Tonbridge sits on the River Medway and flooded badly in September 1968, when a wall of water swept into the High Street and Cannon Street bridge collapsed. That event led to the Leigh Flood Storage Area, built upstream and completed in 1981, which held the town largely dry during the October 2000 floods that overwhelmed much of the surrounding Medway valley. In the winter 2013/14 storms the storage area protected 938 Tonbridge homes, but the event exceeded its design capacity and more than 900 homes and businesses flooded across Tonbridge, Maidstone, Yalding and East Peckham. A £36m expansion of the Leigh scheme, with new embankments at Hildenborough, has been under construction since spring 2023 and is due to be fully operational by autumn 2026, reducing flood risk to over 1,800 homes and 575 non-residential properties.

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 Medway 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 — Kent 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 Tonbridge, 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.
