Why arrangements change when agents do
An incoming agent inherits contracts they did not negotiate and cannot easily assess. Replacing them with providers they know is simpler than evaluating what exists, and it is not necessarily improper. The difficulty is that a functioning arrangement can be replaced without anybody establishing whether it was working, and the building loses accumulated knowledge for no measurable gain and the new arrangement starts from nothing at a building nobody has learned.
The reverse also happens. A poor arrangement survives an agent change because nobody reviews it and the invoices keep being paid. Either way, the change of agent is a natural moment to look at the cleaning properly. What should not decide it is whichever option requires less work from the person newly responsible for the building and that is the outcome this whole exercise is meant to prevent.
