Horizon Europe Explained: Budget, Pillars, and Who Can Apply

Updated 2026-07-21 · 9 min read

The EU's €93.5bn research and innovation programme, mapped: what sits in each pillar, who may apply, and the consortium rule that decides eligibility before anyone reads your idea.

Horizon Europe is the European Union's research and innovation funding programme for 2021-2027. It is the largest programme of its kind in the world, and it funds everything from single-researcher frontier science to hundred-partner industrial consortia. It is also procedurally strict in ways that disqualify good projects before anyone evaluates the science, which is what this guide is really about.

The budget — and why you'll see two different numbers

Horizon Europe launched with an indicative budget of €95.5 billion. The 2024 mid-term revision of the EU's Multiannual Financial Framework reduced it to €93.5 billion, redeploying roughly €2.1 billion to Ukraine, migration, and the STEP platform. The Commission's own current figure is €93.5 billion.

You will still find €95.5 billion on live EU pages, including some Commission agency sites that were never updated. Both numbers have a legitimate origin; €93.5 billion is the current one. Note that the Commission qualifies it as "indicative" — the figure that binds is the budget stated in the call you're applying to.

The 2026-2027 work programme, adopted 11 December 2025 and worth roughly €14 billion, is explicitly the last work programme of the 2021-2027 period. Call-level budgets and deadlines can be amended mid-cycle, so the Funding & Tenders Portal is always the authority over any summary, including this one.

The three pillars

Horizon Europe is organised into three pillars plus a cross-cutting part. Knowing which pillar your work belongs to tells you most of what you need about competition, consortium size, and funding rate.

• Pillar I — Excellent Science. The European Research Council (ERC) for frontier research led by a single principal investigator; Marie Skłodowska-Curie Actions (MSCA) for researcher training and mobility; and research infrastructures.
• Pillar II — Global Challenges and European Industrial Competitiveness. Six thematic clusters, plus the non-nuclear direct actions of the Joint Research Centre. This is the largest pillar and where most collaborative consortium calls live.
• Pillar III — Innovative Europe. The European Innovation Council (EIC) for breakthrough and scale-up innovation; European innovation ecosystems; and the European Institute of Innovation and Technology (EIT).

The six Pillar II clusters are numbered 1 to 6: Health; Culture, Creativity and Inclusive Society; Civil Security for Society; Digital, Industry and Space; Climate, Energy and Mobility; and Food, Bioeconomy, Natural Resources, Agriculture and Environment.

Alongside the pillars sits a separate Part, "Widening participation and strengthening the European Research Area". It is a Part, not a fourth pillar — it underpins the whole programme, and it carries instruments such as Twinning, Hop-On, ERA Fellowships and Excellence Hubs aimed at countries with lower participation rates.

Missions and European Partnerships are not pillars either. Missions are programmed inside Pillar II and capped at 10% of its annual budget; partnerships are an implementation route that cuts across parts of the programme. Any source describing four pillars for 2021-2027 has this wrong — though a source describing the proposed 2028-2034 successor may legitimately say four.

Who can apply, and the rule that decides it

For standard collaborative calls in Pillar II, eligibility turns on one paragraph. The consortium must include, as beneficiaries, three legal entities independent from each other, each established in a different country, such that at least one is established in an EU Member State, and at least two others are each established in different Member States or Associated Countries.

Three things about that sentence catch people out. The independence requirement is mutual — three entities that are all part of one group do not qualify. Affiliated entities do not count toward the minimum. And the countries may be Associated Countries, not only Member States, so a consortium of a German, Norwegian and UK partner is fine, provided the Member State anchor is there.

Several scheme families are exempt from the three-partner minimum and can be single-applicant: ERC frontier research, EIC actions including the Accelerator, MSCA training and mobility, and programme co-fund actions, each of which still requires establishment in a Member State or Associated Country. Coordination and Support Actions are exempt more broadly, and may in exceptional cases involve an entity established in another third country.

Public procurement schemes run the other way and are stricter, not looser: pre-commercial procurement and public procurement of innovative solutions require three independent beneficiaries of which at least two must be independent public procurers established in different Member States or Associated Countries.

Association: where the UK and Switzerland stand in 2026

This is the single most out-of-date claim in guides written before 2025, so it is worth stating carefully from the Commission's own list of participating countries.

• The United Kingdom is associated to the entire programme with the sole exception of the EIC Fund, for award procedures implementing the Union budget from 2024 onwards, with transitional arrangements for the EIC Fund from budget year 2026. The UK is not associated to Euratom.
• Switzerland is associated to the entire programme for award procedures implementing the Union budget from 2025 onwards, and is also associated to Euratom.
• There are 22 associated countries in total, and the list changes — check the Commission's participating-countries document rather than any secondary summary.

Association is not the same thing as unrestricted access. Individual calls may carry participation restrictions on strategic-autonomy grounds — some space and security topics do — and those operate through a separate mechanism from association status. New for the 2026-2027 work programme, entities established in China are ineligible for Innovation Actions and, unless a topic says otherwise, for Research and Innovation Actions, with named exemptions in some clusters and missions.

What happens after 2027

The Commission proposed a successor programme on 16 July 2025 covering 2028-2034, with a proposed budget of €175 billion. It is still called Horizon Europe; "FP10" is community shorthand rather than an official name. As of mid-2026 it is mid-procedure — the Council agreed a partial general approach in June 2026 and trilogues had not concluded.

For anyone applying now, this changes nothing. Calls published under the 2026-2027 work programme run on current rules, and a grant awarded under them is governed by those rules for its full duration.

How GrantsFeed fits in

GrantsFeed tracks open Horizon Europe calls from the EU Funding & Tenders Portal alongside grants and tenders from the US, UK and Australia, normalised into one searchable shape with free email alerts when new calls match your sector. Every listing links back to the official topic page, which is always the authority for eligibility, budget and deadline.
