Your building needs a legionella assessment. Here's how to get it done.

Choose the route that fits your building. Full training is the complete duty-holder path. Small business is the shorter route for lower-complexity premises.

Complete route 19 modules

Full duty-holder training

For landlords, responsible persons, assessors, and anyone who needs the whole chain: organism, aerosol route, building risk, control, monitoring, records, and response.

Best when the system is more involved, the building is mixed-use, or you need the defensible complete route.
Start full training

No account needed to begin.

Small business Scoped route

Small business training

For lower-complexity premises with simpler domestic-style systems, where the real need is clear controls, clear boundaries, and clear escalation points.

Use this for cafés, salons, studios, and small offices. If you have stored water, complex hot-water distribution, unusual plant, or higher-risk occupants, take the full route instead.
Start small business training

Shorter course. Narrower promise.
