increased scrutiny from housing ombudsmen and local authority enforcement teams.
Why Ventilation Testing Matters for Landlords
Poor ventilation is the leading cause of damp and mould in residential properties. Damp and mould are now classified as Category 1 hazards under the Housing Health and Safety Rating System (HHSRS), which means local authorities can take enforcement action against landlords who fail to address them. In the wake of the Awaab Ishak case, the Regulator of Social Housing and the Housing Ombudsman have both issued strong guidance requiring landlords to take a proactive approach to ventilation and indoor air quality.
For private landlords, the risks are equally significant. Tenant complaints about damp and mould are increasingly leading to council inspections, Improvement Notices, and civil penalties. A comprehensive ventilation assessment can help you identify and address ventilation issues before they escalate into enforcement action.
What Does Ventilation Testing Involve?
Our ventilation testing service measures the actual performance of your property\'s ventilation systems against the requirements of Approved Document F. The process includes:
- Airflow rate testing of all extract fans (kitchens, bathrooms, utility rooms)
- Whole-building ventilation assessment using calibrated airflow meters
- Ductwork inspection and condition assessment
- Trickle vent checking and measurement
- Moisture and humidity monitoring
- Identification of underperforming or incorrectly installed systems
- Full written report with recommendations for improvement
