I found the process very simple - organising the new plates online saved a trip out to a supplier. I ordered 2 sets of plates and they were well packaged and fitted easily through the letter box. The email confirmations I received were prompt - and indeed my new plates arrived safely within a couple of days. Obviously you need to scan and email your ownership documents, and measure your car/existing plates before you start, and feel confident about changing over the plates yourself (but, frankly, this is just a matter of a couple of self-tapping screws and some double-sided stickers). I thought the Demon Plates website was very honestly written, and the service pretty faultless.
