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 3 to 8

Set per topic. Most topics ask for TRL 4 to 8 at the end of the project; Innovation Actions (pilots and demonstrators) are the largest share.

What you get
grants, up to €30M

Expected EU contribution per project is mostly EUR 4M to 30M (median about EUR 14M); a few large demonstrators reach EUR 90M to 100M. 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.
  • Legal entities established in China are excluded from both research and innovation actions in the batteries destination, and many Innovation Actions exclude entities controlled from China.
  • Some topics add partner requirements, for example a minimum number of manufacturers, grid operators or research centres.

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.
  • Company partners in Innovation Actions get 70%, not 100%. Plan how you fund the remaining 30% before you sign up.

Checked against these official sources on 18 October 2026. Each call can add its own conditions, so confirm in the call document before you apply.
