Thames Water restriction status

Thames Water’s legal notice applies across the company’s whole supply area from 00:01 BST on 23 July 2026.

ScopeWhole supply area

Recorded area

Where the restriction applies

The whole Thames Water supply area.

The notice follows the water supplied by Thames Water. It can therefore apply where another company sends the bill on Thames Water’s behalf. Conversely, Thames wastewater services alone do not establish that the drinking water comes from Thames.

Property check

How to avoid a boundary mistake

Confirm the drinking-water supplier and read the legal notice linked below. The checker’s boundary estimate is useful for finding a candidate company, but the bill and supplier notice are stronger evidence for a property.

  1. Confirm who supplies the property’s drinking water.
  2. Read Thames Water’s legal notice and exceptions.
  3. Recheck the notice if the planned use is unusual or essential.
