McDonald's breakfast in the UK typically ends at 11:00 AM. At 24-hour McDonald's locations, breakfast service begins at 6:00 AM and ends at 11:00 AM. These breakfast hours are consistent across seven days a week, Monday to Sunday. On weekdays, some locations may stop breakfast service earlier, around 10:30 AM, but generally, 11:00 AM is the standard cutoff time for breakfast items. After breakfast ends, the menu transitions to regular lunch and other items.
