Ventilation Flow Rate Testing is part of the Building Regulations and refers to Part F. Vent Testing, or Extractor Fan Testing, is a way of testing to ensure your ventilation system(s) are working properly and fit for use.

As stated above, there are many abbreviations for these services, including Ventilation Testing, Extractor Fan Testing, Extract Testing, Smoke Vent Testing, Ventilation Test, and the basic go to Vent Test.

With Ventilation Testing, you will need to ensure your build has the adequate air tightness. You can do this by booking an Air Leakage Test; these two compliances go together. By ensuring your ventilation systems are correct and fit for purpose, you provide a healthy living environment within your home. ATSPACE can offer compliance testing for all your regulations, so please do not hesitate to ask. We are your one-stop-shop for your building compliance.

The correct ventilation in your property will eradicate moisture from your build. If it builds up, this moisture will cause mould, mildew, and bad smells (among other issues). Buildings these days are becoming more energy efficient with better air tightness strategies put in place, but by doing that you limit your ventilation, therefore it's key to understand the requirements and the correct system is used.

There are 3 systems which require a flow rate test to, these include:

1. Ventilation Flow Rate Test - System 1 (Intermittent Extract Fans)

2. Ventilation Flow Rate Test- System 3 (Continuous - Centralised or Decentralised)

3. Ventilation Flow Rate Test MVHR - System 4

Here at ATSPACE, we pride ourselves on our ability to know how to get the best from an Extractor Fan Test. The extract rate in which your build disperses water vapour is important, vital even. To get the most from your Extractor Fan Test, it is always best to speak to a compliance engineer at the earliest possible stage to understand the different requirements for the wet rooms, which have different flow rates required.

Our one stop approach will save you money by combining our other services with a single visit. All our engineers are fully conversant in all ventilation flow rate testing, air pressure testing, sound insulation testing, passive house air pressure testing and much more.

Free ventilation checklist is available when you are ready to prepare for your vent flow rate test. Any concerns or questions, please call.

Our engineers have conducted Vent Testing for over 6700 customers and have a record of 91% first time pass rate. We know our clients want “uncomplicated compliance” and we strive to deliver just that.

Our Amazing Engineers team is fully conversant in all the different ventilation testing systems. With this knowledge, it makes it easier to have a team who knows what they are talking about when it comes to your vent test.

Ventilation Flow Rate - Questions Answered

Why Does My System 1 Fail? 

System 1 are the intermittent fans which come on and off in your bathroom. You need to make sure that you have the correct fan fitted and take a look at the ductwork!

Why Do I Need a Ventilation Test? 

You need to meet Part F of the building Regulations! With more air tight homes being built, you need to ensure that you have the required ventilation.

What Stage Do I Need a Ventilation Test? 

If you’re looking for advice, you should get it as early as possible. However, ventilation is usually tested when the build is completed. This doesn’t mean it can’t actually be tested at any stage!
