We are extremely proud of our client base that includes ‘Blue Chip’ companies, prestigious landowners in London and the Home Counties, and a multitude of commercial and residential properties in London and the South East. We value each and every one of our customers and indeed a lot of work we do is from recommendations and repeat business from satisfied developers.

What sets Century 21 apart from the competition is that we are big enough to be noticed, but small enough to care. An ethic that embodies everything we do.

What We Do

We are a National Security Inspectorate NACOSS Gold, NACOSS Fire Gold & BAFE SP-203 approved company for all elements of design, installation, commissioning and certification of our systems.

In addition to our hard won accreditations we are also approved installers for BT RedCARE, CSL DualCom for Association of Chief Police Officer approved monitoring. It will not therefore surprise you to hear that we are preferred installers for FAAC and CAME, the two main players in the field of automation for gates, barriers and bollards.

The security industry is blighted by small companies and one man bands who tell you they can install a system, but have no accreditation and cannot certificate them for Insurance approval or offer any kind of ongoing maintenance. Moreover we provide 24 hr support to our customers, 365 days a year.  One of our customers has saved £40,000 per year on their Business Insurance by having a certificated fire alarm system.
