Air Testing & Leakage
Our engineers use Thermal camera and extensive knowledge of buildings to help find leakage areas within the building and can advice of these.

Air Testing is sometimes referred to as Domestic Air pressure tests, Domestic Air tightness tests, Domestic Air tests, Domestic Air pressure testing, Domestic Air tightness testing, Domestic Air leakage testing.
Air Leaking Testing Across the UK
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.
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 Does An Air Leakage Test in the UK Involve?
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.
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 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.
Why E2 Consultants?
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.

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.
At E2 Consultants we offer Air Pressure Testing throughout the UK and surrounding areas. Our experienced air pressure testing consultants will also be happy to offer advice on the best ways to gain your target rating.
What Air Permeability Rating Do I Need?
Your air permeability rating resembles the amount of uncontrolled air that's leaking from the dwelling. A passing score in the UK is 10 m³/(h.m²). If the air test fails, we will help you identify where these leakage areas occur in the hope that a passing rate will be achieved following a re-test. The final target will be set by the design SAP Calculation (please contact us if you require one of these in the UK )
