UK R&D Spending Decline Raises Questions for Growth Ambitions
Recent analysis has revealed that UK R&D spending has fallen by £2.8 billion in real terms since 2021, sparking concerns over the nation’s long-term growth ambitions. As the government continues to promote innovation-led recovery, this downward trend threatens to undermine competitiveness, productivity, and the ability of UK businesses to commercialise cutting-edge research.
Against this backdrop, advisory firms such as FI Group, specialists in R&D tax incentives and grant funding, are urging companies to act strategically to maintain momentum in innovation.

The Market Context: Why R&D Investment Matters
Globally, research and development is a recognised driver of productivity and competitiveness. According to OECD data, every £1 invested in R&D can generate multiple pounds in economic growth through knowledge transfer, commercialisation, and new business creation.
For the UK, where sectors such as life sciences, aerospace, energy, and digital technology underpin the industrial strategy, sustained investment is essential. Yet recent figures show businesses have scaled back spending in real terms, at a time when other countries, including Germany and the United States, are intensifying their R&D commitments.
Challenges Behind the Decline
Several factors are contributing to the contraction in UK R&D expenditure:
- Inflationary pressures reducing the real value of corporate and public investment.
- Uncertainty around tax incentives, including reforms to the SME scheme and the merged RDEC model.
- Global competition, with firms shifting activity to regions offering more generous incentives.
- Economic headwinds, leading many companies to cut or delay innovation projects.
Without intervention, these challenges could limit the UK’s ability to meet its target of becoming a science and technology superpower by 2030.
Opportunities for Businesses
Despite the decline, opportunities remain for firms willing to be proactive. Businesses can:
- Leverage R&D tax relief under the new merged scheme and the Enhanced R&D Intensive Support (ERIS) for loss-making SMEs.
- Apply for Innovate UK grants such as Smart Grants, Biomedical Catalyst, and the Industrial Energy Transformation Fund.
- Collaborate internationally through Horizon Europe, Eurostars, and other European funding streams, which the UK continues to access.
- Optimise innovation portfolios by balancing long-term research with projects closer to commercialisation.
FI Group’s International Grants Guide 2025 highlights that public-private partnerships and European programmes remain accessible to UK firms, offering significant non-dilutive support for R&D investment.
