How long does typical domestic Air tightness Test take?
It depends on the size of the property, how many apertures need to be taped over and if you are able to provide a full set of plans (preferably in an electronic format). The duration of the actual test should take no longer than 2 hours. If the property passes the Air tightness test a certificate will be issued which should be passed to the Building Control Body within 7 days of the test being carried out.
