Storage decides how the work is done
A cleaner with a lockable store on site can keep a scrubber, a vacuum, a mop system and consumable stock where they are needed. A cleaner without one carries everything in and out each visit, which limits what equipment can realistically be used and adds time at both ends of the attendance. On a large site that difference is substantial and it shows up in either the price or the result.
State what is available: a room, a cage, a cupboard, or nothing. State whether it is secure, whether it has a floor waste and a tap, and how far it is from the areas being serviced. A store at the wrong end of a large building is only marginally better than none. Where no store exists, say so plainly so bidders price a mobile method rather than assuming otherwise.
