Half of England was officially declared in serious drought for the second year in a row in the week of August 2, 2026. The Environment Agency warned of serious consequences for the economy, environment, and wildlife. The declaration covers seven areas — East Anglia; Hertfordshire and London; Thames Valley; Hampshire and the Isle of Wight; Devon and Cornwall; the West Midlands; and Wessex. July brought just 7% of the rainfall normally expected across England, and only 1% in the south. Some parts of Devon had no rain for 50 days straight. (The Guardian, 2026-07-29; GOV.UK, 2026-07-29)

Helen Wakeham, director of water at the Environment Agency and chair of the National Drought Group, called a second consecutive summer drought "an exceptionally serious situation" with long-lasting impacts on the environment, wildlife, and economy. The Agency described it as a "flash drought," meaning it developed quickly because of unusually low rainfall and high temperatures rather than building up slowly. England has now had droughts in three of the past five years: 2022, 2025, and 2026. (The Guardian, 2026-07-29)

The drought is happening at the same time as the government's promise to build 1.5 million new homes by the end of the current parliament. The problem is that the areas with the worst water shortages are the same ones where the government wants to build: Hampshire, Kent, Hertfordshire, Essex, and Cambridgeshire. Drought linked to climate change, along with the water industry's failure to build needed infrastructure, means growth plans are running into environmental barriers. (The Guardian, 2026-08-02)

In Basingstoke and Deane, the council has been told to build more than 1,000 houses a year. Paul Harvey, the Independent leader of the council, said: "We cannot magic up more water." The council's water cycle study, which looked at whether there is enough water supply and sewage treatment for future residents, found that demand from new housing may exceed what can be supplied sustainably. Around Basingstoke, the struggle to find enough water for the people already living there is causing serious environmental damage to one of the largest remaining alkaline fens — a rare type of wetland — in southern England. Natural England says this fen is being pushed toward irreversible ecological collapse. (The Guardian, 2026-08-02)

Environment Agency mapping shows that even in normal conditions, there is no additional river water available for new homes or industry across about a third of England. Ali Morse, water policy manager at the Wildlife Trusts, said water scarcity is becoming an urgent issue in England even when there is no drought. In Cambridgeshire, the dried-mud basin of Grafham Water reservoir was photographed for the story. Local MP Pippa Heylings said a lack of water is a "deal-breaker" for the government's growth plans for the county. (The Guardian, 2026-08-02)

The water situation is severe. Even though record winter rainfall had refilled reservoirs and groundwater, England's reservoir storage had fallen to 7.4% below the normal level for that time of year. Almost half of all reservoirs are below normal levels, with Wimbleball (South West Water) and Blagdon (Bristol Water) both described as "exceptionally low." The River Thames has run dry at Ashton Keynes in Wiltshire, near where it begins, and 78% of rivers in England are at below normal or lower levels. Forty percent of the population are under a hosepipe ban. Seven water companies — Affinity Water, Anglian Water, Cambridge Water, Southern Water, South East Water, Thames Water, and South West Water — are restricting water use. (The Guardian, 2026-07-29)

Will Lang, the Met Office's chief meteorologist, said there was little sign of the widespread, lasting rainfall needed to help the areas most affected. The Environment Agency said current water reserves should be enough for the coming months until the next period of sustained rainfall. Six drought permits, which let water companies take water from alternative sources, have been issued in the north west and Yorkshire. One drought order was granted to the Environment Agency in the north west. (The Guardian, 2026-07-29; GOV.UK, 2026-04-08)

The problem goes beyond this immediate crisis. Ofwat, the regulator that oversees the water industry, projects the UK population will exceed 71 million by 2056 and says government housing targets will put additional pressure on water supply. The government's National Framework for Water Resources 2025 states that society's current use of water is unsustainable and that climate change will keep adding pressure. The Environment Act 2021 sets a target to reduce per-person water use from public supply in England by 20% by 2037-38. (Ofwat, 2026-03; GOV.UK, 2026-04-15; GOV.UK, 2024-12-20)

Research by Greenpeace UK found that water companies in England were wasting five times more water through leaky pipes than even a nationwide hosepipe ban could save. Paul Tompkins, deputy president of the National Farmers' Union, said the drought announcement should matter to everyone because water is vital to food production and food security. The Environment Agency recorded 61 incidents caused by drought and dry weather in the week of 17 to 23 July 2026. (The Guardian, 2026-07-29; GOV.UK, 2026-07-23)

The broader context is that the clash between the government's housing promises and England's shrinking water supply reveals a gap in planning that existed long before the current government took office. The National Framework for Water Resources 2025 explicitly states current water use is unsustainable, and the Environment Act 2021's target to cut per-person water use by 2037-38 depends on measures that are nowhere near being put in place. On the supply side, decades of underinvestment in reservoirs, pipes, and fixing leaks have left the system stretched thin. The Greenpeace finding puts the imbalance in sharp relief: households are asked to use less water during a hosepipe ban while water companies lose far more through leaky pipes than those bans could ever save. The result is that local councils in water-stressed areas are being told to meet housing targets that the available water simply cannot support.

The ecological stakes make the policy picture even more serious. Natural England's finding that the Basingstoke fen is approaching irreversible collapse shows that the trade-off is not just between growth and convenience, but between growth and protected natural habitats that may never recover. With a third of England having no additional river water available even in normal conditions, the real question is not whether housing targets will run into water limits, but how many local councils will raise those limits as a reason to hold back building, and whether the central government will accept that as a valid argument or push past it.
