What this means for buyers and insurance

Flood zones are mapped at street level — an outcode is too coarse to decide on a single property. A home a few metres from a Zone 3 boundary can be Zone 1, and vice versa. Treat this page as the area context, then check the exact address.

Ask the lender which searches are needed and obtain an insurance quote for the exact property. Flood Re provides reinsurance for eligible risks; the insurer sets the customer's premium, excess and terms. Ask the seller about previous flooding and have your conveyancer follow up the answers and supporting documents. How Flood Re works.

Frequently asked questions

Is IG1 in a flood zone?

What do the flood zones mean for buying a house?

Flood Zone 1 is low risk (below a 1-in-1,000 annual chance of river flooding). Zone 2 is medium (1-in-100 to 1-in-1,000). Zone 3 is high (1-in-100 or greater from rivers, or 1-in-200 from the sea). A home in Zone 2 or 3 can be harder to insure and mortgage, and you should ask the seller about flood history on the TA6 Property Information Form.

Does a flood zone affect insurance and mortgages?

A planning zone does not determine the premium, lender decision or Flood Re eligibility. Flood Re is a reinsurance scheme; insurers set the customer's prices and terms. Ask the lender and obtain a quote for the exact property, checking any scheme eligibility with the insurer.

How do I check flood risk for a specific IG1 address?

Start with the Environment Agency long-term flood service and Flood Map for Planning, and ask separately about previous flooding and insurance terms. Our free tool explains postcode screening; Complete (£24.99) brings available records into a human-checked report with source and location limits. It cannot establish this building's full flood history or insurance terms.
