When I got my TS10 the copper told me that I didn't need to notify my insurance company till renewal. I double checked this with him and asked if this wasn't insurance company specific and he told me again, no you don't need to notify them until renewal.
Just done a quick compararison from a site, declaring my points, and trying the option that I have had my insurance cancelled.
My quotes have gone from £450 (what it used to be) to just shy of £1k
That will be the CU80 code
I've read a fair few times they are now taking this code very seriously and some insurers are refusing to provide cover at all if you have one on your license, much like lots of insurers refuse to cover anybody who has had a driving ban and any more than 3 points at once.
