About a 8:45 am alarm
An 8 am alarm works for flexible hours, remote working and weekend mornings. Streets are already busy by this time, so there is little benefit in waking later on a commuting day. A quarter-to time gives you a short run-up to anything that starts on the hour. It suits people who prefer a quick start, such as a fast breakfast and an immediate commute, and it is often used by those who want the last possible moment of sleep without being late.
In London the sun is already up at 8:45 am in every month. It is still dark, or already dark, at that time in none.
