    Data Permissions Matrix (DPM)

    The UK Link DPM is the register of data items held in our Central Data Service Provider (CDSP) systems that each user type is entitled to access.

    The supporting DPM Conditionality Document provides a summary of the DPM user types, and details any specific conditionality agreed by the DSC Contract Management Committee (CoMC) when allowing user types access to data.

    Our new online functionality makes it easier to quickly find and export DPM data.

    Enter keyword searches and apply filters for categories like user type, area, permission, view type, and version.

    The new page is being trialled in 'Beta' phase and we’d love to get your feedback to help us make further improvements.

    Priority 1 (critical files) within UK Link

    This document shows a list of file types that have been classified as Priority 1 (P1) files. These are files that are subject to a service level agreement, or form part of a timebound process, where a delay in the processing of the file could cause process failures.

    During planned outages, or when a system failure occurs, we consider these files when planning catch-up activities and when we make priority calls to process any backlogs.
