Qualification Approach and Plan

The Qualification Approach and Plan (QA&P) applies to all participants that are required to complete MHHS Qualification, whether they plan to undertake testing through the Systems Integration Testing (SIT) or Qualification Testing (QT) route.

The QA&P sets out the purpose of MHHS Qualification during the MHHS Programme and the high-level plan and requirements for Programme participants to undertake in relation to the Balancing & Settlement Code (BSC) and Retail Energy Code (REC).

The QA&P is supported by four Annexes:

1. Annex 1: Non-SIT Licensed Distribution System Operator (LDSO) MHHS Qualification Testing Approach   
2. Annex 2: Non-SIT Supplier & Agent MHHS Qualification Testing Approach
3. Annex 3: New Entrant Non-SIT LDSO MHHS Qualification Testing Approach 
4. Annex 4: Non-Completion of Qualification 

Qualification Approach & Plan and Annex 2 Consultation

On Monday 19 May 2025 the Programme and Code Bodies published the QA&P and Annex 2 for industry consultation. 

The QA&P was updated to reflect the change in Programme terminology from Systems Integration Testing (SIT) Minimum Viable Cohort (MVC)/Non-MVC to M10 Ready/M11 Ready/Not M11 Ready as well as reflecting the approval of the Smart Exemption and updates to the Legacy Arrangement assurance.

Annex 2 was updated to reflect the removal of the Central Switching Service (CSS) simulator from the Qualification Testing Framework. 

The consultation closed on Friday 30 May 2025. Thank you to all participants who provided a response. 

Participant feedback and comments have been triaged by the Code Bodies and the artefacts have been updated to reflect these, as captured in the Consolidated Comments Log which you can view below:

If you have any questions on the QA&P or any of the Annexes, please email the Code Bodies at MHHSQualification@elexon.co.uk 

Participant Qualification Journeys 

The Code Bodies have created a series of Plans on a page (Poaps) showing the Qualification Journey for Non-Systems Integration Testing (SIT) Supplier & Agent Wave 1, 2, 3 and 4 participants, running from the Pre-Integration Testing (PIT) Requirements to Test Traceability Matrix (RTTM) submission through to Service Activation. You can view these below:

Please note that: 

• The Poaps are aligned to the QA&P v4.0 Annex C and MHHS Programme Plan v6.18. 
• The QA&P v4.0 Annex C and MHHS Programme Plan depict the Qualification Waves as a series of ‘windows’ of activity, within which each participants activity should be completed. 
• Participants are not required to adhere to the Qualification dates set out in the MHHS Programme Plan precisely and could for example complete their activities earlier. However, the expectation is that a participant completes all activities they are responsible for within the required window. 
• At the December Qualification Working Group (QWG), the Programme presented the go early / late pathways using Qualification Wave 2 as an example to bring this to life for participants.
• You can view the December QWG papers on the QWG page of the Collaboration Base.
• As part of the Service Activation process, participant’s Migration Plans will need to be agreed with the Programme.
• When further information on the timeframes for these activities have been agreed, the Code Bodies will update the Qualification Journey Poaps to reflect this.
