National Physical Laboratory

The National Physical Laboratory (NPL) is the UK's national measurement institute, based in Teddington, south-west London. It is a government-owned facility operated by DSIT (the Department for Science, Innovation and Technology) and is responsible for maintaining the UK's primary measurement standards across physics, chemistry, engineering, and digital metrology. NPL develops and disseminates the measurement Science that underpins manufacturing, telecoms, finance, and infrastructure sectors.

NPL's work reaches into maritime and transport autonomy through its expertise in timing, positioning, and sensor calibration, all of which are critical to autonomous navigation. On 4 June 2026, NPL co-published the first official measurement of the UK maritime-autonomy sector alongside Lloyd's Register and the National Shipbuilding Office, with research by Stehr Consulting. The report established current annual turnover at £600 million and approximately 5,000 jobs, projecting £8.3 billion GVA by 2050 under a central scenario and £26.5 billion in the high-growth case .

NPL's role as a co-author of an economic baseline rather than a purely technical report signals the government's intent to treat maritime autonomy as a sector requiring both measurement rigour and industrial policy. Its involvement gives the figures a methodological credibility that a consultancy report alone would not carry.

NPL co-authored the first official UK maritime-autonomy economic baseline published on 4 June 2026, alongside Lloyd's Register and the National Shipbuilding Office. The report, researched by Stehr Consulting, quantified current sector turnover at £600m and ~5,000 jobs, with a central projection of £8.3bn GVA by 2050 and a high-growth scenario of £26.5bn and 39,200 jobs . NPL's involvement anchors the methodology in national measurement standards, providing independent statistical credibility alongside the commercial imprimatur of Lloyd's Register.
