Hi @NeilAPS 

Calls to 03 and 070 numbers cost the same as other standard fixed line numbers starting 01 or 02, and are included in your minutes and texts as part of your tariff.

Edited to add, I have noticed you have posted in the business section so if you are a business customer the charges are different...see here.
