- Full property address, so we can review the location and property-specific evidence.

- Known flood history, sales particulars or plans, if available.
- Any lender, valuer or insurer question, so the scope addresses the stated concern.
What a map or conveyancing search can and cannot tell you
You can check the long-term flood risk for an area as an initial screen. The Environment Agency Flood Map for Planning and RIDA’s Flood Map for Planning resource concern planning flood zones. Maps and searches provide useful evidence, but may not explain how several flood sources, local features or data limitations relate to the house you are considering.
House Purchase Flood Risk Assessment FAQs
Is a conveyancing flood search enough when buying a house?
A search is a useful screen. A property-specific assessment may be appropriate if it flags risk, evidence conflicts or a professional adviser asks for technical interpretation.
What information do you need to assess a property before purchase?
Send the address, purchase deadline, available searches, known flood history and any question raised by your solicitor, lender, valuer or insurer.
What will a house-purchase flood risk report cover?
The report reviews relevant available flood sources, mapped exposure, flood history, local context, defences and residual risk. It records evidence gaps and recommended next steps.
How are the fee and programme confirmed, and what if further assessment is needed?
