Water and council tax rises tighten the squeeze on UK household budgets

Households across England and Wales are grappling with another round of rises in essential bills, as higher water charges and council tax increases add to the pressure on already stretched family budgets.

The average water and wastewater bill has climbed by around £33 to £639 a year for 2026-27, a 5.4% increase, while the typical Band D council tax bill in England has risen to £2,392, up almost 5% on the year.

Together with the looming July energy price rise, the increases mean many households are seeing the cost of simply keeping their homes running climb faster than their incomes.

Water bills keep climbing

Water companies say the higher charges are needed to fund a major programme of investment in ageing infrastructure, with tens of billions of pounds earmarked for upgrades by the end of the decade to tackle leaks, sewage spills and supply resilience.

The increases are far from uniform across the country. Customers of United Utilities in the North West face the largest rises, averaging around £57, followed by Southern Water customers at about £55, with several other suppliers not far behind.

Consumer groups have voiced frustration that bill payers are being asked to fund improvements after years of criticism over the industry's environmental record and the dividends paid to shareholders.

The anger is sharpened by repeated revelations about sewage discharges into rivers and seas, which have made water companies a lightning rod for public discontent. Critics argue that customers are now paying twice: once through higher bills and again through the environmental cost of years of under-investment.

Council tax passes another milestone

Council tax has risen again as local authorities grapple with mounting financial pressures, particularly the cost of social care and homelessness services. Most councils are capped at increases of around 5% without a referendum.

However, the government granted a handful of councils facing severe financial difficulty special permission to exceed that cap, meaning some residents face even steeper rises than the national average.

Local government leaders warn that even these increases will not be enough to plug the gaps in their budgets. Years of rising demand for adult and children's social care, combined with constrained central funding, have left many authorities warning of effective bankruptcy without further support.

• Average water and wastewater bill: £639, up £33 (5.4%)
• United Utilities customers face the largest rises, around £57
• Southern Water bills up about £55
• Average Band D council tax in England: £2,392, up £111 (4.9%)
• Several councils granted permission to exceed the 5% cap

The combined effect is a meaningful hit to disposable income, particularly for households on fixed incomes or those who do not qualify for support schemes designed to cushion the most vulnerable.

“These are not optional costs. Water and council tax are unavoidable, and when they rise faster than wages, families have no choice but to cut back elsewhere or fall into arrears.”

Help available

Support exists for those who struggle. Many water companies offer social tariffs and hardship schemes for low-income customers, while councils provide council tax reduction schemes and discretionary support, though take-up of both is often patchy.

Advice charities urge households facing difficulty to check their eligibility for discounts and to contact providers early rather than letting arrears build up, which can lead to enforcement action.

Single-person households can claim a 25% discount on their council tax, while pensioners, carers and those on certain benefits may qualify for further reductions. Campaigners say millions of pounds in support goes unclaimed each year simply because people are unaware they are entitled to it.

Background

Water bills in England and Wales are set within a regulatory framework that allows companies to raise charges to fund agreed investment, while council tax is set locally within limits laid down by central government.

Both have become flashpoints in the cost-of-living debate, symbolising the steady creep of unavoidable costs that fall on every household regardless of income. The council tax system itself, still based on property valuations from decades ago, has also drawn renewed calls for reform.

What happens next

With the regulator overseeing a multi-year investment settlement for the water industry and councils warning of continued financial strain, further above-inflation rises in both bills look likely in the years ahead, keeping them firmly on the political agenda.

Whether the government opts for fundamental reform of either system, or simply manages the pressures year by year, will shape how heavy these unavoidable bills become. For now, households are left to absorb the latest increases on top of every other cost they face.
