We test domestic and commercial buildings to comply with L1 & L2 regulations.
Air Leakage Testing Ltd are UKAS accredited testers of all types of building. We can test both Domestic and Commercial properties for air leakage, air tightness and air permeability. Our accreditation for air testing is to ATTMA technical standard 1 (2006) BS EN 13829:2001 and ISO/IEC 17205 (testing).
 We offer total UK coverage for domestic and commericial buildings from 4 convenient locations. This includes the whole of Scotland from our York office. See larger Map here.
And what is Air Leakage Testing?
From the 1st April 2006 Part L of the new buildings Regulations has been completely revised. All buildings with a gross floor area of 500m2 and above now require a mandatory air permeability test. This is for buildings that are NOT dwellings.
For dwellings L2 requires a representative sample of dwellings being built to be tested.
Air Permeability explained.
The air-tightness of a building is known as its 'air permeability' or leakage rate. Air leakage can occur through gaps, holes or cracks in the fabric of the building envelope which are not necessarily visible to the naked eye. This air leakage affects the building's performance and is now firmly enshrined in Part L of The Building Regulations - conservation of fuel and power. Air tightness testing and air permeability testing will highlight any problems with air leakage so they can be remedied.
