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.

Reverberation Time
The reverberation time of a room is defined as the time it takes for sound to decay by 60 dB after an abrupt termination...more
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?
The air leakage should be completed once the building is completed. All doors and windows in place, all skirting boards sealed, traps filled with water and any penetrations through the envelope of the building need to be sealed. Please find checklist within the downloads section of the website which provide a comprehensive list of requirements. People who follow this checklist have a much higher change of passing the air test first time.
What Does An Air Leakage Test in the UK Involve?
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.
There should be no outside access once the test has begun for approximately 90 minutes so plan accordingly. Workers can still do their job inside the property, within reason, though may feel some discomfort due to the noise of the fan and the draught that will be felt throughout the building.
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.

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 Leakage Testing throughout the UK and surrounding areas. Our experienced air leakage testing consultants will also be happy to offer advice on the best ways to gain your target rating.
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?
The air tightness rating of a property is not a fixed figure. This is set by the design SAP Calculation carried out (please contact us if you also require a SAP Calculation in the UK ). However the worst acceptable standard for air tightness is 10 m³/(h.m²) which resembles the amount of uncontrolled air that's leaking from the dwelling. However this does not mean that it would pass the SAP Calculations Design Air Permeability standard. 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.
