1. Shut off the water if it is safe
- Locate the nearest isolation valve or the property’s main stopcock.
- Turn it off only if you can reach it safely without entering flooded areas near electrical equipment.
- Open a cold tap briefly after isolation to relieve pressure if appropriate.
2. Watch for electrical risk
Water and electricity are a dangerous combination
If water is near sockets, appliances, light fittings or the distribution board, do not enter the wet area to switch anything off. Keep clear and arrange qualified help. For immediate danger, call 112 from a mobile.
3. Reduce damage without creating more risk
- Move small valuables away from water only if the route is safe.
- Use towels or containers for minor accessible leaks.
- Do not stand under water-damaged ceilings or climb into wet ceiling spaces.
- Take clear photos from a safe position for the service provider or insurer.
4. When a plumber is needed
A burst or failed pipe normally requires a plumber to identify the damaged section, repair it and check for secondary leaks. If water has affected ceilings, walls or electrical systems, additional assessment may be needed.
