British Board of Agrément

The BBA is concerned with testing, assessment and certification of productions of the construction industry, to secure the ready acceptance of the products concerned and to ensure their safe and effective use. Subjects for assessment are normally new or innovatory products; existing products may be assessed, for example, as a result of changes in Building Regulations requirements. Brief details of certificates issued are given here; in every case it should be checked with the BBA how a product complies with the relevant requirements of the Building Regulations 1985 (England and Wales), the Building Standards (Scotland) Regulations 1981 to 1984 and the Building Regulations (Northern Ireland) 1977 (as amended) which are given in the certificate, as well as the technical specifications and conditions for use. It is advisable to check that certificates have not been withdrawn or superseded by a later issue, either by referring to the Index of Current BBA Publications or contacting the Board direct (Telephone Hotline 01923 662900). The address of the Board is PO Box 195, Bucknalls Lane, Garston, Watford, Hertfordshire WD2 7NG. Tel: 01923 670844; Fax 01923 662133.
