You can track your mileage against the mileage you declared in the Ticker app.
We'll let you know if you're getting close to the mileage you declared, and you can just update that yourself in the Ticker app. You'll get a quote to check what you need to pay, then make the change right then and there. Easy. Please be aware there is a maximum amount of mileage we will cover. If you reach this limit you may not be able to add more. We can discuss what options there are when you chat to us.
