Private equity firm EQT acquired a 42 percent stake in Yorkshire Water last month at a significant discount, reflecting increased caution in the UK water sector amid financial and regulatory challenges. The transaction valued Yorkshire Water’s parent company, Kelda Holdings, at approximately £9.4 billion, which is about 90 percent of the company’s regulatory capital value, according to sources familiar with the deal. This figure marks a notable decline compared to historical valuations in the industry.

The pricing comes in the wake of ongoing turmoil within the UK water sector, including the financial difficulties faced by Thames Water and heightened regulatory scrutiny over environmental concerns such as sewage pollution. These factors have contributed to a broader reassessment of water utilities’ valuations.

Yorkshire Water, serving approximately 5.7 million customers across northern England, is currently navigating regulatory pressure from Ofwat. The water services regulator has required the company to repay a £600 million loan amid concerns about its financial sustainability. As part of the recent acquisition, EQT has committed to contributing toward the repayment of this loan.

Historically, water companies in the UK have traded at premiums above their regulatory capital values—the asset base on which they are permitted to earn returns through customer billing. Data from Ofwat reveals that listed water companies were valued about 10 percent above their regulatory capital values over the 30 years leading up to 2024. More recently, sales of stakes in water companies between 2017 and 2024 have averaged a 36 percent premium, according to court documents from a Thames Water case.

Despite these headwinds, EQT’s investment signals ongoing interest in the water sector, contrasting with earlier remarks from major Thames Water shareholders who characterized the company as “uninvestable.” Sources indicate that EQT’s valuation approach accounted for the sector’s challenges, including a prolonged period of under-investment, while also factoring in regulatory decisions permitting some companies to increase customer bills by over 50 percent between 2025 and 2030.

Representatives from EQT, Deutsche Bank, which previously managed the stake, and Yorkshire Water declined to comment on the terms of the transaction. The deal underscores the cautious optimism among investors as the sector adapts to evolving financial and regulatory environments.
