The rules in full

Where you must be based
the EU or countries associated with Horizon Europe

Any partner in an EU or associated country can coordinate, including the UK, Switzerland, Norway and Israel.

Who can apply
a startup, an SME, a mid-cap, a large company, a university, a research organisation, a public body or a non-profit

Any legal entity can take part, from start-ups to universities. Individuals and teams without a company cannot apply.

Who can join as a partner
a startup, an SME, a mid-cap, a large company, a university, a research organisation, a public body or a non-profit

Partners from other countries can join as associated partners without EU money. Entities in the listed low and middle income countries are also funded.

Alone or with partners
Consortium of at least 3 organisations from 3 countries

At least 3 independent organisations, each in a different country: 1 in an EU Member State and 2 more in EU or associated countries. Affiliates of the same group do not count. Coordination and Support Actions can be a single organisation.

Stage
TRL 2 to 8

Set per topic. Most are Research and Innovation Actions around TRL 2 to 6; Innovation Actions run pilots up to about TRL 8.

What you get
grants, up to €15M

Expected EU contribution per project is mostly EUR 3M to 15M (median about EUR 10M); a few topics reach EUR 38M to 60M. The amount is shared by the whole consortium.

Funding rate
Research and Innovation Actions: 100% of eligible costs. Innovation Actions: 70% for companies, 100% for non-profits. Coordination and Support Actions: 100%. Actual-cost grants add a 25% flat rate for overheads.

Conditions to check

  • Your project must answer one specific open topic in the work programme. Good ideas outside a topic text are ineligible.
  • Some topics change the rules: a few restrict participation to the EU and selected countries, and Innovation Actions in critical technology areas exclude entities controlled from China.
  • About 35 to 40 topics require the multi-actor approach: farmers, foresters, fishers or other end users must help shape the project from the start. Without it the proposal is ineligible.
  • Some international topics need extra partners, for example at least 3 independent entities from African Union member states.
  • Entities controlled from China are excluded from some Innovation Actions.

Where applicants trip up

  • Too few independent partners: three companies from one group, or partners from only two countries, fail the eligibility check.
  • A private coordinator asking for EUR 500,000 or more gets a financial capacity check. A young company with thin accounts may be asked for guarantees or to hand coordination to a stronger partner.
  • A token stakeholder board does not meet the multi-actor condition. Evaluators look for end users with real roles and budget.
