Guard Tour and Scheduling Software for a Security Company in London (2026)

The verdict in three sentences

For a London security company with 1,100 SIA-licensed officers across 180 sites, a custom app for scheduling, guard tours and digital incident logs costs 60,000 to 140,000 GBP in 2026, delivered in 12 to 16 weeks. The issue is not technology but lost billable hours: untracked cover shifts, unproven patrols and overtime disputed by clients. An app that produces proof of presence and feeds invoicing directly pays for itself within months on that line alone.

Why billable hours disappear

In many UK security firms, the rota lives in a spreadsheet, check-calls go to a control room by phone and the occurrence book stays on site. At month end, the billing team rebuilds hours from these sources, and every gap is settled in the client's favour.

QR checkpoints cost almost nothing, but they can be photographed and replayed. NFC tags, around 1 to 3 GBP each, are harder to bypass and suit sensitive sites: banks, data centres, critical infrastructure.

2026 budget: custom or off-the-shelf SaaS

Security workforce platforms are powerful but priced per officer. For 1,100 officers, the subscription quickly rivals the total cost of a custom build. The figures below are 2026 market orders of magnitude.

The custom 3-year total includes maintenance at 15 to 20 % of the build per year and cloud hosting. Hardware is needed in every scenario: across 180 sites, one phone per static post means 27,000 to 54,000 GBP, often spread over 24 months.

What the app contains, module by module

The app must work offline on site and sync when signal returns, which matters in basements and plant rooms. Lone-worker check-ins are often required by clients and insurers. The client portal is frequently the deciding sales argument: a facilities manager who sees patrols in real time renews more easily.

Mini case study

Daniel, operations director of a London security company, manages 1,100 officers across 180 sites. Each officer works about 208 hours a month, or 228,800 hours, billed on average at 21 GBP an hour. He estimates that 1.5 % of hours actually worked are never invoiced, mostly cover shifts.

That is 3,432 hours, about 72,000 GBP of revenue lost each month. With an app at 100,000 GBP, this line alone repays the project in under 2 months of full use, before counting the 5 days of manual invoicing saved. This is an illustrative calculation to redo with your own rates.

FAQ

Will officers actually use an app?

Yes, if the screen is limited to three actions: start shift, scan checkpoint and log incident. A 2-hour session per team is usually enough, and the interface can use icons for officers less comfortable with written English.

Does every officer need a company phone?

No, one phone per static post is enough, handed over at shift change. For 180 sites, plan 180 to 220 devices at 150 to 300 GBP each with rugged cases and a data plan of 8 to 15 GBP per month. Mobile patrol officers can use their own phones under a clear BYOD policy.

How do we prevent checkpoint fraud?

Combine NFC tags, geolocation and timestamps: a scan more than 100 metres from the expected point is flagged to the supervisor. A random selfie at shift start, requested 1 to 2 times a week, limits phone sharing.

Does the app handle payroll?

It prepares variable elements (standard hours, nights, overtime, absences) and exports them to your payroll software. It also checks that pay never falls below the National Living Wage of 12.71 GBP per hour applying from April 2026, and that weekly hours respect opt-outs under the Working Time Regulations.

How long until go-live?

Plan 12 to 16 weeks, including a 2-week pilot on 10 to 15 sites. Rollout to all 180 sites then happens area by area over 3 to 4 weeks.
