How Inset Offset works

Enter your school calendar once, and we find the longest breaks you can take without a fine — then show what we found when we price-checked those dates.

The idea: inset days offset peak prices

School-holiday prices spike because everyone travels at the same time. But your school's calendar has gaps most families never join up: inset (teacher training) days, weekends, half-terms and bank holidays are all days your child is authorised to be off.

Because inset days aren't term time, a day or two of training can extend a weekend into a genuine break that sits just outside the peak window — fully authorised, no permission needed. That's how inset days "offset" the peak-season premium.

The green, amber and grey system

Every day we show is colour-coded, so you can see fine risk at a glance:

By default we only show fully green windows. If you tell us you'd consider a few term-time days, we'll also surface longer windows that include amber days — clearly marked, so the choice is always yours. We haven't priced trips that need term-time absence, so those windows don't show a saving.

Three steps

About term-time fines

Taking your child out during term time can lead to a penalty notice, which is why fully authorised (green) windows are the safe default. Amber days are never hidden and never booked for you — if a window includes them, we say so plainly and point you to your school's own policy. Always confirm with your head before booking a term-time day.
