How to avoid a boundary mistake

Use Welsh Water’s property-level checker. County and community boundaries are too broad for a definite answer, especially near the edge of the affected supply area.

1. Confirm Dŵr Cymru Welsh Water supplies the drinking water.
2. Use the supplier’s postcode checker for the address.
3. Read the current restriction and exception details.
