The story

Research in the company was first established in 1921 at the Post Office Research Station at Dollis Hill, London. In 1968, BT began the move of its research to the new site at Martlesham Heath in Suffolk. By late 1969, small teams of researchers were working at Martlesham. The first new research building was formally opened on 21 November 1975 by Queen Elizabeth II of the United Kingdom. The architect was Stanislaw Spielrein of the Ministry of Public Building and Works. The new building housed 1,700 people.

Location

BT's main research facility is located at Adastral Park, near Ipswich in Suffolk, England. The Adastral Park site was first planned around 1968 as the Martlesham Heath Post Office Laboratories and after completion in 1971 it has grown to a facility which today has around 4,000 research and development people from both BT and some of its partner companies. Globally, BT has additional research labs in Beijing, Boston MA and Abu Dhabi. The focus of research at BT is information and communications technology.

The Royal Air Force were the original residents of the site in Suffolk at RAF Martlesham Heath. Experimental aircraft test flights flew from the airfield and the name (Adastral Park) is intended to reflect the history of experimentation and innovation, which is the continuing focus for the Park. The initial models and plans created by the Ministry of Public Building and Works (the successor to the Ministry of Works) would appear to indicate the influence of the Thunderbirds TV series of the 1960s.

Academic research partners

BT works closely with both academics and students in over 20 institutions globally and has strong partnerships with the University of Cambridge in the UK, the Massachusetts Institute of Technology in the US and Tsinghua University in China. BT also leads the India-UK Advanced Technology Centre, a consortium of 22 Indian and UK industry and academic partners conducting research into current and next generation fixed and wireless communications.
