Bloody hell, isn't there some law about how much noise can be made in a residential area before 9am?

Obviously not.

Next door neighbour (of the noise/fence saga fame) is having something done in the "garden" requiring excessive banging and chiselling at 8.30am.

In my mind it plays out like this;

I'll get those bastard night-owls next door... [reaches for phone, dials building company] "...great. How early can you come and make a shitload of noise in fifteen minute intervals?" [ends call, rubs hands together with glee]. She's still on holiday too, even better [evil cackle].
