The UK Government has confirmed plans to introduce a new Clean Water Bill as part of the legislative programme outlined during the King’s Speech, signalling what ministers describe as a major overhaul of water regulation, environmental protection and infrastructure investment across the UK water sector.

Announcing the legislation during the State Opening of Parliament on 13 May 2026, King Charles III said the Government would “improve critical infrastructure with legislation to clean-up the water industry”, placing water reform alongside wider measures focused on infrastructure resilience, public service reform and national security. These proposals follow the recommendations of the Independent Water Commission, as outlined in the 2025 Cunliffe review which critiqued England’s privatised water industry, and Labour’s white paper.

A welcome shift

According to the Government’s accompanying background briefing notes, the Bill is intended to respond to growing public concern over sewage pollution, river water quality and the environmental performance of water companies.

The proposed water reforms signal a key shift in emphasis: Rather than focusing solely on water companies, the legislation aims to address pollution more broadly, including contributions from agriculture and industry. This wider lens has long been considered missing from water policy.

The Bill also promises a more unified regulatory system. The financial regulator Ofwat, the Drinking Water Inspectorate and the water-related arms of the Environment Agency and Natural England would be brought together under a single regulatory umbrella. The government says the intention is to end the fragmented oversight and create a more powerful single regulator with expanded responsibilities covering pollution control, environmental performance and drinking water protection.

This Bill will:

• Create a new Water Ombudsman to give households and communities more recourse when water companies fall short.
• Restructure water regulators into one ‘super regulator’ with a wider remit covering both the economic and environmental performance of water companies.
• Provide the mandate for companies to secure longer term, more sustainable finance for investments.
• Make housing development and sewage work better together to provide for new homes.

While these headline ambitions are likely to be broadly welcomed by the sector, the question of whether they go far enough, and within what economic model, is already drawing scrutiny.

Radical reform or reboot of privatisation?

Public opinion polling consistently shows strong support for bringing water back into public ownership. Labour’s white paper, however, places clear emphasis on “making water a more attractive and reliable sector for investors seeking stable and fair returns”. This focus will likely aggravate concerns among campaigners, as it suggests continuity with an economic model widely blamed for underinvestment, rising bills and environmental harm.

Climate change and long-term planning seemingly absent

Despite the government promising more joined‑up and longer‑term regional planning for water, climate change is reportedly only mentioned once in the government’s 53‑page white paper, in a brief statement about “future‑proofing” the regulatory framework against emerging pressures. This is a notable omission given that Ofwat reports from more than 20 years ago were already warning that climate change would require long‑term planning and major infrastructure investment.

The gap is particularly concerning in practise. Changing rainfall patterns are already increasing sewage discharges and straining ageing infrastructure. Periods of low river flow and drought are making pollution events more damaging, as contaminants become more concentrated in a smaller volume of water. Projected water scarcity will further intensify competition between households, agriculture and industry, making clean water an ever more valuable resource.

Key updates to watch for

Further details on the scope of the Clean Water Bill and its implementation timetable are expected when the legislation is formally introduced to Parliament later this year. The Clean Water Now coalition, a group of over 40 environmental organisations, has set out three central asks for the Bill: to fix the system, stop the polluters, and restore nature. How comprehensively the legislation addresses each of those asks will be the measure by which the sector judges whether this is genuine transformation or a more modest reset.
