“How Does ATSPACE Achieve A 97% Pass Rate For 

Ventilation Flow Rate Testing?

Meet Building Regulation Sign Off FAST

Vent testing is the commonly used, industry generic term when referring to either Part F test requirements or ventilation testing of all of the extraction systems within your building.  

So “vent testing” is a key part of any build and is essential to get building control sign off.

Vent testing looks at two elements of your build to satisfy that there is an adequate means of ventilation for your building and that all fixed systems installed are both commissioned and fit for purpose. Extraction systems must meet a measurement of air, often called the ventilation flow rate. If the measurement is not correct or the units used are not built for purpose then building control will not sign off your build as complete.                     

Failure to meet the correct flow rate for vent testing could mean a complete replacement of your extraction systems including changes to the fabric of your build too, so rather than wait until you have completed your build you should consider ventilation as part of your design stage and review, especially for commercial build projects.

Alternatively, when you commission our services for air testing then why not combine that service with vent testing as both go hand in hand and could save you money by only having one site visit, rather than two separate appointments and costs.

To assist you further we also provide an easy to read checklist to help prepare your build for vent testing in advance of us turning up.  It is included within the service and is sent in advance of the date that is booked for your testing to assist you as small things can make a big difference when it comes to passing first time, every time
