Ofcom is to review the cost of calling some telephone services, to ensure people are protected from high prices and unfair practices. People have been spending less on mobile and landline calls in recent years, and consumers generally have a wide choice of call packages and phone services.

However, Ofcom is concerned about the rising costs of calling certain telephone service numbers. These include directory enquiries numbers, which begin with 118; and ‘personal’ or ‘follow-me’ numbers, which begin with 070 and allow users to be contacted on any phone at any location. Given the rising cost of calling these service numbers, Ofcom is launching a Call Cost Review, to ensure that prices are transparent and fair to consumers.

118 numbers were introduced by Oftel, the previous telecoms regulator, in 2003. The directory enquiry market, then run entirely by BT, was opened up to competition and a wide range of competing 118 services were launched. There are more than 400 directory enquiry services offering a variety of options and prices, with call costs ranging from 35p per call to £9 and higher.

Ofcom has been monitoring the costs of the more expensive services, which have risen significantly in recent months as fewer people use these services. 070 numbers were introduced by Oftel in 1995. They are designed to be used as a ‘follow me’ service, where calls are diverted from one number to another, so that the person being called can keep their own number private, and remain contactable wherever they go. Small businesses and sole traders often use them to make it easy to manage calls.

070 numbers are also sold legitimately on a one-off basis – for example, when someone is buying or selling a car, and does not wish to advertise their private mobile or fixed line number on a website or magazine.

However, 070 numbers may be confused with mobile phone numbers, which also start ‘07’. Ofcom is concerned about evidence of scams designed to make consumers believe they are calling a mobile number. When people call the 070 number back, they are actually dialling a service costing up to £3.40 a minute.

Our Call Cost Review will consider whether consumer harm is arising out of deliberate misconduct or market failure, and what action may be required. We expect to publish detailed proposals later this year. We are also talking to the Phone-paid Services Authority about whether there are any additional consumer protection measures it could consider under its Code of Practice.
