DEBA UK Ltd A risk-assessment contractor (not the care-home operator) carried out inadequate legionella risk assessments in 2007 that wrongly rated two Craegmoor Healthcare nursing homes in Wales as low risk, where controls were in fact inadequate. No outbreak or death resulted. Pleaded guilty to three charges under HSWA s3(1) and was fined £24,000 plus £17,276 costs at Abertillery Magistrates' Court in August 2009. Notable as a prosecution of the assessor rather than the duty-holder. Source

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.
