Why Background Ventilation Testing Matters in Ealing

With new housing regulations now in effect, Ealing Council requires all HMO properties to undergo background ventilation testing in accordance with CIBSE TM23 and the Insulation Assurance Authority (IAA) guidance.

This is now a mandatory requirement for all HMO licence renewals and new applications in Ealing.

Background ventilation testing ensures your property maintains adequate airflow, prevents condensation and damp, and promotes a healthy indoor environment for tenants. Meeting these ventilation standards is essential for HMO compliance, plus a recent Background Ventilation report helps expedite the journey through the HMO licence application process.

At Airtite, we provide certified background ventilation testing specifically tailored for HMO landlords across Ealing Borough. Our qualified technicians carry out CIBSE TM23 testing efficiently and provide clear certification so you can achieve Ealing Council HMO sign-off quickly and confidently.

Whether you’re renewing an HMO licence or submitting a new application, Airtite ensures your application addresses all required ventilation compliance standards, with professional service, fast turnaround, and expert guidance at every step.

Our comprehensive background ventilation testing service in Ealing covers every requirement set out by Ealing Council under CIBSE TM23 and Insulation Assurance Authority guidance.

Each inspection and report includes:

  • Whole House Ventilation Rate – assessment of total airflow performance throughout the property.

  • Background Ventilation Equivalent Areas – measurement of vent size, type, and location to ensure compliance.

  • Air Permeability Testing – comparison of actual versus design values for each bedroom and the overall dwelling.

  • Purge Ventilation Provision – verification of window and vent sizes, types, and placement in every room.

  • Door Undercut Measurements – ensuring correct air transfer between rooms for balanced ventilation.

  • Extractor Fan and Cooker Hood Flow Rate Testing – confirming correct airflow rates to meet building regulations and HMO standards.

All testing results are compiled into a comprehensive compliance report, ready for submission to Ealing Borough Council.
