Legionella Testing & Water Sampling for Belfast 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 Belfast 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.
Belfast's mix of Victorian terraces, Titanic Quarter offices and apartments, hotels and healthcare sites are managed under Northern Ireland's health and safety framework, with HSENI as the enforcing authority for many workplaces.
