Water company register
Restriction status by drinking-water supplier
Nine supplier records were checked 23 September 2026. Company pages explain the recorded scope, the date and where a property-level check is still needed.
Why company pages?
Supply boundaries do not follow place names neatly
A county, town or postcode district can contain more than one drinking-water supplier. We publish pages only where there is a current company source. We do not generate thin pages for every location.
