Spa pools are known by a variety of names including hot spa, hot tubs, whirlpool spa and portable spa.. They are a recognised source of Legionnaires' disease and are subject to health and safety laws requiring managers, designers, manufacturers and installers to ensure spa pools remain safe.
HSE and Public Health England have published guidance on Management of Spa Pools - Controlling the Risks of Infection . It is aimed at dutyholders, particularly those designing, manufacturing, supplying, installing, displaying and managing spa pools to help meet their legal responsibilities and explains how to manage and control the risk from legionella in spa pools.
This guidance is currently under review.
