There are 3 levels of flood warnings:
If you leave your home during a flood you’ll need to turn off your mains water, gas and electricity if it’s safe to do so. You should find out in advance how to do this.
The location of water stopcocks, gas shut-off valves and electrical master switches varies between properties. The gas shut-off valve is usually beside the meter. The mains electricity cut-off is usually a big red switch on your fuse box. If you can’t find your water stopcock, ask someone with practical experience or a plumber to help you.
Make sure you have insurance to protect your home or business. If you have buildings and contents insurance, check if flood damage is included.
If you rent your home, it’s your responsibility to protect your belongings.
