Alone in a chamber or substation
An engineer works down a chamber or inside a remote substation — around live systems, in a confined space, with no colleague within earshot if something goes wrong.

Utilities & Field Teams
Lone worker protection for utilities and field engineering teams.
Water, gas, power and telecoms engineers, meter readers and field technicians spend their days at remote sites, down chambers and out on rural rounds — often where phone signal is patchy and the nearest colleague is miles away. Not A Lone Worker keeps track of every job so a missed check-in in the middle of nowhere gets noticed straight away.
Where it goes wrong
The risks of working the field alone
Distance, poor signal and out-of-hours callouts are what make field engineering a lone-worker risk. These are the situations UK utilities teams plan for.
A rural round with no signal
A meter reader or field tech covers a scattered rural round where the phone drops to no bars for long stretches — so no one can easily reach them, or know if they’ve moved on.
An overnight fault callout
A technician is called out on their own to a fault in the middle of the night. The depot’s closed, the office has gone home, and no one is actively expecting them to report back.
An injury miles from anywhere
A field worker slips, is hurt, or their van breaks down on a remote stretch. They may be able to raise the alarm — or they may need the system to notice for them.
How NALW fits
Cover that works out in the field
Each of those maps to something the platform already does — and because it fails safe, patchy signal counts against being safe, not for it.
Scheduled check-ins around each job
Alone in a chamber or substation: a check-in timed for when a job should be done means an engineer who doesn’t resurface is quickly missed. A grace window and nudge come first, then escalation — so a quiet confined space doesn’t stay quiet unnoticed.
Fails safe when signal drops
A rural round with no signal: the system treats no clear “I’m safe” as a reason to worry, not to assume the best. If a check can’t be answered because a worker’s out of coverage and stays out, it escalates rather than quietly ignoring it.
Shifts that escalate when overdue
An overnight fault callout: the technician clocks on with START and an expected finish. Run past it with no DONE and it flags overdue and raises the escalation ladder on its own — no one has to be watching the depot phone.
Panic/SOS with last-known location
An injury miles from anywhere: a one-tap SOS — or a texted HELP — sends an alert with the worker’s last-known location, so a mate or manager knows the last spot the engineer confirmed themselves, even out on a remote patch.

The features that matter most for field teams
Automated Check-Ins
Checks timed around each job by SMS, email or the no-install link — and they fail safe when a reply can’t get through.
See check-insShifts & Locations
Clock callouts on and off by text; overdue jobs auto-escalate, and you can see each worker’s last-known position.

A one-tap alarm and HELP keyword for an injury or hazard in the field — instant alert with last-known location.

What it looks like out on the network
Illustrative scenario
Picture a field team spread across a regional patch. Each engineer texts START with an expected finish as they reach a job, and the coordinator can see on the Locations map where each one last checked in safe — nothing more, no live trail down the roads.
One engineer heads down a chamber in a dead spot and the job overruns. The shift flags overdue, the check-in can’t be answered from underground, and Zoe’s call goes unanswered — so the escalation ladder reaches a supervisor with the engineer’s last-known location, instead of the silence being put down to “no signal” and left until morning.
This is an illustration of how the pieces fit together, not a real client story — but every step in it is something the platform does today.
