As England teeters on the brink of official drought status, nearly 23 million people will be forced to abide by hosepipe restrictions within days - with Thames Water joining the list of utility companies imposing bans. The water supplier's measures, which affect over 10 million customers in London and the Thames Valley, come into force from Thursday, 23 July 2026.
The unprecedented move is a direct result of months of abysmal weather conditions, including three intense heatwaves and the driest spring on record for England and Wales. Water reserves have been severely depleted, particularly across southern and south-eastern England, where only 40% of typical rainfall was recorded during the spring months.
Thames Water cited a staggering surge in demand for water - up by 10% in the Thames Valley and home counties and 7% in London - equating to an extra 100 million litres per day. This amount is equivalent to supplying the entire city of Manchester. According to Nevil Muncaster, Director of Strategic Resources at Thames Water, implementing the ban was essential to safeguard both customer supplies and the environment.
Notably, this announcement brings Thames Water into line with South East Water, which announced its own hosepipe restrictions affecting 2.4 million customers across Sussex, Surrey, Hampshire, and Berkshire from Saturday, 25 July 2026. Meanwhile, other water companies including Affinity Water, Anglian Water, Cambridge Water, Southern Water, and South West Water have already imposed similar measures on their customers.
Data suggests that only 13% of rivers are at normal levels for this time of year, while national reservoir storage stands at a worrying 78.8%, approximately 5% below the long-term average. The Met Office's Chief Meteorologist, Will Lang, noted that much of England has endured an unusually warm and dry first half of summer - with July proving particularly parched in many areas.
The severe weather consequences stretch beyond water availability, causing significant damage to the environment and agricultural sector. Rob Gazzard, advisor to the Forestry Commission on wildfires, highlighted the drastic reduction in natural resistance to fires due to extremely dry soils and vegetation, leading to rapid spread and increased intensity of the 53 reported wildfires across the country. Paul Tompkins, Deputy President of the National Farmers' Union, expressed deep concern about the long-term impact of this extreme weather on crops and livestock.
