This is a curated record of significant, well-documented cases, not a complete list of every prosecution in the sector, and it skews towards fatal and heavily reported cases. Cases with no fine (a conditional discharge, for example) count as prosecutions but add nothing to the fines total. The full record, the curation rules and the correction policy are on the Legionella Enforcement Tracker.
Past prosecutions show what courts have punished; they say nothing about any individual building. The failings that recur in these cases - no risk assessment, no written scheme, no monitoring records, warnings ignored - are exactly what the baseline controls address.
