Nuisance call protection: what your phone company charges For most providers, services such as caller display and the voicemail service 1571 are free for customers. However, from January BT customers will be charged £1.75 a month to use its caller ID service, which helps people manage nuisance calls by displaying the caller's number when the phone rings. Customers will only be exempt from the charge if they take out a 12-month contract. Sky and TalkTalk do not charge for the service, but Virgin charges £2.25 a month. BT is the most expensive provider for enhanced services like incoming call blocking and anonymous call rejection. It charges customers £3.90 a month for incoming call blocking, which blocks selected numbers, compared to £2.50 for KC and £3.25 for TalkTalk. The service is not available for EE and some Virgin Media customers. BT charges nearly £5 for its service to stop calls from anonymous or withheld numbers. Virgin Media charges just £2.70 and KC customers can get the service for free. But BT is among the cheaper providers for the enhanced 1571 voicemail service, charging £1.75. Post Office and TalkTalk are the most expensive at £2.55. MPs have called on Ofcom to take increased action against nuisance calls. The Culture, Media and Sport committee chairman John Whittingdale said such phone calls were a "source of irritation and distress to millions." More than three million adults have been left afraid to answer the phone as a result of nuisance calls, according to a study by debt charity StepChange. A BT spokesman said: "BT takes the issues of nuisance calls very seriously." The spokesman said BT had invested in the BT6500 phone, costing £34.99, which protects customers from nuisance calls. BT customers can also rent the phone for £2.49 a month. Gillian Guy, chief executive of national charity Citizens Advice, said: "Services to help consumers protect themselves against these nuisance calls can make a difference, but what we really need to see is tough action from the Government to crack down on cold calling pests once and for all. I want to see a ban on cold calling by financial service firms, which would cut the number of calls and help consumers to know that a company which called them out of the blue was not to be trusted.
