Pre-Qualification Submission

Non-Systems Integration Testing (SIT) Suppliers, Supplier Agents and Meter Equipment Managers (MEMs), and New Entrant Licensed Distribution System Operator (LDSO) Programme participants are required to provide a Pre-Qualification Submission for MHHS Qualification. 

The submission will include all the information that Code Bodies need to make an informed judgement on a party’s readiness and suitability to be allocated to a particular Qualification Wave.

The information provided will also assist Code Bodies to understand the resource and testing capacity required to support each Qualification Wave.

You can find further information on Qualification Waves and more general MHHS Qualification information on the Qualification Approach & Plan page of this website.



How to complete your submission

The Pre-Qualification Submission template, available at the link below, requests provision of the following information from each Programme participant: 

  • Preferred Qualification Wave
  • Pre-Integration Testing (PIT) approach and completion timescales
  • Qualification Testing approach and completion timescales
  • Any Placing Reliance proposals, both to understand dependencies and the level of testing required in
  • Qualification Testing
  • Supplier Hub relationships to inform Migration planning, (optional)

Code Bodies will work collaboratively with participants to ensure that they are in a suitable Qualification Wave.  

To submit your Pre-Qualification Submission, download the Pre-Qualification Submission template below, and complete the fields.

Once ready, please email your document to the Code Bodies at [email protected]

To reduce the number of information requests simultaneously going to Programme participants, Code Bodies have included questions to cover MHHS readiness for other relevant Code areas within the Pre-Qualification Submission (Section 4.5).

Responses to these questions will feed into business as usual assurance arrangements under the Balancing & Settlement Code (BSC) and Retail Energy Code (REC) and will not form part of the Programme participants' MHHS Qualification Wave allocation assessment.   

Both the Code Bodies and the MHHS Programme will use the information provided in the Pre-Qualification Submission.

The Pre-Qualification Submission window opened on 5 February 2024 and final submissions must be provided by 26 April 2024.  

If you have any questions about the Pre-Qualification Submission, Placing Reliance, or anything further please email [email protected]

Pre-Qualification Submission Drop-in Sessions

Code Bodies are hosting drop-in sessions for participants who require further support in completing their Pre-Qualification Submission (PQS).

The sessions are open to all participants completing the PQS and they will be recorded and published on the Collaboration Base. They take place on:

  • Thursday 4 April 2024 at 11:00 – 12:00
  • Tuesday 9 April 2024: there will be a session at the end of the Qualification Working Group
  • Wednesday 17 April 2024 at 14:00 – 15:00  

To receive an invite, please email [email protected]

The PQS Webinar Q&A document, which is available further down this page, will be updated following these sessions to support participants with completing their PQS.  

The sessions will only focus on the PQS, and questions raised outside of this scope will not be answered during the session. Given that the sessions will be recorded and attended by a wide audience, we advise participants not to share confidential information during the call.

We'd also like to remind participants that you can complete the Placing Reliance section of the PQS and share it with the Code Bodies by emailing [email protected] ahead of the PQS deadline on Friday 26 April to receive feedback on your proposal.
