Define a standard before defining a frequency
A useful fleet enquiry starts with the result required for each aircraft. Specify the cabin areas to be included, the exterior cleaning priorities and any differences between aircraft types. One broad instruction can hide very different workloads across a mixed fleet.
Create a simple checklist for the agreed clean and identify the person who can review the result. This gives the operator and cleaning team a common reference when discussing included areas, exceptions and future visits.
Separate routine work from additional attention
Regular cabin presentation can be planned separately from more involved cleaning after spills, heavy use or a period of storage. The same applies to exterior work: a maintenance wash and a clean of a heavily marked aircraft should not be treated as interchangeable.
Describe unusual marks or extra requirements before the visit so they can be assessed and quoted. A repeat arrangement should leave a clear route for approving work that falls outside the normal work.
Build the schedule around each aircraft
Share typical availability, the relevant London airports or hangars and how changes are communicated. A proposed frequency is a starting point for discussion, not a guaranteed slot. Access, working conditions and individual aircraft movements still need to be confirmed.
For a multi-aircraft request, list each aircraft and its needs separately. Include the booking contact, who approves the work, who arranges access and who signs off the work. Avoid sharing passenger manifests or confidential flight information in the initial form.
