Chertsey has two distinct flood sources: the Thames, which spills out across Chertsey Meads, and the Chertsey Bourne, a smaller tributary running through the town. The 1947 flood remains the historic benchmark for the Thames here. In February 2014 the river burst its banks again — across Surrey around 1,000 homes were flooded and about 600 properties evacuated, with 368 homes flooded in Runnymede borough alone. During Storm Henk in January 2024 the Bourne overflowed, homes on Eastworth Road flooded and properties in the town were evacuated.

A flood warning usually gives you hours, not minutes. Use them in this order:
- 1Check the warning level. A Flood Alert means be aware; a Flood Warning means act now; a Severe Flood Warning means danger to life. Follow EA updates for the River Thames warning area.
- 2Move what matters. Take valuables, documents, medicines and irreplaceables upstairs or to high shelves. Move cars to higher ground early — flooded roads close fast.
- 3Deploy your kit. Sandbags or barriers at doors and airbricks if you have them — Surrey County Council publishes its sandbag policy on its flooding page.
- 4Prepare to switch off. Know where your electricity, gas and water shut-offs are, and switch off if water is about to enter — never touch electrics standing in water.
- 5Grab bag by the door. If you may need to leave: medicines, documents, chargers, warm clothes. Follow evacuation instructions from the emergency services, not social media.
Prepare your household
The same short list serves every emergency: water, food that needs no cooking, a torch, a charged power bank, and — if you're in a flood-risk street — a plan for moving valuables up and kit for keeping water out.
Flood insurance, and Flood Re
If your home is in a higher-risk part of Chertsey, check your buildings and contents policies actually cover flooding, and at what excess. Homes that struggle to get affordable cover may be helped by Flood Re — the government-backed scheme that lets insurers pass on the flood part of eligible home policies, which typically makes cover cheaper and easier to find. Your insurer applies it automatically; if you've been quoted badly, ask specifically about Flood Re-backed policies.
After any flood, photograph everything before cleaning up, and contact your insurer before disposing of damaged items.
