The numbers
The UK will adjust its clocks forward by one hour on Sunday, March 29, 2026, at 1am, marking the official start of British Summer Time. This change is designed to make better use of natural daylight during the spring and summer months, resulting in lighter evenings across the country.
As the clocks move from 1am to 2am, many will experience a loss of one hour of sleep. While this may be a minor inconvenience, it also signals the arrival of longer days, with up to 16 hours of daylight in London by June. “The clocks will go forward by one hour next weekend, marking the start of British Summer Time and bringing lighter evenings across the UK,” a spokesperson noted.
The practice of changing the clocks was first introduced on May 17, 1916, during World War I, as a measure to conserve fuel. The idea was proposed by builder William Willett in a 1907 pamphlet titled “The Waste of Daylight,” highlighting the potential benefits of utilizing daylight more effectively.
Over the years, the policy has evolved, with British Double Summer Time even being implemented during World War II, moving clocks two hours ahead of GMT. Today, the tradition continues, with the clocks set to go back one hour on the last Sunday in October, allowing for a return to standard time.
In 2019, the European Parliament voted in favor of ending seasonal clock changes, yet the reform has not been implemented, leaving the UK to continue with its traditional clock adjustments. Observers remain hopeful that discussions around the future of Daylight Saving Time will lead to a resolution that aligns with public preference.
As the date approaches, communities across the UK are preparing to embrace the longer days and warmer evenings that British Summer Time brings. Whether it’s enjoying outdoor activities or simply basking in the extra sunlight, the change is welcomed by many.
