30-Day Action Plan

A strategic timeline for applicants with one month until the deadline wave

Week 1: Foundation

Now — 23 March 2026
  • Finalize consortium composition and confirm partner commitments in writing
  • Assign clear roles: coordinator, WP leaders, budget officer, ethics lead
  • Complete Part B outline with section responsibilities and word limits
  • Begin drafting the Excellence section — objectives, methodology overview
  • Register on the Funding & Tenders Portal and start Part A administrative forms

Week 2: Drafting

23 — 30 March 2026
  • Draft the full Excellence section — align methodology with evaluation criteria
  • Prepare budget estimates per partner using EC cost model templates
  • Begin Impact section — expected outcomes, dissemination and exploitation plan
  • Compile CVs and track records for key personnel
  • Check eligibility conditions (country requirements, partnership rules)

Week 3: Refinement

30 March — 6 April 2026
  • Complete Impact section with quantified KPIs and sustainability plan
  • Draft Implementation section — work packages, Gantt chart, milestones, deliverables
  • Internal review round — circulate to all partners for feedback
  • Address AI disclosure requirements (mandatory since 2024)
  • Prepare risk assessment table and ethics self-assessment

Week 4: Finalization

6 — 14/15 April 2026
  • Final editorial review — consistency, language, formatting, page limits
  • Complete ethics self-assessment and attach required ethics documents
  • Finalize Part A administrative forms and budget tables in the portal
  • Upload Part B PDF and verify all attachments in the submission system
  • Submit at least 48 hours before the deadline — allow buffer for technical issues
  • Celebrate and prepare for potential evaluation rebuttal phase

Key Tips for Applicants

Essential guidance to strengthen your Horizon Europe proposal

🤖

AI Disclosure Requirements

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.

Evaluation Criteria Reminder

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.

🤝

Consortium Building

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.

💰

Budget Planning

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.

📋

Two-Stage vs Single-Stage

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.
