Armed Forces Covenant

As proud signatories of the Armed Forces Covenant, Octaga is committed to supporting the Armed Forces community, including serving personnel, veterans, reservists and military families. The Covenant is a national pledge ensuring that those who serve, or have served, are treated fairly and are not disadvantaged because of their service.

Given that much of Octaga’s own leadership and officers have served within the UK Special Forces and wider Armed Forces, this commitment is a natural extension of the company’s heritage. We actively encourage our clients and business partners to consider becoming signatories themselves.
