Teachers must get 1 break of "reasonable length" each day
This applies to the following staff in maintained schools:
- Teachers, as long as they work for more than 1 school session. They can take their break either between school sessions or between 12pm and 2pm. It does not count as directed time
- Deputy headteachers, assistant headteachers and teachers on the leading practitioners pay range. They should take this as close to the middle of the school day as possible
- Headteachers, but they must arrange for someone to cover for them while they're on break
This is set out in the STPCD (pages 45 and 50).
20 minutes is the minimum length, but it tends to be longer
In practice, unions will
