Air Leaking Testing Across the UK

Do I Need An Air Leakage Test?

Part L of the Government building regulations explains that on a large plot of new houses that are built to a similar specification, only a sample of the houses will need to be air tested.

All new buildings in England and Wales have had a mandatory requirement since 2006 (2010 in Scotland) that domestic and commercial buildings, over a certain size, must have a passing air leakage certificate before the property can be sold.

Planning your test in advance will help our experience air assessment team covering the UK to determine how many tests you'll need ahead of time per property and will be happy to offer advice on the best ways to gain your air permeability rating.

How Many Properties Need An Air Tightness Test?

If you have 4 or less properties of the same type then only one test needs to be undertaken per type. If you have more than 4 but less than 40 dwellings of a type then you need at least two tests to be done on each type. Finally, if there are more than 40 properties of a particular type then at least 5% of each type needs to be tested UNLESS the first 5 get a passing score - then this can be dropped to just 2%.

What Air Permeability Rating Do I Need?

A passing score in the UK is 10 m³/(h.m²) for an air permeability rating which resembles the amount of uncontrolled air that's leaking from the dwelling. Should the test fail, our air tightness team will help you identify where the leakages are happening in the hope that a passing score will be achieved after a re-test.

When Should The Test Take Place?

A building envelope will need to be completed before the air test takes place - which should be one of the last surveys undertaken once all the walls, windows, doors etc. are complete and sealed. This ensures no air will escape and prevent drafts through the property which will in-turn improve your air permeability score.

What Does An Air Leakage Test Involve?

An air test involves placing a large fan, or several fans, to an opening within the property; usually a doorway. The fans will increase and decrease in speed that will in-turn change the building's air pressure and record the results. Please note: an air test cannot be carried out if wind speed is more than 13mph. 3 metres per second is the ideal wind speed when undertaking an air test in the UK.

Employees can still do their job inside a commercial building in the UK, within reason, though may feel some discomfort due to the noise of the fan and the draught that will be felt throughout the building. There should be no outside access once the test has begun - which lasts for approximately 90 minutes, so plan accordingly.

Whilst the air tightness test is being undertaken, furniture will not be affected but smaller items such as paper must be held down or removed completely so they're not blown about. The pressure of the room will be tested and as such all windows and doors that lead outside must be securely closed to avoid them swinging open and the test being abandoned. Similarly, all internal doors should be wedged open to avoid being slammed shut.

Today takes 2 of our engineers, air testing this enormous modular classroom in Tring, It took 4 fans to test this space and unfortunately resulted in a Fail. Remedial sealing will be required to areas that we have identified as leaking cold air infiltration. #preperationiskey
