Why become an Airtightness Tester?
Airtightness Testers are highly skilled professionals who assess the airtightness of new build properties. It’s an incredibly rewarding job where no day is the same, and puts your problem solving skills to the test!
Required by all new build properties
An update to part L standards in Building Regulations on 15th June 2022 now means that every new build property requires an airtightness test, presenting a huge opportunity for those looking to get involved in this area of the industry.
Join a rewarding profession
The airtightness test is usually one of the last assessments a property will undergo before it can be signed off by Building Control. This crucial last step makes the airtightness tester a key part of the process, where they will work with the building owner to ensure the building meets compliance.

What's involved in airtightness testing?
As an airtightness tester you will measure new build properties’ airtightness levels using Pulse or blower door equipment. The method of carrying out the test will differ depending on which equipment you use, however in both instances you will produce a test certificate which you can present to the builder or SAP assessor.
