About Castle Security Group Northern Ltd.

Highlands and Islands, with a strong presence throughout Scotland. With a number of different companies within the group, we provide a diverse range of high-quality services.

We’re a family-owned and run business established in 1992 by current managing director Jim Ferguson. We work with our clients to provide a trusted, professional service and a trouble-free work environment.

As a family business, it’s important to us that we operate with integrity at all times, and that includes treating our employees with respect. We recognise the importance of employee training and provide an open and inclusive working environment.

We employ a high calibre of people to make sure we provide clients with the best possible service, and we provide regular feedback, monitoring and training. We have consultants to assist in specific areas and have a team who specialise in Employment Law and Health and Safety. Many of our employees have backgrounds in the police force and the military.


Our low staff turnover is a testament to how well we look after our staff and this gives clients the reassurance of a happy and committed workforce. We have a workforce who are fully trained and who are fully accredited. Our staff are committed to diligent health and safety practices at all times and our company has an accident free history with no major incidents.

At The Castle Group, we take our corporate and social responsibilities very seriously.
