Questions parents ask
When is Westminster half term in October 2026?
Mon 26 Oct 2026 to Sun 1 Nov 2026 inclusive. Pupils at Halcyon London International School return on the next school day.
When does Halcyon London International School go back to school in 2026/27?
The first day of the 2026/27 academic year is Wed 2 Sep 2026.
Does Halcyon London International School set its own term dates?
Halcyon London International School is an other independent school, so it can set term dates that differ from Westminster Council's. The dates here come from the council calendar unless we have verified the school's own published dates, and every date is labelled with its source.
Can I get INSET days too?
Yes, INSET days are in the calendar where we have confirmed them from the school's own published dates, and each one is labelled with its source.
Will the calendar update by itself?
Yes. It is a live subscription, not a one-off copy: your calendar re-checks it automatically, so next year's dates appear without you doing anything, and any correction reaches you the same way. It is free, and you can unsubscribe in one click.
