The Government's forthcoming official tourism strategy is set to support the campaign for extended daylight hours.
The strategy, set to be published at the end of the week, is expected to propose the adoption of "double summertime" in an effort to increase tourism to the UK.
However, sources at the Department for Culture said that any change would depend on the agreement of devolved authorities, including those in Scotland where many are against the move as they say it would make their mornings darker.
Double summertime would see the clocks in the UK being switched forward by an hour in relation to Greenwich Mean Time (GMT) during winter and then moved a further hour forward during summer.
The move would allow the sun to be out for an hour longer in the evenings, but would also mean that it would rise an hour later than it does currently.
Supporters claim a change could add millions to Britain's earnings from tourism and save thousands of tonnes of greenhouse gas emissions as people turn their lights on later.
But opponents say it would make life more difficult for early-rising farmers, increase the number of road accidents and make it more dangerous for children travelling to school.
Prime Minister David Cameron last year said he was ready to consider the proposal, adding: "The argument will be won when people across the country feel comfortable with the change."
