Thames Water has issued a warning to local councils and residents as soaring temperatures and record-dry conditions place unprecedented pressure on water supplies across parts of Buckinghamshire and Oxfordshire.
In a statement to local authorities, the utility company confirmed that while no homes are currently without water, areas across postcodes HP14, HP16, HP17, HP18, HP22, and HP27 — including communities such as Waddesdon, Princes Risborough, Long Crendon, Grendon Underwood, and parts of north-west Oxfordshire — may experience reduced water pressure in the coming days and over the weekend.
Thames Water attributed the issue to a combination of unusually high demand and ongoing emergency maintenance on key pumping stations, limiting the movement of water through their network. As a precautionary measure, bottled water is being distributed to vulnerable residents and is expected to be delivered to schools in affected areas today.
Despite the challenges, Thames Water reassured residents that widespread outages are "highly unlikely," and they are doing "everything we can to keep all our customers in supply with top-quality drinking water."
"With the driest spring in over 100 years and a forecast of rising temperatures, our systems are under real strain," a spokesperson said. "We're fixing leaks, using smart technology to manage water pressure, and deploying tankers to transport extra water where it's needed most."
While no hosepipe ban is currently in place, the utility is encouraging all residents — particularly those in the Slough, Wycombe, and Aylesbury areas — to use water responsibly. "Every drop counts," the company emphasized, offering practical tips such as shortening showers and turning off taps while brushing teeth.

Local authorities are continuing to monitor the situation closely and will provide updates as needed.
