At one time, I think that the answer was a resounding 'yes'.

Now you may still save on a longer call, which 0870s tend to be. Definately use BT during the weekday evening and weekend.

During the weekday daytime BT charges 7p/min charged to the nearest second with a 3p connection charge. 18185 charges 6p/min charged to the next whole minute with a 4p connection charge.

By charging to the nearest whole minute rather than second, the charge for the call will be, on average, longer by half the length of 1 minute charge. As an example, see here. This is for BT's charges of geographical numbers and shows how changing from per second billing to per minute has actually increased charges.

try using 18185's London access number instead - 4 pence a minute
