INSTIGATION AND EARLY YEARS
British Summer Time
PERIODS OF DEVIATION
In the summers of 1941 to 1945, during the
Second World War
An inquiry during the winter of 1959–60, in which 180 national organisations were consulted, revealed a slight preference for a change to all-year GMT+1, but instead the length of summer time was extended as a trial. A further inquiry during 1966–67 led the government of Harold Wilson to introduce the BRITISH STANDARD TIME experiment, with Britain remaining on GMT+1 throughout the year. This took place between 27 October 1968 and 31 October 1971, when there was a reversion to the previous arrangement.
Analysis of accident data for the first two years of the experiment, published by HMSO in October 1970, indicated that while there had been an increase in casualties in the morning, there had been a substantially greater decrease in casualties in the evening, with a total of around 2,500 fewer people killed and seriously injured during the first two winters of the experiment, at a time when about 1,000 people a day were killed or injured on the roads. However the period coincided with the introduction of Drink-Driving legislation, and the estimates were later modified downwards in 1989.
The trial was the subject of a House of Commons debate on 2 December 1970 when, on a free vote , the House of Commons voted by 366 to 81 votes to end the experiment.
DEBATES ON REFORM
Campaigners, including the Royal Society for the Prevention of
Accidents (RoSPA) and environmental campaigners 10:10 , have made
British Summer Time
RoSPA suggests this would reduce the number of accidents over this period as a result of the lighter evenings. RoSPA have called for the 1968–71 trial to be repeated with modern evaluation methods.
While 10:10 generally agree with the safety benefits, their Lighter Later campaign focuses on the potential energy benefits of Single/Double Summer Time, arguing that the change could "save almost 500,000 tonnes of CO2 each year, equivalent to taking 185,000 cars off the road permanently".
These proposals are opposed by some farmers and other outdoor
workers, and many residents of
Others have proposed the abolition of BST entirely, favouring GMT all year round. Advocates cite in their support a lack of practical gains from the adjustment of time, arguing instead that changes in school and/or business hours would achieve similar results without disrupting a scientific standard.
CURRENT STATUTE AND PARLIAMENTARY ATTEMPTS AT CHANGE
The current arrangement is now defined by the Summer Time Order 2002 which defines BST as
...the period beginning at one o'clock, Greenwich mean time, in the morning of the last Sunday in March and ending at one o'clock, Greenwich mean time, in the morning of the last Sunday in October. — The Summer Time Order 2002
This period was stipulated by a Directive (2000/84/EC) of the
In part because of Britain's longitudinal length, debate emerges most
years over the applicability of BST, and is the subject of
parliamentary debate. In 2004, English MP
Nigel Beard tabled a Private
Member\'s Bill in the House of Commons proposing that England and
Wales should be able to determine their own time independently of
In 2005, Lord Tanlaw introduced the Lighter Evenings (Experiment)
Bill into the
House of Lords
THE DAYLIGHT SAVING BILL 2010–12
The Daylight Saving Bill 2010–12, a private member's bill by Conservative backbench MP Rebecca Harris , would have required the Government to conduct an analysis of the potential costs and benefits of advancing time by one hour for all, or part of, the year. If the analysis found that a clock change would benefit the UK, the bill required that the Government initiate a trial clock change to determine the full effects.
In 2010, Prime Minister
David Cameron stated he would seriously
consider proposals in the bill. The bill was only likely to be passed
with Government support. Despite initial opposition in
The bill was debated again in Parliament in November 2011 and sent to
committee in December 2011. In January 2012, the bill was again
debated on the floor of the House of Commons where it was filibustered
out of Parliament by opponents.
