When does it become more cost effective to use a hire car instead of grey fleet?
This will depend on the deal your organisation has in place for vehicle hire and typical patterns of usage in terms of vehicle size, length of hire and delivery and collection. Analysis in a number of public sector organisations has indicated that the typical point at which it becomes more cost effective for an employee to do a one-day journey in a hire car rather than the grey fleet is somewhere between 75 and 120 miles for an Astra-sized vehicle with delivery and collection.
