Where these dates come from: dates marked “school” come from SIAL’s own published calendar; we re-check SIAL’s website about every 3 months for INSET days and any changes, and your calendar updates itself when we find them. Spotted a mistake? Tell us.

Questions parents ask
When is Kensington and Chelsea half term in October 2026?
Mon 26 Oct 2026 to Sun 1 Nov 2026 inclusive. Pupils at SIAL return on the next school day.
When does SIAL go back to school in 2026/27?
The first day of the 2026/27 academic year is Thu 3 Sep 2026.
Does SIAL set its own term dates?
SIAL is an other independent school, so it can set term dates that differ from Kensington and Chelsea 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.
Are INSET days included?
Not yet for SIAL. INSET days are set by each school individually rather than by the council, so they are not in the council calendar. Leave the INSET box ticked anyway: this is a live subscription, so once we confirm this school's INSET days they appear in your calendar automatically. You do not need to come back and re-add anything.
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.
