1st Bill

[Max_P]

I took out a new contract with o2 via a 3rd party after being on a sim only deal, I have been charged my new monthly fee plus a month in advance, so £21x2 for the 1st bill. Has anybody had the same experience? I have been with o2 a long time and never had this happen before

Yes, that's normal.

Does this apply even if I am not a o2 Business Customer?

Yes all explained here

You shouldn't have got 2 full bills but you do pay a month in advance

You’ll get your first bill within four days of joining O2, and you’ll be charged 14 days after you receive it. Your official billing date is usually the date you joined us, and it will be the same every month.

If you joined us on the 29th, 30th or 31st of the month, your official billing date will be the 1st of the following month. Your first bill will be pro rata, which means that we’ll charge you for one full month’s airtime, as well as any airtime you use in those first few days before your billing cycle starts.

 If you’ve upgraded your device, your billing date will stay the same. Your next bill will be pro rata and might include a charge from your old tariff or airtime charges.

You can view this on your ‘Summary of Charges’ page in My O2, where you can see your total bill broken down by:

The first part of the bill is proo rata for the rest of the current month and the second part the advanced payment.

All explained in the link I posted and it's the same for all customers.
