Non-SIT Supplier & Agent QT Test Scenarios and Test Cases Combined, Partial Reliance and No Reliance Artefact

To provide QT test prioritisation guidance for participants, the Code Bodies have published:

• A combined list of all Non-SIT Supplier & Agent QT Test Scenarios and Test Cases
• A baseline list of Non-SIT Supplier & Agent QT Test Scenarios and Test Cases for participants placing partial reliance
• A baseline list of Non-SIT Supplier & Agent QT Test Scenarios and Test Cases for participants placing no reliance

These lists were updated in October 2025 to reflect the Code Bodies request for participants to execute and complete the appropriate minimum test set before any other tests are run.

At the same time, a change was made to the artefact where QT-093 in the no reliance test set was updated to include Advanced Data Service (ADS). Please note that this change is subject to the latest Balancing & Settlement Code (BSC) Assessment Criteria (version 5.1) being consulted on and approved at November's Qualification End-to-End (E2E) Sandbox Working Group (QWG), Qualification Advisory Group (QAG) and the BSC Performance Assurance Board (PAB). 

Since then, the Code Bodies identified that the minimum test set did not include any test relating to Unmetered Supplies (UMS). To ensure that all market segments are appropriately tested and evidenced in QT, the Code Bodies have identified five additional UMS-specific test cases and incorporated these into the updated minimum test set, which you can view via the links below:

This impacts all Suppliers conducting QT who haven't applied for a UMS exemption. Impacted Suppliers who have already submitted their QT Requirements to Test Traceability Matrix (RTTM) will be required to re-submit for QT Exit reflecting the additional UMS test cases. For Suppliers who have deferred their non-QT Entry Pre-Integration Testing (PIT) evidence, this can be done as part of the Final PIT RTTM submission.

Please note that Test Cases will be automatically added to the Qualification Testing Framework (QTF) for all impacted Suppliers, and that there is no requirement for Suppliers in Waves 1-3 to re-submit their Test Catalogues.

Suppliers who are currently not UMS exempt but would like to apply for an exemption should contact the Code Bodies at MHHSQualification@elexon.co.uk
