Hughes;
Take a look at Leicester Race Course (N51 35.5 W001 05.44) I was in there one evening a few years ago when the Feds arrived and took a Gazelle, a 206 and 4 Robbie 44 owners/pilots to bits for landing in a congested area without permission.
I was in one of two AOC twins in there with all the correct permissions and was amazed that three of the pilots had CPL's and no idea of the requirements, the Feds spent a LOT of time with those guys, especially as the 206 was on a public transport flight.
