What this inquiry is asking

This inquiry examines whether England's privatised water sector is fit for purpose and identifies what systemic reforms are needed. It began as a broad review of sector governance, culture, financial management, and regulation but has intensified into an investigation of acute service failures—particularly South East Water's repeated water outages affecting 300,000+ people since 2020—to establish whether individual companies and the regulator (Ofwat) have failed to protect the public interest.

Status / emerging findings

  • The water sector has 'completely lost sight of its purpose' and operates as a network of financial services businesses rather than public infrastructure custodians—the June 2025 report found systemic failures across ten largest water companies in culture, investment priorities, and environmental accountability.
  • South East Water leadership has failed comprehensively: CEO David Hinton and Chair Chris Train both resigned by May 2026 following the committee's April 2026 evidence session, which exposed evasion on accountability, inadequate compensation (£600k vs £1.2m+ documented losses), and fundamental disagreements with regulators on root causes.
  • Regulatory framework is broken: Ofwat has failed to enforce investment standards or penalise underperformance adequately; the government committed (September 2025) to creating a single integrated regulator combining Ofwat, Environment Agency, and Natural England, with a Water Bill planned for 2026.
  • Thames Water's financial crisis (88% gearing) and operational failures (non-functional £250m desalination plant, 34% increase in pollution incidents) demonstrate that debt-laden ownership structures and deferred infrastructure investment are systemic across the sector.
  • Dividend payments and executive bonuses are misaligned with performance: water company leaders received six-figure bonuses despite major failures; the committee found evidence of circumventing bonus ban restrictions and excessive remuneration at failing enterprises.

Why it matters

Water is a critical public monopoly; 300,000+ people experienced extended service failures, and the committee found a structural mismatch between privatised profit-seeking and infrastructure accountability that threatens public health, business continuity, and environmental protection across England and Wales.

Tone arc

Inquiry shifted from procedural scrutiny (June 2025) of ownership models and regulatory structures into forensic adversarial investigation after South East Water's Tunbridge Wells outage (Dec 2025). By January–April 2026, the committee became markedly combative, with the Chair warning Thames Water of potential contempt of Parliament charges and CEOs refusing to acknowledge failures. The May 2026 report on South East Water culminated in implicit calls for leadership accountability that preceded voluntary resignations.
