How to apply

The standard EU funding process. Each Interreg (European Territorial Cooperation) call publishes its own detailed requirements.

  1. 1

    Find open calls that match your profile

    Search by country, sector, applicant type, and deadline. EU funding is published across dozens of portals, so consolidation saves significant time.

  2. 2

    Check eligibility before investing effort

    Review applicant mode (single vs consortium), entity type requirements, geographic restrictions, and co-financing obligations. Disqualify early to protect team bandwidth.

  3. 3

    Build your consortium if required

    Many Horizon Europe calls require partners from multiple EU countries. Identify complementary organisations early — consortium formation often takes longer than proposal writing.

  4. 4

    Write and submit your proposal

    Follow the call documentation precisely. Most EU proposals require a work plan, budget breakdown, impact statement, and consortium description. Submit via the Funding & Tenders Portal.

  5. 5

    Evaluation and grant agreement

    Proposals are evaluated by independent experts against published criteria. Successful applicants negotiate a grant agreement that defines deliverables, reporting, and payment schedule.

Common questions

What does Interreg fund?

Interreg funds cooperation projects between organisations from different EU countries (and some non-EU neighbours) tackling shared challenges: regional innovation, environment, climate adaptation, mobility, social inclusion, and governance. Themes mirror the broader cohesion policy objectives, applied across borders.

What are the four strands of Interreg?

Strand A is cross-border cooperation between adjacent regions (e.g. France-Germany). Strand B is transnational cooperation across larger areas (e.g. Baltic Sea, Mediterranean). Strand C is interregional cooperation across the whole EU (Interreg Europe, URBACT, INTERACT, ESPON). Strand D covers outermost regions.

Who can apply for Interreg funding?

Public bodies, regional and local authorities, universities, research centres, NGOs, and SMEs based in eligible regions can apply. Each programme defines its own eligible territory. Most calls require partners from at least two or three different countries within the programme area.

How much can an Interreg project receive?

Typical project budgets range from €1M to €5M total, with EU co-funding rates of 80% for less-developed regions and 60–65% for more-developed regions. Larger strategic projects, particularly in transnational programmes, can exceed €10M per consortium.

Where do I find Interreg calls?

Each Interreg programme runs its own website with its own call schedule. The interreg.eu portal lists all programmes by strand and territory. The Funding & Tenders Portal does not list Interreg calls — applicants must monitor each programme they are eligible for individually.
