Security services that secure your workplace

More about security services

NSI approved companies provide a wide range of security services including security guarding, door supervision, event stewarding, private investigation, cash and valuables in transit, key holding, CCTV operation, security dog services, close protection and covert services.

Those approved companies operating in the licensable sectors of security guarding, key holding, cash and valuables in transit, door supervision, public space surveillance CCTV and close protection must hold an appropriate SIA licence.

Prior to commencement of a service, your selected NSI approved company will conduct a full site survey in accordance with recognised standards to define your particular security, health and safety requirements.

Assignment instructions for all duties will be formulated in full consultation with you. These will specify the prime objective of deployed security staff clearly linked to your management Policy and strategy. Where a management Policy and strategy does not exist the security objectives will be defined based on an agreed approach to safeguarding your property and assets.

Search the NSI Company Finder or ask your NSI approved company for sight of their unique Certificate of Approval for the specific services for which they are approved by NSI.

Guarding services

Every NSI approved company offering door supervision, cash in transit, key holding, close protection, public space surveillance CCTV and security guarding, must ensure their operatives SIA licenses are up to date.

An operative's SIA licence must be displayed at all times when on duty, so don’t hesitate to ask to see the licence if it is not visible. You can also check here to make sure the individual is on the register of licence holders on the SIA website.
