Air Tightness Testing Services
Helping our customers to meet part L1a of the Building Regulations
What we do
Provision of air tightness Testing Services
We carry out air tightness tests on new build dwellings and small commercial buildings.
Our role is to attend site to carry out a fan pressure test and provide you with certification that the dwelling has achieved the stated Air Permeability.
The result of the test feeds into the SAP calculation that new build dwellings require, helping you to satisfy Part L1a of the building regulations.
The result is used by your energy assessor to finalise the “as built” SAP calculation.
