How to Close Your Office Safely: A Practical Guide
Closing the office is the mirror of opening it, and the one with higher stakes. A missed window, an alarm that never got set, or a laptop left visible in a street-facing room can cost real money overnight. A closing SOP makes the end of the day a calm sequence instead of a rushed dash for the door: shut down, walk through, secure, hand over. It’s the cheapest insurance policy an office has.
When to Use This
Use this SOP in any office with a physical premises that someone locks up in the evening. It matters most when closing duties rotate, the last person out varies by day, or when closing falls to whoever stays latest, which is exactly the person most likely to rush it. If your office has ever been left with the alarm unset, a kitchen appliance on, or a window open overnight, you already know why this exists.
The SOP also protects the person closing up. A written procedure means they know what’s expected, they know who to call if something’s wrong, and they have a record that they did the checks, useful the morning after something goes missing.
How to Fill It Out
The header box. Who prepared it, who owns it, the version, the date issued, and the review date. The owner is usually the office manager, someone with authority over security and premises.
Fields to complete before use. Replace every bracketed field with your real details, closing time, office manager name, alarm company name and phone, lost-property box location, overnight air-conditioning setting, then delete the example rows. Check that every number is current; a closing SOP with an old alarm company number is a liability.
End-of-day shutdown steps. The sequence: close at the stated time, ask staff to shut down or lock computers and put shared printers on standby, switch off kitchen appliances at the wall (kettle, toaster, microwave, coffee machine, name yours), set air conditioning to the overnight setting, close blinds in street-facing rooms, switch off non-essential lights. The appliance list is worth getting right, kitchen appliances left on are one of the most common small-office fire risks, and “at the wall” matters because standby is not off.
Security and alarm procedure. The final walk-through: once around the whole office confirming windows closed, internal doors locked, and no one remaining in meeting rooms, washrooms, or the kitchen. Then lock the main entrance, set the alarm, and wait for the panel to confirm it’s armed before leaving. That confirmation step is the one people skip, standing outside for thirty seconds to watch the panel arm is the difference between “I think I set it” and “I know I set it.” If the alarm won’t set, re-check doors and windows once, then call the alarm company and inform the office manager. The SOP is explicit: do not leave the building unalarmed without reporting it.
Left-behind items and lost property. Log found items with what they are, where they were found, the date, and where they’re stored, the lost-property box location you filled in above. This takes thirty seconds and prevents two common headaches: the employee who insists their umbrella was “stolen from the meeting room,” and the slow accumulation of unclaimed items nobody dares throw away. Set a retention rule with the office manager (for example, unclaimed items disposed of after 30 days) and note it here.
Handover notes for the next day. The written handover: deliveries expected tomorrow, anything unusual for the morning opener (a meeting moved, a repair scheduled), and any fault found during closing. This section is the bridge to the opening SOP, the closer tells the opener what to expect, in writing, instead of relying on a message that might not be seen.
Exceptions and escalation. What to do when the close doesn’t go normally: alarm won’t set, a stranger is still in the building, a water leak is discovered, the last staff member won’t leave. Each scenario gets an action and a number to call on the same row.
Completion checklist. The daily sign-off confirming the shutdown and security checks were done. Keep the completed checklists, a shared folder or a binder, for at least a few months; if a break-in or loss is reported, they’re your evidence the office was secured.
Common Mistakes
1. Letting the last person out improvise. When closing is whoever-stays-latest’s job, it gets done by tired people in a hurry. A written sequence means the same standard holds regardless of who’s doing it or how late it is.
2. Setting the alarm without confirming it armed. Pressing the buttons is not the same as the system being armed. The walk-away confirmation, watching the panel, waiting for the exit timer, is a small habit that prevents the most common closing failure.
3. Skipping the walk-through. Windows, washrooms, kitchen, meeting rooms, the rooms nobody thinks about are the ones where someone gets locked in overnight or a window gets left open in a storm. The walk-through is the whole point; everything else is details.
4. No handover to the morning. The closer who found a leaking tap and told nobody has just bought the opener a flooded kitchen. A two-line written handover costs nothing and connects the closing SOP to the opening one.
Who Needs to Sign Off
The office manager prepares and owns this SOP; a senior manager approves it, given the security and insurance implications. Everyone who might close up, team leads, senior staff, the cleaner with keys, reads it and walks through it once with the owner before doing it solo. If your insurer has requirements about alarm-setting or keyholding, check the SOP against them and note any specific compliance in the document.
How Often to Review and Update
Review every six months, and update immediately when anything changes: new alarm system or codes, alarm company change, office layout or entrance changes, new kitchen equipment, or a different lost-property arrangement. After any overnight incident, break-in, leak, alarm failure, review the SOP as part of the debrief. The incident will tell you exactly which check was missing or which escalation didn’t work; fix it while the lesson is fresh.
