About
About 3L Security Services Limited
A specialist provider of safety-critical personnel, security, and cleaning and soft facilities management, based in Richmond and working across London and the South East.
Who we are
3L Security Services Limited provides safety-critical personnel, security officers, and cleaning and soft FM staff. Our services are designed for the demands of high-footfall transport and public environments, where reliability, compliance and a professional frontline matter most.
From our personal experience in security and operations management, we are well set to deliver the contracts we are awarded smoothly and successfully. We have built our company with strong fundamentals and credentials to support and deliver them.
Our vision
To be the specialist supplier that organisations across London and the South East turn to for safety-critical personnel, security and cleaning – known for genuine accountability, rigorous compliance and responsive, senior-led service.
Our mission
To deliver safety-critical personnel, security, cleaning and facilities management services that protect passengers and the public, support operational continuity and uphold the highest standards of integrity – so that every organisation that appoints us can focus on its core purpose with full confidence in its frontline workforce.
We were founded on the belief that transport and public sector infrastructure deserves a supplier built on genuine accountability, rigorous compliance and the responsiveness that a specialist, senior-led company can provide.
Our values
- Safety first, always – from recruitment to the end of every shift, our decisions are grounded in the safety of passengers, the public and our own people.
- Integrity without exception – we vet rigorously, report transparently and act honestly at every level. Being Modern Slavery Compliant is a minimum standard we hold ourselves to.
- Operational excellence – we deliver what we commit to, with consistent, measurable performance from mobilisation to completion.
- Direct accountability – our leadership is personally accountable for every contract. You deal with decision-makers, not intermediaries.
- People-centred growth – our service is only as strong as the people who deliver it. We invest in training our operatives and treat every individual with dignity and respect.
Why 3L
Where larger contractors offer standardised, volume-driven delivery, we offer direct management accountability, responsive mobilisation and service shaped to each contract.
Our leadership is operationally present, not administratively remote. Your concerns go to decision-makers, not call centres, and compliance is never treated as a box-ticking exercise.

- Safety-critical personnel: gateline assistants, customer service assistants and rail replacement bus controllers (station-side)

Leadership
