The UK’s Defence Investment Plan was expected this week. It still isn’t here.
Originally due in Autumn 2025, the plan has now been pushed back repeatedly, with the latest commitment being publication before the NATO summit in July. Prime Minister Starmer has described this as a firm, final deadline. We’ve heard that before.
While the headlines focus on procurement programmes, military capabilities and a funding gap estimated at up to £18 billion, there’s a quieter consequence that isn’t getting enough attention: the finance and accounting professionals sitting behind every major investment decision.
Uncertainty halts not only programs but also people’s decisions
Across the defence sector, we’re hearing the same thing from clients. Hiring plans are being reviewed. Budgets are being reassessed. Growth strategies are on hold. Without knowing which programmes will receive funding or when, organisations are reluctant to commit to the teams they know they’ll eventually need. This is exactly when specialist finance recruitment and focused defence finance recruitment strategies should be maintained, not paused.
You can’t build a finance function overnight.
Finance Business Partners, Management Accountants, Tax Specialists and commercial finance leads are not interchangeable hires. These are specialists. Finding them, securing them and on-boarding them properly takes time, time that disappears quickly once investment decisions are made and programmes start moving. The Defence Investment Plan will sharpen timelines further.
The cost of waiting
When the Defence Investment Plan does land, organisations will move fast. Demand for defence finance talent will spike. The talent pool won’t suddenly be larger. As the UK defence investment plan unfolds, competition will intensify.
We’ve seen this pattern before. Delayed decisions compress hiring timelines, intensify competition for experienced professionals and push salaries up. The businesses that stay engaged with the talent market during periods of uncertainty are consistently the ones that hire fastest, and best, when it matters. Keeping defence finance recruitment pipelines warm, and investing in specialist finance recruitment, is the practical way to mitigate risk.
Meanwhile, existing finance teams are already feeling the strain. Managing multiple planning scenarios, supporting forecasting exercises and providing strategic guidance to leadership, all while recruitment decisions remain in limbo, places real pressure on people. In a market where experienced professionals have options, that’s a retention risk worth taking seriously. Clear communication about the anticipated defence investment plan release date can help maintain confidence.
Our view
At Sheridan Maine, we work with defence finance teams at exactly these inflection points. The organisations navigating this period best aren’t waiting for the DIP to drop before thinking about their people. They’re having those conversations now, mapping their talent needs, understanding the market and positioning themselves to move quickly when clarity arrives.
Align your specialist finance recruitment plans and defence finance recruitment activity now so you can act decisively when the UK defence investment plan is published.
The Defence Investment Plan will come. The question is whether your organisation will be ready.
