Flooding health advice

Public Health England provides important information about risks to health caused by flooding

You're advised to take the following simple hygiene precautions when dealing with areas affected by flood water:

  1. Use rubber gloves and avoid contact with skin
  2. Wash down contaminated surfaces with hot water and detergent
  3. Wipe surfaces with a bleach solution, dilute one part bleach with ten parts cold water.
  4. Wash hands before eating and after contact with floodwater.
  5. If you are unwell seek advice from your GP in the usual way.
  6. Allow any pools of water to dry out.  Once areas have dried, and have been cleaned and disinfected, they are safe to use.
  7. If taps become contaminated, they should be cleaned and disinfected with diluted bleach solution, one part bleach with ten parts cold water, then left.  Run tap briefly to flush through water before using.

Get advice from the Environment Agency on what to do during a flood and read Public Health England's advice about health and flooding (PDF 5.3MB).

Protecting your property


You should make your own arrangements to protect your property from flooding. We will only look at requests for sandbags when people's homes are in imminent danger of flooding. 

If you are unable to get sandbags, you can use plastic bags or pillow cases filled with soil or sand instead. View the Environment Agency's leaflet on using sandbags for further information.

Sandbags are mostly used to hold back water from rivers that have burst their banks and occasionally for coastal defence.They aren't as useful for heavy rainfall and surface water flooding as they can stop water draining away if not put in the right place.

Preparing for flooding

The Environment Agency website provides useful information on how to:

The National Flood Forum website provides useful information and advice on flood resilience and resistance measures.

The Association of British Insurers has a guide to resistant and resilient repair after a flood (PDF 55KB).

Insuring your property

You should talk to your insurance company about their polices.

The National Flood Forum has advice for residents and businesses having difficulties getting insurance in flood risk areas. Defra has also produced guidance on getting flood insurance in high-risk areas.
