From October 9th, exemptions for vulnerable customers will end as record dry conditions push reservoir levels to crisis point.
South East Water is widening its hosepipe restrictions to encompass every customer, including those previously shielded from such measures, as the region grapples with its most severe water shortage in decades. The decision comes on the back of a devastatingly dry September, which has left key reservoirs critically low and intensified the ongoing drought gripping parts of southern England.
Expanding Restrictions Beyond Essential Use
The water supplier, which serves approximately 2.4 million homes and businesses across southeast England, initially rolled out a temporary hosepipe ban earlier this summer for the majority of its customers. However, starting from October 9th, all remaining exemptions will be lifted—meaning individuals registered under the company’s vulnerable customer scheme will no longer be exempt from the ban.
This move marks a significant escalation in response to worsening environmental conditions. While essential exemptions for health and safety reasons, as well as animal welfare, will remain in place, other allowances—such as those granted to domestic window cleaners—are being withdrawn.
In addition, South East Water has formally requested the government approve a Non-Essential Use Ban (NEUB), a more stringent measure that would extend restrictions beyond household usage to include commercial operations like construction site dust suppression, car washdowns, lawn irrigation, and pool filling.
Dry Conditions Compound Record-Breaking Heat
The expansion of restrictions follows a particularly arid September, which saw rainfall levels drop to just 57% of the long-term average in the southeast—one of the driest regions nationally. This comes after an unprecedented summer characterised by prolonged dry spells and consecutive heatwaves, leaving soil parched and river flows diminished.
Nationally, last month marked the sixth consecutive month of below-average precipitation, with England receiving only 65% of typical September rainfall. For South East Water, the situation has become dire. Its Ardingly Reservoir in West Sussex—a vital source serving over 228,000 customers near Haywards Heath—is now just 23% full, starkly contrasting with the national average reservoir capacity of nearly 74% at this time of year.
These alarming figures have triggered the next stage of the company’s statutory drought plan, compelling further action to safeguard both public water supply and aquatic ecosystems.
Company Warns of Long-Term Environmental Impact
Nick Price, Head of Water Resources at South East Water, acknowledged the gravity of the current situation. “The prolonged warm and dry weather experienced during spring and summer has left the ground extremely parched, significantly reducing flows in local streams and rivers,” he explained.
He continued: “Without substantial rainfall soon, we risk continued depletion of our underground aquifers and surface waters—the very sources that sustain our communities.”
Mr Price recognised that increased restrictions could cause concern among customers but stressed that protecting long-term resilience remains paramount. “Our focus is on implementing sustainable practices through our long-term business strategy, ensuring a stable water supply for today and future generations,” he said.
The company also expressed gratitude towards customers who have already begun reducing their water consumption in light of the ongoing crisis.
Drought Permit Granted Amid Falling Reservoir Levels
In related developments, South East Water was granted a drought permit by the Environment Agency last week, allowing it to reduce environmental releases from Ardingly Reservoir into Shell Brook—a tributary of the River Ouse. Additionally, the minimum flow requirement at Barcombe Mills on the River Ouse has been adjusted to reflect current realities.
While necessary to preserve drinking water reserves, these changes may have downstream ecological consequences, underscoring the complex balance between human needs and environmental protection during periods of extreme drought.
Why it Matters
The widening hosepipe ban reflects a growing national challenge as climate change intensifies the frequency and severity of droughts across the UK. With reservoirs running dangerously low and groundwater levels declining, water companies are being forced into increasingly restrictive measures—even affecting society’s most vulnerable members. As public awareness grows around water security, this case highlights the urgent need for investment in infrastructure, conservation strategies, and policy reform to manage finite resources responsibly in an era of rising temperatures and unpredictable weather patterns.
