Thames Water’s £1m Dilemma: Executive Pay Collides with a Utility on the Brink 

Thames Water is already under intense scrutiny over executive remuneration, environmental performance and the use of emergency funding.

Thames Water has found itself at the centre of a fresh political and corporate storm after paying its finance chief, Steve Buck, a £1m signing-on fee while Britain’s largest water company continues to fight for financial survival. 

The payment, made at the end of July, comes at a particularly sensitive moment for the utility. Thames Water is carrying a debt pile of roughly £21bn, remains dependent on emergency financing and is facing the possibility of being placed into a special administration regime if efforts to secure a private-sector rescue fail. The company provides water and wastewater services to around 16 million people across London and the Thames Valley. 

Buck joined Thames Water as chief financial officer in April 2025, returning to a company where he had previously worked earlier in his career. Before his appointment, he had held senior finance positions at Pennon Group, Anglian Water and Centrica. Thames Water said at the time that his experience in regulated and capital-intensive businesses would be important as it attempted to strengthen its finances and deliver a wider turnaround. 

The £1m payment was not made when Buck joined. It was deferred and was eventually paid after Thames Water obtained legal advice on its contractual obligations. According to reports, the payment formed part of the recruitment package designed to persuade Buck to take the role during an exceptionally uncertain period for the business. 

That distinction may be legally important, but it does little to soften the political optics. 

The money was reportedly drawn from an emergency debt package provided by Thames Water’s creditors. The company has been relying heavily on emergency liquidity while creditors and the government consider competing options for its future. In July, Thames Water said commitments under its super senior financing arrangements had reached £2.323bn, with plans to seek additional funding that could eventually take the facility to £3bn. 

For critics, the timing is difficult to defend. Thames Water is already under intense scrutiny over executive remuneration, environmental performance and the use of emergency funding. The company is among water firms facing restrictions on performance-related bonuses because of continuing environmental shortcomings. At the same time, Thames Water has previously disclosed millions of pounds in payments to senior managers under various remuneration and retention arrangements. 

The company’s financial position makes the controversy even sharper. Thames Water has been struggling for years with excessive leverage, infrastructure problems and regulatory pressure. Its creditors are now effectively driving the rescue process, while the government is weighing whether private-sector restructuring can deliver adequate protection for customers. 

A consortium of creditors has proposed a major rescue plan involving fresh equity, additional borrowing and the restructuring of existing debt. The proposal also includes a government “golden share”, intended to provide greater public oversight while avoiding outright nationalisation. The plan is widely viewed as an attempt to prevent Thames Water from entering special administration. 

The executive-pay dispute therefore reflects a much larger question about how distressed essential-service companies should reward senior leadership. 

There is a legitimate argument that experienced financial executives are particularly valuable when a company is attempting to negotiate with creditors, regulators and government while restructuring billions of pounds of debt. Thames Water itself appointed Buck specifically for his experience in financial restructuring, capital markets and regulated industries. Recruiting such expertise during a crisis can come at a premium. 

Yet the £1m payment also highlights the tension between commercial employment practices and public expectations. When a company is dependent on emergency financing and its long-term ownership remains uncertain, large executive payments can easily become a symbol of wider governance concerns.
