The average household is expected to see a rise in water bills from £448 to £542 annually by 2030, representing a 20% increase before inflation adjustments. This move, announced by the water regulator Ofwat, is part of a broader strategy to fund critical upgrades to water infrastructure and environmental improvements.
Water Bill : Tackling Pollution and Securing Supplies
The proposed increase is driven by a need to address the “twin crisis” of water pollution and shortages. Ofwat has approved plans for an £88 billion investment to enhance service quality and protect natural resources. These funds will support upgrades to aging infrastructure and initiatives to prevent untreated sewage from entering rivers and seas.
Environment Secretary Steve Reed criticized previous regulatory decisions, blaming insufficient investments for the current crises. “We are facing this twin crisis of water pollution and water shortages because the Conservatives refused to invest to upgrade crumbling water infrastructure. Instead, they let water companies divert customers’ money to line the pockets of their executives and shareholders.”
“This week the independent water regulator will announce water bill rises to repair the damage. The public are right to be angry.” he wrote, emphasizing the government’s need to balance service improvements with affordable pricing.
Affordability and Consumer Concerns
The proposed water bill increases have sparked concerns over their impact on household budgets, with significant numbers of consumers already struggling to pay current rates. Research from the Consumer Council for Water (CCW) reveals that 39% of households in England and Wales will find the increases difficult to afford, placing millions at financial risk. The average bill is projected to rise from £448 to £542 annually by 2030, an increase of £94 before inflation adjustments.
Water companies have proposed measures to expand financial support for those affected. They aim to increase the number of households receiving assistance from 1.6 million to 3 million by 2030. At present, just 8% of customers benefit from social tariff schemes, but Ofwat has called for broader coverage during the 2025–2030 period to address the mounting affordability challenge.
Consumer advocacy groups remain critical of the proposed measures, citing inconsistencies in the existing support system. Citizens Advice has identified a “postcode lottery” in social tariff availability, where eligibility depends on local factors, and many eligible households are unaware of these programs. Advocacy efforts are now focused on creating a unified, nationwide system to ensure equitable access to relief as water costs continue to rise.
