Correspondence from the Trustees of the Nat West Group Pension Fund regarding failures at South East Water, dated 12 May 2026

From: Environment, Food and Rural Affairs Committee

Inquiry: Reforming the water sector

Summary

The NatWest Group Pension Fund, a 25% shareholder in South East Water, responds to the Environment, Food and Rural Affairs Committee's inquiry into failures at the company. The Fund states it has already concluded that both the chair and CEO are not tenable and supports their recent departures. It emphasises regulatory constraints on shareholder intervention and commits to ongoing engagement with the board while supporting leadership succession and sector-wide regulatory reform.

Key findings

  • NatWest Pension Fund acquired its 25% stake in SEW in 2017 and has provided approximately £88 million in additional capital investment.
  • The Fund had reached the view by April 2026 that both the chair (Chris Train) and CEO (David Hinton) were not tenable, independently of the Committee's report.
  • The Fund acknowledges regulatory restrictions on shareholder governance interference, noting that direct interference could breach 'ultimate controller undertakings' and expose both the company and shareholder to sanctions.
  • The Fund states it will continue shareholder engagement with the board on leadership succession and governance improvements, but recognises its role is limited by regulation.
  • The Fund notes SEW failed to secure regulatory approval for significant additional investment it would have supported, and calls for broader sector-wide regulatory and legislative reform.

Notable line

… the regulatory regime deliberately separates the governance and management of the company from its shareholders, with potential sanctions to both the company and the shareholders if this is breached.

We are pleased the latest regulatory price review goes some way to provide for necessary investment to upgrade SEW's infrastructure, but we note that SEW was unable to secure regulatory approval to make significant additional investment which we would have supported.
