Hosepipe Bans Expand as UK Heatwave Intensifies

Hosepipe bans have been implemented by five water companies across southern and eastern England, affecting more than 11 million customers as the United Kingdom faces its third heatwave of the year. The restrictions come as drought risk increases and temperatures continue to exceed 30 degrees Celsius.

Affinity Water, which serves 3.9 million customers, will introduce a ban in its central region from July 17, prohibiting the use of hosepipes for watering gardens, washing cars, or filling swimming pools. This follows similar restrictions already imposed by Anglian Water, Cambridge Water, South East Water, and Southern Water. High temperatures, with a high of 36C recorded, have led to early harvests and have impacted health, energy resources, wildfire risks, and transportation.

This marks the eighth day this year where temperatures have reached or exceeded 34C, surpassing the previous record of seven days set in 1976 and 2020. The Met Office confirmed that 2026 is the first year on record to experience temperatures of 35C or higher in May, June, and July.

Anglian Water will ban hosepipe use for its five million customers starting July 11, citing sustained hot and dry weather that has increased water demand by 20%. Dr. Geoff Darch, head of strategic asset planning for Anglian, noted the challenge of balancing supply and demand during this period.

Cambridge Water announced a ban for its 350,000 customers, the first in three decades, effective July 17. South East Water implemented a ban for 850,000 customers in Kent last Friday and has requested reduced water use in Hampshire and Sussex. Southern Water's ban for one million people in Hampshire and the Isle of Wight began on July 10.

Several other water companies are urging customers to voluntarily conserve water. Thames Water has asked its 16 million customers to cease using hosepipes, though no official ban is in place. Yorkshire Water has advised its 5.7 million customers to use watering cans instead of hoses. Severn Trent, Essex and Suffolk Water, Wessex Water, and Portsmouth Water are also encouraging water-wise practices.

The government has announced reforms to address water resource pressure, including plans for nine new reservoirs and over £104 billion in private investment for infrastructure improvements. Ministers are also considering changes to building regulations to mandate water-efficient appliances in new homes.

The heatwave has also led to disruptions in other sectors. Rail services are experiencing amended schedules due to the high temperatures affecting tracks and infrastructure. The UK Health Security Agency (UKHSA) has issued amber health alerts across England, warning of significant impacts on health and social care services. The National Fire Chiefs Council has highlighted an increased risk of wildfires, advising against the use of disposable barbecues in open areas.
