Thanks all -appreciate people taking the time to respond.
Herts proved to be v helpful and good value, so good tip from richlan.
Regarding my previous cover (Autonet), their beef wasn’t to do with Brexit/green cards etc... they appear to have changed their policy on partial conversions so in reviewing my details flagged up that they wouldn’t cover me going forward. It does beg the question: if I hadn’t called up to check my Post-Brexit cover, then when would I have found this out? When I came to make a claim that they wouldn’t honour?! I also feel a little vexed that I’ve been paying a premium for some unknown amount of time for ‘insurance’ that was likely worthless!
Still, all sorted now!
