England’s reservoirs continue to feel drought strain after sixth dry month of 2026

England’s reservoirs are now notably or exceptionally low, with most holding less than half their usual capacity despite the Environment Agency’s expectation of 74.3% fullness at this time of year. Ardingly in West Sussex and Wimbleball in Somerset are particularly affected, standing at just 23% and 21% full respectively. The government has prioritised water security, with the Prime Minister and Environment Secretary emphasising its importance, while coordinating sector-wide responses through weekly National Drought Group meetings. A strengthened Water Bill is being introduced to reform the industry, including plans for nine new major reservoirs to secure long-term supplies.

September marked the sixth consecutive month of below-average rainfall in England, averaging 65% of typical levels, though regional disparities persist. The east and south east recorded the lowest rainfall at 52% and 57% respectively, while central England saw 59% and the south west 69%. Cooler temperatures have slightly reduced demand, but usage remains higher than expected for this period, continuing to strain reservoirs and public supplies. The Environment Agency has warned that 120% of average rainfall over the next seven months would be required to fully alleviate drought conditions by spring.

The government has announced measures to ease pressure on water resources, including the potential for non-essential use bans to prioritise household supplies. South East Water is set to apply for such a ban today, while the Environment Agency is expediting drought permit applications to allow water companies to reduce river water contributions. These steps aim to protect public supplies while balancing environmental and wildlife needs, with enhanced monitoring and stricter checks on water abstraction already in place.

Additional support for farmers has been introduced, including changes to abstraction licence rules allowing earlier filling of on-farm storage reservoirs from yesterday instead of November 1st. A £65 million funding boost has also been allocated to assist farmers, though these measures exclude principal salmon rivers and areas under S57 restrictions to protect fish stocks and the environment. The reforms follow the government’s commitment to long-term water security amid increasing climate-driven extremes.
