About Us

Our History

Guardian is a long established specialist security and fire business. We have been trading, uninterrupted for over 25 years, installing and maintaining security and fire systems throughout the South East.

A lot has changed at Guardian since its early foundation. We now offer the benefits of a substantial, mobile engineering work force supported by an experienced, senior management team (Click here to meet the team). We deliver a broad range of security services across our customer base and have installed over 8000 systems.

NSI Gold

In 2006 Guardian achieved the National Security Inspectorate’s Gold level accreditation, which is the highest within the Security Industry. This confirms our status as a premium supplier and reflects the quality and reliability of our staff and processes.

NSI Gold status also entitles us to work closely with all Police and Fire services and a broad range of governmental and educational services as well as commercial customers.

As part of our growth, we have also undertaken selective acquisitions. The resulting increased scale has improved our geographical coverage for customers.
