What to do when water is leaking at home

Act only where it is safe. These first steps can help limit damage while you arrange appropriate plumbing help. They do not identify the cause or replace an inspection.

1. Identify what is happening

Check where water is visible, which fitting was last used and whether the flow is continuing. Do not remove panels or disturb damaged finishes just to find the source. Water can travel away from the point where a leak starts.

2. Isolate the water if it is safe

WaterSafe and Thames Water advise using the internal stop tap or stop valve to turn off the incoming supply. It is often under the kitchen sink or near where the supply enters the property. Turn it slowly and do not force a seized valve. Shared supplies and external valves need extra care.

3. Limit further damage

Use a container or towels where this can be done safely and move belongings away from the affected area. Avoid mixing drain chemicals or attempting work on damaged, corroded or inaccessible pipework.

4. Send useful details

Include the postcode, room, affected fitting, when the problem began and whether the water can be isolated. Photos of the complete fitting, visible connection and surrounding access can help. Do not send keys, access codes or private documents.

5. Arrange the right next step

For an active leak, call to check whether Fixright can attend. Scope, coverage and timing are confirmed directly. If the leak appears to be on the outside supply pipe, contact the local water supplier because responsibility may differ.
