ERC Consolidator Grant 2027 is open and Ruthless Evaluator is updated

ERC Consolidator Grant 2027 opened on 24 September 2026, and Ruthless Evaluator has already been updated for the new call.

The deadline is 12 January 2027. The official Work Programme gives the call an indicative budget of EUR 618 million and an estimated 296 grants. More importantly for applicants, the 2027 call introduces a substantially wider eligibility window and applies the current ERC proposal and evaluation structure in full.

For researchers who are deciding whether to apply, the key question is not simply whether the project is scientifically strong. It is whether the proposal makes a convincing ERC case: an important scientific question, ambitious objectives, a clear advance beyond the frontier of knowledge, a scientifically convincing approach, and a Principal Investigator with the creativity, expertise and capacity to execute the work.

That combination is demanding. It is also exactly why this call deserves more than a generic grant-writing checklist.

The official ERC Consolidator Grant page now lists the 2027 call with the 24 September 2026 opening date and the 12 January 2027 deadline. The controlling legal source remains the ERC Work Programme 2027.

The main ERC Consolidator Grant 2027 facts

The ERC Consolidator Grant supports excellent Principal Investigators who are consolidating their own independent research team or programme. The scheme is bottom-up, so there are no predetermined thematic priorities. Applications can come from any field of research, provided the planned work fits ERC frontier research ambitions.

The main call figures are:

• Opening date: 24 September 2026
• Deadline: 12 January 2027
• Indicative call budget: EUR 618 million
• Estimated number of grants: 296
• Maximum grant: EUR 2 million
• Maximum standard duration: 5 years
• Standard additional funding: up to EUR 1 million when duly justified
• Relocation additional funding: up to EUR 2 million for an eligible PI based outside the EU or an Associated Country and relocating to take up the ERC grant
• Minimum PI working time on the ERC project: 40%
• Minimum PI working time in an EU Member State or Associated Country: 50%

The funding model remains actual cost. Eligible direct costs can be reimbursed at 100%, with the applicable 25% flat rate for indirect costs under Horizon Europe rules.

These numbers matter, but they do not define what makes a proposal competitive. ERC evaluation is built around scientific excellence, not around market impact, commercialisation, TRL progression or the collaborative impact logic used in many Horizon Europe calls.

The eligibility window is much wider in 2027

One of the most important changes is the new Consolidator Grant eligibility period.

For the 2027 call, the first PhD must normally have been successfully defended more than 5 years and up to 15 years before 1 January 2027. The ordinary cut-off dates are therefore:

1 January 2012 to 31 December 2021, inclusive.

This is a major expansion compared with the previous model. It creates a broader applicant population and gives more researchers the opportunity to choose Consolidator Grant at a later stage of scientific independence.

The eligibility period can still be extended in properly documented circumstances. The official applicant guidance lists situations including maternity and paternity leave, parental leave, clinical training, long-term illness, disability, national service, major disaster, seeking asylum, gender-based violence and other forms of violence.

Applicants should verify the exact eligibility calculation and documentary requirements against the Information for Applicants to the Starting and Consolidator Grant 2027 Calls. Eligibility is an administrative condition, not a scientific evaluation score.

Another important rule is that a researcher may be Principal Investigator of only one ERC Consolidator Grant during their career. The 2027 Work Programme also contains application and resubmission restrictions that should be checked before significant proposal preparation begins. We previously covered the policy debate around these rules in our article on the ERC 2027 resubmission rules.

What kind of project does ERC Consolidator expect?

The ERC does not publish a thematic list of preferred project types. The scientific logic is instead defined by the nature of frontier research and by the evaluation elements.

A strong Consolidator proposal should address an important scientific question and define objectives that are ambitious enough to advance the frontier of knowledge. The planned approach must be scientifically convincing. At the second evaluation step, the methodology, working arrangements, timescales and resources must also show that the project can credibly achieve its goals.

This creates a useful distinction.

A proposal can be technically sophisticated and still be weak for ERC if the scientific question is not important enough. It can be methodologically rigorous and still be weak if the objectives do not move the field forward. It can be highly ambitious and still be weak if the approach is not convincing.

ERC also funds high-risk frontier research, but high risk is not a separate scoring line in the current Consolidator evaluation form. Risk should be understood in the context of ambition, scientific uncertainty, methodology and project credibility. A proposal does not become stronger by adding dramatic language about risk. It becomes stronger when the scientific uncertainty is justified by the potential advance and the research strategy is credible enough to investigate it.

The same discipline applies to impact. Applicants should not import the Horizon Europe collaborative-project logic of expected outcomes, exploitation pathways, market uptake and policy impact into the core scientific case unless those elements are genuinely relevant to the research. ERC scientific excellence is the centre of the evaluation.

The proposal structure makes Part I especially important

The 2027 application keeps the current two-part scientific proposal structure.

Part B1 contains Part I of the Scientific Proposal plus the Curriculum Vitae and Track Record. Part I has a maximum of 5 pages, excluding the cover page and references. The CV and Track Record use a combined maximum of 4 pages.

Part I should do three essential things: explain the current state of knowledge, define the scientific question and objectives, and present the overall scientific approach or research strategy. It should make clear what could be changed, opened or challenged if the project succeeds, and why the planned approach is scientifically convincing.

Part B2 contains Part II of the Scientific Proposal, with a maximum of 7 pages. This is the detailed implementation section, including research methodology, work plan, risk assessment, mitigating measures and any necessary background not already covered in Part I. The Funding ID section sits outside the 7-page limit.

Part A also matters scientifically at Step 2 because the Resources and Time Commitment information becomes available to reviewers. The Resources description has a maximum of 8000 characters, and the budget needs to be properly justified.

The practical implication is simple: Part I cannot be treated as an executive summary of Part II.

At Step 1, reviewers see Part I together with the CV and Track Record. They do not see Part II, Resources or Time Commitment. Part I must therefore stand on its own as the scientific case that earns further evaluation.

Step 1 and Step 2 assess different levels of evidence

The ERC Consolidator evaluation follows a two-step process after a single full submission.

At Step 1, Part I of the Scientific Proposal and the PI CV and Track Record are evaluated. Up to 44 proposals per panel can be retained for Step 2. The panel is testing whether the proposal presents an important scientific question, ambitious objectives, a genuine advance at the frontier of knowledge and a scientifically convincing approach. The panel also assesses PI ability to conduct ground-breaking research, creative and original thinking, and the scientific expertise and capacity required to execute the project.

At Step 2, the complete research proposal is evaluated. Reviewers can assess Part I, Part II, the CV and Track Record, Resources and Time Commitment. The scientific project evaluation now includes the appropriateness of methodology and working arrangements, as well as whether timescales and resources are adequate and properly justified.

Step 2 also includes a PI interview, normally around 30 minutes, combining a project presentation and questions from the panel.

The official wording is set out in Annex 1 of the Guide for Peer Reviewers for Starting and Consolidator Grant Calls, Version 7.0. That evaluation form is the right source for understanding what reviewers are actually asked to assess.

What the PI case needs to demonstrate

The Consolidator profile is not simply a senior version of Starting Grant.

The official Work Programme says that a Consolidator PI should already have shown evidence of research independence. That context matters, but the current evaluation form does not create a separate scored criterion called independence.

Reviewers assess three PI elements at both steps:

• ability to conduct ground-breaking research;
• evidence of creative and original thinking;
• scientific expertise and capacity to successfully execute the project.

A strong CV and Track Record should therefore help the reviewer answer those questions. A list of publications is not enough by itself. The official applicant guidance allows applicants to explain the significance of selected outputs, the role played in producing them, and how they demonstrate capacity to carry out the planned project.

That is valuable space. The goal is not to maximise the number of achievements. The goal is to make the scientific significance, contribution and trajectory legible to the panel.

This is particularly important for Consolidator applicants because the project and the PI case should reinforce each other. The proposal should feel like a credible next major scientific programme for a researcher who has established independence and is now consolidating a distinctive direction.

Common mistakes to avoid before January

A few recurring weaknesses are especially dangerous under the current ERC structure.

First, do not hide the central scientific question inside technical detail. Reviewers need to understand what the project is trying to change in the field and why the question matters.

Second, do not treat Part I as a compressed Part II. Step 1 reviewers need a complete scientific argument, not a teaser for information that appears later.

Third, do not confuse ambition with scale. A large team, expensive equipment or many work packages do not make a project ERC-level. The scientific advance must justify the scale.

Fourth, do not rely on reputation as evidence. Host prestige, journal names and publication counts do not substitute for a clear explanation of scientific contribution, originality and execution capacity.

Fifth, do not let B1 and B2 tell different stories. Objectives, approach, methodology, scope, resources and timing should form one coherent project. Differences in level of detail are normal. Contradictions are not.

Finally, do not import irrelevant commercial evaluation logic. ERC Consolidator is not EIC Accelerator. Market size, customers, revenue projections, TRL progression and go-to-market planning are not ERC Consolidator scientific evaluation elements unless the research itself makes some of them directly relevant.

Ruthless Evaluator is already updated for ERC Consolidator 2027

When we first added ERC support, we explained why Ruthless Evaluator needs programme-specific logic for ERC proposals. The new Consolidator call is a good example of why that matters.

We have now updated Ruthless Evaluator to the current ERC Consolidator Grant 2027 source set, including:

• the ERC Work Programme 2027;
• the Consolidator Grant 2027 official application form and proposal structure;
• Information for Applicants for Starting and Consolidator Grant 2027;
• the current Guide for Peer Reviewers and Annex 1 evaluation form;
• the new 5 to 15 year eligibility window and 2027 call conditions;
• the current Step 1 and Step 2 evaluation logic;
• the current proposal page limits and resource requirements.

The previous Consolidator edition has been retired from the active Ruthless Evaluator configuration. The evaluator now resolves ERC Consolidator to the 2027 call and applies the updated source materials and evaluation logic.

The purpose is not to imitate an ERC panel decision or to predict funding. It is to stress-test the draft against the official evaluation elements and the evidence available in the uploaded application. Ruthless also applies internal diagnostic lenses for issues such as initial evaluator conviction, implementation credibility and consistency between proposal parts, while keeping those lenses clearly separate from official ERC criteria.

If you are preparing a Consolidator application, you can use the ERC proposal evaluator to review the draft before submission.

The deadline is January, but the Step 1 case should be built now

12 January 2027 may look comfortably distant in late September. For an ERC Consolidator application, it is not.

The hardest work is rarely the final formatting. It is making the scientific argument strong enough that Part I can carry the project through Step 1 while remaining fully consistent with the deeper methodology, resources and execution plan in Part II.

That takes iteration. It also takes critical review from people who are not already immersed in the project.

The current call gives applicants a wider eligibility window and a clear evaluation framework. It does not reduce the standard. Scientific excellence remains the sole ERC criterion, and the proposal still has to make ambition, originality, credibility and PI capacity visible under severe space constraints.

For applicants, the most useful question is therefore not whether the draft contains all the right sections.

It is whether a demanding reviewer can see, quickly and convincingly, why this scientific question matters, what will change if the project succeeds, why the approach can work, and why this PI can deliver it.

That is the case the proposal needs to make before 12 January.
