EN Department Official Travels Office

Opening hours

The office is open during working hours from Monday to Friday.

Preparing your Trip

A new Travel document (TRVL) is available on the EDH desktop. This single document replaces both the duty travel request (TREQ) and the Travel claim (TCLM). Please submit your travel document (TRVL) 14 days prior to departure, at the latest 48 hours before travel and collected by EN Department Official Travels. 

A duly approved travel document - prior to departure -  is mandatory to obtain the reimbursement of travel expenses.

As with any change, a transition period will be necessary. Please do not hesitate to contact, for assistance.
