Severe Drought Declared Across Six English Regions as Water Supplies Threatened

By Grace Kim

A severe drought now covers six areas of England, with some reservoirs in the south-east and south-west at critically low levels and public water supplies under direct threat. The declaration, reported by The Guardian on October 15, 2026, marks an escalation in England's water crisis and pushes utilities toward emergency measures.

The affected regions are Devon, Cornwall, Dorset, Somerset, East Sussex and West Sussex. Together they span two of the country's most water-stressed corners — the south-west peninsula and the south coast. Urgent measures are now being taken to secure public supplies, according to the report.

What changes with a severe drought declaration?

The move from ordinary drought status to severe drought is not a label swap. It signals that the environment and water infrastructure have deteriorated to the point where public supply itself is at risk, not just agriculture or river ecosystems.

Two facts anchor the severity. First, some reservoirs in the south-east and south-west are at critically low levels. Second, water companies are calling for non-essential use bans on businesses — a step that directly targets commercial consumption rather than relying solely on household restrictions.

That second point matters for business readers. Non-essential use bans on companies would restrict water used for activities that regulators deem dispensable — typically cleaning, irrigation and similar operations — while protecting drinking supply. Utilities, in other words, are preparing to ration commercial water before the taps run dry for the public.

Which regions are affected?

The six areas under severe drought status:

• Devon
• Cornwall
• Dorset
• Somerset
• East Sussex
• West Sussex

Each is a coastal or near-coastal county in southern England, where reservoir catchments have failed to recover and storage has fallen to levels utilities now describe as critical.

Why are businesses in the crosshairs?

The water companies' call for non-essential use bans on businesses tells us where the shortfall is most acute. When utilities ask regulators for curbs on commercial consumption, it means reservoir levels have dropped far enough that household supply can only be protected by cutting industrial and commercial draw.

For operators in the six affected counties — hospitality, agriculture-adjacent food processing, landscaping, cleaning services and any water-intensive manufacturing — the practical risk is straightforward: restrictions on non-essential water use can interrupt operations, raise costs or force process changes on short notice.

The declaration also raises the prospect of further measures if conditions don't improve. Securing public supplies is the stated priority, and urgent steps are already underway. Companies with operations in the affected zones will want contingency plans ready before any ban takes formal effect.

What comes next?

The trajectory depends on reservoir recovery in the south-east and south-west, which remains at critically low levels today. The Guardian's October 15, 2026 report makes the near-term outlook explicit: urgent measures are being taken to secure public supplies, and water companies want non-essential business use curbed now.

The takeaway in plain words: six counties are officially in severe drought, reservoirs are critically low, and utilities are asking to cut business water use to keep public taps flowing — a signal that commercial restrictions, and the operational costs that follow, may be imminent.
