Quite honestly, I don’t think any insurance company would accept me due to a raft of unconnected medical problems. I have probably cost the NHS over £1 million over the years, and I have problems that will never be cured, only managed.
The only way I could afford the premium I would be charged, is if they gave a substantial dispensation for Armed Forces Veterans.
Which is when the Gov would step in and support, plus If we went down that route I’m pretty certain there would be an ex forces insurance scheme by most insurance companies, potentially part funded by Government.
