The National Physical Laboratory (NPL) is the national measurement standards laboratory for the United Kingdom, based at Bushy Park in Teddington, London, England. It is the largest applied physics organisation in the UK.
NPL is known for its UK leadership in measurement and materials science. Since 1900, when Bushy House was selected as the site of NPL, it has developed and maintained the primary national measurement standards. Today it provides the scientific resources for the National Measurement System financed by the Department for Business, Innovation and Skills.
NPL also offers commercial services, applying scientific skills to industrial measurement problems, and manages the MSF time signal. The NPL cooperates with professional networks such as those of the IET to support scientists and engineers involved in those areas in which NPL has expertise.
Teddington was also home to the UK National Chemical Laboratory but this was closed in 1965 and some of its work was transferred to NPL.
The laboratory was initially run by the UK government, with members of staff being part of the civil service. Administration of the NPL was contracted out in 1995 under a GOCO model, with Serco winning the bid and all staff transferred to their employ. Under this regime, overhead costs halved, third party revenues grew by 16% per annum, and the number of peer-reviewed research papers published doubled. It was decided in 2012 to change the operating model for NPL from 2014 onward to include academic partners and to establish a postgraduate teaching institute on site. The date of the changeover was later postponed for up to a year. The candidates for lead academic partner were the Universities of Edinburgh, Southampton, Strathclyde and Surrey with an alliance of the Universities of Strathclyde and Surrey chosen as preferred partners. The laboratory transferred back to Department for Business, Innovation and Skills ownership on 1 January 2015.
NPL was initially sited entirely within Bushy House but grew to fill a large selection of buildings on the Teddington site. Many of these buildings were demolished and the work moved to a large state-of-the-art laboratory for NPL that was built between 1998 and 2007. The construction and operation of this new building were initially being run under a PFI scheme, before transferring back to the DTI in 2004 after the private sector companies involved made losses of over £100m.

Researchers who have worked at NPL include: D. W. Dye who did important work in developing the technology of quartz clocks. The inventor Sir Barnes Wallis did early development work there on the "Bouncing Bomb" used in the "Dam Busters" wartime raids. H.J. Gough, one of the pioneers of research into metal fatigue, worked at NPL for 19 years from 1914 to 1938. Sydney Goldstein and Sir James Lighthill worked in NPL's aerodynamics division during World War II researching boundary layer theory and supersonic aerodynamics respectively. Dr Clifford Hodge also worked there and was engaged in research on semiconductors. Others who have spent time at NPL include Robert Watson-Watt, generally considered the inventor of radar, Oswald Kubaschewski, the father of computational materials thermodynamics and the numerical analyst James Wilkinson.
NPL research has contributed to physical science, materials science, computing, and bioscience. Applications have been found in ship design, aircraft development, radar, computer networking and global positioning.
The first accurate atomic clock, a caesium standard based on a certain transition of the caesium-133 atom, was built by Louis Essen and Jack Parry in 1955 at NPL. Calibration of the caesium standard atomic clock was carried out by the use of the astronomical time scale ephemeris time (ET). This led to the internationally agreed definition of the latest SI second being based on atomic time.
NPL has undertaken computer research since the mid-1940s. From 1945, Alan Turing led the design of the Automatic Computing Engine (ACE) computer. The ACE project was overambitious and floundered, leading to Turing's departure. Donald Davies took the project over and concentrated on delivering the less ambitious Pilot ACE computer, which first worked in May 1950. Among those who worked on the project was American computer pioneer Harry Huskey. A commercial spin-off, DEUCE was manufactured by English Electric Computers and became one of the best-selling machines of the 1950s.
Beginning in the mid-1960s, Donald Davies and his team at the NPL pioneered packet switching, now the dominant basis for data communications in computer networks worldwide. Davies designed and proposed a national data network based on packet switching in his 1965 Proposal for the Development of a National Communications Service for On-line Data Processing. Subsequently, the NPL team (Davies, Derek Barber, Roger Scantlebury, Peter Wilkinson, Keith Bartlett, and Brian Aldous) developed the concept into a local area network which operated from 1969 to 1986, and carried out work to analyse and simulate the performance of packet switching networks. Their research and practice influenced the ARPANET in the United States, the forerunner of the Internet, and other researchers in the UK and Europe.
