ERA Technology Limited was the successor company to the British Electrical & Allied Industries Research Association, known as the Electrical Research Association. ERA Technologies Limited was succeeded by ERA Foundation Limited.

During the 1970s, 1980s and 1990s ERA Technology Limtied continued to grow and develop into new research areas, including RF technology and electronic systems. It also expanded into providing a wide range of engineering consultancy services for mechanical as well as electronic and electrical systems. In doing so it established itself as one of Britain's leading independent consulting organisations at the leading edge of technology development. In January 2001, the entire organisation was transferred to a new trading company, limited by shares. The original company, still limited by guarantee, was renamed The ERA Foundation. The trading operation, retaining the name ERA Technology, was run as a wholly commercial enterprise, responsible to its shareholders.
