OBR deems defence spend ‘necessary’

Homeland March 6, 2026

The Office for Budget Responsibility (OBR) has designated an increase in United Kingdom defence spending as a fiscal necessity within its Spring Forecast 2026.

This assessment, delivered alongside the Chancellor’s Spring Statement on 4 March 2026, marks a pivotal shift in the nation’s economic planning, acknowledging that the current geopolitical climate requires a more robust and sustained financial commitment to national security. The OBR’s report indicates that the previous spending trajectory must be adjusted to ensure the UK can meet its NATO obligations and maintain a credible deterrent, with a clear path now established toward reaching a target of 2.5% of Gross Domestic Product (GDP) by the end of the decade.

For businesses operating within the UK defence supply chain, this declaration provides a critical signal of long-term demand and fiscal stability. The OBR highlights that the additional funding is essential not only for the procurement of front-line equipment but also for the revitalisation of the domestic industrial base. This policy shift is expected to accelerate investment in major sovereign programmes, including the Global Combat Air Programme (GCAP) and the ongoing delivery of the Dreadnought-class submarines. Prime contractors and sub-contractors are likely to see increased opportunities for multi-year contracts, which are vital for securing the private capital necessary for facility upgrades and workforce expansion.

The Spring Forecast further emphasises the government’s strategic intent to utilise defence expenditure as a primary driver of regional economic growth. By prioritising domestic manufacturing – as seen in recent heavy engineering contracts within the Midlands and the North of England – the Ministry of Defence (MOD) aims to ensure that increased spending yields tangible benefits for local economies. This approach focuses on high-value manufacturing, research and development, and the protection of safety-critical supply chains. For SMEs and specialised engineering firms, the OBR’s findings suggest a more predictable procurement pipeline, enabling better long-term planning for innovation and skills development.

The 2026 forecast also notes that the MOD will continue to reform its procurement processes to maximise the impact of this increased budget. This includes a greater emphasis on social value, exportability, and the rapid integration of emerging technologies. As the UK moves toward this higher spending threshold, the emphasis for the industry will remain on delivering value for money and maintaining the agility required to respond to rapid technological advancements. This fiscal update provides a foundational level of certainty for the defence sector, ensuring that the UK remains a competitive and capable leader in global security through 2030 and beyond.
