Post-Brexit R&D: Are UK Startups Thriving or Surviving?

Funding realities in a new era

Since the UK officially left the European Union, its innovation ecosystem has faced a critical question: can it still SlNYqf1vpL in R&D without EU backing?

Prior to Brexit, UK startups benefited immensely from European Union funding programmes such as Horizon 2020, which injected billions into research and development initiatives. But now, with formal ties severed, British startups are navigating a new economic terrain where alternative funding must fill the gap.

In 2025, the reality is becoming increasingly clear: some startups are adapting — even thriving — while others are grappling with uncertainty and delays in both public and private support. The government’s post-Brexit substitute, Horizon Europe association and the UK’s Pioneer programme, are trying to bridge the funding chasm. But are they enough?

Funding the Future: What’s Replaced Horizon?

In 2023, the UK struck a deal to rejoin the EU’s Horizon Europe programme as an associate member. While this move was welcomed by universities and researchers, small startups found themselves tangled in the bureaucracy of transitioning from EU-funded projects to domestic schemes.

“Our research team lost six months of momentum waiting for a funding decision post-Brexit,” says a biotech founder in Oxford. “That delay nearly killed our runway.”

The British government responded with the Pioneer programme and Innovate UK support, offering grants and incentives to plug the holes. However, uptake has been slow, partly due to a lack of clarity and partly due to limited access to mentoring and global collaboration opportunities.

The Angel Investor Shift

Beyond government schemes, private capital has responded with cautious optimism. Angel investors and VC firms are still active but now apply far more scrutiny to R&D-heavy ventures. Startups in AI, green tech, and health innovation have seen consistent interest, while those in early-stage fundamental research are struggling to gain traction.

Interesting fact:

• The UK had the third-highest number of Horizon 2020 projects before Brexit, trailing only Germany and France.
• After Brexit, applications to UKRI grant schemes increased by over 28%, creating backlogs and slower decision timelines.

Thriving in Adversity: Case Studies from the Ground

Not all startups are merely surviving. In Cambridge, a cleantech startup pivoted quickly by establishing a small branch office in Amsterdam, allowing them to maintain EU collaboration while tapping into UK grants. In Edinburgh, a fintech firm doubled its R&D budget thanks to a strategic partnership with a Singaporean investor interested in post-Brexit UK innovation.

This adaptability is key. British startups that think globally, act lean, and diversify their funding sources are showing the greatest resilience.

Where to Next?

As the UK charts its independent future, there’s cautious hope that the R&D space can stabilise. The long-term success of post-Brexit innovation will depend on several factors: clarity in funding pathways, stronger global partnerships, and a more agile support system for small and mid-sized ventures.

In many ways, the question is no longer just about surviving — it’s about reimagining what British innovation can look like when unshackled from legacy systems but still tied to a global landscape.
