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.
