General Data Protection Regulation (GDPR)

This page houses all information in relation to MOSL’s compliance with General Data Protection Regulation (GDPR) and compliance of the market and its Market Operator systems. Information on this page relates to MOSL’s obligations towards personal data held in the central market systems, rather than personal data it has collected and holds as a business (such as employee data).

Summary of Arrangements

Under the GDPR, data controllers who jointly control personal data must make available to data subjects a summary of the arrangements and allocation of responsibilities between them. Therefore, MOSL has provided a Summary of Arrangements that will be updated yearly (if required).

Record of Processing Activities

The GDPR requires data controllers to maintain a formal written record of processing activities under their responsibility. MOSL’s Record of Processing Activities sets out an overview of the procedures, including the legal basis, upon which personal data is processed.

GDPR Guidance
