UK flood risk check by postcode
Free instant flood-risk band for any UK property, sourced direct from the Environment Agency. Premium upgrade adds surface water risk, groundwater risk, and 2050 climate-projected flood risk under UKCP18 scenarios.
Why flood risk matters before you offer
UK home insurance premiums for properties in flood zones are routinely 2-5x higher than equivalent dry properties. Some lenders also require a Flood Risk Survey before approving a mortgage. Discovering this AFTER you've made an offer can knock 5-15% off the price you're willing to pay — or kill the purchase entirely. Find it now.
