Our main activities are the provision of fixed telephony lines and calls, broadband, mobile and TV products and services as well as managed networked IT services.
In the year ended 31 March 2014 (the 2013/2014 financial year) BT Group revenue was £18.3 billion with £9.7 billion of this derived from next generation products and services, primarily ICT and managed networks, broadband, TV, and convergent mobility solutions. UK operations accounted for 77% of revenues and here BT is the largest communications services provider, with around 10 million voice lines, around 7.3 million retail broadband customers, a TV base of 1 million customers and over 5 million wifi hotspots. We also provide network services to other licensed operators. For further details see http://www.bt.com/.
BT’s main research and development centre is in Adastral Park in Suffolk, UK, and is home to over 3,800 of BT’s top scientists, engineers and business people. Our employees include many who are world leaders in their specialist fields, working at the forefront of new technologies and standards development in areas such as broadband applications and services, IP and data networks, IT, mobility and converged services, network design and management, and business applications and services. We provide research, development and consulting services for BT, developing innovative technological ideas and solutions that translate into practical and marketable solutions for the business. Our research labs played a leading role in the development of global communications standards and we inherit from them a science and engineering base acknowledged widely as second to none.
BT invested £530 million in research and development in 2013/2014 to support our drive for innovation. Our global development centres, located in the UK, US and Asia, help us draw together key and complementary skills and resources with the objective of increasing agility, efficiency and delivery of innovation to the market.
