My house is shown as high risk from surface water flooding and low risk from the rivers and sea on here https://check-long-term-flood-risk.service.gov.uk/risk but realistically no houses in the area have ever come near flooding and I suspect the insurance reflects that.
I know of someone in York on the other hand with a house by the river that was pretty much uninsurable due to the actual regular flooding.
As others have said, try a few insurance companies to start and see what they say. Also, if you can, knock on a few people's doors nearby and say that you're thinking of buying and wondering if they have ever had a problem with flooding.
It depends how at risk it is.
