From Our Website

In 1926 William F. Banham and his wife, Marie-Ann, suffered a series of burglaries at their West London shop. Unable to obtain insurance unless the shop's door was bolted from the inside, necessity prompted William to invent the first ever automatic door bolt. Inspired to help others, William launched his groundbreaking design to the public, with huge success, and Banham Patent Locks was born. Still a family business, we're now the largest security provider in London and the southeast, drawing on our rich heritage to shape our future.


Providing a high quality, personal CCTV monitoring service, our in-house Alarm Receiving Centre operates 24/7, dedicated solely to Banham customers. Always fully-manned, our alarm controllers are ready to dispatch a Key Guard to your property in the case of an emergency or alarm activation. Banham's Alarm Receiving Centre operates 24 hours a day, 365 days a year. It can provide full reporting and a variety of levels of response to security threats, depending on your needs and insurance requirements.
