Colin Harrison – Managing Director


Colin Harrison is the Managing Director of CIA Fire & Security Ltd. He is responsible for overseeing the finances of the company and the long term plans for the organisation.

Colin is originally from Sapperton, Gloucestershire and attended Gloucester College to study mechanical engineering as an apprentice. In 1965 he began his apprenticeship as an engineer with the Schindler Lift Company.

After his stint with Schindler he took over the mechanical engineering department at Clark Engineering. It was during his time here that he learned the business side of engineering. He had to deal with the finances of the department as well as visit the clients to discuss work.

Colin has over 30 years of experience in the security installation industry. In 1982 he set up Cirencester Intruder Alarms at his home in Cirencester whilst he was working as part of the Harrison and Ball Partnership, a building and maintenance company. He left the partnership in 1994 to focus solely on his intruder alarms company.

The company has been built from the ground up with Colin doing all the surveying and installations by himself until he earned enough money to hire a second engineer. Through hard work and determination he took Cirencester Intruder Alarms from strength to strength, and continued to grow. He recognised the importance of regulation within the industry, Colin set about gaining the ISO9001 Quality Management early on in the company’s development, leading to the NSI Gold certification.

In 2008, Colin rebranded Cirencester Intruder Alarms to CIA Fire & Security Ltd. Soon afterwards he orchestrated the acquisition of A4 Security and Micro-Vision Fire & Security Ltd, alongside Operations Director, Matthew Harrison.

Colin is heavily involved in the local community and charities. He has been on the board of the Bingham Hall Trust for over 10 years, he is currently entering his 10th year with the Cirencester Rotary Club and for the past 10 years he has organised an annual charity golf tournament for Macmillan Cancer Care. In 2014 the tournament raised over £8,500.

In his spare time Colin enjoys playing golf and all forms of motorsport.
