Our story

A different kind of FM company.

CSSG UK was founded to give organisations a genuinely integrated facilities partner — one that brings cleaning, security, maintenance and engineering under a single, accountable contract.

Over the years we've grown by doing the basics brilliantly: showing up, communicating clearly, and treating every team member as the face of your brand. The result is long-term partnerships, not just contracts.

  • One accountable contract
  • Named account managers
  • DBS-checked operatives
  • Live KPI dashboards
