Service Management
MHHS Service Management Strategy
The MHHS Service Management Strategy document defines the strategy which will underpin the management of the new MHHS services.
With the launch of key new central systems at Milestone 10 (M10) and generally much greater interconnectivity across the industry as a result of moving to the MHHS Target Operating Model (TOM), there is a requirement to introduce new service management capability to the industry to manage the delivery of the services provided by these new systems.
Within this document, only the MHHS Service Management strategy is considered. The strategy is intended to be high-level and provides a starting point and a framework for subsequent delivery phases to be delivered by Elexon, namely the Service Design, to design the requisite lower-level detail.
On Tuesday 27 February 2024, the Migration and Cutover Advisory Group (MCAG) approved v1.0 of the MHHS Service Management Strategy which you can view below:

Elexon – MHHS Service Definition Document and Low-Level Service Definition Document
Following approval of the MHHS Service Management Strategy, which the Programme developed to provide a framework for Elexon to define the subsequent Service Design delivery phases, on Wednesday 4 September 2024 Elexon published the Service Definition Document (SDD) and the Low-Level Service Definition Document (LLSD) relating to Target Operating Model Service Users for industry consultation.
The SDD defines the key support processes relating to the delivery of MHHS at a high-level. The document serves as a reference point for both Service Users and Service Partners, providing a high-level view of how Elexon will support new services.
Elexon Service Definition Document (SDD)
The LLSD defines the key support processes and integration with Elexon’s Service Portal relating to the delivery of MHHS. It covers the required service management processes and procedures used by Elexon Service Providers and Service Users based on current ITIL v4 best practice.
Elexon Low-Level Service Definition Document (LLSD)
The consultation window closed on Thursday 19 September 2024. Thank you to all participants who provided feedback. Elexon has uplifted the SDD (v2.4) and LLSD (v1.1) based on comments received from participants. You can view these updated artefacts above, along with the Consolidated Comments Log from the consultation below:
