Looking for a new supplier is always a difficult process; a lot of companies focus on price. Price certainly is important, but there’s more to a supplier than their invoice. Having meaningful accreditations where tough external audits are carried out should certainly be on your list of criteria when it comes to selecting and having confidence in your security systems supplier.

As you can see here, Clarion has an impressive list of external accreditations.


The National Security Inspectorate (NSI) is the specialist approvals and certification body that inspects companies providing home security, business security, and fire safety services. Choosing an NSI approved company ensures that the contractor you select works to the highest recognised industry standards as demanded by the police, fire and rescue services, and insurance industry. Choosing a Gold NSI installer should certainly be a must for a quality service.

ISO 27001

ISO 27001 is an international standard on information security and the latest addition to the Clarion compliance portfolio. This international standard details all requirements for establishing, implementing, maintaining, and continually improving an information security management system. In short, it ensures that Clarion can keep our customer information secure. As the importance of data management increases and over two years on from the implementation of GDPR, Clarion will always strive to stay one step ahead with data management.


CHAS helps all clients and contractors ensure compliance across the different areas of risk management and mitigates risks across supply chain practices. Through this accreditation, the schemes can help businesses achieve compliance, mitigate their supply chain risks, and support efficient supply chain management. Clarion is proud to have held and maintained this accreditation for many years.

Safe Contractor
