Guildford town centre sits at a natural narrowing of the River Wey and has seen notable floods in 1968, 2000 and the winter of 2013–14, and the Environment Agency is progressing a flood alleviation scheme for the town. Elsewhere in the borough, the Tillingbourne and, around Ash, the River Blackwater are the main watercourses associated with flood risk.
Flood risk varies street by street, so check your exact address on the Environment Agency's free tool — it covers rivers, sea, surface water and groundwater, and takes a minute.

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 Wey 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 — Guildford Borough 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 Guildford, 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.
