Flood risk
You printed an England flood check for a house in Wales. Why is that the wrong map to wave at the surveyor?
Not the map for this house. An England flood check is the wrong document to wave at the surveyor for a house in Wales. The GOV.UK long-term flood check is for an area in England. A printout from that service, however official it looks, is not the flood mapping for a Welsh address. Handing it over asks the surveyor to comment on the wrong geography. The survey can still describe what it sees on the plot. It should not be asked to treat an England PDF as the flood information for Wales.
Last reviewed 24 October 2026. Written for buyers in England and Wales unless this answer says otherwise. No named surveyor has signed this page. It is general guidance, not a report on your house, and not legal advice.
What is the fuller explanation?
The mistake is easy because the page looks like a national answer and the house is still in Britain. The service you printed is defined for England. A Welsh house is outside that check. Waving the PDF does not become correct because the postcode was typed carefully, or because the colours look decisive. If the address is in Wales, this is the wrong map. Say that plainly, and do not staple it to the survey as if it were the property's flood record.
Ask the surveyor to keep site comments separate from that printout. They can describe ground levels, a stream, a low door, or stains they actually saw. They cannot validate an England flood check as information about a Welsh house. Your solicitor can ask which flood information is proper for the address. Until you have the right map, do not negotiate, insure, or reassure yourself from the England PDF. The survey is not there to launder the wrong document.
What should you ask your surveyor?
- Will you set aside an England flood printout if the house is in Wales?
- What on the plot can you describe without using that PDF?
- Which low points did you see that a map, right or wrong, would not photograph?
What are the typical next steps?
- Do not give the surveyor an England flood check for a Welsh house.
- Keep the survey's site notes separate from that printout.
- Obtain flood information that actually covers the Welsh address.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the England page still shows the postcode, can you use it?
No. The long-term flood check you printed is for areas in England. It is the wrong map for a house in Wales.
Does the survey become a flood map if you attach the PDF?
No. The survey describes the visit. Attaching the wrong map does not make that map right, and it does not turn the PDF into Welsh flood information.
