I haven't looked into insurance yet but 'our' street and Chris's have never actually flooded despite being the closest two to the waterworks/marshes
It's worth having a check (I'm surprised your solicitor hasn't told you to). To an extent the insurers will be working off the same reports that suggest it's at risk of flooding so a quick 10 minutes to confirm that it won't be an outrageous cost is sensible.
We told the solicitor we knew about the flood risk and were going to buy it anyway which might be why she hasn't. Anyway, I will check this lunchtime. Chris seems to be OK so I think we will be too.
My place is marked as high risk of surface flooding and that didn't seem to impact on the insurance materially but my brother tried to buy a place that was uninsurable due to flooding so always worth a check.
