South East Water asks customers to use supplies with care
It says the weather has affected demand
Last updated 28th May 2026
South East Water is apologising to customers experiencing water supply issues.
The company says exceptionally high temperatures have, as expected, created very high demand for tap water supplies.
It said: "Despite planning for very high demand given the weather forecasts, by increasing output at our water treatment works across our supply area and putting extra water into the network, we're experiencing low storage across our supply area.
"For those in supply, we now need your help. Please use water for essential purposes only: drinking, washing and cooking.
"Simple swaps can make a huge difference, to help keep the taps flowing for everyone and prevent further measures.
"Stop using jet washes, hosepipes and sprinklers. Swap paddling pools for water blasters to keep kids cool and the car and patio can wait for a wash.
"Think about where you can swap tap water for recycled water. Reuse water from baths, showers and sinks in the garden.
"Act now, please do all you can to cut down on everything but essential water use, which is drinking, washing and cooking."
