Current PPIRs

Non-Systems Integration Testing (SIT) Supplier & Agent Post-Qualification Testing (QT) Sandbox

You should be aware of this request if you are a Non-SIT Supplier & Agent.

Elexon's Non-SIT Qualification Testing team have issued a Post-Qualification Testing (QT) Sandbox Programme Participant Information Request (PPIR) for all Non-SIT Suppliers and Agents to complete. 

The purpose of this PPIR is to support the Non-SIT Qualification Testing team to assess the scope and design of the Non-SIT Supplier and Agent Sandbox Testing tools.

The Non-SIT Supplier and Agent Sandbox is available for participants to conduct any testing beyond the minimum test set required for Qualification, in a defined period post Non-SIT QT completion, through to the current planned end date of 28 August 2026. Responses to this PPIR will be used to ensure that the Non-SIT Supplier and Agent Sandbox has the appropriate capability and scale to support necessary additional participant testing.

Please note that participant responses should reflect their Placing Reliance arrangements.

You can access the PPIR via the link below:

Non-SIT Supplier and Agent Post-QT Sandbox PPIR Form

Responses are due by 17:00 on Friday 14 November 2025.

Once this PPIR closes, the Elexon Non-SIT Qualification Testing team will collate and review the responses, assess them against their testing resource plans, and present an update on the proposed approach at the Qualification Test Execution Forum (QTEF) and Qualification and End-to-End (E2E) Sandbox Working Group (QWG).
