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 and Settlement Code (BSC) and Retail Energy Code (REC).
The QA&P is supported by four Annexes:
- Annex 1: Non-SIT Licensed Distribution System Operator (LDSO) MHHS Qualification Testing Approach
- Annex 2: Non-SIT Supplier & Agent MHHS Qualification Testing Approach
- Annex 3: New Entrant Non-SIT LDSO MHHS Qualification Testing Approach
- Annex 4: Non-Completion of Qualification
Qualification Approach & Plan and Annexes 1 & 2
The Programme and Code Bodies made further updates to the QA&P, Annex 1 and Annex 2 and published these artefacts for industry consultation.
In general, changes were made to ensure that the artefacts reflected updated delivery timelines following Ofgem's approval of CR055: Amendments to M10 and Corresponding Milestones, as well as the role of the Data Integration Platform (DIP) Manager in assuring Non-Functional Testing Requirements.
The consultation closed on Friday 20 December 2024. Thank you to everyone who submitted comments or confirmed review of the artefacts.
