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.

Watch for evidence that repeats

One damp mark does not always identify the source. Repeated meter movement when outlets are off, pressure loss, staining, peeling finishes, musty smells and warm or cold patches can justify further checks.

  • Photograph changes over time
  • Check the water meter only if safe and accessible
  • Do not open walls or floors without a reasoned plan

Limit damage without hiding evidence

Move possessions away, catch accessible drips and isolate the affected supply if it is safe. Avoid painting over marks before the moisture source has been investigated.

Choosing the appropriate plumbing visit

The aim is to narrow down the likely source before opening finishes or replacing parts. Our leak detection & repair page explains the related work and how an assessment is arranged.

Where the findings point to hidden water leak detection, read the hidden water leak detection service details before discussing the repair scope. The actual fitting and access determine the work needed.

Information worth keeping
