Dark by four, empty by Christmas: security through the winter peak
Two things happen to security work in December, and they pull in opposite directions. Retail and licensed premises get busier than at any point in the year, and everything else empties out — offices, industrial units, construction sites and void property, all left alone for the longest unbroken period of the calendar. Both halves get harder in the dark and the cold.
A patrol in bad weather is a patrol that shortens
Nobody plans to cut a patrol. It happens because it is sleeting, the route is long, and the points at the far end of a site are the ones you reach last. A patrol that shortens in bad weather is the predictable outcome of a route designed in summer, and the log will look identical either way.
The honest fix is to design for the conditions: fewer points covered properly rather than more covered nominally, and somewhere on site an officer can warm up without leaving the route for twenty minutes. The patrol record keeps findings and action in separate columns for a reason, and in bad weather it is the action column that slips.
The timing point still holds too, and matters more now: the earlier it gets dark, the longer the window in which a predictable patrol schedule is useful to somebody watching the site.
Void sites over the shutdown
A void or construction site left for a fortnight is the classic December instruction, and it is usually written in a hurry. The assignment instructions for that period need to say more than the summer version, not less — what the officer does about storm damage, standing water, a failed light, a gate that has blown open, and at what point they stop checking and call somebody.
The escalation numbers are the part that fails. A set of instructions with a mobile for somebody who left in March is the most common serious defect in the document, and the holiday period is precisely when that is discovered — by an officer at three in the morning with water coming through a roof. Verify the numbers in November, and get an out-of-hours contact who is genuinely available over the break, which is covered in what good assignment instructions look like.
Lone working, in the cold, for longer
Lone working is the normal condition in this trade rather than an exception, and winter sharpens it. An officer who falls on ice on an external staircase at two in the morning, on a site nobody will visit for days, is relying entirely on somebody noticing that a check-in did not happen.
- A check-in arrangement with somebody actually watching it, and a defined point at which silence triggers a response
- Cold-weather provision that is real — somewhere to warm up, and PPE suitable for standing still outdoors rather than walking
- Confirmation that the person who notices a missed check-in is also working over the holiday period
- A plan for access and egress in ice and dark, including the walk to and from the vehicle
- Agreement that an officer who stops a patrol for genuinely unsafe conditions has made the right call
That last one costs nothing and changes behaviour. An officer who believes a shortened patrol will be questioned will complete the patrol and write it up as normal, which is worse for everybody than an honest entry.
Peak staffing and the licence check
The other half of December is extra officers for retail, events and licensed premises, often at short notice and often through agencies. They are inside your compliance picture from the first shift, and the check that matters is not the card — it is the register, on the day, including the sector the licence actually covers.
Deploying somebody on work their licence does not cover is the same exposure as deploying them unlicensed, and it is invisible on a tracker that only watches expiry dates. The seasonal version of the problem is in licence expiry as an operational problem: a licence lapsing over the holiday is a shift nobody can cover on a day nobody is in the office to fix it.
Pull every expiry falling between mid-December and mid-January forward now, and use the licence check record so the date you looked is on the file rather than the date on the card.
Write it down while it is happening
Winter produces more to record and worse conditions in which to record it — weather damage, failed lighting, flooding, intruders drawn by an empty site. An occurrence book written at the time is evidence; one written up at the end of a cold shift is a recollection, and the difference shows the first time anybody asks.
- Design patrol routes for winter conditions rather than letting them shorten quietly in bad weather.
- Void-site instructions need more detail over the shutdown, not less — especially what to do about damage.
- Verify every escalation number in November; the holiday period is when a stale one gets found.
- Lone working controls depend on somebody watching the check-ins, and that person needs to be working too.
- Check the register and the sector for every extra officer, not just the card and the expiry date.
- Pull licence expiries falling across the holiday forward rather than meeting them on a bank holiday.
