Recorded area
Where the restriction applies
Southern Water supply areas in Hampshire and on the Isle of Wight.
The current record covers Southern Water drinking-water customers in Hampshire and on the Isle of Wight. Southern Water also operates wastewater services elsewhere, which does not mean those properties receive their drinking water from the company.
Property check
How to avoid a boundary mistake
Use Southern Water’s property checker and confirm the drinking-water supplier shown on the bill. Do not extend the record to all of Hampshire solely from the county name.
- Confirm Southern Water is the drinking-water supplier.
- Use the supplier’s postcode checker for the property.
- Read the current restrictions and exceptions before acting.

What the source says
The supplier page showed the restriction as in force when reviewed. We have not imported an older notice date into the current record because the live source did not provide a reliable 2026 start time in the material captured for this snapshot.
