Under COST rules in Horizon Europe, researchers and innovators affiliated to institutions based in Switzerland or the United Kingdom are fully eligible to participate in COST Actions. This includes:

• reimbursed participation in Action networking activities (meetings, conferences, Training Schools, Short-Term Scientific Missions (STSMs), and virtual mobility grants);
• possibility to be a main or secondary proposer in the COST Open Call for new Actions;
• eligibility to all leadership positions in ongoing Actions;
