The Special Charges Code of Practice currently says this...
"Calls to directory numbers are charged at £2 per minute, except calls to 118402 which are charged at just £1 per minute."
However, the price list page offers up this additional information...
Directory Enquiries starting 118 cost £2 to £4 per minute.
Calls to 118402 are charged £1 per minute.
More information on £4 charges click here
Please add the additional information about directory enquiry numbers charged at £4 per minute to the Code of Practice page.
Without the fix, around 80 DQ numbers are advertised as costing £2 per minute but actually cost £4 per minute.
