Air Leaking Testing Across the UK

What Does An Air Leakage Test in the UK Involve?

During an air test in the UK the pressure of the building 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. Furniture will not be affected during the test, but smaller items such as paper must be held down or removed completely so they're not blown about.

Air tests cannot be carried out if the wind speed is more than 13mph - 3 metres per second is the ideal wind speed when undertaking an air test in the UK. 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.

Employees can still do their job inside a commercial or domestic building in the UK whilst the air test is being carried out, 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.

How Many Properties Need An Air Tightness Test?

The number of tests required are as follows:

  • 4 or less properties of the same type: one test needed per type
  • More than 4 but less than 40 dwellings of a type: at least two tests of each type
  • More than 40 properties of a type: 5% of each type 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.

Why E2 Consultants?

At E2 Consultants we offer Air Testing throughout the UK and surrounding areas. Our experienced air testing consultants will also be happy to offer advice on the best ways to gain your target rating.

All new buildings in England and Wales have had a mandatory requirement since 2006 (2010 in Scotland) that domestic and commercial buildings, must have a passing air leakage certificate before the property can be passed off by building regulations.

For a quote or for more information, call our air tightness / pressure testing consultants in the UK on 0800 043 8100 or email us on @e2consultants.co.uk

E2 Consultants offer a range of services from desktop reviews of drawings to pre test inspections on site to advice on air tightness, how to improve and what needs to be completed and sealed for the testing to take place successfully.

When Should The Test Take Place?

For obvious reasons, an air pressure test is generally one of the last surveys to be undertaken once all the walls, windows, doors etc. are complete and sealed to stop any air escaping and prevent drafts through the property. The building envelope will also need to be completed.

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
