Part L1A regulations require an Air Leakage Test

Air leakage can occur at many places in buildings. Heating bills rise, while performance and sustainability fall. It’s an unneeded waste when airtight homes use less energy for heating, put cash in owners’ pockets and pump less CO2 into the environment.

Part L1A of the Building Regulations requires new homes to pass an Air Leakage Test.  The Test measures air permeability – highlighting unwanted drafts and uncontrolled airflow through a building. Controlling air leakage is a key factor in achieving energy efficiency and in meeting the Building Regulations.

Ultimately, all six surfaces of the external shell (floor, ceiling, walls) must provide an air tight barrier against air leakage to a standard of 10 m³/ (h.m²) at 50 Pa (the average across a site, however, must be 8 m³/ (h.m²) or lower).

An air leakage test demonstrates to building control officers that each dwelling design complies with Part L.
