The situation
Northgate provide manned guarding and key holding across 31 sites in Greater Manchester — a mix of distribution parks, two shopping centres and a rolling programme of construction sites. Eighty-four officers, roughly a third of them part-time or bank staff picking up cover at short notice.
The operations director built every rota personally, in a spreadsheet, on a Sunday evening. It took two evenings a week once the changes and the chasing were counted. The finished rota went out as a PDF on WhatsApp.
That last detail is where most of the damage came from. A PDF cannot be edited, so every change meant re-issuing the whole thing, and there was no way to know who had opened the new one. In practice half the team worked from a version that was already wrong, and the office absorbed the difference in phone calls.
What was actually going wrong
Three problems, and they compounded each other.
SIA licence expiries lived in a second spreadsheet maintained by one person. Twice in a year an officer worked a shift on an expired badge. Both times it was found by the client rather than by Northgate, which is the worst possible way for it to surface — it turns an administrative slip into a question about whether you can be trusted with the contract.
Patrol evidence was a signed paper book left at each site's reception. When a client disputed whether a night patrol had happened, there was nothing to check. Northgate could not prove it had; the client could not prove it had not; and the argument was settled by whoever was more willing to lose the relationship.
Attendance was recorded by officers texting the on-call supervisor. The recorded start time was therefore whenever somebody remembered to send a message, which meant month-end payroll involved reconciling three versions of the same shift.
“The licence rule was the one we argued about internally. It is also the one that fixed the problem, because it stopped being something we had to remember.”
What they changed
The standing contracts were rebuilt as reusable shift patterns — nights, four-on-four-off, and the weekend cover shape used across both shopping centres. A week is now assembled from saved shapes rather than typed from an empty grid.
Licence tracking was set to block scheduling rather than warn. This was the decision that took the longest internally, because it means the system refuses an assignment outright. It is also the one that ended the problem: an officer whose SIA licence has expired cannot be put on a site at all, so the failure mode moved from 'discovered by a client' to 'impossible'.
NFC tags went in at each checkpoint, numbered in patrol order. Officers tap each one as they walk. Two sites also got QR stickers as a backup, since the same token sits behind both.
Check-in became geofenced, with out-of-area attempts flagged for a supervisor rather than refused, because a couple of the construction sites have poor GPS behind hoarding.
The rollout
Northgate imported their officers from the same spreadsheet they had been using, which took one call. The first live rota was built the following week, alongside the spreadsheet rather than instead of it — they ran both for a fortnight before trusting it.
The staff app needed no training. Officers were sent a company code and a temporary password; the two buttons most of them use are check in and check out. The part that needed explaining was not the app but the licence rule, because officers who had let a badge lapse suddenly could not be rostered.
Where they landed
The weekly rota now takes about 45 minutes. Changes reach every phone the moment they are published, and the office stopped fielding calls asking which version was current.
No officer has worked on an expired licence since the blocking rule went on, because the assignment is refused rather than flagged.
Patrol reports go out with the monthly invoice. Three contracts came up for renewal in the first year and all three were retained, in two cases after the client had explicitly asked for proof of patrol coverage — a question Northgate could suddenly answer with a timestamped route instead of a promise.
Payroll preparation dropped from most of a day to about an hour, because the hours came from the door rather than from three reconciled accounts of the same shift.
