Regulator Proposes Extra 3% Bill Rises for Five Water Companies to Fund Upgrades
Households served by five major water companies in England and Wales may soon face an additional 3% rise to bills after the Competition and Markets Authority (CMA) issued a provisional ruling allowing extra charges to support infrastructure spending. The CMA says the decision is provisional and subject to a public consultation process. The Financial Times has provided the primary reporting on the CMA determination.
Who is affected and why
The CMA’s provisional ruling affects Anglian Water, Northumbrian Water, Southern Water, South East Water and Wessex Water, which together serve roughly 14.7 million households. The regulator said the extra revenue, if approved, would help fund long-term maintenance, reduce leakages and support resilience improvements across ageing networks.
As part of the provisional decision, the CMA also indicated a modest increase in the allowed rate of return for these firms, from 4.03% to 4.29%, giving them slightly more headroom to finance capital projects. The CMA emphasised the proposal remains subject to stakeholder feedback during the consultation period before any final determination is made.
Companies’ case and regulator’s reasoning
The water companies involved told regulators that previously approved price rises and returns were insufficient to meet the scale of capital investment required. They argued that without additional revenue, necessary projects could be deferred and service standards would suffer. The CMA said it accepted that a case had been made in principle for extra allowances but stressed the decision would be finalised only after consultations and careful scrutiny of costs and outcomes.
Consumer and political pushback
Consumer groups and political figures warned that any increase would add to household pressures amid broader cost-of-living strains. Campaigners said households already face high energy, mortgage and food costs, and called on regulators to ensure any additional charges were strictly linked to demonstrable improvements in service and leak reduction.
Some politicians urged the government and regulators to hold firms to clear performance targets before allowing further bill increases. Others stressed the importance of transparent reporting so customers can see how extra revenue is spent on repairs, resilience and environmental protections.
Context: previous rises and regulatory framework
This CMA action comes on top of previous approvals by the water regulator Ofwat, which in recent years has permitted notable rises in bills to finance long-term investment programmes addressing sewer and pipe maintenance. Ofwat and the CMA operate different roles: Ofwat sets price controls, while the CMA can review specific appeals and special cases where firms argue that allowed returns are inadequate.
Regulatory decisions on water pricing balance the need for investment in infrastructure against affordability for customers. The recent provisional decision reflects ongoing tensions in the sector between long-term capital needs and short-term household budgets.
Next steps and consultation
The CMA’s decision is provisional and will be followed by a period of public consultation. Households, consumer groups, local authorities and other stakeholders will be able to submit responses and objections during the consultation window. The CMA said it will review responses before issuing a final ruling.
Key items to monitor include:
- the final CMA determination after consultation;
- whether Ofwat or the Treasury responds with measures to cushion vulnerable customers;
- the specific performance conditions and delivery targets attached to any extra funding;
- how companies report progress on leakage reduction and infrastructure upgrades.
Why this matters
The provisional ruling highlights a persistent challenge for the UK’s water sector: how to fund necessary upgrades to ageing infrastructure in an era of extreme weather, regulatory scrutiny and political sensitivity around household bills. The final outcome will have implications for household finances, company investment plans and the pace of efforts to reduce leaks and improve resilience as climate pressures increase.
