Since the deregulations of the telecommunications market in the late 1980s, and as new technologies have been entering the market, telecom providers in the UK have kept mushrooming. Business customers are key sources of revenues for these companies, and allow several niche customers, thriving on a specific technology product or geographical area, to coexist with large national telecom providers in the UK.

Major telecom providers in the UK have at some point all been providing landline, mobile and broadband internet services to businesses and/or private customers. The problem is that decades of mergers, demergers and various capital operations have made their product portfolio change many times. Here’s what we know about these major brands as far as business services are concerned, and as of early 2016.

Here is the comprehensive list of all Telecommunications Companies in UK, their addresses (postal and physical), contacts (telephone and e-mail) and a link to the Telecommunications Companies in Britain websites.
