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

How We Test & Analyse Airflow

Set-up: We log humidity and temperature readings to understand background conditions before testing each extract point.
Testing: Calibrated funnel anemometers measure airflow volumes, while smoke pencils highlight dead spots or back-draughts.
Diagnosis: Results are compared with Approved Document F targets and the property’s occupancy patterns to determine where improvements are necessary.

Where safe access allows, we inspect loft ducting, roof terminals and trickle vents to identify blockages or poor installations. You’ll know whether issues stem from fan performance, duct layout, or everyday usage habits.

Reporting & Ongoing Support

You receive a concise summary within 24 hours followed by a detailed report. This includes colour-coded airflow tables, photographs, and tailored recommendations. We outline quick wins such as cleaning grilles or adjusting settings, alongside longer-term upgrades like continuous running fans or heat-recovery systems.

Need to evidence compliance for letting agents or contractors? We can provide follow-up letters or revisit after remedial works to verify that improvements have achieved the desired airflow rates.

Frequently Asked Questions

Curious about the process? These FAQs cover what clients usually ask before booking.

What equipment do you use during a ventilation assessment?

We arrive with calibrated funnel anemometers, hygrometers and data loggers to capture airflow volumes and environmental conditions. The results are documented room-by-room with supporting photographs.

Will the visit disrupt my tenants or household?

Disruption is minimal. Each room takes only a few minutes to test and we work around occupants wherever possible. Access is needed to fans, trickle vents and any loft hatches.

Does the assessment provide Building Control sign-off?

The survey is advisory and does not replace Building Control certification. It does give you evidence of airflow performance and a clear action plan to achieve compliance if required.

Can you recommend improvements if airflow is poor?

Absolutely. We suggest suitable upgrades, from boost controls to new continuous running fans, and highlight maintenance tasks to keep systems operating efficiently.

How quickly will I receive the results?

You receive an initial summary within 24 hours, with the full report delivered in three to four working days. Urgent risks are flagged by phone straight away.
