Hi saanen,
You will find that in a lot of conveyancing, clauses are set out regarding this issue. Quite often in freehold and leasehold property it will state that working from home is forbidden, and that the dwelling is for residential purposes only. Some clauses become almost 'obsolete' because it has been set out by the developer that say "no commercial vehicle is allowed in view of the estate", merely to stop any vehicles other than cars to line the street or driveways, because it might deter would-be purchasers from buying when the property is new.
Having said that, councils usually take a dim view on someone using their residential property for business practices (even legit ones lol), so a phone call to them would be advisable. The noise and safety factor would come into it also. You certainly have a valid case for complaining, either in the former para or the later.
Good luck !
