“In service, the devices have proved their value time and time again, not least by providing the officers with constant reassurance that, if necessary, they can summon help quickly. That has made their lives much more comfortable and made it a lot easier for them to do their jobs.”
Ian Lockett, Cheshire East Council
“The deciding factors in choosing Peoplesafe came down to the quality of the devices, the competitive pricing and the service as a whole. We would highly recommend the service to others looking for lone worker protection.”
Helen Muddock, Suffolk County Council
“we had one operative who slipped down a staircase outside and the device raised the alarm automatically. He was quite flustered but Peoplesafe contacted him straight away ensuring his welfare which gave him peace of mind.”
Shaun Campbell, Clear-Flow
“We have many links with companies in the local area, so we asked one who they used. They gave us great feedback on Peoplesafe. We looked into them more, saw they met all our needs, trialled their personal safety devices and went from there.”
Rhona Wight, Mackie’s of Scotland

User Stories

Ambulance Required

A user activated her alarm to advise that she wasn’t feeling very well and required an ambulance. The Controller asked relevant questions to ascertain what was going on and offered continuous support and reassurance to the user, even calling the ambulance for a second time to try and get an ETA.

Hotel Guest

A user activated their alarm as there was a guest being verbally aggressive due to an unknown suspect hitting his car in the car park. The guest became so irate that he removed the fire extinguisher from the hotel and took it outside ready to use against someone else’s car. The police were called and the Controller stayed on the line until they arrived on the scene.
