Qualification Requirements to Test Traceability Matrix (RTTM)
Code Bodies have provided RTTM templates for each non-SIT Party type to support the assessment of testing activity.
They clarify minimum requirements for test execution in Pre-Integration Testing (PIT) and will set out what is expected for Qualification Testing as well as any evidence that must be provided e.g. to support the Qualification Assessment Document (QAD) submission.
Parties are required to complete the template to show that all tests have been executed and provide evidence of this.
To view the RTTM templates, please visit the Qualification Requirements to Test Traceability Matrix (RTTM) page of this website.
Placing Reliance, Qualification Testing (QT) and Pre-Integration Testing (PIT)
Non-SIT Suppliers, Agents, Meter Equipment Managers (MEMs) and New Entrant Licensed Distribution System Operators (LDSO)s are required to provide a Pre-Qualification Submission (PQS).
The PQS collects information from each Programme participant on its preferred Qualification Wave, PIT approach and completion timescales, target migration date, and Placing Reliance information. The PQS provides Code Bodies with the information required to make an informed judgement on a participant’s plans and readiness for its preferred Qualification Wave, confirms the Placing Reliance approach and what tests the participant will be required to undertake in Qualification Testing (QT). For the avoidance of doubt, a Programme participant cannot be allocated to a Qualification Wave before any participant that it is Placing Reliance on.
Code Bodies seek to flex testing and assurance capacity to meet Programme participant Qualification Wave requests as far as possible but may, as a last resort only, need to implement a reallocation process if all participants’ requests cannot be met. The reallocation process will not be a first come, first served approach, and we’ll engage participants before this process.
Once allocated, Code Bodies will use several checkpoints to monitor progress against the QT Entry Criteria (see the Qualification Approach & Plan (QA&P) Section 10.6 for further information on QT Entry Criteria). Where a participant is not deemed to be on track for QT Entry they may be moved to a later wave. A wait list process will be in place where participants are looking to move into an earlier oversubscribed wave.
Each participant is required to complete PIT (assured by the Elexon Qualification Test Manager, using defined PIT Exit Criteria), provide its QT Test Plan and undertake its other MHHS Qualification preparation activities, such as Data Integration Platform (DIP) onboarding, in accordance with the plans provided in its Pre-Qualification Submission. The participant will then be required to submit its initial Qualification Assessment Document (QAD). Code Bodies will review the initial QAD submission, seeking clarifications where required, and confirm that the participant can start QT in its allocated Qualification Wave.
Elexon’s Qualification Test Manager will manage QT. A more detailed explanation of the QT process is set out in Annex 2: Non-SIT Supplier and Agent MHHS Qualification Testing Approach and Plan and will be set out in Annex 3: New Entrant Non-SIT LDSO MHHS Qualification Approach.
More information on the Qualification Approach & Plan including the documents are available on the Qualification Approach & Plan page of this website.
A Programme participant should continue to develop its final QAD submission in parallel with QT.
Where a test cannot be completed in QT, we expect Non-SIT participants to develop work-off plans which are reviewed with the Elexon Qualification Test Manager and agreed with the Code Bodies.


Completion of Qualification Testing
Once a participant has completed QT (assured by the Elexon Qualification Test Manager, using defined QT Exit Criteria), they must submit a final QAD. Code Bodies will review the final QAD submission and work with the participant to finalise it. Once the content has been agreed as complete for the purposes of MHHS Qualification, it must be signed by a Company Director (or delegate for roles governed only under the Retail Energy Code (REC).
Code Bodies will then approve MHHS Qualification for the Supplier, Agent or new entrant LDSO in accordance with the QA&P Section 11.3 MHHS Qualification Approval. Once MHHS Qualified, the participant must complete Service Activation before it can operate the new MHHS arrangements. Service Activation, as described in the QA&P Section 7.3.3 Service Activation, is out of scope of the QA&P and will be managed by the MHHS Programme.
A summary of the MHHS Qualification steps for Non-SIT Suppliers, Agents, MEMs and New Entrant LDSO participants is set out in the image below.
Steps for MHHS Qualification
SIT QT Work Off Plan Template
The SIT and QT Testing Work Off Plan template has been published. You can view the document below:
SIT Qualification Testing Work-Off Plan Template
The purpose of template is to capture any work-off items where QT requirements cannot successfully be demonstrated through QT. A completed template should provide sufficient information to Code Bodies and DIP Manager so they are able to assess the impact of proposed items. Work-off items should be in line with the QT exit criteria set out in the Qualification Approach and Plan plus associated Annexes as well as Code Bodies' and DIP Manager’s Assessment Criteria, Qualification Approach & Plan and Risk Register. The completed template should be submitted alongside a Programme participant's QT completion report. Please note, providing early sight of work-off items is highly encouraged. Please note that a SIT and QT Test Plan adds risk to your Qualification being approved by Code Bodies and DIP Manager in your planned timeframes, it is therefore strongly recommended that these items are resolved during testing rather than as a work-off item.


Non-SIT Supplier and Agent Qualification Testing Onboarding Guide
The Non-SIT Supplier and Agent Qualification Testing Onboarding Guide outlines in detail the activities required to onboard to the systems required for Qualification Testing. This guide can be found below:
Non-SIT Supplier and Agent Qualification Testing Onboarding Guide
Ahead of each Qualification Wave, participants are required to onboard to multiple systems with the Qualification Environment; there are DIP, Qualification Test Framework (QTF), Azure Dev Ops (ADO). The Guide highlights key information and activities that will aid participants in onboarding to these systems.

Non-SIT Supplier and Agent Qualification Testing (QT) Test Plan Template
The Non-SIT Supplier and Agent Qualification Testing Test Plan Template has been updated to version 1.2 to include a new section 4.2 Qualification Test Execution Plan. You can view the Clean and Redlined versions below:
Non-SIT Supplier and Agent QT Test Plan Template v1.2 (Clean Version)
Non-SIT Supplier and Agent QT Test Plan Template v1.2 (Redlined Version)
The Qualification Execution Test Execution Plan section must now be completed and submitted by all Non-SIT Supplier and Agent participants proceeding through Qualification Testing. Importantly, this will be monitored and reported by the Non-SIT Supplier and Agent Team during Qualification Testing as per Ofgem requirements. This new section will also be discussed further at the June Non-SIT Supplier and Agent Qualification Testing Subgroup (SAQTSG) call.
