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.


We pride ourselves on being competitively priced on all our services, so if you find a cheaper quote for the same thing from someone else, we will beat it.

Projects are quoted on an individual basis but the following is designed to provide an indication of typical prices:

  • Air test on a single house – £150-£200, depending upon location and size
  • Air or sound testing on multiple dwellings on the same visit – £40-50 per test, depending upon the type of plot and number of tests per visit (this is based on a minimum number of tests per visit, typically 5 or 6 tests)
  • Air test on a simple, small, commercial building (e.g. an industrial unit with a footprint of 500m2) – £295-£395 (we may be able to test multiple units on the same visit which would further reduce the costs)
  • Air test on larger, more complex, commercial building (e.g. a school building with a footprint of 1,000m2) – £495-£595
