The long-awaited Water White Paper landed with a splash earlier this week.
This next stage of water sector reform promises to be a “once in a generation” overhaul of how water is supplied and regulated in England and Wales.
Does it deliver on that promise?
The context
The white paper responds to the recommendations made in July 2025 by the Independent Water Commission, which called for a “fundamental reset” of the sector.
The commission offered a blueprint for reform to reflect the scale of the challenge: ageing infrastructure, decades of underinvestment, fragmented regulation, climate change, and a growing population.
The government immediately accepted the recommendation to abolish Ofwat and establish a new, more powerful regulator.
The white paper now addresses the commission’s 88 recommendations in full.
Clearer strategic direction
The commission identified the lack of strategic direction as a root cause of underperformance.
It recommended a National Water Strategy for England and Wales, covering at least 25 years. It also suggested keeping the current price review process, which determines how much water companies can spend and charge their customers over five-year periods.
Restricting planning to five-year cycles creates uncertainty and limits investment. This process would support 5-, 10-, and 25-year investment plans.
The government accepted the latter recommendation but stopped short of committing to a full national water strategy.
It will expand the price review system to capture the 25-year planning horizon, with five-year periods offering greater detail. The price reviews will now act as a “check in” with funding attached.
The government will also expand the current approach to strategic policy statements, which guide how Ofwat makes decisions, to account for the new planning timelines. A more measurable and specific direction will offer more certainty for the sector and investors.
Merging water planning frameworks into two core tools – one for the environment and one for supply – will improve cross-sector planning and reduce the administrative burden for water companies.
Infrastructure asset health
The water system is deteriorating. Leakage remains high, sewer overflows are frequent, and many assets within the system are vulnerable to climate extremes.
Concerningly, neither the industry nor the regulator currently understands the standard to aim for or the investment needed to get there. This is because assets haven’t been fully mapped, nor is there any duty to do so.
The white paper strongly emphasises resilience and maintenance and takes important steps to improve the health of water infrastructure:
- A chief engineer will sit inside the new water regulator. Their job will be to bring back hands-on checks of water infrastructure.
- The regulator will introduce a new inspection approach for water companies, requiring health checks on pipes, pumps, and other assets. Self-monitoring will come to an end.
- Resilience standards for water assets are in development.
- The price control process will reflect a focus on maintenance and resilience. Ringfenced budgets will ensure there's enough funding for maintenance and renewal alongside building new assets.
- Dedicated teams will supervise each water company, replacing the current one-size-fits-all approach. This will help the new regulator understand how individual companies operate – and intervene before problems take hold.
The ICE and the National Engineering Policy Centre have highlighted the need for a better understanding of asset health, long-term management, and proactive rather than reactive maintenance. The white paper reflects these priorities well.
Regional system planning
The commission identified critical weaknesses in the current planning model.
Water system planning is siloed: removed from land-use, nature, transport, and other considerations. This has led to duplicated efforts, inefficiencies, and missed opportunities to deliver what society expects and needs.
To address this, the report proposed creating nine regional water authorities: eight in England and one in Wales.
The white paper pledges to improve joined-up regional planning, but stops short of creating the new water authorities.
Instead:
- Regional plans will set out investment priorities to meet national objectives.
- The government is considering opportunities to align existing planning tools and groups such as catchment partnerships. These groups will work with the Department for Environment, Food and Rural Affairs (Defra) to co-design a new regional planning framework for implementation in 2027.
- Funding for catchment partnerships will also double.
The government also recognises the importance of integrating planning with other sectors.
The reforms will bring together councils, water companies, farmers, and developers to tackle river pollution – recognising that prevention is often better than a cure.
Regulation and nature-based solutions
Current regulation is fragmented, overlapping, and ill-equipped to meet the demands of a modern water system.
A shift in culture is also needed, from transactional oversight of day-to-day operations to a supervisory, outcomes-based approach.
The white paper recognises this.
The government will create a single regulator for England, merging Ofwat, the Drinking Water Inspectorate, and relevant functions from the Environment Agency and Natural England. In Wales, economic regulation will be devolved.
In shifting towards an outcomes-based approach, some of the regulatory barriers to nature-based solutions (NBS) may be removed. However, the commission argued for updated legislation to provide a clearer framework for approving NBS.
To reduce pressure on existing wastewater infrastructure, it also called for mandatory sustainable drainage solutions (SuDS) for new developments in England – something the ICE has pushed for.
The white paper hasn’t picked up these recommendations.
Improving supply chain capacity and capability
The government acknowledges the scale of investment required: £104 billion in the current five-year asset management period alone.
But it warned that without reform, some of this investment risks being wasted.
An assessment will map the sector’s delivery needs against current and future supply chain capacity.
The use of standardised designs and practices will also be expanded.
Demand management
Improving water provision isn’t just about building and maintaining assets. Consumers also have a role to play in managing demand.
The white paper confirms the roll-out of smart metering and mandatory efficiency labels on items like dishwashers and washing machines.
This will help households monitor their water use and cut costs, delivering savings of over £125 million on water and energy bills over the next decade.
Public trust
The UK has one of the highest-quality drinking water supplies in the world, but challenges in tackling wastewater over recent years have left the public with low confidence.
The ICE’s polling last year found that 62% of the British public feels poorly informed about major infrastructure projects.
Transparent communication about where investment is going, and what it will deliver, is essential to rebuild trust.
Defra recognises the need for public engagement and its own role in helping people understand the long-standing challenges and trade-offs to be managed in the system.
A group of new and strengthened bodies will also support greater accountability and transparency in the water system.
An independent ombudsman (who investigates and resolves complaints) will strengthen protection for consumers, and a powerful new consumer council will build on the existing model.
The new regulator will also work with a drinking water quality advisory group.
The ICE’s view
The water and wastewater system isn’t just about pipes and pumps. It’s about public trust, environmental stewardship, and long-term resilience.
The ICE welcomes the government’s Water White Paper as a response to the Independent Water Commission’s comprehensive and unflinching report.
Managing complex systems like water networks requires improved regulation, long-term planning, and significant investment.
While the white paper doesn’t commit to every recommendation in the commission’s report, it’s worth acknowledging how big a shift this will be for the sector.
A new regulator, improved long-term planning, and a laser focus on maintenance and resilience are all issues that have long needed addressing.
The commitment to employing a new chief engineer – putting engineering knowledge at the heart of water regulation – is also an important step forward for our industry.
We now await a transition plan, interim strategic policy, and ministerial direction that will provide more certainty for water companies and consumers while the new regulator is set up.
A water reform bill will then follow to bring these changes into law.
Delivering this magnitude of change is going to be a big job. The ICE is ready to support efforts that turn these commitments into meaningful change.
