BS 8484:2016

BS 8484:2016 is the British Standard for the provision of lone worker device services

NSI Guarding Gold for Lone Worker AlarmsThe standard defines both lone worker devices and Alarm Receiving Centre (ARC) compliance as well as covering aspects such as sound financial grounding, secure data protection, quality training and full audit capability from the supplier of a lone worker solution. BS 5979 is the British Standard specifically relating to the standard of ARCs.

In January 2010, ACPO (Association of Chief Police Officers for England & Wales) published its updated Security Systems Policy to Police forces specifying when and how the Police will respond to a lone worker alarm. It called for lone worker devices to be audited against BS 8484 and for the ARC to conform to Category II of BS 5979. It is impossible to guarantee a Police response to a lone worker system which does not conform to both British standards.

The Policy, now under the guidance of the National Police Chief’s Council, states that the Police will respond to a security system activation either as a result of a confirmed activation through a remotely monitored security system, or where a person at the scene reports an offence in progress and requests police attendance. The installation and services provided by the installing company and an Alarm Receiving Centre (ARC) shall be certified by a United Kingdom Accreditation Service (UKAS) such as NSI.

Full certification enables the highest level of police response.

As SkyguardGuardian24 and Peoplesafe are certified to the British Standards (via NSI’s Gold Scheme) we have the ability to request a priority “Level 1” response from the local Police force, for an emergency alarm anywhere in the UK (where available). This system provides a far quicker response to the lone worker requiring assistance than dialling 999. We are also able to use direct dial numbers for Irish constabularies, in order to provide a local emergency response for alarms raised in the Republic of Ireland.

The benefit to lone workers under our protection? It guarantees a faster response in the event of an emergency and saving precious minutes can make all the difference.

Our ARC became the first in the UK to be certified to the new Lone Worker Monitoring Service standard: BS 8484, which included the highest standard for Alarm Receiving Centres: BS 5979 (Category II).


We're innovators in our sector and have played an instrumental part in developing industry standards for better lone worker protection. Both brands are represented as committee members of the British Security Industry Association’s (BSIA) Lone Worker Section. We advise and work with key industry stakeholders such as the National Police Chief’s Council (NPCC), the British Standards Institute (BSI), and numerous other regulatory bodies.
