On "BT Basic" 03 numbers are inclusive in the call allowance at all times, whereas 0845 numbers are not.

I suspect that you are on "BT Unlimited Weekend Calls". If you only use the phone at weekends, then you will be able to make unlimited calls to 01/02/03 numbers (including 0345) during this time. BT also includes calls to 0845 numbers because all subscribers contribute towards the 'Service Charge', whether they call these numbers or not. You will pay penalty charges for making calls to ordinary numbers at other times.

Sadly many BT customers fail to recognise that the cheapest of its call plans is only suitable for those who only make calls at the weekend (or none at all). The penalty charges on weekday calls very quickly overtake the higher monthly charge for the other plans, e.g. as little as one 10-minute call and one 5-minute call to any 01/02/02 number(s), before 7pm on a weekday, each week justifies the subscription to the Unlimited Anytime Plan.

Because the BT penalty charge for calling 0845 numbers is bizarrely less than that for calling 01/02/03 numbers "out of plan", at present, businesses are justified in retaining 0845 numbers as an option for those who are calling outside the terms of their selected plan - they are however probably paying far too much for their ordinary telephone calls!

This messy situation will probably continue until June 2015, when the special regulations which apply to BT will be lifted and a new regulatory regime for all 08 numbers will be introduced.

Yes I am 

I expect there are still lots of outstanding bank debit cards which list the 0845 number on them, so I doubt the withdrawal of these numbers will happen for some time yet.
