Step by step
Protect people first
Keep children and pets away. If water is near sockets, appliances or the consumer unit, do not touch wet electrical equipment. Turn off power only if you can reach the switch without entering water.
Stop the source
Close the appliance valve if the leak is local. Otherwise close the internal stop tap, usually under the kitchen sink or near where the main pipe enters the property. Do not force a seized valve.
Limit the spread
Use containers and towels, move valuables, and open a safe drainage route only if this will not cause more damage. Never pierce a bulging ceiling.
Record and report
Photograph the source and affected rooms, note the time, and contact the landlord, plumber or insurer as appropriate. In a rented home, report it in writing as well as by phone.
Ready-to-use checklist
- Location of the stop tap known
- Water source isolated or professional help called
- Electricity risk checked without entering water
- Photos and times recorded
- Neighbour below warned if relevant
Common problems
The stop tap will not move
Do not use excessive force. Call an emergency plumber or your water supplier for advice on the external stop valve.
Water is coming through a ceiling
Keep out of the room, isolate electricity only from a dry safe position, and call for urgent professional help.
