If Thames, which has borrowings of nearly £19bn, is put into special administration, it is estimated that as much as £5bn of financial support would be needed to keep customers connected.
The utility giant is currently reliant on massive investment from its shareholders, which include Canadian pensions business Omers and the China Investment Corporation.
However, cash is dependent on Thames being able to hike household bills, a proposal that could be blocked by Ofwat if the supplier continues to perform poorly against sewage and leakage targets.
So, investment is needed to reduce leaks and sewage. OK.
Investment must be raised from investors.
To gain investors price must rise.
Prices cannot rise until leaks and sewage are reduced.
This isn’t a problem of private ownership. This is a regulatory problem. OfWat are being twats that is. For, of course, the same problem would occur under any ownership. Prices have to rise to fund investment.
I’m not sure that this would have happened in a better regulated market. Thames was majority owned by a series of “investors” who stripped the company of cash and left it with huge debts without sufficient investment in the infrastructure. London of course having the oldest main sewers in the country. The Victorians knew what they were doing, but the walls crumble over time and the population now all has indoor plumbing as do office blocks containing thousands of people.
This is a failure if orivatisation. But it is a failure of the regulator’s making.
A symptom of the “someone else must pay”mindset prevalent in the U.K.
After all, actually earning your living by providing what someone else wants is old fashioned, now we sell advertising to each other via ticktok, YouTube and suchlike.
Ofwat used outmoded methodology to set too low an allowed rate of return on capital, which in turn meant that prices to consumers were too low. When the water cos analysed the situation using their higher market rates of return, they concluded that the best policy was to strip out the cost generated by existing assets and underinvest in new ones.

Investing in Thames Water: a lesson in infrastructure valuation for investors
Thames Water, the UK’s largest water and wastewater utility, seems to be the epitome of a stable and predictable asset. Yet, in December 2023, the value of this investment was impaired by almost 30%. This unexpected loss of approximately GBP1.5 billion had a great impact on many investors, including UK, Japanese and Canadian pension plans. [update: in the latest accounts of one of its main shareholders, Thames was impaired by 60%, twice as much as the previous impairment, bringing the loss to more than GBP3 billion].
In their EDHEC Infrastructure & Private Assets Research Institute paper “Low Tide – Benchmarking risks in Infrastructure Investments: What the data showed about Thames Water” (1), authors Frédéric Blanc-Brude, Abhishek Gupta and Tim Whittaker explored what investors in Thames Water (and its holding company) could have learned about the level of risk of their investment, had they compared its characteristics to market and peer group data.
The benefits of benchmarking in investing
In their paper, the authors showed that a comparative analysis, also called benchmarking, would have revealed that Thames Water was not a stable investment, but instead a high-risk, low-return one.
As a matter of fact, the asset must have been mispriced for several years leading up to the staggering loss. According to the authors, its value had actually been decreasing for years (2).
Their research shows that benchmarking the key characteristics of Thames Water would have provided a much better understanding of its risk profile. How? By using a comparable set of what a typical company with the same attributes as Thames Water is like in terms of risk factor exposure, duration and likelihood of dividend payouts. This would have demonstrated the fact that the firm is likely to have lost between 30 and 50% of its value over the past decade, which it did, eventually. (3)
Without this analysis, investors failed to see the big picture. They actually fell prey to a form of thinking that is still very common in infrastructure investment, consisting of looking narrowly at the asset, but not at the market or at peers.
The 3 red flags that should have raised concerns among investors
Here are the three red flags that investors should have considered long before the impairment of Thames Water in December 2022:
Red flag #1: Extremely low regulated weighted cost of capital
The company had an extremely low regulatory weighted average cost of capital (WACC), which is the average rate that a business pays to finance its assets. That could only push it to take on too much risk to achieve the level of returns required by the market.
Reg flag #2: A tendency to lever up to pay more dividends
As a response, investors in Thames Water created a structure to extract the maximum amount of cash as fast as possible. This dividend policy, inconsistent with the economic performance of the asset, created significant debt levels and the exhaustion of the balance sheet.
Red flag #3: High systematic risk factors exposures
The company’s exposure to key risk factors identified in EDHEC research as driving returns, had been high and rising for a significant period. This could only lead to an increasingly higher market risk premium, that is to say an additional return investors expect from holding a risky market portfolio instead of risk-free assets. Therefore, a likely loss in value that was not recognized for years.
Had they been identified early on, these red flags could have led to a revaluation of the asset.
Lessons learned from this specific case
So what lessons can be learned from the Thames Water brutal impairment?
First, investors should have questioned the reported valuation of the asset. This specific case underscores the importance of a comparative analysis in assessing asset valuation and risk. Investors in Thames Water could have benefited from a comparative approach, rather than narrowing their focus.
For most investors, owning the water utility of the capital of a G7 country would be the ideal investment. It would be easy to think that this asset would pay regular and predictable dividends to shareholders, and that its valuation should not be too volatile. But, as we have seen, this was not the case with Thames Water. On the contrary, when compared with its peers, the water utility showed some significant risks that were not accounted for when assessing the asset.
The authors also showed that a flawed methodology had been used for estimating the cost of equity capital, which is the return a company must provide to its shareholders in exchange for their investment. They emphasized that this mispricing of Thames Water’s cost of capital by the regulator had created unhealthy incentives for the management to maximize short term returns, leadind to excessive risk-taking and the destruction of shareholder value (4).
As a result, the valuation of the asset by its shareholder was held steady or increased until March 2022, before dramatically decreasing. A reminder that the value of such assets can be very volatile.
All in all, Thames Water provides a good case study for investors, reminding them to always take a comparative view of their assets. In this case, this would have helped to identify the red flags sooner and provided a better assessment of the risks involved in investing.

I find it almost inconceivable that an arm of government (Ofwat) could have been responsible for this mess with Thames Water.
They run our beloved NHS (which is a wonder of the world), secure our borders, defend the realm, and maintain tight fiscal policy to stop us going bust.
Presumably if it turns out that Ofwat were deficient, it’d be some sort of aberration and not indicative of the performance of the people in charge of the levers of power!
It sounds more like Oftwat to me.
“I’m not sure that this would have happened in a better regulated market.”
That really does sound like “It has failed under this regulatory system, so more regulation please”.
