ISO 9001 is the world’s most recognised quality management system standard, established by the International Organization for Standardization (ISO). It helps organisations develop and improve performance and demonstrate high levels of service quality. Certification follows the successful completion of an audit against the ISO 9001 standard. ISO 9001 helps organisations implement clear, repeatable processes to maintain a quality service for their customers.

The United Kingdom Accreditation Service (UKAS) is the national accreditation body for the United Kingdom. The government appointed it to assess organisations that provide certification, testing, inspection, and calibration services.
