Guide: How do I get to the 'Download Bill' page?
If your account looks different, you could be on the new 360 platform (https://community.o2.co.uk/t5/Welcome-News/O2-System-Updates-360/m-p/1598402 )
In that case, once you log in there click on the "My o2" on the left (under the o2 sign on the blue banner).
Then choose either "Latest Bill" or "Billing History" in the 3rd column.
Billing history is probably best. From here you can scroll down to the bill you wish to see, and either click "view bill" which opens a new page with the bill details or "download PDF" if you want to keep a copy.
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
