Banham has been a name that the residents and businesses of London have been able to rely on for their individual security needs since 1926, when William F. Banham invented the first ever automatic door bolt. Since then our reputation has grown throughout London, south east England and beyond. From our patent locks, to our state-of-the-art alarms and stunning front doors, we're the premium one-stop shop for our customers' security needs. We're also still family-owned, into our fourth generation and pride ourselves on our family values which are at the heart of everything we do.
