What Water UK does
Water UK is the trade association representing all UK water and wastewater companies, operating as a company limited by guarantee since its founding in 1998. Headquartered in London with a small team of 11-50 employees, it serves as the collective voice of the UK water sector in dealings with regulators — including Ofwat, the Environment Agency, the Drinking Water Inspectorate, and the Competition and Markets Authority — as well as with government and wider stakeholders.
The organisation's core activities centre on policy advocacy, sector representation, and the delivery of cross-industry programmes. Notable initiatives include "The Big Upgrade," a £104 billion infrastructure investment programme for 2025-2030 targeting 50,000 new jobs; the Stream open data platform developed in partnership with Ofwat; the Discover Water customer information service; the ConnectRight new-connections programme; the River Deep Mountain AI waterbody monitoring system using remote sensors; and the recently appointed Dispute Resolution Ombudsman serving household customers. Water UK has also been a prominent advocate for legislation banning plastic wet wipes.
Water UK's revenue model is membership-funded: all UK water and wastewater utilities pay subscriptions to support its activities, with no external investors or commercial revenue streams. The appointment of an alternative dispute resolution ombudsman in May 2026 introduces a per-household levy component, modestly diversifying the funding base. Strategic priorities for 2025-2026 include shaping PR24 redeterminations, supporting the transition to a proposed unified water regulator, and driving sector-wide adoption of AI-enabled monitoring and leakage detection.

Water UK partnerships and signals
Strategic signalPartnerships
Five partnerships are on record, tiered core and minor.
- Dispute Resolution OmbudsmancoreAppointed by Water UK to deliver free and independent alternative dispute resolution services for water company customers in England and Wales. This service was previously provided by Consumer Council for Water until Defra instructed it to cease on 24 April 2026. The service initially applies to customers of the largest water companies serving more than 99% of connected properties, with smaller water companies joining at a later date. Water UK and members have arranged for any cases previously being handled to continue without interruption.
- ConnectRight PartnershipcoreA partnership between environmental regulators, water companies, authorities and professional organisations working to reduce water pollution from drainage misconnections. The campaign addresses the issue of misconnected property drains that pollute rivers and beaches throughout the UK, providing guidance and enforcement support.
- Ofwat (Stream Project)coreWater UK and water companies participate in the Stream open data platform, funded by regulator Ofwat. This platform facilitates sharing of water quality, consumption, and leakage data across the sector, representing a collaborative approach to transparency and data-driven improvements.
- Competition and Markets Authority (CMA)minorWater UK engaged with the CMA during the redeterminations process for PR24, submitting third-party submissions and responding to the authority's determinations. Water UK criticized Ofwat's final determinations being overturned by the CMA as evidence of regulatory system failure.
- All UK Water and Wastewater CompaniescoreWater UK is funded by and represents all water and wastewater companies across England, Scotland, Wales and Northern Ireland, including Anglian Water, Thames Water, Severn Trent, United Utilities, Southern Water, Yorkshire Water, Welsh Water, and others. The organization develops policy, shares best practices, and advocates on behalf of its members.

Water UK competitors and assessment
Company assessmentDirect peers
- Water Environment Federation (WEF): US-based not-for-profit association for water quality professionals covering wastewater and stormwater. Comparable as a trade body advancing the water sector through standards, education, and advocacy, with focus on the wastewater side.
- Water Services Association of Australia (WSAA): Australia's peak water industry body representing urban water utilities. Directly comparable as a national trade association coordinating policy, advocacy, and standards for the water sector across a single country.
- American Water Works Association (AWWA): The largest water industry association in North America, representing utilities and professionals across drinking water supply. Comparable role in standards development, advocacy, and member coordination, though larger in scope and global reach.
- EurEau: The European federation of water sector national associations, representing operators and associations across Europe. Directly comparable as the supranational layer above national water trade bodies like Water UK.
- Aqua Publica Europea: European association of public water operators, focused on public ownership and sustainable water management. Comparable as a sectoral association advocating for water utilities at EU level, with overlapping membership from public water companies.
- UK Water Industry Research (UKWIR): UK-wide research organisation jointly funded by water companies to coordinate collaborative research. Comparable as a membership-funded body serving all UK water companies, with a narrower remit focused on research rather than advocacy.
Broad incumbents
- Ofwat: The economic regulator of the water sector in England and Wales. Not a peer in the trade-association sense but a key counterparty to Water UK whose decisions shape the regulatory environment in which Water UK operates.
- Drinking Water Inspectorate (DWI): The regulator of drinking water quality in England and Wales. Adjacent to Water UK as the technical regulator whose standards Water UK's members must comply with.
Emerging players
- Consumer Council for Water (CCWater): The statutory consumer body for water customers in England and Wales, recently directed by Defra to cease dispute resolution services. Comparable as a water-sector body with a customer/consumer mandate balancing industry interests.
Others
- WaterAid: International water and sanitation NGO. Not a direct peer but an adjacent organisation operating in the UK water policy ecosystem, often partnering or competing for attention on water-sector issues.
