About ISG
ISG operates with integrity across every activity — meeting all legal, regulatory and ethical obligations in every country in which we operate and holding ourselves and our supply chain to the highest standards of conduct.
Our Standards
Compliance is not an afterthought at ISG — it is embedded in how we do business. Across all nine companies in the group, we maintain structured programmes covering export control, anti-bribery, modern slavery, data protection, health and safety and supply chain conduct. Our compliance culture is built on clear policies, regular training and a commitment to acting with integrity in every transaction and relationship.
We maintain a structured export control compliance programme covering our full product range. All products subject to ITAR or EAR controls are identified and classified and orders are screened against applicable control lists before shipment.
ISG operates a zero-tolerance policy on bribery and corruption in all its forms, consistent with the requirements of the UK Bribery Act 2010 and equivalent legislation in the jurisdictions in which we operate.
As part of the Diploma PLC group, ISG publishes an annual Modern Slavery and Human Trafficking transparency statement as required by the Modern Slavery Act 2015. We are committed to ensuring that slavery and human trafficking have no place in our business or supply chain.
ISG processes personal data in accordance with the UK GDPR and the Data Protection Act 2018. We have established clear policies and procedures covering data collection, storage, retention and the rights of data subjects.
The health, safety and wellbeing of our employees and visitors is a priority across all ISG companies. We comply with the Health & Safety at Work Act 1974 and associated regulations and align our management approach with the ISO 45001 standard.
ISG places clear expectations on all suppliers through our Supplier Code of Conduct. This document sets out the minimum standards we require across ethics, labour practices, environmental responsibility and quality management.
"ISG is committed to operating to the highest ethical standards in everything we do. This means complying with all applicable laws and regulations in every country in which we operate, treating our people, customers, suppliers and business partners with fairness and respect and maintaining a culture in which compliance is seen not as a burden but as fundamental to our reputation and long-term success."
Common Questions
How do you handle export control for defence products?
We maintain an export control classification programme covering our product range. Products subject to export controls are identified and orders are screened against applicable control lists. Where export licences are required, we work with customers to confirm the correct authorisations are in place before shipment. Our teams receive regular training on export control requirements and any changes to the regulatory landscape.
Is ISG registered under the Modern Slavery Act?
Yes. As part of the Diploma PLC group, ISG publishes an annual Modern Slavery and Human Trafficking transparency statement as required by the Modern Slavery Act 2015. This statement sets out the steps taken to identify and prevent slavery and human trafficking in our business and supply chain. Our statement is reviewed and approved by the board of Diploma PLC each year and is available on request.
How do you protect customer data?
We process customer data in accordance with the UK GDPR and the Data Protection Act 2018. Our full privacy policy is available on this website and sets out how we collect, use and protect personal data. We document the lawful basis for every processing activity and maintain records in line with our obligations as a data controller. Customers may exercise their data subject rights — including access, rectification and erasure — by contacting our data protection team.
What is your whistleblowing policy?
ISG maintains a confidential whistleblowing channel through which employees, suppliers and third parties can report concerns about ethical or legal misconduct. All reports are investigated independently and reporters are protected from retaliation in accordance with applicable whistleblower protection legislation. The channel is managed at group level to maintain objectivity and independence.
