What is a Legionella control programme?

A Legionella control programme is the ongoing management regime that puts your risk assessment into action and keeps it there. It brings together monitoring, sampling, inspections, maintenance and record-keeping under a single written scheme of control, ensuring that identified risks are managed continuously rather than assessed and forgotten.

We design and deliver control programmes tailored to your systems, sector and risk profile, in line with ACoP L8 and HSG274. From appointing responsible persons and defining tasks to managing schedules, records and reviews, we provide the structure and specialist support that turns a risk assessment into demonstrable, day-to-day compliance.
