Air Tightness & Pressure Testing

Under Part L1A of the Building Regulations, Air Testing is a mandatory requirement for all newly built homes.

ERS have the tools and experienced consultants to support you in passing the air tightness and pressure testing requirements and completing any remedial work if required to ensure compliance.

Minimising air leakage plays a key role in reducing carbon emissions. By reducing this, the costs of fuel bills can be decreased significantly.

Conducting and Passing Air Testing

To carry out Air Testing, we use a door blower fan system and other UKAS calibrated equipment to provide the Air Permeability Rating. We carry out the test in accordance with the procedures detailed in ATTMA TS1 and BS EN:13829 (2001).

In order to pass the Air Test, the Air Permeability must be less than or equivalent to the Design Air Permeability.

 Before a test, the following should be considered:

An air tight barrier should be formed by each of the surfaces in the room, including the walls, ceilings and floor. The property must be fully decorated and ready to move into at the point of the testing. It is advisable to have a skilled site worker available at the time of the test so any remedial work can be completed straight away if required to achieve a ‘pass’ result.

ERS will support you through the Air Testing process and ensure that with our advice, you achieve a ‘pass’ result and reduce leakage where necessary thereby increasing the energy efficiency of your buildings.
