Britain’s largest water supplier faces backlash after millions in executive rewards are revealed while customers endure sewage failures and financial uncertainty
Thames Water has intensified scrutiny over executive pay after revealing more than £4 million in bonuses and retention awards were handed to senior management despite the company remaining on the brink of a financial rescue.
The UK’s largest water supplier, carrying a debt burden approaching £20 billion, disclosed that payments to key management personnel reached £4.09 million in the year to March 31 — a sharp increase from £2.8 million the previous year.
The payments came as the company attempts to stabilise its finances, secure fresh investment and avoid a potential temporary return to state control.
Chief executive Chris Weston saw his total remuneration rise to £1.16 million, up from £1.04 million the previous year. His package included a £99,000 retention payment deferred from an earlier period, while his basic salary increased by 14 per cent to £995,000 from April.
Environment Secretary Emma Reynolds criticised the payments, accusing the company of rewarding executives while customers continue to face years of complaints over leaks, sewage discharges and poor service.
She said: “It’s outrageous that one of the worst-performing water companies is handing out bonuses and inflation-busting pay rises to its executives.”
The minister said the payments undermined public confidence and warned the Government would act against companies attempting to bypass restrictions on executive rewards.
“We’ve banned bonuses for polluting water bosses and will be taking action to prevent bonuses by any other name,” she added.
The controversy follows the introduction of the Water (Special Measures) Act, which allows regulator Ofwat to block performance-related bonuses for executives at companies failing customers and environmental standards.
Thames Water insists Mr Weston’s retention payment was agreed before the legislation came into force and said he did not receive a performance-related bonus for 2025-26.
However, critics have questioned whether retention schemes amount to a way around restrictions designed to hold water executives accountable.
The company previously agreed to pause £2.46 million in retention payments for 21 senior executives following public criticism.
Thames Water argues that retaining experienced leadership is essential as it attempts the biggest infrastructure overhaul in generations.
Its remuneration committee said restrictions on executive pay could make it harder to retain leaders capable of delivering the company’s transformation.
But the argument has done little to ease anger among customers and politicians, who argue that executives should not benefit from large rewards while the company remains burdened by debt and operational failures.
The dispute highlights the wider crisis facing Britain’s privatised water sector, where financial restructuring, environmental performance and public trust have become increasingly intertwined.
