Municipal Year Book has search facilities that let you look for municipal employees in England, Scotland, and Wales, by job function, council, or keyword.

So handy for finding out who's actually responsible for,maybe, planning, prior to cross checking against company records for directorships (say) if, for example, a suspicious deal has just gone through near where you live.

You could also cross check with council minutes, which are supposed to be publicly available.

Or you could just use it to find the name of the person in charge of the council tax department, or whatever.
