The night before is before 7AM

It does NOT say:

"No earlier than xxx time/day"

It's not reasonable to expect everyone to get up and put the bins out prior to 0700. That's why half the planet will put them out the night before, and the council be perfectly happy with this.

I have seen councils say no earlier than maybe the lunchtime prior, just to make sure they are not out for days before. Usually in places where pavements are really small.
