PRESS RELEASE – 1 December 2015


Changes in the UK Air Tightness Testing Industry

iATS and ATTMA to replace BINDT as CPS Scheme Operators

31 December 2015 sees the end after many years, of the British Institute of Non Destructive Testing’s (BINDT) involvement in Air Tightness Testing in the UK.

There has been a dwindling number of BINDT registered testers during 2015, and from 1 January 2016 there will be no BINDT registered testers, and BINDT Air Permeability Certificates will no longer be valid.

In place of BINDT, DCLG has approved two schemes to run Air Tightness Testing Competent Persons (CPS) Schemes in the UK: –

iATS – the Independent Airtightness Testing Scheme (; and
ATTMA – The Air Tightness Testing and Measurement Association (

Both schemes can register and assess testers to all three levels of testing, and both provide Air Permeability Certification to comply with s43 in England, and equivalent regulation elsewhere.

Among other changes, the new Conditions of Authorisation require the Schemes to undertake a higher standard of oversight of testers and their companies than previously.

For more information, please contact Arran Cothill, Scheme Manager at iATS on 0300 688 0016
