A severe drought has been declared in six areas of England – Devon, Cornwall, Dorset, Somerset, East Sussex and West Sussex – after the UK experienced its hottest summer on record, with some reservoirs at critically low levels threatening public water supplies.

The Environment Agency has moved parts of southern and southwestern England into severe drought status. Two reservoirs, Ardingly and Wimbleball, are at 19% and 16% capacity respectively, far below the expected seasonal average of about 75%. Smaller reservoirs serving households in Devon and Cornwall are also under strain.

Despite the crisis, Environment Secretary Angela Eagle has yet to approve requests from three water companies – South East Water, South West Water and Southern Water – to extend non-essential use bans to businesses such as golf clubs, private schools and commercial car washes. Two of the companies operate in areas now in severe drought.

Speaking after a meeting of the national drought group, Eagle said: “This level of drought is something we have not experienced for decades, so this government is stepping up our support and planning. We are working closely with water companies to protect public supplies in the areas affected, and I’d continue to urge everyone to think about how they can use water wisely over the coming weeks.”

Water Minister Emma Hardy has instructed the Environment Agency to prioritise protecting public water supplies in affected areas, even where that means compromising environmental rules. The south-east and south-west of England recorded their driest April to September period in more than a century, fuelled by the climate crisis, according to officials.

Analysis

Why This Matters

  • The drought directly threatens public water supplies for hundreds of thousands of households in southern and southwestern England.
  • The government's decision to prioritise water supply over environmental protections signals a shift in policy under climate pressure.
  • Approval of business water restrictions could become a template for future drought management across the UK.

Background

England has experienced its hottest summer on record in 2026, compounding years of below-average rainfall. The six areas now in severe drought have seen the driest April-to-September period in more than a century. Reservoir levels are far below what the Environment Agency would expect at this time of year, with two major reservoirs under 20% capacity. The drought group meeting this week was convened to coordinate responses.

Key Perspectives

Water companies (South East Water, South West Water, Southern Water): Seek approval to ban non-essential water use by businesses to protect supplies for domestic customers. Their requests have not yet been granted. Environment Secretary Angela Eagle: Acknowledges the severity of the drought but has not immediately approved the business-use bans. She calls on water companies to improve their planning. Environmental groups and critics: Concerned that the instruction to prioritise public water supplies over environmental rules may harm rivers and ecosystems already stressed by low flows.

What to Watch

  • Whether the government approves the non-essential use bans requested by water companies in the coming days.
  • Reservoir levels in the affected areas over the next few weeks, especially if autumn rains fail to arrive.
  • Potential for the drought to expand to other regions as the dry spell continues.
