Over half of UK businesses expect positive impact from defence investment but leaders call for targeted support

Research from the Barclays Business Prosperity Index reveals:

• 74 per cent of UK businesses support the Government's plan to raise defence spending to five per cent of GDP by 2035
• 60 per cent believe Government investment in defence can create economic opportunities in their sector
• Over half (51 per cent) expect increased defence spending to have a positive impact on their business, and 56 per cent anticipate benefits for their region
• There is appetite for Government support: 38 per cent say a Defence Guarantee Scheme would encourage them to enter the supply chain, and 34 per cent want improved access to sector-specific skills and training

The Barclays Business Prosperity Index¹, which includes a survey of 1,000 business leaders across a range of sectors, shows strong support for the Government's increased defence spending (74 per cent). This sentiment is consistent across business sizes and regions, reflecting a broad consensus that defence sector investment is both necessary and potentially beneficial for the wider economy.

Of those surveyed, 24 per cent have been involved in defence contracts or supply chains on one occasion, 17 per cent on multiple occasions and 25 per cent have never been but are interested in future opportunities.

Among those expecting a positive impact, 56 per cent see boosting research and development in new technologies as the main benefit to their business. Half (50 per cent) highlight the creation of new contracts and opportunities within local supply chains as a key benefit, while 53 per cent anticipate enhanced skills and workforce development.

More broadly, 51 per cent believe defence spending will attract new investment or partnerships to their region, and 40 per cent expect it to support SME growth, innovation, and job creation locally.

Yet despite optimism, a third of businesses (32 per cent) said they require simplification of regulatory requirements, such as compliance reporting, clearer guidance on the procurement process (33 per cent) and a trusted supplier white list to streamline due diligence (30 per cent).

Half now more positive about working with Defence sector

Business leader sentiment for the sector's ESG risks is nuanced. Close to half (45 per cent) of businesses report increased caution for the ESG risks of working with the sector, while 20 per cent note decreased ESG concerns and greater openness to defence, with almost a third (32 per cent) reporting no change.

This broadly mirrors the sentiment of their business' customers, with 43 per cent indicating heightened customer ESG caution, yet 21 per cent seeing growing openness.

Despite ESG caution, over half (53 per cent) are now more positive about working with the defence sector, compared to only three per cent who have formed a more negative view over the past 12 months.

Leaders call for further support to enter supply chain

To unlock the full potential of defence-driven growth, business leaders are calling for:

• Improved access to sector-specific skills and training (34 per cent)
• Greater transparency around ESG expectations and reputational safeguards (34 per cent)
• Financial incentives or support schemes (34 per cent)

Almost four in 10 (38 per cent) say a Defence Guarantee Scheme, where the government would offer financial guarantees for capital and investment, would encourage them to enter the supply chain.

The findings from the Barclays Business Prosperity Index defence research will be featured at the Department for Business and Trade's Global Space Finance Summit on Wednesday 10 December 2025, which brings together senior policymakers, including Lord Stockwood, Minister for Investment, and experts from across the defence sector.

Matt Hammerstein, CEO of Barclays UK Corporate Bank said: "Our research shows that businesses are increasingly interested in supporting the defence sector, with many ready to innovate and enter supply chains.

"To unlock the full potential of defence-driven growth, we urge the Government to sustain momentum on defence investment by streamlining export and compliance regulations and providing targeted support such as a Defence Guarantee Scheme. These steps will help more UK businesses seize the opportunities presented by increased defence investment.

"At Barclays, we're committed to supporting the sector and helping firms unlock new opportunities to drive innovation and growth across the UK, whilst providing a range of financial products and services to UK, US and European defence companies that supply NATO and its allies."

Abdul Qureshi, Managing Director of Barclays Business Banking said: "Increased defence spending presents a significant opportunity for SMEs to innovate and grow, particularly those in frontier tech.

"Many high potential start ups and scale ups are eager to participate with corporates and enter the supply chain - and these businesses have a vital role in driving regional growth. We're committed to helping businesses seize new opportunities and support their investment plans through tailored solutions and the Business Prosperity Fund."
