The outgoings statement is a cleaning document
Most tenants read the outgoings statement as a list of charges and stop there. Read as a description of services, it tells you what the building undertakes to do: cleaning of common areas, external window cleaning on a cycle, waste removal, pest control, and often amenity servicing where washrooms sit outside the demise. Each of those is a line you do not need in your own scope.
The figures also indicate the level of service. A building recovering substantial cleaning costs is generally providing a substantial service in the common areas, and your tenancy scope can be written on the assumption that the lobby, lifts and corridors are handled well. Where the recovery is minimal, expect to compensate for that at your own entrance and reception. Comparing the recovery against what you observe in the common areas is a useful sanity check on both.
