England’s reservoirs continue to feel drought strain after sixth dry month of 2026
Summary
The Environment Agency says England’s reservoirs remain under significant drought pressure after a sixth month of below-average rainfall in 2026, with many reservoirs now classed as notably or exceptionally low. Southern and central England are most affected, and the government is working with water companies on drought measures, including restrictions and supply protection steps.
Why it matters
Prolonged drought can affect water availability for occupied homes, development sites and building operations, and may increase the likelihood of local restrictions or supply disruption. Surveyors should be aware of the wider environmental context when advising on property risk, services resilience and regional market conditions.
Key points
- Most of England’s reservoirs are now notably or exceptionally low.
- Ardingly and Wimbleball reservoirs are reported at 23% and 21% capacity.
- September rainfall averaged 65% of normal across England, with the east and south east worst affected.
- The Environment Agency is processing drought permits and increasing monitoring of water company actions.
- South East Water is expected to apply for a non-essential use ban.
