Maps show hazard layers, not your basement
Surface water and coastal risk can differ street by street. Use official layers and consider how drainage behaves in extreme weather.
Insurability
If mainstream insurers are cautious, your costs may rise — factor that into affordability alongside council tax and heating.
Lenders
Some institutions apply heightened scrutiny in high flood-risk zones; your broker can confirm early.
