Key Points

  • Haydale plc (AIM: HAYD) — advanced materials and clean-technology group
  • Mark Sait has stepped down from the Haydale Group Board, effective 9 November 2026

Mark Sait Exits Haydale Group Board to Lead SMCC's New National Delivery Model

The announcement states that Mark Sait's departure from the Haydale Group Board is driven by the need to concentrate fully on his chief executive responsibilities at SaveMoneyCutCarbon. The company cited the implementation of SMCC's new national delivery model as a key factor, with the structural details of that model having been disclosed in the 13 October 2026 FY26 Trading Update. Sait had held a dual role as both SMCC CEO and Haydale Group Chief Commercial Officer, and the board change reflects the demands of executing the revised SMCC strategy across its national sales, programme management, and installer network operations.

SaveMoneyCutCarbon's Role as Haydale's B2B Go-to-Market Platform and Impact Partner Network

SaveMoneyCutCarbon functions as Haydale's embedded B2B commercial platform, providing national coverage through sales, programme management, and an installer network. The announcement notes that through its Impact Partner Programme, SMCC originates pre-qualified demand via long-term agreements with UK banks and utilities. This positions SMCC as central to Haydale's integrated commercial model, which combines product innovation with customer access and delivery capability. The focus on executing a new delivery model for SMCC suggests the subsidiary is undergoing a meaningful operational evolution, making Sait's undivided leadership attention a priority for the Group.
