Request for Urgent Response to M10 Contingency Scenarios and Plans Impact Assessment

You should be aware of this request if you are a Programme participant. 

The Programme has been undertaking a contingency planning exercise to identify what action the Programme and participants may have to undertake if certain conditions are not met for M10 decision making. 

Please note that the Programme is progressing on the basis of delivering the Cutover Plan to meet M10 and that this contingency planning exercise is being carried out to ensure the Programme and participants are suitably prepared for any exceptional circumstances if they were to arise. 

To-date the Programme has engaged with M10 parties through focused bilaterals and workshops to discuss scenarios, feasible contingency plans and associated assumptions. 

The Programme Participant Information Request (PPIR) is an opportunity to formalise feedback through impact assessment and was issued to all Principal Contacts last Friday 5 September 2025.

Participant Principal Contacts have until 17:00 on Thursday 11 September 2025 to review the contingency scenarios and plans and respond to the impact assessment. 

The Programme recognises that it is a significant ask and does not allow much time for participants to complete the impact assessment, but these timelines will ensure that the Programme has appropriate feedback and insights in advance of Programme Steering Group (PSG) on Friday 12 September 2025 as set out in the M10/M11 decision-making choreography.
