NPL provides the measurement capability that underpins the UK’s prosperity and quality of life.

The National Physical Laboratory (NPL) is the UK’s National Metrology Institute (NMI), developing and maintaining the national primary measurement standards, as well as collaborating with other NMIs to maintain the international system of measurement. As a public sector research establishment, we deliver extraordinary impact by providing the measurement capability that underpins the UK’s prosperity and quality of life. We develop the metrology required to ensure the timely and successful deployment of new technologies and work with organisations as they develop and test new products and processes.

In this digital age, our world-leading measurement science provides confidence in data, which enables innovation and international trade to flourish. We align our capabilities with the most important national challenges like energy, health, security, net zero and the prosperity of the nation, and lead major national programmes that deliver impact across the UK.
