Air tightness or pressure testing is a skilled method of determining uncontrolled airflow, air leakage and unwanted drafts at a property which may result in heat loss. As such, a property would not be deemed environmentally friendly and could prove expensive to run.
🍃 In accordance with Part L of the Building Regulations, it is essential to perform air tightness testing on all new residential or commercial builds before completion. This process verifies the building’s air tightness, a crucial factor for sustainable developments.
🔍 Our Expertise:
Our team of skilled air tightness engineers conduct meticulous testing using fully calibrated and certified kit, collaborating closely with the on-site team. We not only identify any issues but also offer guidance and advice, ensuring the highest level of air tightness is achieved and therefore enhancing energy efficiency.
Eco Technology are Air Tightness Testing Measurement Association (ATTMA) registered members, working on some of the UK’s flagship projects, you can have confidence in Eco technology’s equipment, technicians, consultants .
At Eco Technology, our focus is on providing precise, reliable, and comprehensive air tightness testing services across a diverse range of building types. We are dedicated to enhancing the energy efficiency and overall quality of structures while working closely with clients to achieve exceptional results.
Reporting & lodging the result
📋 Comprehensive Reports:
Upon completion, detailed reports encompassing the test results are issued. These reports offer valuable insights into the property’s air tightness and helping you maintain compliance.
Initially the air test data is checked on site and then verified by office team, prior to the final result being calculated.
Then, the client is sent an electronic PDF version of the final air test report and the result is lodged on the ATTMA web site.
We pride ourselves in ensuring clients receive their results in a timely manner, many sites and projects are on a timescale to ensure CML sign off.

How long does it take?
Most air tests to domestic units and simple commercial units are carried out in 30 – 45 minutes which may be extended if the test fails and leakage paths are investigated with smoke.
Re-tests can be carried out at no extra charge if completed within the allowed time.
If complicated or very large buildings are being air tested with multiple fan units, allow up to 4 hours for the test and longer if smoke investigations are required
How to prepare for an air tightness test?
In essence, an air test is one of the final tasks in the construction process. By the time the test is conducted, the property or building should be fully assembled, with all windows, doors, skirting boards, architraves, and lighting fixtures installed. Additionally, all necessary sealing work should be accomplished, ensuring the structure is in its completed state before undergoing the air testing procedure.
There are several main key leakage areas within a new build dwelling, conversion or extension. see video below showing the areas and what to do to to improve the air tightness.
We have a checklist template available detailing all elements which are essential before an air test is carried out, please get in touch for more information.
