Ventilation Flow Rate Testing

Does my development need a Ventilation Flow Rate Test?

The Building Regulations Part F requires residential dwellings, flats, houses or rooms for residential purpose (HMOs, hotel rooms etc) to achieve minimum levels of ventilation flow rates.

Commissioning a ventilation flow rate test can demonstrate compliance. Winthorpe Management Services can help your project achieve compliance – talk to our team today to find out how our tests can help.

Our team can provide

Ventilation Flow Rate Testing – Intermittent extractor fans with background ventilators (System 1).

Our Ventilation Flow Rate Testing service focuses on assessing the effectiveness and performance of intermittent extractor fans combined with background ventilators, commonly referred to as “System 1” in building ventilation systems. This specialized service is designed to ensure that residential and commercial properties maintain a healthy and comfortable indoor environment by efficiently exchanging stale indoor air with fresh outdoor air.

How to pass the Ventilation Flow Rate Test

The extract rates vary on the room usage and where the extractor unit is set intermittently or continually.

The key points are:

Required extract rate
Factors creating resistance to effecting Air flow rates
Length of ducting
Type of ducting used e.g. rigid or flexible. Note: flexible ducting should be kept to an absolute minimum - see our Ventilation Flow Rate 'Do's and Don’ts Guide

Seek professional advice; the fan manufacturer should be able to recommend a fan from their range, taking the resistance factors specific to your site into consideration.

Once you have this information, please get in touch with our team and we can begin scheduling a ventilation flow rate test.

The Process

We need the basic details of your project together with the approximate test date e.g. 2 new build houses in NW16, ready in 2 weeks
Either call our admin office 0208 0921 225, email info@wms.ltd or use the Contact Us Form
You will be allocated a dedicated account manager for the duration of the project.
We usually provide the quote that working day
The Ventilation Flow Rate Testing Checklist helps you to ensure the extractor units are ready for testing.
On the test day, the test engineer will provide an immediate result.
The test certificate/s are guaranteed to be provided the next working day, or on the day of testing if agreed in advance.
Send the certificate/s to Building Control as part of the required Completion Documentation

What happens if the testing does not achieve required target?

If the required level has not been achieved, our team of acoustic experts and engineers have the knowledge and experience to advise you on what is required to resolve the issues you may be facing.
