Current statistics for air tightness tests

Just thought you might like to see what the results are looking like for the past 685 air tightness tests on new build properties. As you can see, statistically, it represents a bell shaped curve as you would expect.  My average score stays fixed at 6.35.

For more information or to book a test, call me on 01484 686649 or visit my website on http://www.hometestingyorkshire.co.uk/ I hope this helps Matt
