If you use more than the monthly bandwidth allowance included in your plan, you will simply be invoiced for the extra bandwidth used. The price depends on which plan you are on, and is charged incrementally. So if you use 5.1GB and are on the Standard Plan, you would just pay £0.50 for the extra 0.1GB.
