There's no need to operate a free-to-caller 0800 or 0808 number. Swapping the premium rate 0844 number over to the matching 0344 number would be enough. The BBC did this some time ago, with 084 and 087 numbers being replaced by the matching 034 or 037 number.
Calls to 03 numbers are inclusive from landlines and mobiles, else charged at 'geographic rate' - the same as calling 01 and 02 numbers. More than 95% of calls made to 01, 02, and 03 numbers are now made as part of an inclusive call allowance with each such call attracting no additional charge.
A non-geographic number is simply a fancy call-handling and call-forwarding system. When an organisation chooses to use a non-geographic number, there are additional charges for call-handling and call-forwarding that need to be paid. For high volume users this can be as low as 0.3p per minute.
When an 03 number is used, the called party pays the call-handling and call-forwarding fee and the caller pays their landline or mobile provider the same as whatever they pay for calls to 01 and 02 numbers. Revenue sharing is not allowed on 03 numbers.
When an 084, 087 or 09 number is used, the caller pays the call-handling and call-forwarding fee through the declared Service Charge with the remainder being paid out to the called party as revenue share. TalkRadio likely earn about 3p to 4p per minute from incoming calls. The caller is also hit by their provider's Access Charge (up to 12p per minute from landlines or up to 55p per minute from mobiles).
When an 080 number is used, the called party pays the call-handling and call-forwarding fee but also has to compensate the caller's landline or mobile provider for carrying the call as the caller paid nothing. This additional Call Origination Fee can be as high as 8p per minute for calls originating from a mobile phone.
Usage of an 080 number means that the caller's provider is paid by the called party for a call that would otherwise have counted towards the caller's monthly inclusive allowance had an 03 number been employed.
