Water and flooding
- Shut the water off — main stopcock, or the valve at your tank. If you cannot find it, close the isolating valve nearest the leak
- If water is anywhere near electrics, cut power to that circuit at the distribution board. If the board itself is wet, or water is coming through a light fitting, do not touch it
- Open taps below the leak to drain the pipework
- Move furniture, rugs and electronics clear
- Photograph everything before you clear up, for insurance
