Qualification Background
The Qualification phase of the Programme is in place to assess whether Programme participants that plan to operate in MHHS, have the appropriate systems, processes and controls in place to undertake the Balancing & Settlement Code (BSC) and Retail Energy Code (REC) requirements for the MHHS Design.
In summary, the high-level Qualification evidence requirements include:
- PIT DBT1: Evidence PIT completion to enter Qualification Testing which will prove specific functional, non-functional and migration related characteristics of systems and processes.
- SIT/Qualification Testing: Participants are expected to complete either SIT or Qualification Testing, and document evidence in the Qualification Assessment Document (QAD).
- Placing Reliance: A policy for placing reliance was consulted on to reduce unnecessary duplication of effort for participants when completing the evidencing testing as set out in the 'Placing Reliance' policy. If this policy is applied, evidence to support it should be provided in the QAD, applying the principles set out in the policy.
- Procedural and Governance: All participants are expected to adhere to the processes and procedures of the Code Bodies to fulfil the requirements of the role; evidence for this will be documented in the QAD.
