THE DVLA is among 30 organisations named and shamed by a leading consumer watchdog for making money from customers through premium-rate helplines.
Among those identified by research published today in Which? magazine are the DVLA in Swansea and Admiral Insurance of Cardiff.
The DVLA made £3.4m from its 0870 number in the last financial year.
The organisation has promised to switch to a cheaper number, but has not said when, says Which?
Other leading UK firms accused of making money at the expense of their consumers include Tiscali, British Gas and Barclays Bank.
All use higher-charging 0871, 0870, 0844 or 0845 numbers for customer service or technical support lines. Organisations that use these numbers can share the revenue from calls with the phone service provider, so the longer a customer stays on the line the more the organisation earns.
Communications regulator Of- com introduced 03 numbers last year, which cost the same as a geographic (01 or 02) number.
The watchdog plans to stop organisations making money from 0870 numbers. But none of the organisations checked by Which? had switched to 03.
A DVLA spokesperson said the organisation had planned to introduce 03 numbers by January 31 this year.
But Ofcom opted for a further period of consultation, due to end on June 16.
