Quick answer
11 AM PST is 7 PM GMT in London (winter). In summer, 11 AM PDT is 7 PM BST. This is evening in the UK — two hours past the standard end of the UK working day. Treating this as a standard meeting slot for London participants is not appropriate without explicit individual agreement.
11 AM Pacific is evening in London — not "slightly late"
The most common mistake made by Pacific-based teams scheduling with London is to look at 11 AM Pacific and think "that should be fine, it's not that late." 11 AM PST reaching London at 7 PM GMT is not a slightly late afternoon call. It is evening. Most London professionals have finished work at 5 PM, had dinner or evening commitments by 6 PM, and are fully into personal time at 7 PM. A 7 PM meeting invite from a US colleague is functionally equivalent to asking them to cancel a personal evening commitment.
This is the slot where the Pacific team is most likely to book inadvertently. 11 AM Pacific sits comfortably before the midday lunch break, feels unhurried and productive, and has no obvious signals that it might be problematic. The problem is invisible to Pacific participants and very visible to London ones.
When Pacific teams make this mistake
The pattern usually appears when a US West Coast organiser books a meeting using the Pacific time, does not check what that time is in London, and sends the invite. The London participant accepts because they feel unable to object, attends the 7 PM call, and says nothing about the time. This continues for months as a recurring meeting until the London participant changes role, raises the issue, or leaves the organisation.
The fix is structural: before sending any Pacific meeting invite with London participants, verify the London time. The SF–London planner and LA–London planner show at a glance which hours overlap within standard working windows for both cities.
Legitimate uses for 11 AM Pacific / 7 PM London
Explicit agreement: Some London-based employees in US companies have UK-facing roles that include regular evening calls as part of a formally agreed schedule. This is a deliberate employment arrangement, not the default. It should be in writing.
Genuine emergencies: A product outage, critical client escalation, or time-sensitive decision that cannot wait. One-off emergency calls at 7 PM London are a fact of global work; standing weekly syncs are not.
Async-first with London recorded content: If the 11 AM Pacific team needs London context, ask the London participant to record a 3-minute async update before they finish their workday at 5 PM. The Pacific team reviews it during the 11 AM meeting without requiring London to join live. This is a better model than live attendance at 7 PM.
Scheduling drawbacks
- 7 PM London is two hours past the standard UK working day — evening, not "slightly late"
- As a recurring meeting, it creates ongoing wellbeing and retention issues for London participants
- Meeting quality is lower when London participants join from personal time rather than work mode
- Legal and HR risk in some UK jurisdictions around regular out-of-hours meeting expectations
What to do instead
The realistic options for Pacific teams who cannot hold meetings before 11 AM are: (1) make the meeting async — record it and share a timestamped summary; (2) require London to send an async update before their 5 PM that the Pacific team reads at 11 AM; (3) shift the meeting to a day of the week when an 8 AM Pacific start is feasible, even if the rest of the week uses 11 AM. One earlier meeting per week can carry the weight of a recurring decision that would otherwise require live London attendance at 7 PM.
What is 11 AM PST in London?
11 AM PST is 7 PM GMT in London during winter. In summer, 11 AM PDT is 7 PM BST. This is evening in the UK — two hours past the standard end of working day at 5 PM. Treating this as a standard meeting slot for London participants without explicit individual agreement is not appropriate.
Why do Pacific teams accidentally book 11 AM meetings with London?
11 AM Pacific is a comfortable, productive time that shows no obvious signals of being problematic. The Pacific organiser books it without checking the London time. At 7 PM, London is two hours into personal time, but the scheduling mistake is invisible to the Pacific side and often goes unreported by London participants who feel unable to object. The solution is to always verify the London time before sending any Pacific morning invite.
How should I handle London participants if I can only meet at 11 AM Pacific?
Three options: (1) use async — record the 11 AM Pacific meeting and share a structured summary within one hour; (2) ask London to send a short recorded or written update before 5 PM their time, which the Pacific team reviews at 11 AM without requiring London to join; (3) designate one day per week for an earlier Pacific start (8 AM Pacific / 4 PM London) for any decisions requiring real-time London input. Save the 11 AM Pacific slot for Pacific-only matters.
Does DST change 11 AM PST in London?
No — it stays at 7 PM London for most of the year. Both the US West Coast and the UK observe daylight saving time together, keeping the 8-hour gap. During the brief transition windows in late March and late October, the gap is temporarily 7 or 9 hours, shifting the London time to 6 PM or 8 PM. Either way, this slot falls outside standard UK working hours.
