Our History

The business was founded in 1920 and is one of a select few high technology organisations with an enduring pedigree.


ERA, now part of the edif Group, was originally incorporated under the name “The British Electrical and Allied Industries Research Association” but it was generally known as “The Electrical Research Association” or “ERA”. Initially, ERA’s funding came jointly from the government, through the Department of Scientific and Industrial Research, from industry and from the subscriptions of member companies. Prior to ERA, there had not been any facility solely dedicated to co-operative electrical research in the UK although some research was carried out by a few manufacturers, suppliers and larger users of electricity. ERA filled the recognised gap in the organisation of the industry by supplying research and technology innovation.


During the 1939-1945 war, direct assistance to the war effort was given by ERA: this assistance was recognised by the Ministry of Labour in 1941 as an ‘essential undertaking’. ERA’s activities during the war included working on the development of radar and mine detection equipment. Major new laboratories and offices were opened in Leatherhead, Surrey, in 1957 which have remained the headquarters of the organisation ever since. Development on the 15-acre campus site has continued to the present day with the addition of several large purpose-built facilities.


Until the late 1960s, ERA had derived much of its income from member company subscriptions and UK government grants. After 1969, ERA began re-organising its mode of operation to reflect the rapidly changing technology base within the industries it served. This enabled the company to derive income from single client and multi-client projects. Thus, ERA became the first ‘privatised’ research association.


In September 1979, ERA formally changed its name from The Electrical Research Association Ltd to its present name, ERA Technology Ltd. During the 1970s, 1980s and 1990s, ERA 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 cutting edge of technology.


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.  In September 2003, the company announced the agreement to sell the entire issued share capital of ERA Technology to Cobham Plc. In February 2011, the engineering consultancy business of ERA Technology Ltd (ERA) was acquired from Cobham plc by edif Group (a company backed by Phoenix Equity Partners, a leading UK mid-market private equity investor).


Following this transfer of ownership in 2011, ERA made acquisitions of its own. In 2013, Earthing Solutions Limited, (previously trading as Earthing Measurements Limited and Strategy & Solutions Ltd), became part of ERA’s expanding profile. Earthing Solutions Ltd is a leading UK technical consultancy focussing on site-based activities and specialising in Power System Earthing (PSE) measurements, design, rise of earth potential (ROEP) assessment, policy, training and research and development. Since its inception in 1991, it has provided support to both the UK Distribution Network Operators (DNOs) and the wider electricity distribution, transmission and generation industries. This extensive work has helped Earthing Solutions to secure a position as one of the most respected earthing consultancies in the UK and beyond.
