For some events, I know planning permission is required by local councils.

Oh yes the old purple plan !!!.regardless if you have CAA permission it dont mean you can go ahead and hold your little or large event as you may find all sorts of very official looking and some uniformed individuals knocking on your door asking why have you not consulted us ???.And then telling you all your planning is for nought as you aint doing it there and then or even at all.
