About Us


Air Leakage Testing Ltd has been providing testing services to the construction industry since 2002.

Over the years we have expanded our range of testing and improved our equipment and approach to keep pace with industry developments. Most recently becoming UKAS accredited for acoustic testing.

In December 2017, Air Leakage Testing Ltd was purchased by Tom Gregory, Scott Bartholomew and Stephen Hayden who have more than 30 years’ combined experience of air tightness and sound insulation testing in their own right.

The combined knowledge and resources makes Air Leakage Testing Ltd one of the most experienced testing organisations in the country but we haven’t lost the personal touch and focus on customer service.
