Its been a turbulent time in the UK water sector over the last few years.
An Independent Water Commission was established in October 2024 to deliver recommendations to government on reforms to the water sector. It is chaired by Former Deputy Governor of the Bank of England, Sir Jon Cunliffe.
On Monday, Sir John Cunliffe published a detailed report to attempt to address a number of the concerns experienced in the UK water sector:
- Rulebook has failed, leading to underinvestment, pollution, high consumer bills, debt and shareholder payouts
- Holistic oversight is believed necessary to coordinate planning, enforcement, infrastructure and environmental regulation in one body
- Investor appeal depends on a predictable, stable regulatory environment with clear resilience and capital rules
- Consumer trust needs rebuilding via better complaint resolution (ombudsman), billing fairness (meters + social tariffs), and environmental standards
While there were 88 recommendations, they propose:
- Merge multiple bodies into a new single regulator – For England: Combine economic, drinking-water, and environmental oversight. For Wales: Shift economic regulation to Natural Resources Wales
- Adopt a supervisory approach – Regulators to monitor firms individually, not just through benchmarking
- Set minimum capital and resilience requirements – Similar to banking, ensuring water firms hold sufficient assets to weather financial and infrastructure shocks
- Make smart meters compulsory – To reduce water use and target consumption
- Upgrade consumer protection – Create a statutory water ombudsman via the Consumer Council for Water
- Grant regulatory flexibility on fines – Introduce a “turnaround regime” allowing penalty relief in exchange for restrictions on dividends/executive remuneration
- Boost regulator’s independence and pay – Remove public-sector pay caps to attract technical and financial talent
The abolishment of Ofwat marks a critical day in economic regulation. The Independent Water Commission proposed to scrap Ofwat due to:
Fragmented regulation led to systemic failure
- Ofwat’s economic role is separate from environmental regulators (Environment Agency, Natural England, Drinking Water Inspectorate), causing disjointed oversight
- The Commission found regulators “desk‑based” and reactive rather than proactively supervising individual companies like banks
Weak supervision hurts infrastructure and environment
- Polluting companies (e.g., Thames Water) underinvested and accumulated debt partly due to light-touch economic regulation
- Resilience metrics (sewer failures, leaks) were “backward-looking” and inadequate
Investor confidence damaged by unstable regulation
- The current model penalises poor performance harshly but lacks flexibility, discouraging long-term, low-risk investment
The impacts on Ofwat will be far reaching:
Dissolution of its core functions
- Economic regulation: Folded into the new, integrated regulator in England; transferred to Natural Resources Wales in Wales
- Drinking-water oversight: Merged into the new regulator.
- Environment and resilience duties: Transferred from existing environmental agencies
Role transformation
- Shifts from benchmarking-based price reviews to supervisory, tailored oversight of each provider’s financial health, governance, and environmental practices
Staffing realignment and recruitment
- A new regulator will recruit specialists at competitive pay outside typical public-sector limits
So the key questions is, what happens next? Immediately, the Government has accepted key reforms (regulatory merger, ombudsman, smart meters, resilience standards). A new legal framework and legislation is expected by 2026, with a 2‑year transition before Ofwat is fully abolished
The Independent Water Commission sees Ofwat’s abolition as vital to building a modern, unified, expert-led regulator—but only if it’s backed by strong legislation, skilled staff, budget, and an enforced mandate. The government appears aligned and is moving forward now with high-level approval and a multi-year implementation plan. However, the execution—ensuring technical competence, clarity, and multi-sector coordination — will determine whether this reform truly overhauls the water sector.
