Flood defences in Bristol

Bristol's tidal defences protect much of the harbourside but surface water flooding remains a risk across many areas.

Understanding flood zones

• Zone 1 — Low risk: Less than 0.1% annual probability of flooding. Most properties fall here
• Zone 2 — Medium risk: 0.1% to 1% annual probability. Extra checks recommended before buying
• Zone 3 — High risk: Greater than 1% annual probability. Mortgage and insurance can be affected

Always check both river/coastal flood risk AND surface water flood risk for the most complete picture.
