01 / SURVEILLANCE

Legionnaires' disease in the East of England

UKHSA does not state a confirmed case count for the East of England in the surveillance text. Full region-by-region counts for every English region are not published; the figures that are published are on the national Index. Surveillance counts only laboratory-confirmed, reported cases, so any published figure is a floor, not the true total.

02 / ENFORCEMENT

Prosecutions tracked in the East of England

The tracker holds 4 legionella prosecutions from the East of England, totalling £3.43m in fines (2013–2018).

Bupa Care Homes (BNH) Limited Death/outbreak
An 86-year-old resident died of Legionnaires' disease at a Brentwood care home in 2015, months after refurbishment. The company failed to flush and disinfect the system, the manager lacked training, warnings were ignored and records were falsified. Fined £3m, reduced to £1.5m by the Court of Appeal. Source
2018 Care home £1.5m HSE
Tendring District Council
A member of the public contracted Legionnaires' disease from the water system at the council-run Walton-on-the-Naze leisure centre. HSE found inadequate risk assessments, insufficient staff training and a lack of monitoring across several council leisure sites. Fined £27,000 plus £7,197 costs and a £170 victim surcharge at Colchester Magistrates' Court in December 2018. Source
2018 Local authority leisure £27k HSE
G4S Cash Solutions (UK) Limited
Environmental health officers inspecting a Harlow cash depot found erratic monitoring, untrained staff and no adequate water-system risk assessment. Legionella was not confirmed on site but workers were exposed to risk. One of the largest legionella fines, brought by a local authority. Source
2016 Security £1.8m Harlow Council
Basildon and Thurrock University Hospitals NHS Foundation Trust Death/outbreak
A chronic legionella outbreak in the hospital water system in 2006 to 2007 infected seven patients; two died (James Compton, 74, and Raymond Cackett, 54). Shower heads, hoses and thermostatic controls were not maintained. The Trust admitted breaching HSWA s3(1) and was fined £100,000 for the legionella offence plus about £162,000 costs at Chelmsford Crown Court in September 2013. A larger reported total from the same hearing reflected a separate, unrelated incident. Source

03 / WATER HARDNESS

Water hardness in the East of England towns

15 of 26 towns here carry a reported hardness figure; the rest show a band inferred from the water company's own statement, or an honest gap. Every row names its source and confidence. Scale risk uses the DWI/WHO anchor: scaling begins around 200 mg/l CaCO₃.
