Notes to editors:

Croma Security Solutions is an expanding technology led security solutions provider with over 50 years of specialist experience, delivering high-quality security solutions across locksmith, fire and security services for both domestic and commercial environments. The Group's network currently stands at 17 security centres, stretching from its headquarters in Southampton, across the Midlands and up to the Northwest. Croma services a range of sectors including health, education, leisure and entertainment, and utilities, and is trusted by national brands, including multiple NHS Trusts, with their complex security needs.

Croma's growth strategy is focused on establishing a national security network. In 2023, it sold its man-guarding business Vigilant for £6.5m, which has provided the capital to fund the expansion of the business. Croma is a proven acquirer of local, traditional locksmith businesses, which are developed into its network of modern security centres, offering both total security solutions and locksmith services to retail and commercial customers. The new security centres benefit from extended product ranges, centralised group services, and both a local and national customer base. Since the sale in 2023, Croma has added new businesses to its network, and has a strong pipeline of further locksmiths stores to be acquired into the network.

Croma is listed on the AIM market of the London Stock Exchange. Founded in 1970, it is headquartered in Southampton and has over 95 employees.
