Schedule of Accreditation 0357: British Board of Agrement
Retained issue 054, dated 29 March 2024, identifies the Bucknalls Lane laboratory, contact route and selected accredited construction-product testing. BBA’s current contact page states its accreditations are temporarily suspended, so the schedule is not presented as proof of current accredited status.
The current contact page states that BBA accreditations are temporarily suspended and says BBA is working with UKAS. It does not establish when or whether the suspension will be resolved.
The current BBA testing page presents Test Services for product and system capabilities. It does not identify individual accredited methods or override the current accreditation-suspension notice.
