BS 8000-14 (workmanship)

BS 8000-14 is a British Standard giving recommendations for workmanship in the installation of below-ground foul and surface water drainage on site. The standard supports the design provisions of BS EN 752 and BS EN 1610 by setting out practical site requirements including handling, storage, jointing, testing and reinstatement. It is regularly referenced in UK contract specifications and in Sewers for Adoption design codes used by Thames Water for s.104 agreements across Greater London. Practical implications for contractors include having a clear and verifiable framework for site quality, supporting Building Control inspection and adoption sign-off. The standard is also useful when investigating disputed work, providing an objective benchmark for what constitutes competent installation. The formal reference is BS 8000-14:2011, regularly read alongside BS EN 752 and the relevant Approved Documents.
