Beware of admin charges for road traffic offences! We hired a car through green motion and forgot to pay the DART charge (£2.50). We received an £84 admin charge from green motion for sending us an email informing us about the charge and the fact they had passed our details onto the DART team who would charge us separately for the actual missed charge (another £80). Although we were totally in the wrong forgetting about the charge, the £84 is a ridiculous fee bearing in mind the level of admin effort green motion put in. For comparison we’ve also done the same thing with Avis who just paid the charge on our behalf - no fines, no charges. Such a better service.
