Non-SIT Supplier & Agent Test Data

Non-SIT Supplier & Agent Test Data Approach and Plan

The Non-Systems Integration Testing (SIT) Supplier & Agent Qualification Testing (QT) Test Data Approach and Plan was most recently approved and baselined following industry consultation in April 2025 and by the Qualification Advisory Group (QAG) on Thursday 22 May 2025.

This document sets out the Test Data approach and provides a detailed view of specific data requirements for Non-SIT Supplier and Agent Qualification Testing.

As part of the most recent consultation in April 2025, the Code Bodies provided example Qualification Testing Framework (QTF) files to allow Non-SIT Suppliers and Agents to prepare for Qualification and data loading activities. You can view these files in the library below. Whilst these files were not issued for formal consultation, Code Bodies would be keen to receive feedback on these files as soon as possible.

Please email your feedback to the Code Bodies at [email protected] 

The contents of the QTF files are set out below, with further description and information around expected usage set out within the Test Data Approach and Plan, which you can view below, along with the Consolidated Comments Plan from the recent consultation:

Non-SIT Supplier & Agent Qualification Testing Test Data Approach & Plan v2.0 - Clean

Non-SIT Supplier and Agent Qualification Testing Test Data Approach & Plan Consolidated Comments Log

• D0269_QTF_v350.dat contains QTF Market Domain Data (MDD), e.g. Market Participant Identifiers (MPIDs) of the legacy test stubs contained within the QTF, Line Loss Factors (LLFs) etc.  
• D0270_QTF_v350.dat contains QTF MDD, e.g. MPIDs of the legacy test stubs contained within the QTF, LLFs etc.  
• MPID-SUP-mpan-legacy-YYYYMMDD.csv is a sample file, containing Test Meter Point Administration Numbers (MPANs) the Supplier should load as legacy (existing) MPANs before migrating these MPANs to MHHS at the start of Qualification Testing.
• MPID-SUP-mpan-gain-YYYYMMDD.csv is a sample file, containing details of Test MPANs to be created / won during Qualification Testing (e.g. MPAN Attributes for an MPAN that is to be gained through a Change of Supply Qualification Test Case (QTC), or a newly created MPAN in the case of a New Connection QTC).
• QTF Default Configuration Data.xlsx contains default data values required for QTCs where that data is not explicitly described in the QTF (e.g. the MPIDs of the MHHS Agents to be appointed during the migration process).
• QT-062 Consumption Data.xlsx is a sample file, containing consumption and / or meter readings to be submitted during settlement or consumption-related QTCs to enable the QTF to verify the expected results (e.g. the contents of IF-021s submitted by the Data Service). 
• LoadShape.xlsx contains lookup load shape consumption and total values. Ensure this file is open when using any QT-nnn Consumption Data.xlsx files to enable calculations to perform correctly.
