Record May heat has put a strain on UK water networks, with some areas seeing outages and reduced supply. This page answers the top questions people search for during such events, from why the strain is happening to practical steps households can take now. Explore the likely areas affected, how long shortages might last, who’s distributing bottled water, and what usage warnings to follow.
Extreme heat drives demand for tap water higher as people try to stay cool and hydrated. It also stresses treatment works and storage capacity, leading to pressure drops and intermittent supply in some regions. Officials warn the hot weather is the main driver behind the strain.
Reports show Kent and parts of Sussex experiencing outages and reduced pressure, with some customers facing intermittent supply. While the situation can change, authorities say the heatwave will continue to strain supplies in affected areas for as long as the high temperatures persist.
Conserve water whenever possible: use water only for essential needs, fix leaks, and avoid waste. Keep a small reserve of bottled water if you can, and follow local advisories on usage. Use water-saving habits (shorter showers, full loads for washing) and monitor pressure alerts from your water supplier.
Local water companies and emergency services are coordinating bottled water distribution for vulnerable households and areas most in need. Authorities also publish usage warnings and guidance to help the public reduce demand during peak heat.
Check your local water provider’s website or social channels for real-time updates, alerts, and instructions. Sign up for text or email alerts if available, and monitor trusted news outlets for the latest periodic updates.
