Your local council HAS to follow up every complaint even if its bogus. Enforcing it is another thing. The watershed where i am is @ 10pm, but im in a private house so i dont know if there are different rules if your are renting or in council owned.
To enforce a noise pollution order (to get you into court) they have to prove you are above a certain dB level and that the noise is persistent.
If had the local council round because of an asshole alcoholic neighbour complaining about my dog keeping him awake at 3pm. The enforcement officer came round and my dog sat looking at him for 15 mins not a peep, meanwhile asshole neighbours dog and 4 other dogs in adjoining gardens were going ballistic. I had to bring him into the kitchen to hear what he was saying :lol:
If your doing a bit of hammering or grinding @ 7pm they wont be able to do anything to you. But you must show you are co-operating with council officials if they visit etc.
. If you show your neighbour out to be out of order they will soon leave you alone.
