Air tightness testing – dwellings
Approved document L1A confirms that requirement for air tightness testing for at least a percentage of all new dwellings, most developers opt to test 100%.
Since most testing is required very near to completion/handover , time is of the essence. Our support staff work very closely with our clients’ site management teams to remove the risk of costly delays.
A result is available immediately after the test is carried out and certificates can be issued within 24 hours.
Testing is carried out to ATTMA (Air Tightness Testing & Measuring Association) standards and we are UKAS accredited for this service.
We also provide ventilation flow rates in accordance with Approved Document F.
