I recently left the scheme, so I totally get where your coming from, It’s hard to justify such high ap’s with nothing to show at the end, for me ther’e quite a few other reason as to why it’s just not as viable for us as it once was.
After checking comparison sites and a few other insurance companies, not on those sites. I then called a few up that didn’t list it as an option on there sites and they all accepted the rsa letter of claims history. Which you can only get once you hand the car back and leave the scheme.
When the policy came they said my nch had been verified, so no need to send them anything.
I did ask rsa before leaving the scheme, how much nch i had and they put me threw to another dept who told me.
As for getting Insurance, definitely shop around. There was some big differences between the amount of some for the same level of cover.
Also it did rise slightly from when i got the original quotes when looking to when i actaully needed to take it out on the day after picking up the new car, as dealer covered me for 24 hrs.
I went with the company we have our home insurance with as I got a discount for having that and it worked out a good deal.
Also it’s cheaper if you pay for the whole year and i actually got a better price over the phone than I did online. As the system was not seeing my private plate on their sites.
