Household electricity bills could be cut by over £400 a year if the October clock change is scrapped, a heating expert has claimed.
Professor Aoife Foley, of Queen's University Belfast, says the cost of living crisis has become an "energy war" and axing the clock change would dramatically reduce demand at peak times. The clean energy specialist has said the move would save households £1.20 a day.
The proposed solution comes as UK households brace for power cuts after the National Grid warned three-hour blackouts could be imposed on 'really, really cold' winter days.
The EU has been consulting for years on whether to forgo the annual shift in time. The bloc was set to scrap clock changes in 2021 but the move stalled amid the pandemic.
Professor Foley said: "By simply foregoing the winter Daylight Savings Time (DST) in October, we save energy because it is brighter in the evening during winter, so we reduce commercial and residential electrical demand as people leave work earlier, and go home earlier, meaning less lighting and heating is needed.
"We are no longer in an energy crisis in Europe, but an energy war and dependent on weather conditions. This winter it is very likely we may need to start rationing energy very seriously to avoid bigger energy issues in December and January when gas reserves start to run low."

She added: "There is no doubt that by foregoing the daylight savings in winter we would save a lot of energy, reduce our bills and carbon emissions during this energy war, and especially during a cost of living crisis."
Prof Foley calculated this would flatten the evening peak curves on energy demand by up to 10 per cent if commercial demand is included.
Evening energy demand peaks between 5pm and 7pm in a surge the National Grid may struggle to power this winter.
Professor Foley's calculations do not include savings in the commercial or industrial sectors, but she says if they were included "there would be even more significant energy, cost and emissions reductions for hard strapped businesses and the public."
Back in 1907, Willem Willet, a builder - and interestingly, the great, great grandfather of Chris Martin from Coldplay - initially proposed the daylight savings plan. It was then introduced in 1916 as a war time effort to reduce energy demand and help with earlier day light hours in the morning.
Since 2002, most countries in the European Economic Area adjusted their clocks on the last Sunday in March and October, but there was some variation. Critics of scrapping daylight savings are concerned about road traffic collisions and there also would be time zone issues between the UK and Ireland.
Prof Foley cited research showing that most road fatalities occur on a Friday, Saturday, Sunday and Monday and that speed, tiredness and alcohol is an influencing factor.
The energy expert commented: "Most road collisions occur in good visibility during the day and outside of built-up areas.
"It would be great if the UK Government consulted with the Irish Government on an emergency proposal to abolish daylight savings this year. Obviously in Ireland two different time zones would be impossible but Ireland would also make energy and emissions savings and enhance security of supply."
