Why Are UK Water Bills So High? Time to Challenge Water Company Profiteering

Water Bill

As a UK consumer, I’m increasingly alarmed every time my water bill lands on the doormat. Water is a basic human right; yet, for millions of households across England and Wales, the cost of this essential service continues to rise. Meanwhile, headlines about water company profits, executive bonuses, and environmental failures make it hard not to feel exploited. Why are our water bills so high, and what can be done to make water affordable for everyone?

The State of Water Pricing in the UK

Let’s look at the facts. According to Ofwat, the water regulator, the average household water and sewerage bill in England and Wales for 2023/24 is £448 per year, up from £405 in 2010. That’s a 10% rise in just over a decade, outpacing inflation for much of that period. In some regions, bills are even higher: South West Water customers pay an average of £476, while Wessex Water charges £504.

These increases come at a time when many families are struggling with the cost-of-living crisis. The Consumer Council for Water (CCW) estimates that 1 in 5 households in England and Wales now find their water bills unaffordable.

What’s Driving Up the Cost?

Water companies and their defenders point to several factors:

  1. Ageing Infrastructure: Much of the UK’s water network dates back to Victorian times. Ofwat estimates that £51 billion will be needed over the next five years to upgrade pipes, treatment works, and reservoirs.
  2. Environmental Standards: Companies are required to meet strict standards for water quality and environmental protection, including reducing pollution and leakage.
  3. Population Growth and Climate Change: The increasing number of people and less predictable rainfall put pressure on water supplies, necessitating investments in new sources and conservation efforts.

But these explanations don’t tell the whole story. Many consumers feel that water companies are using these challenges as cover for excessive profits and poor performance.

Are Water Companies Exploiting Consumers?

Since privatisation in 1989, England and Wales’ water industry has been run by private, mostly foreign-owned companies. In that time, water bills have risen by 40% in real terms (after inflation), according to the National Audit Office. Meanwhile, water companies have paid out over £72 billion in dividends to shareholders—an average of £2 billion a year.

In 2022, Thames Water paid £37 million in dividends, despite reporting a £82.6 million pre-tax loss and being responsible for 370,000 hours of raw sewage discharges into rivers. The company’s CEO, Sarah Bentley, received a pay package of £1.6 million before stepping down amid public outrage.

The pattern is repeated across the sector. In 2023, the Financial Times reported that the nine major water companies paid their top executives a combined £15 million in salaries and bonuses, even as they faced record fines for pollution and missed leakage targets.

The Human and Environmental Cost

The impact on households is stark. The CCW found that 5.7 million people in England and Wales are now struggling to pay their water bills. Water poverty is a growing issue, with some families forced to choose between paying for water and other essentials.

At the same time, the environmental record of water companies is abysmal. In 2022, water firms dumped raw sewage into rivers and seas for over 2.4 million hours, sparking public health fears and damaging wildlife. The Environment Agency called the sector’s performance “the worst we have seen for years.”

What Needs to Change?

So, what can be done to make water more affordable and ensure companies serve the public, not just shareholders?

1. Stronger Regulation and Penalties

Ofwat must be empowered to cap dividends and executive pay when companies fail to meet performance targets. Fines for pollution should be much higher and invested directly into environmental restoration.

2. Greater Transparency

Water companies should be required to publish detailed accounts showing exactly how much is spent on infrastructure, dividends, and executive pay. This would allow consumers and regulators to see where their money goes.

3. Public Ownership or Not-for-Profit Models

Scotland’s water is publicly owned and not-for-profit. Scottish Water charges an average of £384 per year—significantly less than most English companies—while investing more per customer in infrastructure. Bringing English and Welsh water back into public hands, or at least adopting not-for-profit models, could prioritise investment and affordability over shareholder returns.

4. Social Tariffs and Support Schemes

Water companies should expand social tariffs and hardship funds for low-income households. Ofwat should make it mandatory for all companies to offer meaningful support, not just voluntary schemes.

5. Investment in Leakage Reduction and Efficiency

UK water companies lose over 2.4 billion litres of water every day through leaks—enough to supply 15 million people. Reducing leakage would cut costs and help keep bills down.

Conclusion: Water Is a Right, Not a Commodity

Water is not a luxury. It’s a basic human need. Yet, the current system allows private companies to profit while too many families struggle to pay and our rivers run with sewage. As consumers, we must demand change: stronger regulation, greater transparency, and a serious debate about public ownership.

It’s time to put people and the environment before profits. Water companies must be held accountable, and water must be made affordable for all. Our health, our wallets, and our environment depend on it.
