Link-Up is recognised as a compliant provider of the Sentinel audit standard

Our Link-Up community offers a tailored approach to supplier assurance whilst ensuring that your suppliers are fully compliant with specific industry requirements, such as Sentinel. Being the premier safety systems in use across the rail industry, Sentinel assessments offer rail suppliers the opportunity to work trackside across the UK by demonstrating their compliance through our Link-Up questionnaire.

Quality Management throughout your supply chain is of paramount importance for organisations looking to maintain competitive advantage, reduce costs, grow their business and always strive for continuous improvement. Maintaining a certified Quality Management Systems (QMS) can help minimise the number of quality issues in your goods and services, while mandating them in your supplier requirements ensures the rest of your supply chain understands the importance of internal controls and how adhering to the highest standards of quality is integral.
