Conclusion (the committee's words)
The Department acknowledged that providing poor quality accommodation negatively impacts its personnel. Most significantly, it increases the risk that people leave the service earlier than they otherwise would.41 This is a serious risk given the problems with retention that the Department has set out and the length of time it takes to train specialist staff such as engineers.42 37 Q 101 38 C&AG’s report, para 3.27 39 C&AG’s report, para 2.13 40 Q 105 41 Q 107 42 Qq 101, 103 12 The Department also told us that it needs to upgrade accommodation so that staff become more engaged and feel more valued, with the implication that poor accommodation reduces personnel engagement.43

Published 19 January 2026.
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with most of the Committee's recommendations on the F-35, disagreeing on a F-35-specific workforce plan and on updating the Committee on Dual Capable Aircraft costs.
- On Full Operating Capability, the government agrees that criteria should take account of capability gaps and sustainment, with a target implementation date of November 2026.
- It agrees to write to the Committee by 30 April 2026 on increasing F-35 availability, saying the longer timeline is needed to draw on lessons from Carrier Strike Group 25.
- It disagrees with producing an F-35-specific recruitment and retention plan and will instead address the issue through the "ongoing RAF People Campaign".
- On RAF Marham accommodation, it will write by 31 May 2026 to advise "whether" the current timescale can be brought forward, after infrastructure requirements are reassessed following the Defence Investment Plan.
