Around South east london, I think there's 1001 other things for the police to be dealing with, so no front plate seems to be OK, as the back one get's caught be the speed cameras - not my opinion, just seems to be the way.
It's unacceptable, but lots of decent looking cars don't benefit from a standard sized front plate - if I had such a problem, I'd bend it a little with a stick on one, or a small one rather than go without.
