All you need to know about how top up miles work.
You can track the miles you have driven and your score in your app or dashboard. This will also estimate how many miles you are likely to drive in your policy year. Don't worry if you run out of miles, you can top up at any time.
The cost of top up miles is based on your driving score – the safer you drive, the cheaper your miles will be.
However, remember to estimate your miles as accurately as you can from the start as topping up can be a more expensive option.
