About Us

AAA Security was first established by John and Lynn Dorman in Edlesborough in April 1992. John had previously worked and established a creditable reputation in the Security Systems Industry having worked for a National Company over the previous 18 years and Lynn had gained vast business administration and accounting experience having worked for Barclays International for over 13 years.

As a Company, we rapidly gained recognition for quality work in the domestic market. As a result, the bulk of new work arose through recommendations from existing satisfied customers.


NACOSS recognition as an approved installer for intruder alarms was achieved on 7th July 1995, which enabled us to continue a steady increase in domestic installations, but also to successfully develop the commercial customer market. We were then able to install insurance specified systems and take on County Council works.

The Company has gained police approval in Bedfordshire, Hertfordshire, Buckinghamshire, Northamptonshire, Cambridgeshire and the Metropolitan Police area.

Since July 1999 the Company has operated from premises at Office 1, Collec Depot, Billington Road, Leighton Buzzard and has continued to grow rapidly. We are also the only NACOSS approved installer in Leighton Buzzard.

We now offer a vast range of services, from catering for the small domestic burglar alarm system to the large commercial and industrial sites, installing monitored alarm systems, CCTV and Access Control. A system can be designed to suit the customer's needs, be it a school, library, offices or a private dwelling. We also offer a 24-hour maintenance back-up.

The majority of our work is kept to Beds, Herts, Bucks, Northants and the Metropolitan Police area to ensure that we provide an efficient and prompt service. As a NACOSS Approved installer, accredited to ISO 9001:2000 and UKAS Quality Management 0142, a 4-hour response time must be provided, if requested by the customer - a target which we have always been able to reach.

All our engineers and office staff have been security screened, covering a 10-year period before joining the Company. Although all our engineers have had many years experience within the Security Industry, they also continue to receive in-house training, along with attending external courses on new products and procedures within the Industry.

Following our 6-monthly inspection by NACOSS in October 2003, we were awarded NSI NACOSS Gold Approval for the Design, Installation and Maintenance of Electronic Security Systems.
