About STM: About STM

The STM Approach

STM Group (UK) Limited is an award-winning company, providing bespoke manpower service solutions. It specialises in the delivery of high-quality security, cleaning, and customer-focused, services, underpinned and supported by leading edge technology.

Established in 2005, and with offices in London and Manchester (where the Company 24 Hour Control Room is situated), STM has national coverage. The organisation has developed through controlled organic growth, combined with a selective acquisition strategy. The Company prides itself on the quality and flexibility of its service delivery model, with an underlying commitment to proactivity and reliability at the core of its philosophy.

STM is:

Supportive to clients, and each other
– Adhering to a philosophy of Mutual Trust (based around the key principles of Loyalty, Integrity, and Pride).
– Committed to delivering a Proactively Managed Service (to clients and staff alike), and not leaving anything to chance.


The STM focus is on providing consistent, reliable, service delivery, by getting the right people, to the right place, at the right time. A proactive management approach, combined with a robust quality system, will ensure the STM focus is on prevention (as opposed to cure). STM will use a combination of internal customer (staff) development, and technology, to apply a continuous improvement philosophy, adding tangible value wherever possible. STM recognises that each customer is different, and will use its experience to create an individual service strategy to meet specific external customer (client) needs.

STM Mission

To be universally recognised as ‘Best in Class’ in the delivery of specified support services

STM Vision

The STM Vision is the establishment of a true External/Internal Customer Environment – whereby STM clients (external customers) and STM staff (internal customers) are both receiving the highest levels of service, support, and positive engagement ‘from STM as an organisation’.
