Plan the appointment after the room scope is clear.
Give the Sutton postcode, selected rooms, bathroom numbers, levels and condition. Mention a date if needed and check availability. Ask how the proposed hours and team size relate to the work; unused rooms are not automatically identical workloads.
The team brings cleaning products and tools. Share allergies, prohibited products and material instructions before attendance. Make intended areas accessible as agreed, or describe clearing work you want considered. Privately arrange entry, alarms and locking up, including shared doors and relevant parking arrangements.
