Water bills for millions of households in England and Wales will increase from April 1, 2026, with average annual charges rising by £33. The change represents a 5.4% increase and forms part of a broader pricing framework approved by regulators. The rise comes at a time when many families are already managing higher living costs, placing renewed focus on utility affordability.
Regional Variations and the Drivers behind Rising Costs
The scale of the increase varies significantly depending on location and provider. According to reporting from Mirror Money, Anglian Water customers will see bills rise to £674, an increase of £44, while Southern Water customers will pay £759, up by £55. In contrast, Thames Water customers face a comparatively small increase of £3, bringing annual bills to £658.
Other notable changes include Severn Trent Water, where bills will rise by £52 to £587, and United Utilities, where customers will pay £660, an increase of £57. Welsh Water customers will see bills increase by £31 to £683, reflecting a 5% rise.
Water-only providers also show variation. According to the same report, Affinity Water customers in the central region will face a 13% increase, taking bills to £266, while those in the east region will see only a marginal rise of £1. Portsmouth Water remains among the lowest, with bills increasing by £13 to £162.
These increases are part of a longer-term plan approved by regulator Ofwat, allowing companies to raise bills by an average of 36% over five years to 2030. According to Water UK, the industry body, the additional revenue is intended to support a £104 billion investment programme aimed at improving infrastructure, securing water supplies, and reducing sewage discharges into rivers and coastal waters.
Water companies have faced sustained criticism over pollution incidents, particularly the discharge of untreated sewage. The investment programme is framed as a response to both environmental pressures and ageing systems, though public concern over accountability remains.
Support Measures and Ways Households Can Reduce Costs
The increases are expected to place added pressure on household budgets, particularly for lower-income families. According to Water UK, around 2.5 million households will receive financial support, with average discounts of approximately 40% on their water bills.
David Henderson, chief executive of Water UK, stated that while bill increases are unwelcome, they are necessary to fund essential upgrades. He noted that support schemes are being expanded to mitigate the impact on vulnerable customers.
Households also have options to manage their usage and potentially lower costs. According to consumer advice cited in the report, reducing daily water use can have a measurable effect. Simple steps such as shortening showers or turning off taps when not in use can contribute to savings over time.
Water-saving devices are available in some regions through initiatives such as Save Water Save Money, offering items like regulated shower heads and tap inserts at no cost. Eligibility depends on location, but such schemes aim to encourage more efficient consumption.
Installing a water meter may also reduce bills for some households. Advice attributed to Martin Lewis suggests that properties with more bedrooms than occupants could benefit financially from switching to metered billing, as charges would then reflect actual usage rather than property value.
