If you are a UK deep tech founder chasing serious non-dilutive capital, there's a good chance you've already run into this wall.
We wrote about Horizon Europe funding for UK startups back in June, where we focused on the grant side: the EIC Accelerator grant of up to €2.5m, no strings, no equity given up.
What we didn't say then is that the grant is only half the programme, and it's the smaller half.
The European Innovation Council Accelerator hands out that €2.5m in non-dilutive funding to deep tech startups across the board. For companies in the EU or a Horizon Europe-associated country, that's only the start. On top of the EIC Accelerator grant, the EIC Fund can invest another €0.5m to €10m in equity, and up to €30m through its STEP Scale-Up route. In the most recent funding round, 61 companies split €467m between them, and 85% of them walked away with both grant and equity together as blended finance.

British companies got none of that second part.
Why UK Founders Still Miss the Equity
Since the UK left the EU, EIC Accelerator UK eligibility has meant entities based here qualify only for the grant-only track. The loan and equity components of the EIC Fund have been closed to them.
When the UK formally associated with Horizon Europe again in January 2024, that exclusion was carried over as one of the only carve-outs in an otherwise full return to the programme. The reason wasn't really about research policy at all. It came down to the UK's decision not to take part in the EU's underlying financial instruments - the mechanism the EIC Fund is built on.
We think it's worth sitting with what that's actually cost British founders. This isn't non-dilutive funding being withheld. It's patient capital, high-conviction equity for exactly the kind of capital-intensive, high-risk deep tech that private investors won't touch early — quantum, advanced materials, novel semiconductors, synthetic biology.It's the same scale-up capital gap the British Business Bank has spent the last nine months scrambling to fill domestically, more than doubling its own direct equity investing to reach £400m a year.
The EIC Fund, across the EU and its associated countries, is playing at a materially larger scale, with equity tickets averaging around €3.72m per company and headroom running up to €30m for the biggest scale-ups.
The Workaround Some Founders Have Already Chosen
There has been a workaround, of sorts, as some UK founders have relocated or incorporated a subsidiary in an EU or associated country specifically to qualify for the equity route. That's a real decision founders have made, not a hypothetical, and it's exactly the kind of "stay and scale" leakage that the British Business Bank says its own strategy is meant to prevent.
The Door Might Be Opening. It Isn't Open Yet.
Now here's the part that surprised us. The EU's own research and innovation directorate now states that transitional arrangements are in place for award procedures from 2026 onwards, treating UK-based entities as though they were established in an associated country for the purposes of the EIC Fund - a shift in EIC Accelerator UK eligibility that also covers the new Scaleup Europe Fund, the €5bn deep tech vehicle due to launch this year.
That sounds like the door opening. It isn't quite.
The same guidance is explicit that any actual investment decisions remain conditional on a formal amendment to the UK's association agreement, one that would need to extend that association to specifically include the EIC Fund.
As things stand in July 2026, no such amendment has been finalised. Several EIC-focused advisory services are still telling UK founders, in the plainest terms, that EIC Accelerator UK eligibility remains grant-only.
So we have two things true at once. Officially, EIC Accelerator UK eligibility for the equity mechanism now exists on paper, for 2026 award procedures onwards.
Practically, nothing has changed yet for a founder deciding today whether to build their next round around a UK entity or a European one.
We'd flag this as one to watch rather than one that's settled. If the amendment does land, it would hand UK deep tech founders access to a funding instrument several times the size of anything currently available domestically, without needing to touch a British institution to get it. If it doesn't, the current gap continues to quietly push some of Britain's most capital-hungry, hardest-to-fund companies to root themselves in the EU instead.
What we don't know yet is how many founders have already relocated or incorporated abroad to get around this gap and whether they'd come back even if the barrier lifts.
