We are accredited with the British Standards Institute (BSI) for both quality management and environmental management. The ISO (International Organisation for Standardisation) standards are internationally recognised and are instrumental in making trade between countries possible. Our quality management accreditation, ISO 9001:2015, demonstrates that we meet a number of strict quality management principles including a strong customer focus, the motivation and implication of top management, the ‘process approach’, and a commitment to continual improvement. We take the quality of our products and services, and your experience with us incredibly seriously, something which ISO 9001:2015 represents. We regularly carry out internal audits to ensure that we continue to meet the standards this accreditation demands, and to guarantee that you continue to receive products and services of the very highest standard.

International Laboratory Accreditation Cooperation

One of the most prestigious accreditations to our name, we became one of only five UKAS (United Kingdom Accreditation Service)-accredited acoustic calibration labs in 2018. As a UKAS-accredited calibration laboratory, we are capable of calibrating sound level meters and acoustic calibrators to the very latest and highest standards, as well as octave band filters. UKAS standards are internationally recognised, as demonstrated by our association with ILAC (International Laboratory Accreditation Cooperation). ILAC is an internationally-recognised organisation for accreditation bodies. Having the ability to calibrate acoustic instruments to UKAS-accredited standards is incredibly important, as it demonstrates our commitment to quality. Becoming a UKAS-accredited calibration lab is no mean feat; any institution that wishes to become accredited must undergo a thorough verification process. We have our own designated UKAS calibration lab and all the testing equipment used in the lab has been thoroughly checked by the UK Accreditation Service.
