Live time conversion and hour-by-hour comparison
This page shows the live time conversion between London and Singapore. The hour-by-hour chart above makes it easy to find overlapping business hours for meetings or calls. Green highlights indicate standard business hours (9 AM – 5 PM) in each city.
London and Singapore are 8 hours apart during winter (7 during BST). The practical overlap is early morning London / late afternoon Singapore: 8-9 AM GMT catches 4-5 PM SGT. This tight window means most London-Singapore coordination happens through a combination of one daily overlap call and asynchronous communication for everything else.
Singapore's post-independence evolution into a global financial hub has maintained strong ties with London. The London-Singapore financial axis is crucial for Asian-focused hedge funds, private equity, and corporate banking. Many multinational corporations use London as European HQ and Singapore as Asian HQ, making this time zone pair a structural feature of global business.
Singapore's legal system is based on English common law, and its financial regulations share DNA with London's frameworks. This legal alignment, combined with the English language, makes London-Singapore one of the most efficient cross-time-zone business pairs despite the 7-8 hour gap. Contract negotiations, regulatory discussions, and compliance reviews flow between the cities daily.
The most effective London-Singapore teams establish a single daily overlap window — typically 8:00-9:30 AM GMT / 4:00-5:30 PM SGT — for synchronous discussion, then handle all other communication asynchronously. This respects both sides' work-life balance while maintaining the collaboration rhythm. Singapore professionals taking late calls (after 5 PM SGT) for London's convenience should be balanced by London teams occasionally taking early calls (before 8 AM GMT).
