For the office manager, operations lead or deputy head who keeps the auditorium, halls and meeting rooms in a paper diary — and gets the phone call when two events arrive at once.

One shared Excel file for every space: auditorium, main hall, meeting rooms, conference room, music and art rooms, counselling room. Staff pick the space, date and period from dropdowns, type the group and their name — and the Status column answers instantly: ✅ Booked, or ❌ Already booked / fixed timetable / out of service, so they pick another slot. Nobody can double-book, and nobody has to referee.

WHAT’S INSIDE
• Book Here — the shared log. First come, first served, enforced by formulas.
• Week View — one space, one week, every period. Printable.
• Today — every space today. Print it for reception.
