Essential guidance to strengthen your Horizon Europe proposal
Since 2024, Horizon Europe requires disclosure of AI use in proposal writing. Include a clear statement in Part B about any generative AI tools used, their purpose, and how outputs were verified. See the EC Living Guidelines on Responsible Use of Generative AI.
For RIA and IA proposals, the standard evaluation weighting is: Excellence (typically 50%), Impact (30%), Implementation (20%). Each criterion is scored 0–5. Minimum threshold is 4/5 for Excellence and 3/5 for the other two. Align your writing to these weights.
Most RIA/IA calls require minimum 3 independent legal entities from 3 different EU Member States or Associated Countries. Prioritize complementary expertise over geography. Check Partner Search on the EC portal.
Typical RIA funding rate is 100% of eligible costs. IA funding rate is 70% (100% for non-profit entities). Use direct personnel costs + 25% flat rate for indirect costs. Budget should match the ambition described in the proposal.
For two-stage calls in CL5/CL6, the April deadline is for short proposals (~10 pages). Focus on concept, novelty, and consortium rationale. Full proposals are only invited for Stage 2 (typically October). Don't over-elaborate — concise impact statements win.
Leverage Horizon Results Platform, CORDIS, and NCP networks to find experienced partners. Also check enterprise.europe.network for SME partners.
