Take practical actions to prepare

There are a number of steps you can take to help prepare your property for flooding. These will help to save you time and money during a flood and can also help to reduce the impact of a flood on your

Step one 

Create a personal flood plan containing important information you would need to know during a flood such as insurance policy numbers, locations of gas, electricity and water mains and contact details for people you may need to get in touch with in an emergency.

Once completed, you should keep your flood plan somewhere safe and easy to reach in a waterproof folder. 

Step two

Prepare a flood kit of essential items that you would need during a flood, or in case of evacuation.

Your flood kit should include items such as copies of insurance documents, a wind up torch and radio, warm waterproof clothing and medication. Keep your flood kit somewhere easily accessible in case of flooding or evacuation.

Step three

Survey your home to identify the ways in which floodwater may enter the property and consider ways to prevent this occurring during a flood.

For example, consider keeping sandbags and plastic sheets to hand to put in front of the entrances to your property. You could also consider purchasing flood boards as another method of prevention.

  • Move valuables, photographs and sentimental items upstairs
  • Move rugs and lightweight items of furniture upstairs
  • Throw curtains over the rail out of reach of flood water

  • Clean and disinfect your property using ordinary household products
  • Use a normal garden hose to wash down surfaces
  • If you are drying your property naturally, keep windows and doors open as much as possible
  • If using dehumidifiers close all windows and doors

  • Contact your buildings and contents insurance companies as soon as possible and find out how long it will take for them to see you
  • Check whether they have a company that will clean your house or whether you will have to do this yourself
  • Check with them before throwing any damaged items away
