The de-regulation of the telecoms market, which followed privatisation, opened up the market to rival suppliers, and with the application of new technology, barriers to entry fell appreciably.
The network now can be used by other firms through a process called Wholesale Line Rental (WLR).
After being threatened with brake-up BT created its own independent division, Openreach, in 2004 to try to ensure fair access to its network for rival operators.
In 2005 Ofcom set an RPI - X pricing formula for BT's charges for the use of its network to encourage rivals to enter the market. By 2006 over 300 independent firms had access to the network infrastructure, making the UK telecoms market one of the most competitive in the world.
Even so, Ofcom has requested that BT speeds up its unbundling process, and has focussed a large part of its investigation on BT’s broadband pricing.
Today, the market can best be described as an oligopoly, with a three-firm concentration ratio of 89%.
