Founded in 1974, Lincoln Security Ltd. has proudly served Lincolnshire for over 50 years, growing from a local locksmith into the region’s leading provider of security solutions for homes, businesses, and critical infrastructure.

With a strong foundation in Lincoln and the surrounding areas, we have built a reputation for trusted, high-quality security services, working with homeowners, small businesses, and large organisations to keep communities safe. Our team of local experts provides a full range of physical and electronic security solutions, from key cutting and intruder alarms to access control, CCTV, and security doors—all backed by our dedicated in-house engineers.

We work closely with residents and businesses across Lincolnshire, offering:

Home security solutions, including smart locks, safes, and alarm systems.
Commercial security, such as access control, fire doors, and master key systems.
Emergency locksmith services, ensuring 24/7 support for urgent security needs.
While we remain deeply rooted in Lincolnshire, our expertise has also led us to work nationwide. We provide specialist security solutions for Critical National Infrastructure (CNI), securing water, gas, and electricity providers, as well as government, healthcare, military, and transport sectors. In addition, we support businesses across the UK with high-quality security doors, access control, key management, and perimeter protection solutions—ensuring commercial properties remain secure, compliant, and protected.

As an independent, family-run business, we continue to grow while staying true to our local values. Whether securing a home in Lincoln, a business in Grimsby, a national retailer in Manchester, or a power station in London, our mission remains the same: to provide trusted, high-quality security solutions tailored to every environment.
