Just so it’s documented it may be worth establishing the general cleaning tasks that need to be carried out. Bin wise we can save money on not recycling - yes I know it’s not the best solution but and extra £30 per bin per empty is money saved. Toilet roll wise we can again save money by making some cubicles “out of order” and I would suggest finding out how much gets changed when the cleaner does it. - Also cleaning supplies what do we need?
Also where do the council plan on keeping the bins? The cupboard will require them dragging them through the space, which we will then become responsible for cleaning. What if it’s raining when the bins are brought in.
