Our local council says not to put them out before 7pm but a lot of people here put them out much earlier. They remain on their properties so it's not an issue I don't think. Is there a cut off point where it becomes inconsiderate to wheel the clattering things from the back or side of your house to the front? We have 4 bins although it's rare for all 4 to go out at once. It's usually two. They make a lot of noise with their squeaking wheels, rattling lids and general clonking. Some people put them out anytime up until midnight, others at 6am on the morning of collection. What cut off would be reasonable in your neighbourhood or street?
