It is part of a wider overhaul of a privatised sector criticized for paying dividends and piling on debt while sewage spilled into rivers. The UK government wants to put a legal ceiling on how much debt water companies can take on, tackling head-on a problem that has dogged England's privatised water industry for years. Ministers plan to make debt limits legally binding as part of a coming overhaul of the sector, [The Guardian reported](https://www.theguardian.com/business/2026/jul/10/legally-binding-debt-targets-england-water-companies), a first since the industry was privatised in 1989. ## What is being proposed The plan targets what regulators call "gearing," the level of a company's debt relative to the value of its assets. The water regulator, Ofwat, has long suggested gearing should stay below around 55%, a level seen as financially prudent, but that guidance has been just that: advisory. Some companies have run far above it. Under the new approach, the limit would carry the force of law, and a company that breaches it would have to answer to ministers, with sanctions to follow if it did not bring borrowing down. Crucially, the government has not yet fixed the exact number, a sign it is still weighing how strict to be. The measure is expected to form part of broader legislation to reshape how the sector is run. ## Why gearing matters in a monopoly High debt is especially fraught in water because each company is a regional monopoly: households cannot switch supplier. Ofwat sets the prices customers pay based partly on companies' costs, including the cost of servicing debt. So when a company borrows heavily, and particularly if it also pays out dividends to shareholders, the burden can ultimately land on customers' bills, while the risk of financial distress grows. That is the pattern critics have attacked. Across the industry, water companies have paid out tens of billions of pounds in dividends since privatisation even as their debts climbed and, opponents argue, investment in pipes and treatment lagged. The visible result has been a wave of sewage discharges into rivers and seas that has provoked public anger. ## The Thames Water warning The company that turned this into a crisis is Thames Water, Britain's largest water supplier. It has been weighed down by around 20 billion pounds of debt and pushed to the brink of collapse, forced into emergency financing and raising the prospect of temporary nationalisation. Its troubles, more than any policy paper, are what have made the case for hard limits on borrowing. A company providing an essential public service should not, the argument runs, be able to gamble its finances to the point where the state may have to step in. ## The wider overhaul The debt limits are one piece of a larger reform following an independent review of the water sector led by Sir Jon Cunliffe. The government has signaled plans to replace Ofwat with a stronger, single regulator and to tighten oversight of pollution and company conduct. The common thread is a shift from light-touch supervision toward firmer rules, after years in which regulators were seen as too willing to trust companies to police themselves. ## Why it matters For UK households, the stakes are direct: who pays, and how much, for water and for cleaning up rivers. For investors and the wider utilities sector, binding debt limits mark a meaningful change in the risk of owning a regulated monopoly, constraining the financial engineering that made water attractive to some buyers. And for other countries wrestling with how to run privatised essential services, Britain's attempt to rein in utility debt will be a closely watched test of whether tighter rules can fix what looser ones did not.
