0844 numbers are almost never included in any 'free' minutes or talktime included in a phone package. From a BT landline, an 0844 number will typically cost up to a maximum of 5p per minute to call.
The cost of calling 0843, 0844 and 0845 numbers is made up of two parts: an access charge going to your phone company, and a service charge set by the organisation you are calling. The service charge for calls to 084 numbers is between 0p and 7p per minute.
