UK national events run to UK rules and these allow the bigger restrictors that WRC cars have, so there's nothing to stop you from putting the bigger restrictor on a Rally2 or R5 car. When R5 cars were first introduced nobody in the UK ran them as old WRC cars were cheaper and quicker. Those who wanted to run the newer R5 cars, when they became available second hand, needed to fit the bigger restrictors to be competitive. If you were to restrict entries on UK events to cars complying with their FIA homologation you'd decimate the entries because very few cars in the UK run to their homologated specification.
