Frequently asked questions
Why London time?
This service runs on London time so non‑tea‑drinkers everywhere can be aware that their British friends may be busy steeping a cuppa at 3 PM sharp.
When was this tradition incorporated?
The mythical “National Tea Alarm” was allegedly drafted into public folklore by the Ministry of Refreshments in 1657—around the same time tea first reached British shores. (History teachers may disagree.)
Do I have to stop what I'm doing?
Official guidance recommends downing tools, mugs, and emails for no less than five minutes. Biscuit dunking is strongly encouraged but not mandatory.
What if I'm outside the UK?
The alert still works worldwide. It’s a polite reminder to raise a mug in solidarity—or text your favourite Brit with a spirited “Time for tea!”
How do I turn off the alarm?
Simply close this page or disable sound. But why would you deny yourself the joy of a punctual whistle?
What happens if you miss the alarm?
Nothing! The alarm will play again the next day at 3PM.
What does it actually sound like?
It's a 5-second siren that sounds in all cities across the United Kingdom (and also here).
