Residential Ventilation Assessments

Practical Ventilation Surveys for Homes

Our independent residential ventilation assessments focus on practical compliance with Building Regulations Approved Document F. We test and report on extraction and airflow performance to help you identify under-ventilation, reduce mould risks, and ensure a healthy indoor environment.

What’s Included

• Visual inspection of ventilation points, including fans, trickle vents and passive inlets
• Airflow measurement using funnel anemometer equipment
• Benchmarking results against Approved Document F recommendations
• Photographic evidence, room-by-room results, and clear reporting
• Advice on remedial options or upgrades where underperformance is found

When to Book a Ventilation Assessment

• After installing or upgrading extract fans or insulation
• Before letting or selling your property
• If you're experiencing condensation, persistent mould, or high humidity
• Following retrofits or renovations

This is a practical airflow assessment—not a formal Building Control sign-off. Our surveys are designed to help you achieve compliance, understand risks, and maintain healthy living conditions.
