About Us

Welwyn Garden Alarms Limited established in 1985 is the largest and longest standing company in the group.

Welgard Fire and Security Systems Ltd was created to offer a non-geographical brand to enable us to be well received in a larger marketplace.

Sentry Alarms Security Systems Ltd has a similar history and local standing as Welwyn Garden Alarms. Sentry was acquired in 2019 by Welwyn Garden Alarms. This has further strengthened the position of both companies in the local area, increasing our engineering capability and broadening our client base in Potters Bar, North London and Hertfordshire.

We are an NSI (NACOSS) Gold security installer and BAFE Approved fire company.

Our ethos across the 3 businesses and objective throughout our years of trading is to provide high quality reliable systems with a dedication to customer service. We have a determination to be at the forefront of technology and in providing cutting edge solutions.

Driven by our reputation, most of our business leads come from recommendations from existing satisfied clients. We are proud of our reputation and continually strive to meet the demands of our clients through an active customer care program where any feedback is gratefully received.

Our offices are Located on the grounds of Hatfield House in Hertfordshire. Although our humble beginnings and preceding 18 years of trading were born out of two earlier premises in Welwyn Garden City (hence the name) if you would like to visit us to view equipment, receive a demonstration or discuss system requirements we will be only too happy to accommodate you.
