The United States has taken a significant step towards ending its twice-yearly clock changes, reopening a debate that could eventually reach British workplaces.
On 14 July 2026, the US House of Representatives voted by 308 votes to 117 in favour of the Sunshine Protection Act. The proposed law would establish permanent daylight saving time across participating US states, removing the need to move clocks forward in spring and backwards in autumn. However, the proposal must still pass through the US Senate before it can become law.
Supporters argue that keeping lighter evenings throughout the year could benefit businesses, encourage outdoor activity and remove the disruption associated with changing the clocks. Critics warn that permanent summer time would create darker winter mornings, particularly in northern areas, potentially affecting commuters, schoolchildren and workers starting early shifts.
The question for Britain is whether a permanent change in America would increase pressure for the UK to reconsider its own system.
Would the UK have to follow America?
The UK would not be legally required to follow any American decision.
British time arrangements are determined domestically. Under the present system, UK clocks move forward on the last Sunday in March and return on the last Sunday in October. In 2026, British Summer Time began on 29 March and will end on 25 October.
However, a permanent American change would affect businesses, workers and organisations operating across the Atlantic.
For much of the year, London is normally five hours ahead of New York. If the eastern United States remained permanently on daylight saving time while Britain continued returning to Greenwich Mean Time each winter, London would be only four hours ahead of New York during the British winter.
This would not necessarily be harmful. A smaller time difference could provide longer overlapping working hours for British companies dealing with American customers, suppliers and colleagues. Meetings could be held earlier, responses might be received more quickly, and financial, technology, legal, media and customer-support operations could find transatlantic communication easier.
There could also be complications. International flight schedules, digital systems, automated appointments and global trading arrangements would need to account for changing differences between Britain and America. US airlines have already raised concerns about the planning and scheduling work that a permanent change could create.
What would permanent summer time mean for UK workers?
The strongest argument for permanent British Summer Time is that it would provide more daylight after work during winter.
For workers finishing at 4pm, 5pm or 6pm, lighter evenings could improve visibility during the journey home. Construction, delivery, maintenance, retail, hospitality, leisure and outdoor businesses might also benefit from additional usable daylight later in the day.
Longer winter evenings could encourage people to visit town centres, shops, restaurants and leisure facilities after work. This could support employment in sectors that depend heavily on afternoon and evening activity.
However, daylight cannot be created by changing a clock. Moving an hour of daylight into the evening means losing it from the morning.
Permanent British Summer Time would produce later winter sunrises, with the effect becoming more pronounced across northern England, Scotland and Northern Ireland. People travelling to early shifts could spend more of their morning journey in darkness. This would be especially important for construction workers, warehouse staff, drivers, agricultural workers, NHS employees and others beginning work before the conventional nine-to-five working day.
Previous UK analysis has recognised this central trade-off: later evening daylight would be gained at the cost of darker mornings.
Is stopping the clock change healthier?
There is substantial support for ending the twice-yearly disruption, but less agreement about which time should become permanent.
Sleep specialists generally support permanent standard time rather than permanent daylight saving time. The American Academy of Sleep Medicine argues that standard time aligns more closely with natural light patterns and the body’s internal clock.
This distinction matters. Ending clock changes may reduce short-term sleep disruption, but keeping summer time throughout winter could expose workers to darker mornings and make waking naturally more difficult.
The debate is therefore not simply about whether the clocks should stop changing. It is also about whether permanent time should prioritise morning light or evening light.
Should Britain align with the United States?
Britain should not automatically copy the United States. The two countries have different geography, daylight patterns, working practices and transport systems.
The UK should instead conduct a worker-focused assessment covering road safety, sleep, productivity, early-shift employment, regional daylight differences and the needs of businesses operating internationally.
A permanent system could offer greater certainty and remove the inconvenience of changing clocks twice each year. Nevertheless, any change must recognise that the effects would not be shared equally. Office workers finishing in the evening may welcome additional light, while workers beginning shifts before sunrise could face longer journeys in darkness.
The Workers Union says
The debate must place working people at its centre.
Any decision should be based on independent evidence rather than simply following an overseas policy. The experiences of night workers, drivers, construction staff, healthcare employees, emergency workers and people working early shifts must be considered alongside the potential commercial benefits of lighter evenings.
The Workers Union believes that consistency may benefit workers and employers, but the choice between permanent standard time and permanent summer time requires careful examination.
The objective should be clear: a system that supports safe journeys, healthy working patterns, dependable international business and the everyday lives of workers across every part of the United Kingdom.
