You have to notify the insurance company, usually pay an Admin fee.If you insure a car on a private plate but then put it back on it’s original plate (via DVLA) is the insurance void or is does it not matter in the short term given it has the same VIN and all other identification?
It’s dead simple if you follow the normal procedures and all done online in moments.What a palava, and a good reason to never have a personalised plate. You need to call your insurer, only they can answer this.
