Southern Water bosses’ pay: bonuses blocked as bills rise and pollution failures continue

The chief executive and finance director received no annual bonus for the second year running. But Southern Water’s accounts show why the word “bonus” tells only part of the story—and why customers should look at total pay, old incentive plans, new salary rises and the performance figures underneath.

Three documents landed within ten days of each other, and together they tell a story that none tells properly on its own.

On 15 July 2026, Southern Water signed off an annual report describing a company in transformation. It spoke of falling leakage, fewer supply interruptions, record investment and a management team carrying an unusually difficult job. Two days later, Canterbury Crown Court fined the company £7.1 million for historic pollution offences that shut beaches, damaged coastal communities and exposed failures in equipment and oversight. The offences dated from 2019 to 2021 and predated Lawrence Gosden’s appointment as chief executive, but the sentence returned Southern Water’s past to the front page just as its latest accounts tried to move the story forward.

Then, on Friday 24 July, the Guardian published an industry-wide investigation into water bosses’ pay. Across 14 major companies, reported packages for chief executives and finance directors rose by 1.5% to £25.3 million. Eight companies expected the statutory performance-pay ban to apply to them. Southern Water was one of the companies where reported executive pay fell, not rose.

Southern Water cannot fairly be accused of doing precisely what the Guardian found elsewhere. Its chief executive’s Lawrence Gosden (pictured below right) reported package dropped from £1.378 million in 2024/25 to £736,400 in 2025/26. Chief financial officer Stuart Ledger’s (below left) fell from £986,700 to £483,100. Both annual-bonus columns contain the figure the public was promised: zero.

     

But the zero is only the start of the story.

The money that wasn’t paid

Buried beneath Southern Water’s remuneration table is a footnote explaining what the two executives would have received without the ban. Gosden’s calculated annual bonus was £388,622. Ledger’s was £240,298. Together, the rule stopped £628,920 from being paid.

That is not theatre. It is a real financial consequence. Southern Water had one Category 1 pollution incident at Florence Farm in September 2025, so Ofwat’s Performance Related Pay Prohibition Rule applied. The company says the incident was serious enough to make annual bonuses unavailable regardless of how the rest of the scorecard turned out.

The same thing happened a year earlier. A Category 1 incident in the New Forest blocked calculated bonuses of £396,475 for the chief executive and £335,442 for the finance director. Across the two years, the prohibition removed more than £1.36 million in annual bonuses from those two packages. Ofwat says its rule stopped more than £4 million across the sector in its first year.

So the ban works. The harder question is what, exactly, it works on.

Ofwat’s rule prohibits performance-related pay to directors on the regulated company’s board when specified consumer, environmental, financial-resilience or criminal-liability tests are triggered. It does not impose a pay cap. It does not freeze salaries. It does not automatically reduce pensions, housing allowances, car benefits or the fees paid to non-executive directors. And whether a long-term award is caught can depend on the rules in force when the scheme began.

This is where Southern Water’s earlier accounts become important.

The £1.2 million award that survived the first ban

In 2024/25, the annual bonuses were prohibited. Yet Gosden’s total package rose by about 80%, from £764,200 to £1.378 million. Ledger’s rose by roughly 62%, from £610,000 to £986,700.

The reason was a two-year Long-Term Incentive Plan (LTIP) established in 2023, before the statutory prohibition applied. Southern Water awarded £691,200 to Gosden and £534,240 to Ledger under that scheme—a combined £1.225 million. The company said the money was funded by shareholders, not customers, and was payable in two instalments. The annual bonus was barred; the older LTIP remained.

That was lawful under the framework then operating. It should not be described as Southern Water secretly breaking the bonus ban. The company disclosed the arrangement, explained why it sat outside the new prohibition and showed the award in the audited single-pay figure.

But it exposed the weakness of political language. Ministers said “bonuses” were banned. The public naturally heard: executives will not receive performance rewards when their company causes serious pollution. The accounts showed something narrower: one category of annual reward was blocked while a pre-existing long-term performance award could still be recognised.

The distinction between an annual bonus and an LTIP is meaningful to remuneration committees, lawyers and accountants. It is much less meaningful to a customer whose bill has risen by hundreds of pounds, or to someone standing beside a polluted stream.

Reported pay then fell sharply in 2025/26 because no new LTIP amount appeared in the single-figure table. That explains most of the apparent improvement. It was not caused by the base salaries moving down. Gosden’s salary rose to £518,162 and Ledger’s to £400,496. Their fixed packages, including benefits and pensions, were £736,434 and £483,084 respectively.

The benefits also deserve daylight. Gosden received £140,548 in benefits, including a monthly housing allowance, car allowance and private medical insurance. Ledger received £38,533, covering a car, mobility allowance, medical insurance and a one-off payment for accrued leave.

From 1 April 2026, both base salaries rose by another 3.5%, taking the chief executive to £536,298 and the finance director to £414,513. The company says this matched the wider workforce award and remained below its new desired market position. The incoming chair’s annual fee was set at £300,000, while the standard non-executive fee rose from £55,000 to £60,000.

None of that breaches the bonus rule. That is precisely the point. A bonus ban can reduce pay without settling the much larger argument about what the people running a monopoly essential service should earn, how much should be fixed, and what standard of service should be required before the larger rewards begin again.

The performance beneath the package

Southern Water’s latest Annual Performance Report is not a catalogue of unrelieved failure. It records real improvements, some of them substantial. But it also makes clear why the company’s executives received no annual bonus.

The top-line result is stark: Southern Water achieved 36% of its reported performance commitments. It met or outperformed eight of 20 shared operational commitments, excluding the separate customer and developer experience measures. Its Board said the overall penalty for the year was £29.7 million, to be reflected in future revenues and therefore in 2027/28 bills.

Pollution remains the hardest fact to get around. Southern Water recorded 254 wastewater pollution incidents during 2025, including one Category 1 incident, 11 Category 2 incidents and 242 Category 3 incidents. Twelve were classed as serious. Total incidents fell by about 5% from the previous year and serious incidents fell from 15 to 12, but both measures still missed their targets. The regulatory penalties were £17.13 million for serious pollution and £14.06 million for total pollution.

The company points to drought, record heat, low river flows and intense rainfall after prolonged dry weather. Those conditions can affect both the occurrence and environmental impact of incidents. It also says new incident-reporting guidance will increase the number recorded in future by bringing dry-day spills and previously excluded events into the system.

Weather matters. So do assets, maintenance and operational control. In the same report, Southern Water acknowledges that discharge-permit compliance deteriorated, internal sewer flooding worsened, sewer collapses increased and “operational grip” needed strengthening.

The environmental score used for executive bonuses tells its own story. Southern Water’s target began at two stars and stretched to three. The company received one star. The 20% environmental-performance component of the annual bonus scorecard therefore paid nothing.

Internal sewer flooding also paid nothing. The bonus scorecard recorded 389 incidents against a target of 314 and a stretch level of 264. Southern Water describes flooding inside a home as one of the worst service failures a customer can experience. Its performance commentary says blockages, especially fats, oils and grease, were a major cause, alongside hydraulic overloading during localised heavy rain.

Customer service was another red mark. Southern Water recorded 22,778 household complaints, equal to 108.48 complaints for every 10,000 connections. Its overall C-MeX score was 47.95. The company forecasts a £13.155 million penalty on that measure and says, with unusual directness, that it “didn’t get customer service right this year”.

There is a methodological caveat. Ofwat changed the C-MeX survey mix and moved more of it online, while scores fell across the industry. Southern Water says weaker performers were hit harder by the change. That may explain some of the fall; it does not erase 22,778 complaints or the company’s own acceptance that customers were not receiving the service they should.

How 96.7% becomes 54.2%

One table in the performance report demonstrates why headline percentages need to be taken apart.

Southern Water reports overall discharge-permit compliance of 96.7%. On its face, that sounds close to perfect. But the total combines two very different businesses. All 310 numeric water permits complied. On the wastewater side, 11 of 24 numeric permits failed, producing wastewater compliance of just 54.2%.

Both figures are technically correct. Only one describes the part of the business at the centre of the sewage argument.

This is not an accusation that Southern Water hid the lower number. It published both in the same regulatory table. The problem is how easily an overall percentage can become a reassuring headline while the material failure sits one row above it. A Long Read through the accounts has to do what corporate summaries rarely do: separate the components and ask which number answers the public’s actual question.

The same care is needed with the annual report’s finances. Revenue rose to £1.443 billion as higher allowed revenues and regulatory adjustments began funding the new investment period. Capital investment reached £1.167 billion. Yet the audited income statement recorded a £128.3 million loss, while net debt increased from £6.703 billion to £7.047 billion.

Southern Water also received £900 million of new shareholder equity, with a further £300 million committed, and paid no external dividend for the ninth consecutive year. Those facts complicate the familiar caricature of a company simply stripping cash out through dividends. The current problem is not a dividend leaving the regulated company. It is whether a heavily financed private structure can convert record spending into reliable, clean service quickly enough—and who bears the cost while that conversion happens.

The improvements are real

An honest assessment cannot stop at the red figures.

Annual leakage fell by 11.5% to 89.8 million litres a day. The three-year average improved to 101.1 million litres a day, enough to earn a £1.07 million regulatory reward. Water-supply interruptions lasting more than three hours fell from more than two hours per property in the previous year to five minutes and one second, earning £1.62 million.

External sewer flooding fell to 2,507 incidents, Southern Water’s lowest recorded level, producing a £30.82 million reward. The company says its expanding network of sewer-level monitors, preventative cleaning, root cutting and machine-learning alerts are helping it identify problems before they become floods.

Storm-overflow releases recorded by monitors fell from 29,355 in 2024 to 15,554 in 2025. Rainfall influenced the comparison, but the company also points to surface-water separation, upgraded monitoring and local projects. Its bathing-water score met the Ofwat target, with 49 sites rated excellent, although nine of the 87 sites in the measure remained poor.

These are not public-relations inventions. They are disclosed regulatory results. They show why Southern Water’s remuneration committee could calculate a sizeable theoretical bonus even in a year when the payment was ultimately prohibited. The scorecard gave credit for drinking-water quality, leakage, energy generation, safety and financial performance, while customer satisfaction, the one-star environmental assessment, internal flooding and capital-delivery efficiency missed.

That is how corporate reward systems work: they divide one complicated year into weighted compartments. A company can fail badly in areas the public cares most about while still accumulating points elsewhere.

The prohibition rule overrode that arithmetic. Without the Category 1 incident, Gosden’s calculated award would have been nearly £389,000 and Ledger’s just over £240,000. That tells us the ban was not merely symbolic. It also tells us the underlying scorecard was prepared to reward the year despite a one-star environmental assessment, 12 serious pollution incidents, hundreds of internal floods and a customer score that attracted a forecast eight-figure penalty.

The bill arrives before the transformation

Customers do not experience Southern Water as a remuneration framework. They experience it through a tap, a toilet, a bill and, along the Kent and Sussex coast, the water beyond the beach.

The average combined Southern Water bill rose from £478 in 2024/25 to £703 in 2025/26, an increase of £224 or 47%, the largest percentage rise listed among England and Wales’s water-and-wastewater companies. From April 2026, Southern Water said the average combined bill would rise by another 8% to about £759 a year, or roughly £63.27 a month.

The company’s answer is investment. It says it is delivering an £8.9 billion business plan to 2030 and put more than £1.1 billion into assets during the first year. Higher bills, new equity and additional borrowing are funding work on pollution, water scarcity, leakage, treatment capacity and resilience. Without that expenditure, the failing assets do not repair themselves.

That is a legitimate case. It is also why executive pay cannot be treated as a private matter between a board and its labour-market consultants. Customers are being asked to pay more now for improvements arriving over years. The leadership team is being paid now to deliver those improvements. The test is not whether its salaries resemble those at Thames, Severn Trent or United Utilities. The test is whether the service changes fast enough to justify the money extracted from households that cannot shop around for another sewerage provider.

Southern Water’s remuneration policy now targets executive base pay at roughly the 60th percentile of nine water-and-wastewater companies. The committee considered the median too low to attract and retain the necessary talent, but said upper-quartile fixed pay was not warranted given performance, regulation and stakeholder expectations.

That sounds restrained until the circularity becomes visible. Water companies benchmark against other water companies. One company raises pay to remain competitive; the comparator moves; another reviews its position. The market rate becomes whatever the same small group of regulated monopolies has agreed to pay.

The next reward has already been designed

Southern Water has replaced the old two-year scheme with a new LTIP running from 2025 to 2030. The maximum opportunity is 150% of salary for each year of the plan. Forty per cent of the assessment is environmental, 40% financial resilience, 10% customer performance and 10% workplace culture. The first element will not be paid until July 2028.

Unlike the historic award that survived the first prohibition, the new LTIP is explicitly subject to Ofwat’s rule. Where the prohibition is triggered, the award is reduced for the affected year. Southern Water says the scheme is shareholder-funded and cannot be recovered from customers.

That is an important tightening, not evidence of a fresh evasion. It aligns the long-term plan with the statutory rule and introduces deferral, malus and clawback provisions. The committee can reduce or recover awards after misconduct, regulatory censure, serious governance failure or material misstatement.

Yet the scale remains considerable. At current salaries, 150% represents a theoretical annual maximum of about £804,000 for the chief executive and £622,000 for the finance director before future salary changes. Over several years, even pro-rated awards can become very large. The public will need to watch the actual targets, not merely the scheme’s environmental labels.

For 2026/27, Southern Water has also removed the single EPA-star measure from the annual bonus scorecard, saying the Environment Agency has changed its methodology. It has replaced it with operational measures covering pollution, internal and external flooding, bathing-water quality and storm-overflow reduction. The statutory prohibition still sits above the scorecard.

Again, that is not proof of a loophole. But it demonstrates how flexible the machinery is beneath a supposedly simple ban. Measures can be changed, weights shifted, payments deferred and rewards split between salary, benefits, annual plans and long-term plans. Public scrutiny must follow the money across all of them.

A useful ban, but not the end of the argument

The Guardian is right to question an industry whose total executive pay rose for a second year while bills and public anger climbed with it. It is also right to record that Southern Water’s reported executive pay fell.

Both things can be true.

Southern Water’s current annual bonuses were genuinely stopped. Its latest total packages genuinely fell. The company has made measurable progress on leakage, supply interruptions, external flooding and some bathing waters. Shareholders injected substantial new equity and received no external dividend.

It is equally true that the previous year’s blocked annual bonuses sat beside a £1.225 million historic LTIP award; fixed pay and benefits have continued to rise; the company achieved only 36% of its performance commitments; and pollution, customer service, internal flooding and wastewater compliance remain far from anything that could sensibly be called transformed.

The bonus ban is therefore neither useless nor sufficient. It creates a hard consequence when a company crosses the specified line. What it cannot do by itself is decide what fair executive pay looks like in an essential monopoly, prevent salary benchmarking from ratcheting upwards, or guarantee that a reward system gives the greatest weight to the failures that matter most outside the boardroom.

Southern Water’s own chair described the task as balancing reward for complex leadership with penalties for poor performance. The accounts show how hard the company has worked on that balance.

They also show which side still has the heavier thumb.

For customers, the final calculation is simpler. The bill has risen. The debt has risen. The investment has risen. Some services have improved sharply. Pollution and complaints remain high. The bonuses were stopped, but the reward machinery is waiting for the next year in which the prohibition does not apply.

The public does not live “in the round”, the phrase remuneration committees use when weighing one measure against another.

It lives at the end of the pipe.
