ooo yeah, car insurance. One of the Top Five most difficult, confusing, time-consuming and expensive parts of moving to the UK (and there's no shortage of those). Without any no-claims bonus, you apparently pay 5 times more. If you don't have a full UK licence (I had a NZ licence which is just a straight 'swap' with a UK licence), then many insurers won't even cover you.
This is before you get into any of the other, more usual, car insurance issues. They 'ignored' my claims about not having a full UK licence and my policy was for a UK licence. If I'd had a crash, I would have not been covered at all. It cost me lots just to cancel the contract.
I'm now with Aviva. It seems reasonable - but after spending many many hours on this, and finding insurer after insurer who wouldn't even take me on - I just wanted whatever I could get. I pay about 8-900 pounds a year,
