The conditions that make presentation workable
Three things determine whether a cleaner can present bins reliably. The path has to be safe, level enough and clear of vehicles. The bins have to be movable by one person, which rules out overfilled or very large units on some surfaces. And the collection timing has to align with the cleaning attendance, which is often the item nobody checks. A bin presented twelve hours early is a nuisance to the neighbours and a target for illegal dumping.
Where those conditions are not met, the honest answer is that presentation should be done by the site. That is not a failure of the cleaning arrangement; it is a recognition that a task requiring someone to be present at six in the morning does not fit a service attending at seven in the evening. Saying so during scoping avoids an arrangement that fails intermittently and blames the wrong party.
