As of April 2007, it is now a legal requirement that all new buildings conduct and pass an Air Tightness Test to satisfy the requirements of Part L1A.

The regulations have been put in place to reduce CO2 emissions, with the main focus being on reducing the amount of air leakage through the fabric of the new property.

The results from this test is used in the SAP calculations to ascertain as to whether you house has achieved an acceptable level.
