When am I first billed?
Nothing is taken at checkout — billing starts once the service is live.
Nothing at checkout
No payment is taken when you place the order. Your Direct Debit is set up ready, but it isn't used until the network activates the connection.
The first bill
The first bill usually covers a part month from your activation date plus the first full month in advance. That makes it larger than a typical monthly bill — after that, bills settle into a regular monthly amount.
Ongoing bills
Bills are collected monthly by Direct Debit. You'll be told the amount and the collection date in advance.
