There has been an atmosphere of rather resolute pessimism in the water industry lately, with the biggest company struggling under the weight of its own catastrophic mistakes and with both residential and business customers expected to literally pay the price through increased rates.
However, in the spirit of the festive season in the run-up to Christmas, a recent report by Ofwat may provide some welcome relief, as it reveals that bill increases may not increase as starkly as some of the grimmer estimations have predicted.
Are prices set to decrease? What does this mean for your water bills? And does this positive for customers potentially have a sting in the tail for the biggest water company in England?
Why Are Water Companies Receiving Less Money?
Part of why the news surrounding water prices has changed so drastically and so dramatically has much to do with the ways in which Ofwat calculates and publishes its determinations for revenue and regulatory capital value (RCV), both of which affect how much water companies are allowed to charge.
The process is somewhat complex, but one of the core elements of the pricing structure is financial performance. In 2024, the provisional price increases were determined by expected revenue, capital spending, investment and overall performance.
When the final figures were released in the summer of 2025, Ofwat found that water companies were actually doing significantly better than the estimates suggested and are set to reduce the amount of revenue water companies can take from customers through bills.
The detailed figures are available via Ofwat, but the main takeaway is that water companies as a whole will receive £309m less from customers, which, assuming there are roughly 30m dwellings in the UK, means that people will save £10.30 on average on their water bills between 2025 and 2030.
How Does Ofwat Determine Water Prices?
- Ofwat made an initial projection in 2024 based on expected financial performance.
- This determination is altered by the actual financial figures released to Ofwat in Summer 2025.
- Ofwat revised its figures, which affect how much water companies can charge.
Does This Affect Crisis Talks At Thames Water?
Over half of this revenue reduction comes from Thames Water, which saw a 40 per cent rise in its revenue thanks to significant bill increases but will therefore lose £187m in revenue relative to expectations.
This is one of many factors that have caused Thames Water to state their “material uncertainty” that they can continue as a business in even the near term, which would trigger a special administration regime.
This would force the government to assume temporary ownership and control of Thames Water, work to clear its debts and restructure before selling it again once it is a going concern.
At present, Thames Water are in the process of “crisis talks” that, according to a source reported by The Guardian, are taking longer than expected owing to the complexity of the situation.
These talks, which primarily involve a leading consortium of creditors, have been ongoing since hedge fund KKR walked away from buying Thames Water due to the threat of regulatory sanctions.
Why Are There Crisis Talks At Thames Water?
- Thames Water has over £17.6bn of debt and is at serious risk of collapse.
- Following the collapse of a purchase bid by KKR, a consortium of creditors has offered to take over the struggling firm.
- The terms have for months been unacceptable, and include 15 years of regulatory leniency and selective cuts to certain types of debt, leading to a revolt by other shareholders.
- Alternative proposals have been made, and the complexity of the situation risks time running out on a market-led solution.
Is A Market-Led Solution Still Possible?
The UK government is keen to avoid an SAR at all costs, which it has described as “nationalisation” and has made a claim disputed by Left Foot Forward that the total cost would be £100bn via a report allegedly funded by four leading water companies.
With crisis talks having remained at an impasse for months due to inadequate writedowns of debt, unclear details on how money will be spent and a request for leniency on fines that has been seen as unacceptable by the UK government in the past, it remains to be seen if refinancing or a takeover is possible.
The key point in its favour is the desire for a “market-led” solution, but unless the government and Ofwat cave on fundamental objections, this appears to be less likely with each passing day.
Key Takeaways
- Water companies will receive £309m less than expected.
- Ofwat believes water companies will do better than expected.
- Crisis talks at Thames Water have been delayed, which could further complicate any potential takeover.
- Time is rapidly running out before a special administration becomes the only option.
