Actions to take before flooding
Sign-up for updates: You can register a phone number and email address with Floodline Warnings Direct or call 0845 988 1188 for up-to-date alerts.
Store electrical items and valuables upstairs: Unplug electrical items and store them on high shelves or upstairs. Similarly, irreplaceable valuables should be kept upstairs, or at another location.
Protect important papers: Documents such as passports, driving licences and insurance policies should be kept in watertight containers. Give copies to friends and family for safekeeping.
Keep useful phone numbers to hand: Make a note of numbers you may need if flooding strikes. This includes your insurer’s emergency helpline and local council numbers.
Prepare an emergency kit: Bundle together in a waterproof container a torch, candles, batteries, radio, a fully-charged mobile phone, waterproof clothing, blankets and a first-aid kit.
Sort out your buildings and content insurance: Check your buildings and contents policies are up to date, and that you have the paperwork to hand.
