Thames Water is in crisis. The UK’s largest water company has accumulated £17.6 billion of debt since privatisation and is locked in talks with the government over a rescue deal.
The deal could hand control of the water supply for 16 million people to a consortium of hedge funds led by Elliott Investment Management, founded by Paul Singer, who donated $5 million to Donald Trump’s Super PAC and tens of millions more to Republican causes in 2024.
Elliott is reportedly demanding that Thames Water be let off environmental fines for four years – potentially worth up to £1 billion – and is asking for leniency on pollution and leakage targets as conditions of its involvement. The government, reportedly terrified of a bond market crisis if Thames collapses, appears to be considering it.
The story has been reported by the Guardian this week and it is worth reading in full. But for Southern Water customers in Brighton and Hove, one detail stands out above all others.
Macquarie Asset Management, the Australian infrastructure investor that currently owns 82% of Southern Water, previously held a major stake in Thames Water. It left that company carrying an estimated £2 billion of additional debt. Macquarie then moved on to Southern Water, where the same pattern is visible: debt at around 70-80% of the regulated asset base, bills rising faster than any other company in the country, and a 2-star Environment Agency rating.
This is not a coincidence. It is a business model. Buy a water monopoly, load it with debt, extract returns, raise customer bills to service that debt, and move on. Customers have no choice of provider. The regulator has been, in the words of the Guardian’s report, “heavily criticised for opening the door after 2010 to allow private equity and international hedge funds to take over England’s water companies.”
Seven out of ten privatised water and sewerage companies in England are now controlled by private equity investors. A similar number are in foreign ownership. Your water bill is, in part, servicing that debt and generating those returns.
This is what you are paying for. This is why withholding payment is a legitimate response.
