Datchet has flooded for as long as records exist: village documents note 'great floods' in 1774, 1809, 1822, 1852, 1894 and 1947, long before the events in living memory. In February 2014 the Thames burst its banks and flooded properties across Slough Road, Eton Road, Horton Road, Southlea Road and Datchet Common — the same streets named in the Environment Agency's 'River Thames at Datchet' flood warning area — and closed the railway line linking Windsor with Staines for more than a week. In 2020 the section of the River Thames Scheme that would have protected Datchet and Wraysbury was removed after the Royal Borough of Windsor and Maidenhead judged its funding contribution unaffordable. Datchet, Horton, Wraysbury and Old Windsor were inundated again during Storm Henk in January 2024.

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 — Royal Borough of Windsor and Maidenhead 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 Datchet, 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.
