Air Pressure Testing 

UKBC are registered and accredited to undertake both Residential and Commercial Air Tightness Testing with ATTMA.

Air Pressure Testing - What You Need To Know 


Air Pressure Testing – also known as Air Tightness Testing or Air Permeability Tests – measures how much air is escaping from a building.

When you’re undertaking a new residential or commercial development, you’ll need to make sure there isn’t too much ‘air leakage’. Air leakage is when air escapes through the fabric of the building via uncontrolled means. This could be through gaps around windows, sockets, or where the external wall meets the floor.

Air Permeability Test with UKBC


UKBC offers ATTMA accredited Air Permeability Tests for residential and commercial buildings. Our service includes:
  • Pre–test site inspection, undertaken at various stages during the building’s construction.
  • Thermographic surveys and smoke testing, to determine key leakage paths.
  • A review of design or construction drawings to identify potential building leakage paths.
  • Induction seminars and on-site training for the construction team.

Air escaping can cause cold draughts and heat loss. Improving the air tightness of a building will lower your heating bills and improve the energy efficiency of your property. You are required by law to make sure your development is sufficiently airtight, therefore, it’s important to be confident that your building meets the required regulations. Air tightness testing is required by Part L1A and L2A (England & Wales), Section 6 (Scotland) or Part F1 (Northern Ireland) of The Building Regulations. Air permeability testing has been mandatory for all new build residential and commercial properties in England, Wales and Northern Ireland since 2006, and in Scotland since 2010.  You should carry out Testing when your project is near completion. This is so you can make sure the building meets or exceeds the air permeability rating specified in your design stage SAP or SBEM Calculations.
