The insurance marketplace has told its 800 or so employees that they are no longer allowed to drink alcoholic beverages from 9 a.m. to 5 p.m, the New York Post reports. The decision comes as the company wants to be “in line with much of the business in London’s financial sector,” according to the Post—not because of any alcohol-related issues.

“It provides clarification on the rules around alcohol consumption, which is prohibited during business hours,” a Lloyd’s spokesperson told the Post in a statement. “The guidance removes any ambiguity on the policy.”

Though it was popular for London’s financiers to drink during the day about a decade ago, this tradition has since taken a backseat at many companies in the city’s financial sector. But Lloyd was one of the biggest employers to not change its rules, notes the Post—at least, until now.
