If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

Water passing into the bowl can be easy to miss when the toilet still flushes normally. The fault may be inside the cistern rather than in the visible handle. Repairing the cause is more useful than reducing use alone.

Before arranging the visit

Listen for repeated filling and note whether water continues after the cistern should have settled.

Choosing the appropriate plumbing visit

We check the visible fault, isolation, pipe condition and access before agreeing the repair scope. Our water efficiency & treatment page explains the related work and how an assessment is arranged.

Where the findings point to water-saving tap installation, read the water-saving tap installation service details before discussing the repair scope. The actual fitting and access determine the work needed.

Information worth keeping

Record when the issue occurs, the affected room and any previous repair. For a property in our home area, plumbing in West Bridgford explains the local enquiry route; check the coverage directory for another postcode.
