Make the observation useful
Compare actual readings, billing periods and changes in water use. A higher charge alone does not establish an underground leak.
A focused starting point
Mains water leak detection explains how a relevant investigation could proceed. The actual method depends on the system and findings.
What to put in your enquiry
- Where the sign appears and when it began
- The pattern around water use, heating or weather
- Earlier inspections, repairs or changes
- Your full postcode and access arrangements
If water is actively escaping
For immediate danger, keep away from unsafe areas and use the appropriate emergency or urgent assistance service. Website enquiries do not dispatch emergency help or guarantee an attendance time.
