What changed in the 2026 templates, and where your text now belongs

Part B version 2.0 is not a tidy-up of the previous template. It cut the narrative to 20 pages, rebuilt the question structure, and moved the entire work-package apparatus into a separate annex. A proposal written to last year's shape is not wrong — it is misfiled, and that is one of the easiest things for an evaluator to notice.

The three changes that move your text

The change log inside Part B v2.0 describes itself in one line: “First version of the simplified template implementing the 2026 EIC Work Programme.” Three consequences follow from that, and each one relocates material you have probably already written.

1. The narrative is 20 pages, and the cover counts

The full proposal used to run to roughly fifty pages. It is now 20 pages including the cover page, with an executive summary of about half a page. The enforcement is unusually blunt: if you upload an over-long proposal before the deadline you get a warning and a chance to fix it, but after the deadline the excess pages are automatically made invisible and the experts simply never see them. Nobody tells you which pages were lost. You are also told explicitly that the proposal is self-contained and that experts are instructed to ignore hyperlinks designed to expand it — so the old trick of parking detail behind a link does not work.

The formatting conditions are worth reading carefully because one clause catches almost everyone: the 11-point minimum and single line spacing apply to text inside tables, not only to body paragraphs. Shrinking a work-package table to reclaim half a page is a visible breach.

2. Three topic areas, mapping one-to-one onto the criteria

The structure is now flat and predictable. Topic area 1 is Technology and carries Excellence. Topic area 2 is Market and carries Impact. Topic area 3 is Team, financial needs and implementation, and carries Level of risk, implementation and need for Union support. Underneath sit ten numbered questions, two of which are conditional.

SectionWhat it now asks
1.1Novelty and breakthrough nature — the deep-tech basis, disruptive potential against existing and alternative solutions, a significant cost or performance improvement, and empirical data.
1.2Technology maturity — demonstration that all aspects of TRL 5 are complete, meaning validation in a relevant environment for your application.
1.3IP strategy — patents granted or pending, trade secrets, other IP elements, and FTO status.
2.1Market opportunity — total market and realistic share, go-to-market, customer value proposition, partnerships and adoption.
2.2Business and revenue model and growth strategy — the model, the projections, and the assumptions behind them.
2.3Broader impact — European technological leadership, reduced dependency on other regions, environmental and social impact.
2.4Challenge alignment — Challenges only, with metrics.
2.5STEP impact — only for Challenges within STEP scope, with metrics.
3.1Team capability — plus two official tables: the team table (with a gender column and a commitment percentage) and the governance table, whose fully diluted column must total exactly 100%.
3.2Risk level of the investment and leverage effect — branches by funding form.
3.3Risk management — technological, market, financial and regulatory risks, mitigation, standards and future regulation.

A useful discipline: answer 2.4 and 2.5 only when your topic triggers them. An Open proposal that answers Challenge alignment anyway has spent page budget on a question nobody asked.

3. Implementation moved out of Part B into its own annex

This is the change that relocates the most text. Work packages, deliverables, milestones, timing and effort no longer live in the narrative. They live in a separate implementation plan annex of up to 10 pages, structured around table 3.1a for the grant component (activities up to TRL 8), table 3.1aa for the investment component (TRL 9 and below where necessary), table 3.1b for the work-package descriptions, and table 3.1c for the grant deliverables.

Two knock-on effects are easy to miss. First, if you leave that material in Part B you lose pages that Technology, Market and need for Union support badly need — and you still have to file the annex. Second, the lump-sum budget workbook still instructs you to match “the list of work packages in the main proposal (Table 3.1a)”. That table is now in the annex. Follow the reference; the table is not missing.

The quieter changes

The ownership control declaration is triggered by a different thing

In 2024 the ownership control declaration was introduced as a mandatory annex for AI and quantum applications. That is no longer the rule. Version 5.0, dated 1 January 2026, is required for proposals under Challenge 2.4, Boosting the European Critical Raw Materials value chain, and for Open proposals within the scope of that Challenge — and in both cases only when the request is grant only. Blended finance and equity-only proposals under Challenge 2.4 do not file it.

Where it does apply, the disclosure threshold is 5%: any owner holding, directly or indirectly, at least 5% of capital or at least 5% of voting rights, followed by corporate governance, commercial links, financial links and any other source of control. Supporting documents are not required at application — they are requested later through a task notification to your PIC account.

Equity-only proposals upload templates blank

If you are requesting equity only, you still upload the lump-sum budget workbook and the implementation plan — as blank documents. Omitting them is a defect; uploading them blank is compliance. It follows that the #DIV/0! values sitting in an untouched financial workbook are template artefacts and mean nothing.

Letters of intent come with explicit failure criteria

The guidance template asks for all letters merged into a single PDF and lists the elements a good letter contains. More usefully, it names what fails: generic copy-paste “support” letters that outline no specific commitment, unsigned letters, undated letters, and letters from companies that are not customers, users or real investors. That is unusually direct language for an official template, and it is worth taking literally.

The AI-use clause is a disclosure obligation, not a prohibition

The template's guidance on generative AI requires applicants to verify accuracy and citations, provide a list of sources including AI-generated ones, check for reproduced text, and acknowledge the tool's limitations — while being transparent about which tools were used and how. Applicants remain fully responsible for every part of the proposal, including the parts a tool produced.

The Work Programme sits above all of these. Where the amended EIC Work Programme 2026 and a template disagree, the Work Programme controls.
