From April 1st, water bills in England and Wales will increase by an average of £123 per year. This signifies a significant increase in household water costs, directly impacting residents' living expenses.
The average annual water bill will reach £603, but there are significant differences in charges between different water companies. It is worth noting that household users cannot choose their water supplier, which makes them relatively passive in bearing the increase in water bills. The average water bill increase is about £10 per month, from £40 to £50, but millions of households face even higher increases.
Specifically, Southern Water customers will face an increase of up to 47%, with annual water bills reaching £703. Hafren Dyfrdwy and South West Water will also see their water bills increase by 32%. Thames Water customers have been informed that their water bills will increase by 31%, while Yorkshire Water will increase water bills by 29%. Bournemouth Water customers will also face a 32% increase in bills.
Water companies explain that the reason for the increase in water bills is the need for additional funds to replace aging, leaking pipes and reduce sewage discharge into rivers and oceans. At the same time, public scrutiny of water companies' environmental and financial performance, as well as executive bonuses and compensation, is also increasing. There are many disagreements between water companies and the water regulator Ofwat on the issue of price increases. Ofwat previously stated that water companies could increase water bills by an average of £31 per year over the next five years, and that these increases would be mainly concentrated in the initial period.
Users can save on water bills in a variety of ways. Households with water meters only pay for the actual amount of water used, plus a fixed fee. Customers without water meters pay a fixed fee, usually based on the rateable value of the property. All households are required to pay for sewage treatment services, which may be included in the water bill or charged separately. In addition, users can reduce water bills by conserving water, checking bills, and installing water meters. If household income is low, they can also apply for low-income subsidy programs provided by water companies. Some households may be eligible for sewage service refunds if they can prove that they do not use certain sewage treatment services.
Water companies say they will also set aside more than £4 billion to fund social care tariffs—water bill discounts for vulnerable groups. But the Consumer Council for Water (CCW), which represents the interests of users, believes that this level of support is far from enough, as approximately 2.5 million households are already in arrears with water companies. When conducting price reviews, Ofwat sets performance targets to encourage water companies to fulfill their commitments to customers and the environment. These targets include reducing leaks, pollution incidents, and sewage flooding. If companies exceed their targets, they may receive financial rewards; if they fail to meet their targets, they may face penalties. These costs are ultimately reflected in annual adjustments to customer bills. In 2024-25, water companies will need to repay £114 million.
