01 / SURVEILLANCE

Legionnaires' disease in the North East England

The most recent regional figure UKHSA states explicitly: 17 confirmed cases of legionellosis in the North East England in 2023, a rate of 0.6 per 100,000 residents.

Whatever the regional count, the duties do not change: a non-domestic water system in the North East England still needs a risk assessment, a written scheme of control, and the records to show the scheme is being followed. Source: UKHSA national surveillance (Open Government Licence).

03 / WATER HARDNESS

Water hardness in the North East England towns

3 of 16 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.

04 / COUNCIL DUTIES

What councils in the North East England ask of landlords
