BS 8484:2022 certification is held by suppliers of lone worker services, audited by an independent certification body. Employers do not get certified; they buy audited services, and they need to when their risk assessment calls for a monitored alarm with a police response behind it.
Who holds the certification
The audit applies to the companies that provide lone worker devices, apps and alarm monitoring, and it covers their organisation, their alert products and their monitoring arrangements together; the detail is on the main BS 8484:2022 guide. A supplier's accreditation applies to the specific services audited, which is why the directory records scope, not just names. Employers sometimes ask how to "become BS 8484 compliant" themselves. The honest answer is that they cannot, and do not need to: an employer's compliance obligations are the legal duties, and buying an audited service is one of the controls that meets them.
Which employers need it
Any organisation whose people match the risk profiles where an emergency is credible. In practice the standard shows up wherever these roles do:
| Sector | Typical lone working roles |
|---|---|
| Health and social care | Community nurses, health visitors, social workers, home carers |
| Housing and local government | Housing officers, environmental health, enforcement, repairs teams |
| Utilities, construction and engineering | Field engineers, meter readers, site inspectors, surveyors |
| Transport and logistics | Delivery drivers, warehouse staff on single-staffed shifts |
| Retail, security and facilities | Single-staffed shops and petrol stations, security patrols, cleaners |
Public sector buyers lead the pattern because their tenders usually name the standard outright. Private employers follow for the same underlying reason: the response.
Why accreditation matters to employers
Three consequences, in descending order of importance. First, response: only an audited service carries the unique reference numbers that let its alarm receiving centre request a fast-tracked Level 1 police response. Second, evidence: after an incident, an employer who bought an audited service can show due diligence in one line, because the audit already examined the supplier's finances, screening and monitoring. Third, procurement efficiency: requiring the standard collapses a long due diligence questionnaire into a certificate check. None of this makes an unaudited alarm illegal. It makes it slower and harder to defend.
When an unaudited service is defensible
If the risk assessment genuinely finds no credible emergency scenario, and lone working controls exist for check-in discipline rather than response, a simpler unaudited arrangement can be proportionate. The test is honesty about the assessment. An employer who chooses the cheaper tier should be able to point at the assessment line that justifies it, because that is precisely the line an investigator would read back to them.
How to check a supplier's accreditation
Ask for the certificate and check three things: the certification body (BSI, NSI or SSAIB), the edition (it should say BS 8484:2022), and the scope (which of the device, the app and the monitoring it covers). Certification bodies maintain public registers where certificates can be verified directly. The suppliers we have verified, with their scope, are listed in the accredited companies directory.
