Lucy - Be careful on the mis spacing. These days they can not only pull you and issue a fine (upt to £1,000), but confiscate the plate without recompense. I would however expect the first time you'd get a 7 day warning to fix it.
OK - DVLA regs on smaller platesfor normal UK cars (not to be confused with non EU type approved smaller plates that have excemptions)

So long as there is 11mm at the top, bottom and side margins it's fully complaint (of course observing the correct spacing, font size, etc.) but we are only concerned in this tread about cut down plates.
