You're sort of right there Barbara.
Since BT reduced the cost of calling 0845 numbers on 1st August last year, it
is actually cheaper for someone on BT Together Option 1 (now called the Unlimited Weekend Plan)
and using BT to make their calls to call an 0845 number as opposed to a geographical (01 or 02) or 03 number. As dorf says though, a lot of people use other calls providers these days and some of them charge more than BT for 0845 calls.
Comparative costs are currently:
01/02/03 - 6p connection + 3.25p per min. peak, 4.5p for up to an hour evenings and weekend.
0845
-----
- 6p connection + 2p per min. 6am to 6pm, ½p per min 6pm to 6am (7 days a week)
From 1st April costs will be:
01/02/03 - 6p connection + 4p per min. peak, 1.5p per min. evenings and free at weekends (up to an hour).
