BS 8558:2015

BS 8558:2015 was developed to provide complementary guidance to the BS EN 806 suite of standards. Together, these documents provide best practice for the design, installation, alteration, testing, operation and maintenance of hot and cold water services for domestic use in buildings.

Who is this standard for?

• Anyone involved in the design, installation, testing, operation and maintenance of services
• Water companies
• Product manufacturers
• Installers of water supply services in the UK

Organisations with an interest in water supply services in the UK and organisations referring to BS 6700 would also benefit from referencing BS 8558.

Why should you use this standard?

BS 8558:2015 bridges the gap in the BS EN 806 suite of standards and the withdrawn BS 6700. It provides UK guidelines for the water supply services industry on all aspects of sampling and monitoring of hot and cold water services. It also gives guidance on underground pipework within the curtilage of a building.
