Supplier Handbook Summary
SNG is committed to preventing modern slavery in its operations and supply chains, adhering to the Modern Slavery Act 2015. Suppliers must ensure their operations are free from modern slavery, be transparent in their supply chains (publishing a statement if turnover exceeds £36 million), conduct supply chain audits, and monitor for modern slavery risks.
Suppliers must also comply with pre-qualification standards and SNG’s onboarding process. SNG expects a zero-tolerance approach to modern slavery and collaboration in developing solutions.
For more information, please refer to the SNG Modern Slavery Statement.
SNG maintains a zero-tolerance approach to fraud, bribery, and corruption, complying with the UK Bribery Act 2010.
Suppliers must implement measures to prevent these activities, ensure compliance, and promptly report any incidents. Inducements are prohibited, gifts and hospitality must comply with SNG’s policy, and all dealings must be transparent.
SNG will actively monitor compliance, and non-compliance may lead to contract termination.
For further details, suppliers should review the full Anti-Fraud, Bribery and Corruption Policy.
SNG is committed to safeguarding personal data in compliance with UK GDPR and the Data Protection Act 2018.
Suppliers must handle personal data responsibly, implement security measures, and report data breaches within 72 hours.
Key data protection principles include lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity, and confidentiality.
Suppliers must establish a lawful basis for processing data (e.g., consent, contract, legal obligation, legitimate interests).
They must implement data security measures, manage data breaches, and facilitate individuals' rights (access, rectification, erasure, etc.).
Data protection should be integrated into new processes, including DPIAs. Suppliers should be familiar with SNG’s Privacy notice.
It would be preferrable if contractors have been accredited by SSIP as this reduces the time required from all parties internally in checking questionnaires and clarifications, as the question set we use is very similar to SSIP
