Why the map isn’t enough

Environment Agency flood zones are drawn at catchment scale and ignore surface water, defences and property-level ground levels. The risk at a specific Gloucester address can be very different from the zone shown for its street.

Frequently asked questions

Is Gloucester at risk of flooding?

Parts of Gloucester are. The dominant risk is rivers & sea (fluvial), driven by the Severn. In 2007 the nearby Mythe water treatment works flooded, leaving around 350,000 people without mains water for days. Risk is highly local, though — two homes on the same street can sit in completely different flood zones, so a town-level answer is only a starting point.

How do I check the flood risk for a specific Gloucester address?

The free GOV.UK flood map gives you the broad zone for a postcode. For a property you are actually considering, our £20 screening report pulls every open flood source — rivers & sea, surface water, reservoirs, groundwater and historic flooding — for the exact outline of that home, plus ground conditions, designations and more, in a single plain-English PDF.

Does flood risk affect house prices and insurance in Gloucester?

It can. Homes with a known flood history or a high modelled risk can be harder to insure at standard premiums (though Flood Re helps many residential policies), and that can feed through to value and saleability. Checking before you offer means no surprises after you have committed to searches and legal fees.
