England’s Water Crisis Wasn’t Supposed to Happen

For a country often synonymous with drizzle and overcast skies, England is an unlikely candidate for water stress. Yet by late spring, some reservoir levels had slipped below average (For example, United Utilities was at 63%). The remarkable season unfolded month by month, beginning with a record-breaking sunny March that set the tone, with above-average temperatures and significantly reduced rainfall. April 2025 continued the trend as the UK's sunniest April on record, maintaining the warm and dry pattern. Recent weather has offered some relief. Whilst this is a result of a change in weather, it is most likely driven by climate change. But that’s only part of the story.

The real crisis sits at the intersection of a warming climate and a decades-old failure to adapt to the potential impacts. The UK’s water infrastructure was never built with today’s weather variability in mind. It reflects a different era in which rainfall could be taken for granted and storage was designed around predictability rather than extremes. Also, over time, regulatory oversight has failed to keep pace with the growing risk. Arguably, a key element of this situation was the 1989 privatization of the water & sewage. The new model saw private ownership of the 10 regional water authorities with oversight from a regulator – Ofwat (Office of Water Regulation) - a non-ministerial government department.

Instead of planning for drought cycles or long-term water stress, attention remained focused on investor returns, short-term efficiency targets, and the patching of aging systems just enough to stay operational. Whilst the discrete impacts of climate change may not be predictable, the likelihood of negative impacts has been known for some time.

That institutional inertia is being revealed by reality. While climate change alters the physical environment, shifting precipitation patterns, increasing evaporation, and disrupting natural water cycles, policy responses have failed to effectively address it. Mitigation, particularly in emissions reduction and net-zero commitments, has dominated headlines and budgets. Adaptation, on the other hand, is seen as politically unglamorous, harder to measure, and easier to delay. As a result, the physical impacts of climate change are hitting infrastructure that wasn’t prepared to absorb them.

The regulatory failures are no longer abstract. Thames Water plc, which is responsible for the supply of water & sewage for 16 million people, came dangerously close to collapse earlier this year. At the same time, the company continued to discharge sewage into rivers and seas, while senior executives collected bonuses. These aren’t isolated incidents; they’re symptoms of a system that prioritized ‘financial stability’ on paper over resilience in practice. Ofwat, the body tasked with oversight & regulation, has only recently begun to enforce penalties and block bonus payments in response to public outcry. This move signals a reaction, not readiness. Arguably, the sewage discharge incidents are not directly attributable to climate change, but the are attributable to poor management by the water companies.

What’s was missing was a coherent, forward-facing adaptation strategy. Water management in the UK, and elsewhere, often rests on assumptions that no longer hold. Systems are built to deliver water efficiently, but not necessarily to store it through extended dry periods. Maintenance is reactive. Long-term investment depends on regulatory pressure rather than shared national planning, and too often, when the conversation does turn to water, it centers on consumer behaviour rather than systemic reform.

This situation isn’t unique to Britain. Around the world, the same pattern plays out: a growing mismatch between climate change impacts and the institutions meant to manage its effects. But the UK’s case is especially telling because it combines environmental stress with poor governance. It shows how even in developed countries, with the resources to act, water crises can emerge not only from scarcity, but from a failure to take scarcity seriously in time. Just imagine the impact on underdeveloped countries.

Adaptation should not now be seen as a secondary issue. It is clear that the chances of meeting many climate change mitigation targets are less likely. Around the world, we are experiencing the impacts of climate change, and we need to learn how to live with those impacts; we need to adapt regardless of what mitigation actions are successful.

It’s the policy groundwork, systems and infrastructure that determines how societies function under pressure, which was clearly demonstrated during the Covid pandemic. We need to consider how well infrastructure systems (water and energy) can handle stress without breaking, how equitably risk is distributed, and how credible institutions remain when the weather turns against them. Is it too late for the UK? Well, it will need the political will, investment and time to resolve the issues. We watch with interest.

Benjamin Franklin is popularly credited with saying, "When the well's dry, we know the worth of water." The problem is, when the well is dry, it may be too late to act. The situation in the UK can be seen as a call to action.
