A Global Challenges theme

The European Commission has published all of the 2026-27 Horizon Europe Work Programmes, which list the funding opportunities under the 2026-27 call topics.

No matter your field – whether you’re a business, university, research institute, charity, or not-for-profit – you could be eligible to apply for Horizon Europe funding to advance your cutting-edge research and innovation, fostering lasting impact and meaningful change.

Our Innovate UK European Team and UK National Contact Points can support you with these exciting potential funding opportunities and help you get the most out of Horizon Europe.

Applying from the UK

UK organisations and businesses can apply for Horizon Europe funding, working as part of a consortium with at least three countries, one of which must be an EU Member State (see “Who can apply?” below). If you are interested in one of the calls and would like to find a collaboration partner, contact Innovate UK Business Connect’s European Programmes team.

If you have formed a consortium and are ready to apply, you can do so via the Horizon Europe Funding and Tenders Portal. Click here to see all open Horizon Europe calls (you will need to search for the title of the call you are interested in).

Some calls in Cluster 5 are already open, but some will not be open until 2027.

The Climate, Energy and Mobility Work Programme

Funded by the EU’s Horizon Europe programme for Cluster 5, this Work Programme document outlines the expected impacts as set out by Pillar 2 of the strategic plan and details specific calls for proposals and their relevant conditions to apply.

The available topics in Cluster 5, “Climate, Energy and Mobility”, are summarised below. For 2026-27, they have been subdivided into 6 Destinations:

  • Climate sciences and responses for the transformation towards climate neutrality
  • Cross-sectoral solutions for the climate transition
  • Sustainable, secure and competitive energy supply
  • Efficient, sustainable and inclusive energy use
  • Clean and competitive solutions for all transport modes
  • Safe, Resilient Transport and Smart Mobility services for passengers and goods

For further details on each call, view the 2026-27 Cluster 5 Work Programme.

The calls in this cluster have opening dates varying from Dec 2025 to Aug 2027, with closing dates from Mar 2026 to Dec 2027: please check the details for each individual call before starting the application process.

  • Unless otherwise provided for in the specific call/topic conditions, only legal entities forming a consortium are eligible to participate in Horizon Europe actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:

    • at least one independent legal entity established in a Member State;
    • and at least two other independent legal entities, each established in different Member States or Associated Countries (this includes the UK).

    Our European team can help you find eligible partners to form a consortium.

    There may be further eligibility conditions for specific topics. Please check the Work Programme and contact our team to ensure your eligibility before applying.

  • The Info Day for Cluster 5 is on Thursday 15 January 2026, at 9am CET (8am UK time). A recording will be available afterwards.

    Potential applicants may also wish t0 attend the Cluster 6 Info Days (Food, Bioeconomy, Natural Resources, Agriculture and Environment) as these have significant topical overlap, especially with Climate: these will be on 22-23 January from 9am CET (8am UK time).

    Registration for the Cluster 5 brokerage event on 14 January is now closed; contact Innovate UK Business Connect’s European team if you would like help in finding a consortium partner.
