The number of devices on Camden Council's network under its 'Bring Your Own Device' (BYOD) scheme has jumped from 74 in 2012 to 171 in 2013 to 252 today to reach an underwhelming 4 percent of the workforce.
The figures, which were released under the Freedom of Information (FoI) Act, show that the authority's employees overwhelmingly prefer Apple products, with the BYOD scheme operating 132 personal iPhones and 60 iPad tablets.
Rival Samsung lags behind with 45 devices in use at the council. There are also a small number of devices from Motorola, HTC, Sony, Nexus and Psion according to the response to the request, which was submitted by UK think tank Parliament Street.
Camden Council is part way through executing an IT strategy published in 2012 which promised to encourage and support flexible working, led by CIO John Jackson.
The strategy aims to save at least £120 million up to 2018 and make access to the council's IT systems available from any device in any location.
Camden Council has 6,000 staff and serves an area of 22 square kilometres with a population of 217,000.
A Socitm report published at the end of last year predicted that BYOD will grow in local public services despite restrictions presented by central government regulations, such as compliance with the Public Sector Network (PSN).
The report said that many local authorities have already brought in BYOD policies in order to save money plus increase productivity and efficiency, but also because employees are increasingly demanding to use their own (often superior) technology for work.
Socitm particularly pointed to councils in Leeds, Solihull, and Stoke-on-Trent for their pioneering BYOD policies.
"Introducing BYOD policies is a highly effective strategy for councils to simultaneously save money whilst improving mobility of the workforce," said Patrick Sullivan, CEO of the Parliament Street think tank.
