Ofcom's Business Connectivity Market Review examines the markets for the provision of leased lines to businesses in the UK.
Leased lines are high-quality, dedicated, point-to-point data transmission services used by businesses and providers of communications services. As well as being essential components of many businesses communications systems, they are also essential to support the provision of mobile telephone and fixed residential broadband services.
Every three years, Ofcom conducts a review of competition in the markets for the provision of leased lines in the UK. Where we find that a provider has "significant market power" (SMP) in a market (i.e. that they are able to act independently of competition) we impose regulations designed to address concerns about the impact of that market power on competition.
