Ofcom said that, from today, landline and mobile charges are clearer for calls starting 084, 087, 09 and 118.
The telecoms regulator said that people in the UK spend 250 million hours phoning these service numbers and that amounts to £900 million in charges.
From today, charges for the service numbers will consist of an access charge for the phone number and a service charge set by the organisation or company being called – the service provider.
These service providers will have to tell customers how much the service charge is when it advertises or otherwise mentions the phone number.
Ofcom said that because of these new rules many organisations that used 084 and 087 numbers will move to using 03 numbers – these don’t cost any more to 01 or 02 numbers.
