Legionella Testing & Water Sampling for Cardiff properties
Sampling is not a substitute for good temperature control, but it is an important check in higher-risk settings, after remedial work, after a positive result or where temperatures cannot be maintained. We take samples to the relevant British Standard and use UKAS-accredited laboratories for analysis.
Sampling in Cardiff is most often needed in healthcare and care settings, hotels with spa pools, sites with cooling systems and after remedial works. Samples are collected to BS 7592 and sent to UKAS-accredited laboratories, with results explained against HSG274 action levels.
Cardiff's purpose-built student housing, city-centre offices and stadium-area hospitality venues all have periods of low use, from university holidays to event-day peaks, which affect how water systems need managing.

Legislation in Wales
In Wales, the same health and safety framework applies as in England: the Health and Safety at Work etc. Act 1974, COSHH 2002 and HSE's ACoP L8 and HSG274.
In Cardiff, legionella law is enforced by Cardiff Council's environmental health team for offices, shops, hotels, restaurants and leisure premises, and by HSE for factories, warehouses, hospitals, schools and council-run premises. We cover all CF postcodes in and around Cardiff.
