Top shops and malls along the Style Mile will stay open until 7pm on Mondays, Tuesdays, Wednesdays and Fridays, and until 8pm on Thursdays.
Leading malls, like Buchanan Galleries, St Enoch Centre and Princes Square plus department stores House of Fraser and Debenhams have signed up to the initiative, led by Glasgow's City Centre Retail Association (CCRA) and Glasgow City Marketing Bureau (GCMB).
It's great news for hard-pressed, time-poor workers who can now catch up on shopping after they leave the office - and it's a huge boost for Glasgow's retail and entertainment economies.
A similar campaign in Newcastle saw an increase of 17 per cent in average consumer spend between the hours of 5pm and 8pm, with an estimated £247 million generated between 2010 and 2013.
Paul Mitchell, chairperson of the CCRA, explains: "This initiative is the first step towards our ambition of stores opening until 9pm by next summer, aligning Glasgow with other European shopping hubs such as Paris, Milan and Barcelona and capitalising on the volume of people expected in the city for the Commonwealth Games."
With more than 1500 shops, 38,000 employees and around half a million square metres of floor space, Glasgow remains the second biggest retail destination in the UK. It is worth £2.4 billion a year, according to independent research company CACI in its 2011 Retail Footprint study.
"Retail of all sizes, from the largest chain to the smallest niche boutique is the very heartbeat of Glasgow," says Glasgow Chamber of Commerce chief executive Stuart Patrick. "Shopping is a major leisure activity in its own right for both residents and tourists, playing a significant role in the £601m spent by some 2.3m visitors coming here each year."
Councillor Gordon Matheson, leader of Glasgow City Council and chairperson of Glasgow City Marketing Bureau believes Glasgow's late night shopping initiative will help the city overcome competition from out of-town shopping malls and rapid growth in online shopping.
He explains: "This initiative will incentivise shoppers and visitors to come to the city in the evening or stay longer in the city centre at the end of their day, benefiting not only the retail industry but also the city's leisure market and wider economy."
Ryan James, chairman of Glasgow Restaurant Association (GRA), adds: "Extended store opening hours is great news for Glasgow's night-time economy as it presents an ideal way of enticing shoppers, visitors and people finishing work to remain in the city centre and consider visiting the city's diverse variety of first-class restaurants, bars and entertainment venues."
