The Air Tightness Testing & Measurement Association is a DCLG-appointed Competent Persons Scheme for air-tightness testing.
The Air Tightness Testing and Measurement Association (ATTMA) is a professional association dedicated to promoting technical excellence and commercial effectiveness in all air tightness testing and air leakage measurement applications. It was formed in 2002 to promote the testing and measurement industry and supports its members by extending market awareness of the technology and the members’ services.
In January 2015, ATTMA became a Competent Persons Scheme for the air tightness testing industry, replacing the BINDT.
ATTMA is a proud organisation with 15 years of history, releasing technical support documents, guidance leaflets and are even responsible for the ATTMA Technical Standards, used not only in English and Welsh Building Regulations, but are used or referenced in over 90 countries.

Why Choose an ATTMA Member?
• Individually auditing our members on-site – by visiting every single tester in the scheme, we check not just paperwork, but the entire testing process. We see everything including, but not limited to: Quoting, contracting, testing method, report, calibration, condition of the testing kit, quality control measures, the test reporting process and much more. This gives the end user confidence that, in order to get that ATTMA certificate, the above process has been followed.
• Auditing in accordance with ISO 19011 – Our auditors are trained to audit in accordance with ISO 19011 and ISO 9001 – promoting a uniform audit no matter who the company are.
• Lodgement – Our lodgement system is ever evolving. We have worked with the equipment manufacturers for over a year to implement ATTMA Lodgement – a process of lodging data and allowing a fairer way to fund the scheme as well as the ATTMA uniform certificate which all members produce, making it clear whether or not a test has truly passed.
