There is a legal way round this:
A supplier here in Bedford will make your plates up and will, to ensure they are legal, have their name and post-code added at the correct size. The catch, or loophole, is that these details are added in such a similar colour to the rest of the number plate you need to be within 2 feet and looking carefully to see them.
I can send you their details if you like or, if you wanted me to, I could have these made up for you and sent to you in the post fairly easily.
I have this on mine: It looks like the writing is there, but it says something other than it should
. As it appears to be making every effort to be as legal, and EU legal at that, I have never had any problems and have friends who are policemen who say that someone would have to be being incredibly anal to bother.

It might be "legal" to have them MADE like that .. but it illegal to use them on the public highway. These are "show" plates only ...
Unlike the VRN, there is no legal stipulation on what colour the writing has to be or how visible it is for the manufacturers name and postcode, only that it must not exceed a certain size.
EDIT: I have just confirmed this. It is not a stipulation as to what colour or font the plate makers logo needs to be.
Therefore plates made like this are legitimately and securely sold for "Road use" and
ARE NOT illegal.
Borders are legal too.
As my plates were made and fitted when the car was 1st registered in June 201 which is before the cut off date of 01/09/2001 then my plates are legal too.

I may be wrong (it wouldn't be the 1st time), so if you can show me the part of any BS (
British
Standard and not the other BS) that states anything to stipulate the font or colour of this manufacturers logo please and I will happily go back to the person who makes these plates as road legal and correct them.
