How to use the online timer
If your first countdown has ended while you are still touring the Houses of Parliament, starting another for one hundred and fifty-eight minutes gives the rest of the visit a clear boundary. You can continue through the building without repeatedly checking the clock, while keeping your later plans in Westminster in view.
As the Parliament tour continues into this second countdown, the timer tab may slip behind a booking confirmation, map or message. It should keep counting while it remains open, although a phone may restrict activity when the browser is left in the background for a long stretch. Returning to the tab during a natural pause lets you confirm that the display is still moving and that your expected finish has not drifted.
With the tour still under way after one signal, treat the next alert as the outer edge of the visit rather than the moment your following commitment begins. Leave a buffer for collecting belongings, passing through the exit and walking away from the Parliamentary Estate. If the visit finishes early, that spare time can absorb a slow departure; if it runs late, you already know how much flexibility remains before the next thing in your day.
Common questions
What might make a Parliament tour finish before the second countdown ends?
A shorter route, fewer pauses or moving through the building at a steady pace may leave time unused. Keep the remaining minutes as a buffer for leaving the Parliamentary Estate and reaching your next stop.
What if the Parliament tour is still continuing when this second countdown finishes?
Check how soon your next commitment begins before staying longer. Departure from the building and the walk across Westminster will also use part of the time you have left.
