With 2025 delivering the UK’s warmest summer on record, followed by 50 consecutive days of rainfall, the country has experienced a clear example of 'weather whiplash'.
These extremes are placing growing pressure on already stretched water systems. Dry springs, falling reservoir levels and rising demand mean that for organisations operating across the UK, weather whiplash and drought are increasingly becoming operational risks that affect sites, processes and costs.
With some parts of the UK experiencing one of the direst Aprils on record**, it is becoming increasingly important for organisations to understand what this means for their operations and what they can do about it.
Weather whiplash creates higher risk
As climate patterns continue to change across the UK, heatwaves are becoming more frequent, rainfall more unpredictable and prolonged dry periods more likely. Together, these factors create a perfect storm: higher demand for water at the same time as supply is under pressure.
The impacts for organisations can be wide-ranging, from operational disruption and rising costs to reputational risk. Customers and communities are also paying closer attention, expecting responsible water stewardship and meaningful action, not just reactive communications when restrictions are announced.
How to stay ahead
Resilience doesn’t start when restrictions are announced or emergency measures are introduced. It’s built much earlier, by understanding how, where and why water is used across your operations, and identifying opportunities to use it more efficiently.
By embedding water efficiency into everyday decision making, whether that’s investing in smarter data, improving visibility of usage, identifying leaks earlier or building a culture that values water as a finite resource, organisations can significantly strengthen their resilience to disruption.
Taking time now to review how your organisation uses water can help reduce exposure before risks escalate. Practical steps include:
- Reviewing water use and exposure to drought risk through a water audit
- Challenging whether existing plans are fit for hotter, drier conditions, and
- Embedding efficiency, data and collaboration into day‑to‑day operations.
For many organisations, drought also highlights gaps in long-term resilience planning. Water underpins multiple parts of an operation, from production and hygiene to energy use, yet its availability and cost are still often treated as low risk.
Understanding water dependency, stress‑testing operations against prolonged dry periods, and aligning drought planning with wider sustainability and resilience strategies are becoming essential steps in managing future risk and staying operationally resilient in a changing climate.
Small changes, big difference
When it comes to water use, small changes can deliver meaningful results. Our top tips for business water efficiency make it easier to reduce water use and cut costs, while our My Business Stream platform gives you greater visibility and control over your account and consumption.
