Why the need to do this so early?

I imagine she is, and she will also be one of those people who "always" does [insert pointless task designed to irritate other people and make herself feel superior].

Just have a word with her, let her know it's waking you up

There's no way that she doesn't already know that she will be waking people up. Even the 'straightening up' that she also insists on doing sounds like it's calculated to make maximum noise for maximum disturbance.

I wonder if she's just one of these selfish people with a self-imposed very, very tiny world, who thinks it somehow makes her 'better' than everybody else, just because she arbitrarily gets up very early (and likely has an afternoon nap anyway), and wants everybody to know that. It's amazing how many of these people will choose random routines for themselves and then think that others should be expected to do the same, or otherwise be rightly criticised for their 'failure'.

Just have a word with her, let her know it's waking you up and ask if she would mind doing it at a more neighbour-friendly hour. If she's worried she might forget if she doesn't do it first thing, you could offer to take her bin out at the same time as you do yours.

Send me her bin, I’ll tip it over the bonnet of the annoying dickhead next door who likes to rev his fucking orange fucking sports car at 6 a-fucking-m

The evening before

It’s a few minutes of noise.

It's a few minutes of entirely unnecessary noise, made deliberately at a time when they know that most people will be trying to sleep.

If somebody has a small child who is woken an hour or two early by the noise of the bins on a weekend day, and then can't/won't go back to sleep, that will have a real negative impact on the parents' whole day - for absolutely no reason whatsoever.

Our two opposite neighbours both put their bins out at 10 am Sunday morning and our rubbish is not collected until Monday early afternoon. They put their bins in only area where visitors can park.

My first thought is that it could be a genuine health problem causing memory loss/anxiety and she’s trying to maintain independence/lower anxiety by putting them out in advance.

My second thought is maybe she feels safer putting them out when it’s light rather than last thing at night when she could be attacked in the dark.

YANBU.
We put ours out between 7-10pm on Sunday night. The sound of us doing this seems to summon my surrounding neighbours and within half an hour of ours going out all their bins are out too!

Glue her bins shut one night.

Our bins are collected at around 5.30/5.45am. So people put their bins out the night before. Recently this seems to be getting later and later - the last few weeks I have been woken at around 3.30 by noisy bins. Hardly seems worth trying to go back to sleep at that point.....
And then every other week our garden waste bins are collected the day after the ordinary bins, at the same time. So two days in a row of late putting out/early collection.

I put mine out the night before, otherwise I risk missing the collection. They seem to rock up whenever they feel like it. Which can be any time between about 5:30 and 9am.
If they've been and gone by the time I leave for work at about 7:30, I'll quickly bring them in again. Otherwise they'll continue to sit out until I get home at 5ish.

Maybe she is, but the choice is being woken early every Sunday morning by it and post on Mumsnet, or you can speak to her and ask her to stop. Some people need it explaining.

Garden bin Sunday afternoon/evening as they come early Monday morning. Other 2 Tuesday morning as we leave for work as they come in the afternoon

Evening before like everyone else, they collect at 7am

It’s a few minutes of noise.

If a few minutes of noise truly bothers you that much the only option is to live in isolation.

If it was excessive and going on for a long period of time, the complaint is valid. As it’s not, the complaint is just silly.

Its expected noise in a residential area, which is annoying. But you can predict it and ear plugs exist.

It might just be her routine and she doesn’t think, some people need it explaining to them.

She must be either very selfish or very dim, if so. What are the actual benefits to anybody in putting it out early on a Sunday morning instead of on Sunday evening or Monday morning?

With bin collections, the council dictate the routine for everybody - it isn't really an individual choice.

The council changed refuse collectors a few years ago to working every day, we were the unlucky ones that got a Sunday. I’m sure it was a cost saving exercise.

Ah, how annoying. I'd have thought they'd have to pay workers more to work on a Sunday, so it wouldn't save costs; but councils do have their own (often illogical) ways of doing things.

I'll bet, if you regularly made the same amount of noise early on a Sunday morning - using power tools or mowing the lawn - they would be after you for antisocial behaviour!

That was in reply to @FatherJackHackettsUnderpantsHamper

There aren’t really any streets in the whole council area that get too congested for the bin lorries as it’s a suburb of a big city and a lot of rural villages.

Have you spoke to her. It might just be her routine and she doesn’t think, some people need it explaining to them.

Our council say not to put them out till 5pm the night before. They start collecting at 5am though and I am fed up being woken at that time by the banging and dragging of bins!

Our bins get collected on a Sunday morning so get woken up early every Sunday.

Wow, that's unusual. Does the council have a particular reason for choosing Sundays? Is the road extremely busy in the week?

In our road everyone puts their bins out the day before. Usually the afternoon or evening before and never at a time when anyone could be asleep. They are collected from 7am on the day. I didn’t think they were allowed to collect the bins before 7am. The same as noisy building works. I just wish milkmen would come at reasonable times.
