I am getting married in the UK December 2019, but I currently reside in the United States. My venue is old and has a lot of irreplaceable items. The venue has requested I have a £5M liability insurance policy from a reputable source based in the UK. They said it's usually ~£50-80, so I don't mind. The problem is that I cannot find an insurance provider who will write a policy for someone who does not reside in the UK. Many websites flat out say it, and for those that don't, I've gotten 3 letters declining me for that reason.
This venue is my bride's dream. We cannot move this wedding anywhere else. I have requested help from the venue, but they said for liability reasons they cannot recommend a specific company.
