Air Testing is a recognised method of measuring the extent to which air is lost through the leaks in the building’s fabric. So essentially, you’re checking for ‘air leakage’. There are many names for this such as Air Testing, Air Leakage Testing, Air Pressure Testing, Air Permeability Testing or even just the basic Air Test. Did you know that failing to maintain air tightness can result in up to 40% heat loss? Think how much money you could potentially be wasting by ultimately heating outside!

This is especially true if you’re investing in new energy efficiency measures such as a new boiler or extra insulation. If your build isn’t air tight, or you have holes in your fabric, then this could all be pointless. Think of it this way, if you’re using a colander the water will filter through the holes; this is the same in buildings. The holes in the fabric allow for air leakage, which is not what you want. You need the fabric of your build to be air tight; Build right, build tight! The air test target is established by the design stage SAP Calculation.

Please ensure that you speak with your SAP assessor about your Air Testing Design Target. Here at ATSPACE our experienced Air Testing Engineers carry out a large number of tests on a weekly basis. So, if a failure occurs, we have the experience and knowledge to be able to identify where the leakage is coming from. If the property fails the Air Test our engineer will stay on site to help, for a reasonable time period, to rectify any minor issues. By combining your Air Test with a Ventilation Test you can save money!

As these are both compliance tests that you have to undertake it would seem mad not to. Please contact us for more information. We’re here for all of your compliance questions; big or small. We will also provide you with a FREE and EASY to read checklist to help prepare your build for the Air Test in advance. This just means that when we arrive on test day you will have been able to do all of your final checks. This is included in the service and will be sent to you in advance. The small things can really make a big difference when it comes to passing the Air Test first time.

Our fully accredited engineers have carried out air testing for over 12,000 customers, surpassing 115,000 air tests in total since ATSPACE was formed. We pride ourselves on ‘delivering beyond compliance’, we know our customers want simplicity, transparency, and a secure timeline and we are MORE THAN equipped to deliver.

Identifying air leakage prior to completion will save money and give the house-builder the knowledge needed to ensure they are fully equipped for the actual build. ATSPACE can provide pre-test assessments during various stages of the build. “If you fail to prepare, you prepare to fail.”

Our own in-house Air Pressure Testing EXPERTS will provide you with an amazing fool-proof BONUS checklist. This will be issued in advance of your Air Tightness Testing date. You can also take advantage of our knowledge bank, complete with our own videos, advice, and checklists. It’s all FREE!

Air Leakage Testing is one of the biggest building compliance tests we deal with here at ATSPACE, aka Air Tightness Testing, Air Permeability Testing, etc. I am an accredited iATS level 2 Air Tester, and I was involved with the FIRST commercial care home that reached Passive House Standards. The outcome was a complete success. I immersed myself in the whole process, from the design stage through to the test completion.

ATSPACE is the UK's leading compliance company. The continued, unprecedented support from both new and existing clients is the driving force behind ATSPACE’s success and determination.

Residential Air Testing - Questions Answered

What are the Best Ways to Find Air Leaks?

First of all, to carry out an air pressure test on your property we will ideally depressurise it. This will highlight any leakage points.

How Long Does an Air Test Take?

The Air test itself will probably take between 45 minutes and an hour, assuming it’s straight forward. This will also include measuring up the property and diagnostics.

How Can ATSPACE Help with my Air Test?

Here at ATSPACE we are passionate about you, our clients, we have engineers in the north, south, east, and west of the UK and their main roles are to carry out air tests on site. If you have a failure, they will diagnose any leakage area in the form of a video.
