How could the low water levels at Ardingly affect the Environment Agency?
The Environment Agency faces increased pressure to ensure water resilience amid severe drought. The Environment Agency expects reservoir storage to be around 75% at this time of year, meaning the current levels fall significantly below regulatory expectations. This situation reinforces the agency's mandate to ensure long-term water resilience against climate change and population growth, requiring continued focus on securing current supplies and planning for future shortages.

How it reaches Environment Agency
-
Caroline Allan observed low water levels at Ardingly on October 30, 2026. The Ardingly reservoir, which serves approximately 95,000 properties near Haywards Heath and Uckfield, is currently 19% full. This observation follows the declaration of severe drought in several southern English counties, including East Sussex and West Sussex.
The full event1independent outlet -
The Environment Agency expects reservoir storage to be about 75% at this time of year. The current 19% level at Ardingly means supplies are critically low compared to the agency's environmental expectations. The ongoing drought and critically low supplies reinforce the need for the Environment Agency to focus on climate resilience. Water companies are required to take every available measure to secure current supplies while planning for future challenges.

Why it matters
The low water levels at Ardingly represent a significant failure to meet expected environmental standards, putting pressure on the Environment Agency's regulatory function. The agency is tasked with ensuring the resilience of water supplies against climate change, and the current situation demonstrates a critical gap between expected and actual reservoir capacity.
This issue is part of a wider national concern, as almost three-quarters of England and large parts of Wales are still in drought or severe drought. The government's national drought group has been informed that recent rain has not changed the drought outlook, highlighting the systemic nature of the water scarcity problem across the UK.
What we don't know yet
- What specific measures will the Environment Agency mandate to address the shortfall between expected and actual reservoir levels?
- How will the Environment Agency assess the long-term impact of increasing water demand from new housing and datacentres?
