DBS delivers large scale administration and smaller specialist services to enable the wider MOD to focus on its core aims, maintaining the UK’s Defence and Security.

Our Vision - To support UK defence customers with outstanding service every time.

Our Mission – Together we will proudly support Defence, continuously improving and delivering flexible, timely, sustainable and value for money services that underpin the whole force and enhance operational capability.

This is a non-contractual arrangement where all office-based employees will be expected to spend a minimum of 60% of their working time in office, subject to capacity and any required workplace adjustments. Requirements to attend other locations for official business, or work in another MOD office, will also count towards this level of attendance.

Defence Business Services cannot respond to any questions about working arrangements.
