If Thames Water cannot secure a private rescue, who bears the cost of keeping water services running and fixing its environmental failures?

Advocate A’s weakest point is the implied separation between “past financial engineering” and the costs customers or taxpayers must bear. It is right that equity should be impaired first and that creditors should not be made whole for mispricing Thames Water’s leverage. But that does not answer the core question: who funds legally required water and wastewater service while a monopoly with Victorian-era assets, pollution obligations and no ordinary competitive exit route is unable to raise capital? A’s framing treats special administration as if it mostly reallocates past losses to creditors; in practice it is a continuity mechanism that may require public funding and then a recovery mechanism if sale or restructuring proceeds are insufficient. The government’s own policy statement says a water SAR would prevent disruption to services, but also that government funding may be needed and that new powers allow licence modifications to recover any unrecovered shortfall. That is customer or state exposure, not merely creditor punishment. (gov.uk)

The first counter-evidence is Ofwat’s own PR24 settlement. For Thames alone, Ofwat allowed £20.5 billion of expenditure for 2025-30 and £16.4 billion to be collected from household and business bills over that period; average household bills rise by £152 before inflation by 2029-30. Ofwat explicitly says investment costs are recovered from bills over the long term and companies must first finance expenditure with debt and equity. That means customers are already a central funding source for fixing assets and environmental compliance, irrespective of whether investors take haircuts. A can object to customers paying for bad leverage, but cannot avoid customers paying the regulated asset base cost of sewage, leakage and resilience work. (ofwat.gov.uk)

Second, the latest rejected creditor proposal undercuts the idea that the live policy choice is “protect creditors versus protect the public.” Reuters reported that the creditor plan would inject £3.35 billion of new cash, add a £6.55 billion debt facility and write off £9.4 billion of debt, while the government objected and said it was ready for any outcome. That proposal may still have been too generous or too costly in fees, but it was not full investor protection; it was an attempt to supply capital that the state would otherwise have to replace under SAR. (lse.co.uk)

Third, this is not just one company’s misconduct. The Independent Water Commission described “deep-rooted, systemic and interlocking failures” across government strategy, regulation, environmental protection and company ownership. Ofwat’s sector PR24 determinations support £104 billion of water-company spending over 2025-30, a scale that depends on continuing access to private finance. Excessively punitive creditor losses at the largest water monopoly would not merely discipline Thames; they would likely raise perceived regulatory and political risk across the sector, making that investment harder or more expensive. (gov.uk)

A’s rebuttal concedes the decisive ground: Thames customers must pay a substantial share of future investment through bills, and taxpayers may have to provide bridge funding in special administration, with unrecovered losses recoverable from consumers through licence changes. That concession implies the debate is not “investors pay versus the public pays.” It is how much public-facing cost is unavoidable once an essential monopoly cannot finance legally required service and environmental obligations on ordinary market terms. A’s answer—separate “future service” from “historic leverage”—is normatively attractive but operationally incomplete because the regulated asset base model links future service to financeability. Ofwat says Thames’s investment costs are recovered from bills over the long term, while companies must first finance spending by attracting debt and equity; for Thames, the 2025-30 determination allows £16.4 billion of bill recovery and £20.5 billion of expenditure, with average household bills rising £152 before inflation by 2029-30. (ofwat.gov.uk)

The weakness is that A never specifies the boundary between legitimate creditor haircuts and excessive impairment that damages sector-wide financeability. Saying “creditors absorb the balance-sheet failure” is not a financing plan if Thames needs new money immediately and if the wider sector is expected to deliver the second-largest infrastructure programme in the UK. The Independent Water Commission’s final-report release says water companies will spend £104 billion over five years and that fragmented regulation has undermined a whole-firm view; it also says a more stable regulatory regime would improve investor confidence. That supports my central claim: the crisis is systemic, and loss allocation must preserve access to capital for the whole sector, not merely punish Thames’s past structure. (gov.uk)

A also understates the practical fiscal risk of special administration. The Water (Special Measures) Act 2025 explanatory notes state that the Secretary of State may modify licence conditions to make good shortfalls after financial assistance to a company in special administration, and those modifications can require a water company to raise money from consumers; the power can apply to the failed company or any other English water company. That is not just temporary liquidity: it is a statutory mechanism for socialising residual rescue losses if restructuring or sale proceeds are insufficient. (legislation.gov.uk)

Finally, the live creditor proposal was not “full investor protection.” Reporting on the June 2026 dispute said London & Valley Water would inject £3.35 billion of new equity and up to £6.55 billion of new debt, while the government still preferred a market solution and the company was running out of cash. A is right to scrutinise fees and adviser payments, but rejecting private capital without a detailed cheaper alternative means the state must supply or backstop equivalent continuity funding. (itv.com) A’s position therefore handles moral hazard better than it handles the core issue: maintaining water service and funding upgrades when the private finance channel may fail.

A’s strongest argument is that customers should not be asked to pay twice: once through Ofwat-approved bills for forward-looking investment, and again through higher charges, penalty waivers, or public guarantees that preserve historic creditor value from an overleveraged structure. A is also right that a special administration regime exists precisely to maintain continuity while restructuring a failing essential utility, so service continuity does not logically require making lenders whole.

My position remains stronger because A’s distinction between “future service costs” and “historic financing costs” is clean in principle but unstable in practice for a regulated asset business that must finance enormous investment before it is recovered from bills. Ofwat’s Thames PR24 determination allows £20.5 billion of expenditure in 2025-30, with £16.4 billion to be collected through bills and average household bills rising by £152 before inflation by 2029-30. That means customers are not just passive victims of a bailout decision; they are the statutory revenue base for the works needed to reduce leakage, sewage spills, asset failures, and environmental non-compliance. If private debt and equity cannot be raised on acceptable terms, the missing financing has to come from somewhere: government liquidity, public ownership, bill-funded recovery mechanisms, or delayed works that impose costs on the environment.

A’s model also underweights the sector-wide financeability constraint. The Independent Water Commission described deep, interlocking failures across government strategy, regulation, environmental protection, and ownership, and the government’s water reform material points to a £104 billion investment programme for the sector over 2025-30. In that context, Thames is not merely a morality play about one bad balance sheet. A very severe creditor outcome might be justified if it is transparently tied to insolvency value and misconduct, but if investors perceive the outcome as politically discretionary, the cost of capital for other water companies could rise. Even a modest sector-wide increase in financing costs would eventually be borne by customers or would reduce deliverable investment.

The special-administration backstop strengthens, rather than weakens, my conclusion. The Water (Special Measures) Act 2025 explanatory notes make clear that unrecovered financial-assistance shortfalls can be recovered through licence modifications, including mechanisms that raise money from consumers. That is evidence that Parliament anticipated residual socialisation of losses if restructuring proceeds are insufficient. The June 2026 creditor proposal may have been imperfect, especially if it required penalty waivers or excessive fees, but it reportedly offered £3.35 billion of new equity and up to £6.55 billion of new debt when Thames was close to collapse. Rejecting such private capital without a demonstrably cheaper SAR alternative risks converting a creditor haircut principle into a public financing obligation.

So the strongest rule is not “protect creditors”; it is “minimise total public-facing cost while preserving financeability and environmental delivery.” Equity should be wiped out and creditors should take real losses, but customers and the state will still bear a significant share because the true cost is keeping a failing monopoly operating while funding decades of underpriced infrastructure and environmental obligations.
