Defence environments, built for readiness and resilience

Defence estates are complex, security-sensitive environments where operational readiness depends on far more than frontline capability alone. From accommodation and training facilities to operational bases, logistics hubs and secure infrastructure, the quality and reliability of support environments directly affects preparedness, morale and mission effectiveness.

Defence organisations must maintain resilient estates that support personnel to train, recover, plan and operate effectively — often across large, ageing and geographically dispersed portfolios. In this context, facilities management is not a background service. It is a critical enabler of readiness, welfare and resilience. Our approach is shaped around the realities of defence operations: disciplined delivery, trusted personnel and services aligned to operational tempo. This is People-First FM applied to Defence — supporting the people who protect the nation through environments that perform when it matters most.

Why ISS in Defence

Defence requires partners who understand that support environments directly influence operational capability, morale and readiness:
  • Understanding of defence environments: ISS supports defence estates with an appreciation of operational tempo, military rhythms and the realities of service life.
  • Trusted, disciplined delivery: our people are trained to operate professionally and reliably within secure, highly regulated environments.
  • People-first support for defence communities: we create environments that improve the lived experience of the personnel who train, live and work across defence estates.
  • Integrated estate support: we combine workplace, accommodation, food, cleaning, technical and project services under one accountable structure.
  • Operational resilience at scale: ISS supports complex, distributed estates where continuity, responsiveness and assurance are critical.

Armed Forces Covenant 

We are proud signatories of the Armed Forces Covenant — a promise to treat those who serve, have served, and their families with the fairness and respect they deserve.

We have demonstrated this commitment since 2015, maintaining Gold status in the Defence Employer Recognition Scheme and renewing our Covenant commitment in July 2024, recognising the valuable contribution that service personnel, veterans and their families make to our business and society.

Our JointForces@ISS programme extends on that commitment into careers, helping service leavers and their spouses transition seamlessly into civilian roles with support tailored to the military community.

Sustainability

Navigating an era of energy volatility

Energy is not just as a fixed overhead, but a strategic variable — one that can be measured, managed, and controlled. We help organisations navigate continued price volatility through three practical levers:

  • Strategic procurement and assurance

  • Disciplined energy management

  • Aligning every operational fix with a credible Net Zero roadmap.

From sub-metering and peak shaving to on-site generation and ESOS-aligned audits, we turn volatility into advantage — cutting costs today while building resilience for tomorrow.
