"Top Up" Miles are additional Miles you can buy if you need more Miles (on top of your "Policy Miles" and "Reward" Miles). You can buy "Top Up" Miles in bundles of 250, 500, 1000 Miles at any time during the term of your policy. The cost of "Top Up" Miles depends on the price of your policy - this is called your cost per mile rate and it was set when you took out your policy, changed your details, or when you renewed. Your cost per mile rate can be viewed on the "Top Up Station" page of MyBoxyMo, and you can see the price of your "Top Up" Miles bundles on the Top Up Miles page. You can buy Top Up Miles online via the Top Up Miles page on MyBoxyMo, or by phone on 1890 000 000. If you don't use up all your "Top Up" Miles, you can roll them over to your next renewal (although they can't be refunded if you do not renew).
