For your peace of mind, Jafvans maintain a 24 hours emergency telephone service. Number is given on Rental Agreements. This breakdown is exclusive to the UK and the insured drivers only. Please note that we have to pay all call out charges – if the breakdown service is called out for an unacceptable reason or a driver error, then the hirer will be charged the full service cost. No vehicle breakdown cover for vehicles going off the UK mainland.
