Institution of Engineering and Technology

The Institution of Engineering and Technology (IET) is a multidisciplinary professional engineering institution. The IET was formed in 2006 from two separate institutions: the Institution of Electrical Engineers (IEE), dating back to 1871, and the Institute of Incorporated Engineers (IIE), dating back to 1884. Its worldwide membership is currently in excess of 156,000 in 148 countries. The IET's main offices are in Savoy Place in London, England, and at Futures Place in Stevenage, England.

In the United Kingdom, the IET has the authority to establish professional registration for the titles of Chartered Engineer, Incorporated Engineer, Engineering Technician, and ICT Technician, as a licensed member institution of the Engineering Council.

The IET is registered as a charity in England, Wales and Scotland.

Discussions started in 2004 between the IEE and the IIE about merging to form a new institution. In September 2005, both institutions held votes of the merger and the members voted in favour (73.5% IEE, 95.7% IIE). This merger also needed government approval, so a petition was then made to the Privy Council of the United Kingdom for a Supplemental Charter, to allow the creation of the new institution. This was approved by the Privy Council on 14 December 2005, and the new institution emerged on 31 March 2006.

The IET is the result of mergers and absorptions between over forty institutions since 1871.

The Society of Telegraph Engineers (STE) was formed on 17 May 1871, and it published the Journal of the Society of Telegraph Engineers from 1872 through 1880. Carl Wilhelm Siemens was first President of IEE in 1872. On 22 December 1880, the STE was renamed as the Society of Telegraph Engineers and of Electricians and, as part of this change, it renamed its journal the Journal of the Society of Telegraph Engineers and of Electricians (1881–1 82) and later the Journal of the Society of Telegraph-Engineers and Electricians (1883–1888). Following a meeting of its Council on 10 November 1887, it was decided to adopt the name of the Institution of Electrical Engineers (IEE). As part of this change, its Journal was renamed Journal of the Institution of Electrical Engineers in 1889, and it kept this title through 1963. In 1921, the Institution was Incorporated by royal charter and, following mergers with the Institution of Electronic and Radio Engineers (IERE) in 1988 and the Institution of Manufacturing Engineers (IMfgE) in 1990, it had a worldwide membership of around 120,000. The IEE represented the engineering profession, operated Professional Networks (worldwide groups of engineers sharing common technical and professional interests), had an educational role including the accreditation of degree courses and operated schemes to provide awards scholarships, grants and prizes. It was well known for publication of the IEE Wiring Regulations which now continue to be written by the IET and to be published by the British Standards Institution as BS 7671.

The modern Institution of Incorporated Engineers (IIE) traced its heritage to The Vulcanic Society that was founded in 1884 and became the Junior Institution of Engineers in 1902, which became the Institution of General Technician Engineers in 1970. It changed its name in 1976 to the Institution of Mechanical and General Technician Engineers. At this point it merged with the Institution of Technician Engineers in Mechanical Engineering and formed the Institution of Mechanical Incorporated Engineers (IMechIE) in 1988. The Institution of Engineers in Charge, which was founded in 1895, was merged into the Institution of Mechanical Incorporated Engineers in 1990.

The Institution of Electrical and Electronic Technician Engineers, the Society of Electronic and Radio Technicians, and the Institute of Practitioners in Radio and Electronics merged in 1990 to form the Institution of Electronics and Electrical Incorporated Engineers (IEEIE).
