The Water (Special Measures) Act 2025 amends the Water Industry Act 1991 and related statutes to give regulators new, direct powers over water and sewerage companies’ governance, remuneration and public reporting, and to strengthen enforcement and insolvency-related tools. Key measures include a regulator power to ban performance‑related pay where companies fail specified standards (including consumer, environmental and financial resilience standards); a requirement that each water company publish an annual, regulator‑specified financial overview on its website; annual pollution incident reduction plans signed off by the chief executive; and a duty to publish near‑real‑time notices of discharges from emergency overflows.
The Act also tightens sanctions: it raises potential sentences for impeding environmental investigators, allows variable civil penalties to be imposed on a balance‑of‑probabilities standard for certain water offences, and requires automatic fixed penalties in most cases unless exceptional circumstances apply. It creates mechanisms for the Secretary of State and Welsh Ministers to modify company appointment conditions to recover losses from special administration orders, and updates charging, abstraction and regulatory functions to reflect climate and environmental targets.
For compliance officers and corporate boards, the Act creates new operational, reporting and reputational obligations and gives environmental regulators clearer, faster paths to financial and governance consequences.
At a Glance
What It Does
The Act authorises Ofwat (the Authority) to issue binding rules limiting performance‑related pay and imposing fitness‑and‑propriety standards for senior roles, requires annual public financial overviews, mandates pollution incident reduction plans with CEO approval, and obliges sewerage undertakers to publish emergency overflow discharge notices within one hour. It also tightens criminal and civil enforcement tools, including higher penalties for obstructing inspectors and a lower civil standard of proof for specified environmental offences by water companies.
Who It Affects
All 'relevant undertakers' (water and sewerage undertakers and, where relevant, licensed water/sanitation operators) operating in England and Wales; Ofwat, the Environment Agency and Natural Resources Body for Wales (NRBW); the Drinking Water Inspectorate; and ultimately customers, investors and creditors of water companies. The Secretary of State and Welsh Ministers gain powers to alter appointment conditions to recover special administration losses.
Why It Matters
The Act shifts regulatory focus from price controls alone toward governance, transparency and direct operational accountability—linking executive pay to environmental and consumer performance and forcing near‑real‑time disclosure of sewerage discharges. It narrows procedural barriers for enforcement and makes remedial cost recovery from the sector more direct, increasing regulatory leverage and potential cost pass‑through to customers.

What This Bill Actually Does
The Act inserts a new rule‑making power into the Water Industry Act 1991 that lets the regulator prescribe governance and remuneration arrangements for water companies. Those rules must, among other things, allow the regulator to prohibit performance‑related pay where an undertaker fails specified standards, set fitness‑and‑propriety criteria for senior appointments and require consumer representation in material decision‑making bodies.
The regulator can direct companies and enforce compliance; rules may reach back to pre‑existing contracts, allow recovery of payments made in breach, and apply differently across companies.
Separately, the Act compels each relevant undertaker to publish a concise, regulator‑defined financial overview at least annually—covering the composition of capital and debt and significant changes announced within the prior or next 12 months. The aim is to give the public and stakeholders a clear, comparable snapshot of each company’s funding and financial risks, with Ofwat deciding content and format and using appointment powers or rules to secure publication.On operational accountability, the Act requires annual pollution incident reduction plans (and annual implementation reports) that must include the frequency, causes and planned measures for incidents attributable to a company’s systems; the chief executive must personally approve the plan.
Failure to publish a plan or report is a criminal offence for the company and, subject to a 'reasonable steps' defence, for the chief executive. The Act also mandates near‑real‑time public reporting of discharges from designated emergency overflows — with initial and end notices to be published within an hour — while giving the Minister power to create narrow regulatory exceptions.Enforcement and insolvency tools are hardened.
The Act raises maximum custodial sentences (up to two years) for obstructing environmental investigators or drinking water inspectors in specified circumstances and creates corporate officer liability where offences arise from consent, connivance or neglect. It permits civil penalty regimes for certain water offences to be applied on the balance of probabilities (instead of beyond reasonable doubt) and requires regulators to impose fixed monetary penalties in defined cases unless exceptional circumstances apply.
Finally, it allows the Secretary of State and Welsh Ministers to modify appointment conditions in companies subject to special administration orders so companies may be required to raise and remit amounts to cover SAO losses, subject to published consultation procedures and timing rules.
The Five Things You Need to Know
Ofwat may ban performance‑related pay for senior roles if a company fails standards tied to consumer issues, the environment, financial resilience or criminal liability, and can void or recover payments made in breach.
Each water company must publish an annual, regulator‑defined financial overview on its website describing share capital, debt and significant announced changes within the prior or next 12 months.
Relevant undertakers must publish pollution incident reduction plans before 1 April each year and subsequent implementation reports; failure to publish is a criminal offence for the company and, subject to defence, the chief executive.
Sewerage undertakers must publish location and start time of emergency overflow discharges within one hour of commencement and the end time within one hour of cessation, with narrow exceptions only by ministerial regulation.
For specified abstraction, impounding and pollution offences by water companies, regulators may impose variable monetary penalties based on the balance‑of‑probabilities standard, and in many cases must impose fixed penalties unless exceptional circumstances exist.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
New rule‑making power on remuneration and governance
This provision gives the economic regulator (Ofwat) explicit rule‑making authority to dictate how companies compensate senior staff and structure governance. Rules must cover prohibiting performance‑related pay after specified failures, fitness‑and‑propriety appointment standards, and consumer involvement mechanisms. Crucially, rules may void contractual provisions, recover improper payments, apply to prior agreements and be varied urgently through a limited 'minor or urgent variation' procedure; that prospects of retrospective effect and recovery creates immediate legal and HR implications for companies and advisers.
Mandatory annual financial overviews for the public
Ofwat decides what a concise public financial overview must contain and in what format; companies must publish the overview annually and prominently on their websites. The section ties the requirement to Ofwat’s appointment powers or rule instruments, meaning non‑compliance is enforceable through existing appointment condition tools. The intent is to standardise disclosure of capital and debt mix and announced material changes, increasing market and consumer scrutiny of leverage and funding arrangements.
Pollution incident reduction plans, reporting and enforcement
Companies must prepare and publish annual plans detailing past incident frequency, causes, maintenance steps, planned measures and timelines; the first plan must be published by the first 1 April after the section comes into force. Subsequent implementation reports must explain implementation success or failures and corrective intentions. Enforcement rests with the Environment Agency or NRBW; failure to publish is a criminal offence for the company and potentially for the CEO, though the CEO has a statutory 'reasonable steps' defence. The regulator must consider plan implementation records when exercising enforcement discretion.
One‑hour public notices for emergency overflow discharges
Sewerage undertakers must publish four basic data points (notice of discharge, location, start time within one hour, and end time within one hour) in a readily understandable and accessible way. The Minister can make regulations carving out narrow exceptions (by overflow type, frequency or pollution risk) but such regulations require draft approval by Parliament or Senedd. The provision creates immediate operational requirements for monitoring, automated public notification systems and coordination with regulators on definitions of 'emergency overflow.'
Explicit role for nature‑based solutions in drainage plans
The Act inserts express reference to the use of nature‑based solutions in drainage and sewerage management plans, requiring companies to address how they will deploy natural infrastructure and technologies. This elevates consideration of green measures into statutory planning duties and links planning obligations to broader environmental targets.
Stronger criminal exposure and new civil penalty standards
The Act increases maximum custodial penalties for obstructing environmental regulators (up to two years) and extends corporate officer liability where offences result from consent, connivance or neglect. It allows certain civil penalty regimes to be applied on a balance‑of‑probabilities standard for specified Water Resources Act and related offences, and requires relevant agencies to impose fixed monetary penalties in specified cases unless they find exceptional mitigating circumstances or pursue alternative enforcement. The changes lower procedural barriers to monetary enforcement and raise corporate governance risk for senior officers.
General licence conditions, Ofwat duties and cost‑recovery charges
The Act enables the Secretary of State and Welsh Ministers to impose general conditions or rules of application on water industry licences (abstraction and impounding) and requires Ofwat to have regard to the UK net‑zero and other statutory environmental targets when performing relevant functions. It also empowers the Environment Agency and NRBW to recover costs by charging water companies for water industry enforcement work, and expands Drinking Water Inspectorate fee powers to cover discrete instances or time‑period charges—practical levers to shift enforcement costs to the sector.
Mechanisms to pass through costs and recover special administration losses
The Secretary of State may establish schemes to distribute costs among English undertakers where regulations impose new statutory requirements, and price‑control design must not block passing‑on of those costs. Separate provisions let the Secretary of State and Welsh Ministers modify appointment conditions following special administration orders so companies can be required to raise and remit amounts to cover SAO losses; those modifications carry procedural consultation and notice requirements (minimum 42‑day consultation, 56‑day effect window unless the consultation condition is satisfied). The Act also tightens notice and hearing rights on winding‑up petitions so the regulator and relevant Ministers are notified and heard.
Geography, staged commencement and transitional rules
The Act extends to England and Wales and sets out a staggered timetable for commencement, with many governance, transparency and penalty provisions coming into force on Royal Assent and several operational sections (pollution plans, emergency overflow reporting, nature‑based solutions and Ofwat's climate duties) to be commenced by the Secretary of State and Welsh Ministers by regulation. Regulations may make different provision for different areas and include transitional or saving arrangements; duties to consult can be satisfied by pre‑enactment consultations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Consumers and local communities — gain clearer information on company finances, quicker public notice of sewerage discharges, and a statutory channel for consumer involvement in material decisions, improving transparency and accountability.
- Environmental regulators (Environment Agency and NRBW) — receive stronger enforcement tools (automatic penalties, lower civil standards of proof in specified cases, cost‑recovery charging) and quicker public disclosure that aids monitoring and public pressure.
- Public health authorities and local water quality stakeholders — benefit from mandated pollution reduction planning, CEO accountability, and tighter reporting that should improve incident prevention and response planning.
- Policy makers and ministers — gain explicit powers to modify company appointment conditions and a mechanism to distribute sector remediation costs after special administration, giving government more direct fiscal control in failure scenarios.
- Investors seeking clarity on financial risk — obtain standardised public overviews of capital and debt composition, which should improve transparency for credit assessment and market discipline.
Who Bears the Cost
- Water and sewerage companies — face new compliance costs for producing annual financial overviews, pollution plans and implementation reports, implementing one‑hour overflow notification systems, and potential pay clawbacks or contract voiding under the new remuneration rules.
- Senior executives and boards — bear heightened personal and fiduciary risk (CEO criminal exposure for non‑publication subject to limited defence, fitness‑and‑propriety standards, and potential recovery of improper payments), increasing reputational and legal risk.
- Customers — may face cost pass‑through where the Secretary of State or Welsh Ministers and price‑control rules permit the passing‑on of costs to recover SAO losses or to implement new statutory requirements.
- Smaller licensees and third‑party operators — could carry disproportionate regulatory and administrative burdens if rules and charges designed for large undertakers are applied without proportionate adjustments.
- Enforcement agencies — while granted cost‑recovery powers, will incur implementation overheads and may need expanded capacity to apply new civil regimes, manage consultations and adjudicate appeals.
Key Issues
The Core Tension
The Act balances two legitimate aims—firm regulatory levers to stop environmental harm and hold executives accountable, versus the need to preserve operational resilience, investment incentives and legal certainty for companies; stronger, retrospective governance controls and cost‑recovery powers reduce regulatory lag but risk deterring capital, prompting litigation, or shifting burdens onto consumers.
The Act packs a lot of regulatory bite into relatively compact text, but that compactness raises implementation questions. The rule‑making route for pay and governance gives Ofwat broad discretion to define 'specified standards' and 'senior roles' and to apply rules retrospectively to existing contracts; that discretion will determine whether the provision functions as a blunt sanction or a tailored accountability tool.
Equally, the power to void contractual provisions and recover payments intersects with employment, contract and pensions law, creating potential litigation risks and complex negotiation dynamics for exit arrangements, deferred pay and third‑party service contracts.
Operationally, the one‑hour reporting requirement for emergency overflows will force investment in monitoring, telemetry and automated public interfaces. Defining which overflows qualify and which narrow ministerial exceptions apply will be central: overly broad application could overwhelm public portals with routine operational discharges; too narrow a scope could leave serious events unreported.
On enforcement, lowering the civil standard of proof and mandating fixed penalties will accelerate monetary sanctioning but invites legal challenge on proportionality, procedural fairness and the interaction between civil fixed penalties and parallel criminal prosecutions. Finally, the SAO‑cost recovery mechanism shifts contingent public costs back to company customers through price‑control adjustments or inter‑company schemes, creating political and regulatory trade‑offs about who ultimately bears insolvency costs.
