The price of a BeRebel policy is partly fixed at the beginning of the month and partly variable at the end of the month.
The fixed monthly price can only increase if the previous Commercial Offer has expired or if the characteristic parameters of the tariff have changed (e.g. technical data of the vehicle, Bonus/Malus class, change of residence of the owner, etc.). The variable part normally changes from month to month, as it depends on the km driven.
