How data is assured internally
While producing a comprehensive and balanced performance report is important, it is not enough on its own. We need to make sure that all data is robust. To assure our data, we have gone beyond the practice of relying solely on automatic systems as a means of control. Instead, we have established a company assurance and data control management role within our Business Performance and Internal Control team. That role reviews evidence and checks and challenges data across our business. We also employ external assurance providers to carry out additional annual checks on our systems and data.
Our report has been independently assured by DNV GL. The assurance was conducted in accordance with the AccountAbility Assurance Standard (AA1000AS) (2008), Type 2 assurance. This looks at how we follow the principles of inclusivity, materiality and responsiveness in our reporting. It also considers the reliability of performance information.
