Um, I know from bringing a vehicle in from Jersey, which is part of UK, but not (It's complicated) but that had Jersey plates. I couldn't keep it in the country on those plates and had to register in UK as that's where I reside. There may also be insurance problems on a 'Forign' registered vehicle. You would need to display an English tax disc, or whatever system we are due to go over to later this year. And as for general standard of service. As you may have gathered if you've followed some threads DVLA/VOSA are a right bunch of ............... useless is the kindest description.
