The real risks Utilities, Telecoms & Field Engineering lone workers face

Utilities, Telecoms & Field Engineering staff regularly work alone — in the community, on client sites, or out of hours. These are the hazards your lone working policy must address.

High-Hazard Sites

Working alone in substations, at height on masts, or near live utilities.

Falls from height and electrical incidents are among the leading causes of field injuries.

Public Interference

Aggression from members of the public during street-level works or smart meter installs.

Utility workers report an increase in public-facing threats since 2021.

Isolated Remote Access

Visiting remote infrastructure with poor site-specific security or backup.

Achilles UVDB audits assess suppliers' wider health and safety management systems, which lone working policy and emergency response arrangements form part of.

Your legal duty

Construction (Design and Management) Regs 2015

Where utility and telecom field work falls within CDM 2015's definition of construction work, including much installation, maintenance and repair of fixed electrical, telecoms and similar services, it mandates adequate communication and emergency response systems for all site workers. The Sentry supports the practical steps behind that duty.

Built for the way Utilities, Telecoms & Field Engineering teams work

The whole platform deploys on the smartphones your Utilities, Telecoms & Field Engineering staff already carry — no devices to buy, charge, or replace.

One-touch panic alarm

Instant SOS with live location sent to the duty manager or regional hub.

Automatic video capture

Camera triggers on alarm for cloud-stored witness evidence.

Private incident reporting

Securely report site hazards or near-misses for the H&S audit trail.

The complete platform

Every plan includes the full Sentry feature set

The same two-sided system — staff app plus manager portal — protects your Utilities, Telecoms & Field Engineering teams. No hardware, no IT integration, live in under an hour.

Home-screen widget SOS

Exclusive to The Sentry: fire the alarm, share your location, and start recording straight from a home-screen widget — one touch, without opening the app. In a real emergency, the extra steps simply aren’t there.

Loud or silent panic alarm

One alarm, two modes. Loud mode sounds an audible siren; silent mode is completely discreet for confrontational situations. Both instantly share live location with your managers and Nearby Team.

Automatic video capture

Recording starts the moment an alarm triggers. Unalterable footage is saved to the cloud audit trail, emailed as a view/download link, and kept on the handset. (Loud mode records video only; silent mode also captures audio.)

Lone Worker Timer

Session-based timed check-ins: set your own interval and the app prompts you to check in during a session. If a check-in is missed, help is escalated. Added specifically for the wider lone worker sector.

Fake phone call

Defuse a tense situation with a simulated incoming call that uses your phone’s native ringtone and generates a fresh caller number each time — so it appears entirely genuine.

Live location sharing (user-led)

Real-time GPS — but only during a work session you choose to start. The Sentry never tracks passively or automatically, so your personal time stays private. Privacy by design.

Private incident reporting

A confidential, whistleblowing-aligned channel to report harassment — with the option to submit anonymously. Once sent, no trace is left on the device: no email confirmation, nothing stored locally. Satisfies EHRC Step 4.

Friends & Family licences

Every staff member gets three free personal licences, so their family can use the same safety technology — entirely separate from the employer’s account.

Manager portal — included on every account

  • Live dashboard of all active team sessions — worldwide map, unlimited users visible
  • Configurable incident-report routing per user or branch, with read-receipt tracking
  • Complete encrypted audit trail with unlimited history, plus PDF export of incident reports
  • ERA 2025 compliance documentation pack and downloadable, timestamped audit trails
  • Multi-branch / multi-site structuring on one account, and unlimited manager accounts
