If it's the same ones, Wicked are based in St Albans. In my experience, lovely people and very helpful, even though I've not had cause to work with them recently.
It's a good time for BBC Local's @ the moment lots of diverse sung imaging emerging for stations, great sound for leicester. BBC Essex's new stuff from S2Blue went live on their birthday 5th November, so far from what I've heard not bad either.
