Cause

A dry winter followed by the driest July in England since 1935 and a July heatwave that took UK temperatures above 40 °C for the first time on record, sharply raising evaporative demand at the moment soil moisture was already depleted.

Impact

  • Drought declared across eleven of the fourteen Environment Agency areas
  • Hosepipe bans affecting roughly 20 million people
  • The source of the Thames moved several miles downstream as the headwaters dried
  • Reduced crop yields and early harvest across arable England

Response

Temporary use bans by most southern and eastern companies, abstraction restrictions, and Environment Agency drought permits allowing reduced compensation flows.

Aftermath

Ofwat and the Environment Agency both pressed companies on leakage and on the slow progress of new resource schemes; the event is widely cited in the case for the reservoirs and transfer schemes now in the regulatory pipeline.
