How far apart are London and Perth?
Perth (Australia) runs 7 hours ahead of London (United Kingdom). In practical terms, the working day in Perth starts while London is still in the early hours or asleep, which is what makes scheduling between the two take a little planning.
Best time to schedule a call or meeting
The comfortable window — when both cities are inside normal 9-to-5 hours — runs from about 9:00 AM to 10:00 AM in London time, roughly 1 hour. Schedule calls inside that band and neither side is working unsocial hours.
A note on daylight saving
London observes daylight saving but Perth does not, so the gap between them changes by an hour for part of the year. The 7 hours shown here is the current offset; expect it to shift around the daylight-saving changeovers (typically late March and late October in the Northern Hemisphere).
