We are Commtel, proud of who we are & what we do.

Customer elation is our only goal and we seek to always exceed their expectations. We achieve that goal by adopting a team ethos where we all work together using our initiative and a solution based approach.

We will invest in our employees with training and self development programmes so that we all reach our full potential.

What We Do

Our vision is to continue to lead the market in door entry and access control solutions. We cater for domestic, commercial and public sector applications, making entry and exit systems ranging from a simple one button unit to completely bespoke systems which are managing multiple access points, for thousands of visitors . . . and everything in-between!

We pride ourselves on finding the perfect solution for each project. We'd love to see how we can help you!

Our Journey

We were challenged to find a cost effective solution for a small residential area that wanted to retro fit gates and with an intercom system.

In the 1980's, the only option was to dig up the roads and install a hardwired system, making the whole project too complex and expensive.

There was an opportunity to use the technology of the day to find a viable solution, by utilising the existing telephone network and linking it to an access control system. Costs were dramatically reduced and the first Telguard unit was born. With full BABT approval Commtel Limited was incorporated in 1992, selling the Telguard range of products.

Operating in an ever-changing environment, our Research & Development Department keeps us at the forefront of technology.

Our Progress

As a leading British manufacturer of intercoms we have continued to develop innovative solutions to meet the demands of our customers over the last 28 years. From the initial idea back in 1992 for landline based technology, to the launch of our most recent 4G LTE products in 2020, we have always strived to provide the class leading performance and reliability that sets us out from the crowd.
