Wessex Water awarded its chief executive an above-inflation pay increase even as the company was banned from paying bonuses because of sewage spills, sparking renewed outrage over water industry executive compensation. Ruth Jefferson received a 14% base salary increase in October, from £590,000 to £670,000, before other benefits, according to accounts published this month. The raise far exceeded the 3.5% given to workers and put her pay at 18 times that of the company’s median employee.
How Executive Pay Compares to Workers
The disparity between CEO pay and employee wages has become a flashpoint in the water industry. While Jefferson’s base salary jumped to £670,000, her full pay packet for the year reached £791,000 once pension and unspecified benefits were included. She had received £440,000 the previous year for six months while serving as chief compliance officer and then chief executive. Meanwhile, Wessex Water workers received a modest 3.5% increase, highlighting the growing gap between top executives and frontline staff.

| Base Salary (2025) | £670,000 | £33,925 |

Bonus Ban and Sewage Spills Controversy
Water industry executive pay has come under intense scrutiny in recent years amid public outrage over sewage spilling into Britain’s rivers and seas. The government introduced a bonus ban in 2025 for companies responsible for serious pollution or which failed financial tests. Wessex Water revealed in its report that it expected to fall foul of the bonus ban “particularly in relation to environmental and operational metrics.” Despite this, the company proceeded with Jefferson’s substantial pay rise, drawing criticism from consumer groups and environmental advocates.
Anglian Water’s Retention Payment
Another water company, Anglian Water, awarded its chief executive, Mark Thurston, a £500,000 “retention payment,” despite being banned from paying bonuses. The payment to the former HS2 railway boss was made by Anglian’s parent company, which claimed it was allowed because the bonus was not linked to performance. Anglian said the payment did not replace bonuses and was made to Thurston in July 2025 from funds that would otherwise have been paid to shareholders “to ensure his retention until January 2027.” The annual report stated it had a “long-held, steadfast view that banning bonuses is not helpful” and it would be “more effective to focus on rewarding improvement.” An Anglian Water spokesperson said it paid “targeted, time-limited retention awards” to key executives.
