I came off Motability in 2019 after around 13 years. RSA sent separate emails for myself and my wife that were called “Proof of claims History” rather than No Claims Bonus.
It mentioned in each email ” not all insurance providers will accept this claims history letter” and suggested Autonet as an insurer who would accept it.
I did the usual comparison search and LV= offered the best deal. I contacted them and they said that they also accept RSA/Motability claims history as NCB.
Since that first year with LV= I have changed insurance companies and all has gone smoothly. I.e. nothing is mentioned about Motability.
It worked out very well as I’m rather certain that named drivers don’t usually earn NCB. Although I’m not sure where my wife would stand if we were ever to get a second vehicle as she has been a named driver on a regular policy for last few years.
