Overview of the Decision
On October 9, 2025, the UK’s Competition and Markets Authority (CMA) provisionally approved additional bill increases for five major water companies: Anglian Water, Northumbrian Water, South East Water, Southern Water, and Wessex Water. This decision allows these firms to raise charges by an average of 3% over the next five years, adding to a previously approved 24% increase by the industry regulator, Ofwat. The CMA's ruling permits an additional £556 million in revenue, which is only 21% of the £2.7 billion the companies initially requested.
Financial Implications for Consumers
The approved increases will result in varying average annual bills for customers of the affected companies. Anglian Water's average bill will rise to £599, Northumbrian Water to £495, South East Water to £286, Southern Water to £638, and Wessex Water to £622. The increases are intended to help the companies meet regulatory and environmental obligations, including reducing sewage pollution and upgrading infrastructure.
Background and Context
In December 2024, Ofwat set price controls for the 16 regulated water companies for the period from 2025 to 2030, forecasting an average bill increase of 36%. The five companies contested these determinations, arguing they were insufficient to meet their regulatory requirements. The CMA's independent group reviewed extensive evidence from the companies, Ofwat, and over 40 third parties, including consumer and environmental groups.
Official Statements & Responses
Kirstin Baker, chair of the CMA's independent panel, stated, “We’ve found that water companies’ requests for significant bill increases, on top of those allowed by Ofwat, are largely unjustified. We understand the real pressure on household budgets and have worked to keep increases to a minimum, while still ensuring there is funding to deliver essential improvements at reasonable cost.” Water Minister Emma Hardy acknowledged public anger over rising bills and emphasized the need for water companies to support struggling customers.
Criticism & Opposition
The decision has faced significant backlash from consumer advocates and environmental groups. Mike Keil, chief executive of the Consumer Council for Water, expressed concern that the increases would burden households already facing financial pressures. He noted that many customers are still adjusting to previous bill hikes and warned that they might pay more without seeing improvements in service. Environmental advocates criticized the companies for returning cash to shareholders while failing to address ongoing pollution issues.
What's Next
The CMA's provisional decision will undergo further consultation before final determinations are made in 2026. Meanwhile, the UK government is considering reforms to the water sector, including the establishment of a new regulatory body to replace Ofwat, amid ongoing discussions about the need for systemic changes to address the challenges facing the industry.
Conclusion
The CMA's ruling represents a significant moment for the UK water sector, balancing the need for increased funding for infrastructure and environmental improvements against the financial strain on consumers. As the situation evolves, stakeholders will be closely monitoring the implications for both water companies and their customers.
