Hi Ian
I had the same circumstances with LV.
Been a loyal(?) customer for over 40 years with no claims whatsoever and out of the blue comes an email saying they are declining renewal on my CT F Sport.
When I called to question the decision, I was told the reasons were high repair costs and theft. My car is 11 years old and garaged, so I think the risks are pretty low as I live on a farm in Sussex.
I was also told by the LV rep on the phone that they are also refusing to insure some types of Honda Jazz .............!!!!!!!
Also have an NX F Sport which LV are happy to continue insuring, but again, when I approached them for a quote to change my CT insurance to a 2 year old RX 450H they also declined.
Finally got my CT insured through AXA at a cost similar to last year.
Regards
Ray
