TL;DR
Thames Water has introduced a hosepipe ban across its service area due to ongoing drought conditions. The restriction aims to conserve water as reservoir levels remain critically low. The ban is effective immediately and will last until further notice.
Thames Water has implemented a hosepipe ban across its service area starting immediately, citing ongoing drought conditions and critically low reservoir levels. The restriction affects millions of customers and aims to conserve water amid persistent dry weather. This is the first such ban in the region this year, and officials warn it could last until conditions improve.
Thames Water announced the hosepipe ban on March 26, 2026, citing a combination of prolonged dry weather and reservoir levels dropping below safety thresholds. The ban prohibits the use of hosepipes for watering gardens, washing cars, and filling ponds or pools. The restriction applies to residential customers in Greater London, Berkshire, Surrey, and parts of Hertfordshire.
According to Thames Water, reservoir levels have fallen to approximately 55% capacity, the lowest in over a decade. The company has urged customers to reduce water use voluntarily and has increased public awareness campaigns. Penalties for non-compliance could include fines or other enforcement actions.
Local authorities and environmental agencies have supported the move, emphasizing the importance of water conservation during the drought. The ban is expected to remain in effect until rainfall improves reservoir levels significantly, though no specific end date has been set.
Impacts of the Hosepipe Ban on Regional Water Supply
This ban highlights the severity of the ongoing drought in southeastern England, with potential long-term impacts on water availability. It underscores the importance of water conservation for residents and authorities, as prolonged dry conditions threaten supply stability. The restriction also signals increasing pressure on water infrastructure and the need for sustainable management strategies amid climate change challenges.

Recent Drought Conditions and Water Supply Challenges
England has experienced below-average rainfall over the past six months, leading to critically low reservoir levels in the Thames Water catchment area. This situation follows a series of dry winters and a lack of significant rainfall in recent weeks. Thames Water and other regional suppliers have previously issued warnings about potential restrictions if conditions worsened.
In 2022 and 2023, similar water restrictions were implemented temporarily during peak summer months. This year’s drought has persisted longer, prompting the current hosepipe ban, which is the first in Thames Water’s service area since 2019.
Authorities have emphasized that climate change is contributing to more frequent and severe droughts, increasing the pressure on water resources and infrastructure.
“We are taking this step to protect our water supplies and ensure we can meet the needs of our customers during this challenging period.”
— Emma Clancy, Thames Water CEO
