Summary

This report is the final recommendations of the Independent Water Commission following a comprehensive review of the water sector across England and Wales. It identifies systemic challenges and proposes a strategic, legislative, regulatory, and operational overhaul aimed at restoring public trust, enhancing environmental outcomes, and ensuring long-term resilience. The report is structured around seven reform themes and a final implementation chapter, with 88 detailed recommendations targeting government, regulators, and water companies.

Key Take Aways

  • A new long-term, cross-sectoral National Water Strategy is recommended for both England and Wales to provide strategic clarity, coherence, and direction.
  • Creation of regional water authorities to foster local engagement and accountability in water planning and investment decisions.
  • Integration of water regulators in England (Ofwat, DWI, EA, Natural England) into a single regulator; Wales to embed economic regulation within NRW or establish a new economic regulator.
  • Fundamental overhaul of economic regulation, introducing a company-specific supervisory model alongside existing benchmarking mechanisms.
  • Major revisions proposed to the Price Review process to prioritise asset maintenance and reduce investor risk.
  • Mandatory national social tariffs to support low-income households and creation of a single water ombudsman for customer redress.
  • Legislation to be updated to address public health and environmental concerns, with enhanced powers for regulators.
  • Clear statutory resilience standards for infrastructure to ensure long-term system and asset integrity.
  • Significant improvements to governance and transparency in water companies, including new senior executive accountability regimes and powers to block investor control changes.
  • Stronger incentives and frameworks for innovation, including regulatory sandboxes and new funding models.
  • Wales-specific recommendations include alignment with the Well-being of Future Generations Act, agricultural pollution management, and resilience investment planning.

Innovation

  • Introduction of regulatory sandboxes to trial innovative approaches in water management without full regulatory exposure.
  • Shift from industry-wide benchmarking to tailored company supervision to improve regulatory oversight and reflect local circumstances.
  • Recommendation to consolidate nine existing business plans into two integrated frameworks (‘Water Environment’ and ‘Water Supply’) for simplicity and coherence.
  • Proposal for a clear government-led prioritisation framework to guide regulators in navigating trade-offs between affordability, environmental goals, and investment needs.

Key Statistics

  • Over 50,000 responses received to the Call for Evidence.
  • Agriculture is responsible for 62% of phosphorus loading in Welsh SAC rivers; storm overflows account for 28%.
  • The water sector is projected to require an additional 5 billion litres/day by 2055 due to population growth and policy demands.
  • The Water Industry National Environment Programme (WINEP) budget rose from £5.7 billion to £23.9 billion (2022–2023 prices) in the 2024 Price Review.
  • In Wales, 95% of the water supply comes from surface water; only 5% from groundwater.
  • Dŵr Cymru (Welsh Water) operates under a not-for-dividend model, contrasting with private company structures in England.

Key Recommendations for Customers in Arrears and Vulnerable Customers:

1. Introduction of a Single, Mandatory Social Tariff

  • Proposes a national social tariff scheme to provide consistent, fair support for low-income households who struggle to pay their bills.
  • Aims to replace the current patchwork of company-specific schemes with a unified approach across England and Wales.

2. Creation of a Mandatory Water Ombudsman

  • Recommends upgrading the complaints framework by creating a statutory ombudsman for the water sector.
  • This would ensure clear, independent redress for customers, including those with unresolved arrears or service issues.

3. Enhanced Customer Experience Metrics

  • Recommends the introduction of a new customer experience metric for the regulator to better hold companies accountable for service to vulnerable and indebted customers.
  • Designed to incentivise improvements in treatment, complaint handling, and overall care for those most at risk.

4. Stronger Role for Citizens Advice

  • Suggests transferring the consumer advocacy role from CCW to Citizens Advice, enabling a more coordinated approach to advice and support for financially vulnerable customers.

5. Supervisory Regulatory Model

  • A new regulatory supervision model would place increased emphasis on how companies serve vulnerable and indebted customers, not just financial or environmental metrics.
  • This model would enable tailored regulatory oversight and ensure companies are proactively supporting at-risk consumers.

6. Affordability Safeguards within Price Reviews

  • The revised price review framework would require water companies to demonstrate how they are addressing affordability and reducing the burden on low-income and vulnerable customers.
  • Reinforces the principle that bill increases must be justified by clear service improvements and support mechanisms.

7. Protection During Service Disruption

  • Resilience standards and infrastructure recommendations explicitly include a focus on ensuring that vulnerable customers are not disproportionately impacted by supply interruptions, emergencies, or asset failures.
