Banham Patent Locks Ltd was founded in 1926 by William F. Banham and has been protecting property since that date. He invented the first Banham automatic door bolt and became a pioneer in the production of high quality locks. Both the police and insurance industry have praised these locks. Our locks which have a unique registration system are still protected by worldwide patents, hence the word patent in our company name.

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.


Avoid locksmith scams by using a credible expert. Rogue locksmiths operating in London prey on the vulnerability of those who are locked out and charge extravagant prices.

If you need to replace or change your door locks, Banham locksmiths can use their extensive experience and knowledge to make the best recommendations for you and your property.
