A couple of friends have used and recommended www.fancyplates.com so I decided to give them a try for myself. Although their website isn't that great they did deliver me the 3/4 plate I specified, the very next working day. I only ordered the front plate as I'm happy with my rear plate, but I would've liked to have been able to specify the blue GB euro bit, but I'm happy with to finally have a smaller front plate.
In probably the quickest mod I've done to the car, I used some 15kg Velcro to fit and voila - the front end looks like it's had a decent 'upgrade' - before and after pictures below.
