UKAS and other accreditations

Every year our business is subject to scrutiny by the United Kingdom Accreditation Service (UKAS), the sole national accreditation body recognised by government to assess, against internationally agreed standards, organisations that provide certification, testing, inspection and calibration services. Accreditation by UKAS demonstrates the competence, impartiality and performance capability of these evaluators.

The BBA is pre-eminent in the construction sector and holds a unique combination of UKAS and other accreditations within the construction industry, as follows:

All BBA testing is carried out in accordance with BS EN ISO/IEC 17025.

CE Marking

CE marking is mandatory for all construction product types which are covered by a harmonised European standard. Manufacturers of such products are required to have specific properties of their product assessed by a notified test laboratory in order to achieve the CE mark.

The BBA is such a notified test laboratory for a wide variety of construction products in accordance with a range of European CE Marking standards.


We are a Registered Laboratory for Scheme Development Group 5 (‘The Keymark’) for thermal insulation products.

The Scheme is voluntary and enables manufacturers to affix the Keymark, thereby indicating a presumption of conformity with the relevant CEN standard for insulation products. It should not be confused with the regulatory CE Marking, which can also be found on thermal insulation products.

The most significant characteristic for thermal insulation products is the declared thermal conductivity. The scheme requires the use of laboratories that meet the rules for performing thermal conductivity tests to ensure a full transparency and a high level of competence and accuracy within those laboratories and to provide a consistent approach throughout Europe. Test results can only be generated from registered test laboratories that have shown to be experts in the field.

Network Rail Specification

We are a UKAS-accredited Principle Independent Test House (PITH) under the Network Rail Specification for the certification of waterproofing systems for rail bridges.
