Qualification Assessment Document
All Systems Integration Testing (SIT) and Non-SIT participants that are planning to Qualify in the MHHS arrangements should review and provide comments on this document.
The Qualification Assessment Document (QAD) sets out the information and evidence that all Suppliers, Supplier Agents, Meter Equipment Managers (MEMs), and Licensed Distribution System Operators (LDSOs) are required to provide to the Balancing & Settlement Code (BSC) and Retail Energy Code (REC) Code Bodies so that they can be MHHS Qualified to operate the new arrangements.
The QAD has been developed through discussions with the MHHS Qualification Working Group (QWG).


Qualification Assessment Document (QAD)
Ofgem approved the Balancing & Settlement Code (BSC) Modification, P476 Exemption from MHHS Requirements for Smart Meter Segment (SMS) Supplier Qualification on 23 January 2025.
P476 sought to allow the BSC Performance Assurance Board (PAB) to have the authority to exempt Suppliers from Smart Segment Qualification obligations, allowing Suppliers operating in the advanced market segment that do not have the systems, processes or controls in place to meet these obligations to be exempted from Design, Test and Build.
A paper was taken to the Retail Energy Code (REC) Performance Assurance Board in February 2025 to approve the principle that a Supplier may be granted a derogation on obligations around Smart Segment Meter Points when they complete MHHS Qualification with an approved exemption.
Following Ofgem’s approval of BSC Modification P476, the Code Bodies updated Section 5.1.1 of the Qualification Assessment Document (QAD), setting out additional criteria and expectations for participants that are seeking a SMS exemption. This includes asking Suppliers to provide detail on the controls they have in place to identify, prevent the onboarding and migration, and de-register any SMS Meter Points in their QAD Submissions.
Please note that the updates only apply to participants seeking a Smart Meter Segment exemption and do not impact Systems Integration Testing (SIT) participants or Non-SIT Licensed Distribution System Operators (LDSOs).
The Code Bodies published the updated QAD for industry consultation, which closed on Wednesday 26 February 2025. Thank you to all participants who submitted comments or confirmed review of the artefacts.
The Code Bodies have reviewed and responded to all participant feedback. An update was given at the Qualification Working Group (QWG) on 11 March 2025, followed by approval of the updated document at the Qualification Advisory Group (QAG) on 20 March 2025, and the Retail Energy Code (REC) and Balancing & Settlement Code (BSC) Performance Assurance Boards (PABs) on 25 and 27 March 2025, respectively.

Completing the QAD
To support efficient review of information and evidence from parties, there are two formal QAD submission stages. The timeframes for submission are set out in Appendix C of the Qualification Approach & Plan (QA&P), which you can view on the Qualification Approach & Plan page of this website.
Please note that although we have provided a PDF version of the QAD, the format of the QAD submission will be via the QAD Portal. We have also provided a Word version so participants can prepare and draft their responses ahead of accessing the QAD Portal.
All Non-Systems Integration Testing (SIT) Suppliers & Agents will be onboarded to the QAD Portal in the two weeks before the opening of their Initial QAD submission window, which will be dictated by participants' allocated Qualification Wave.
The Code Bodies and Data Integration Platform (DIP) Manager have published Qualification Assessment Document (QAD) Guidance to support participants in preparing their QAD submissions. This document includes guidance on the content of the QAD, as well as the QAD Portal.
