The call-out charge: what it covers
The call-out charge (also called the mobilisation charge or attendance fee) covers the operator's cost of responding to the booking: leaving the base, driving to the scene, and presenting at the vehicle. It is a fixed charge, not a per-mile charge. On the National Highways NRS tariff it is labelled 'Attendance' and the figure is published in the tariff schedule. On a private booking it is the base element of the band.
The call-out charge is payable even if the operator arrives and the fault is not what was described. If you booked a jump start and the fault turns out to be an alternator failure that requires a tow, the call-out for the jump start attempt is payable. The tow is then quoted as the revised job.
On the invoice: look for 'call-out', 'attendance', 'mobilisation', or 'response fee'. If you see two call-out charges on the same invoice for a single job, query it: one job = one call-out charge.
