ISO 17025 accreditation in London at a glance
London has an unusual neighbour for its laboratories: the National Physical Laboratory at Teddington, the UK's national metrology institute. Commercial testing and calibration laboratories in the capital work in its shadow, and customers expect their results to be traceable. ISO/IEC 17025 sets out the competence, impartiality and consistent operation of testing and calibration laboratories, including method validation, traceability and measurement uncertainty; accreditation is granted by the national accreditation body. Sterling's London office supports the preparation, with Effivity and Sterling Academy included with the engagement; accreditation itself is granted by the national accreditation body. National law, regulators and accreditation detail sit on the United Kingdom page rather than here.

ISO 17025 in London: questions clients ask
Why is traceability to NPL relevant for London laboratories?
Because the National Physical Laboratory at Teddington is the UK's national metrology institute, so many calibration chains in the capital end there. A laboratory seeking accreditation must show traceable measurement and an uncertainty budget. Accreditation is awarded by the national accreditation body, described on the UK page.
Is ISO 17025 certification or accreditation?
It is accreditation: a laboratory is assessed against ISO/IEC 17025 by the national accreditation body, which confirms technical competence for defined methods. Sterling supports preparation of the quality system and technical records. Customers and regulators then rely on the accreditation schedule to see what is covered.
