About us
This role can be based at Andover, Lichfield, or Wyton.
Do you want to work on one or the most exciting transformation projects in the public sector?
The Defence Housing Service (DHS) is being created through the Armed Forces Bill to deliver a step-change in housing for the UK’s Armed Forces and their families following the publication of the Defence Housing Strategy on 3 November 2025, which marked the most significant change to Armed Forces housing in over 50 years. DHS will bring a dedicated focus to improving the homes, communities, and lived experience of Service personnel, placing families firmly at the heart of everything it does.
This is one of the most ambitious housing transformation programmes in the UK today. Backed by a £9.2 billion investment, DHS will modernise tens of thousands of homes, introduce a more proactive and customer-focused approach to maintenance, and unlock new opportunities to develop housing on Defence land. DHS will have the focus and agility to deliver change at pace, combining public service values with greater flexibility to build the skills, systems, and partnerships needed for the future.
This is a rare opportunity to be part of shaping its culture, influencing how it works, and helping deliver lasting improvements for Service families across the UK.
The Defence Housing team is currently part of the Defence Infrastructure Organisation (DIO), who respond to the evolving needs of our military personnel, and the ways in which they live, work, train, and deploy. We are proud to be the expert partner Defence needs for all their infrastructure requirements. From large-scale infrastructure projects such as runways for the F35 fighter jets to net carbon-zero accommodation for our Service families, our activities focus relentlessly on our customers, and our outputs are unique in the UK and across the globe!
DIO, What we deliver every day.
The future delivery model for this team is currently under review and may change as part of potential organisational developments. This could include the team or function transferring to a different employer or organisational structure in the future. Should activities transfer out of the Ministry of Defence, existing employees transferring with those activities will maintain the same, or substantially the same, terms and conditions of employment.
About the role
The DHS Lead Scrutineer strengthens investment governance by providing expert business case guidance, independent evidence reviews, and clear recommendations to approving authorities.
