The Action

All the necessary information on what the COST office does and what a COST action is can be found on the COST website, please check the FAQ on the Cost website for more information.

Yes you can! Everyone from all over the world can join the action. However if you’re from outside of Europe it is very likely that you are not eligible for reimbursement of your expenses. But as we aim to keep the website up-to-date and have an active forum community you can even contribute from afar! Please don’t hesitate to sign up and sign up for any future events. More information on eligibility for reimbursement can be found in the COST vademecum, pages 25-29.



Eligibility for a certain type of event depends on several factors. Firstly you have to be working in a COST country and your country has to have signed the MoU. You can check here if your country did. Furthermore the number of participants for each event is limited, because the amount of funds is limited. Therefore the Chair/Core Group/Group leaders will decide on who will be eligible for reimbursement. For MC meetings all MC members are automatically eligible for reimbursement.

Upcoming events will be shown in the ‘Events->upcoming’ webpage. Here you can register for the events. Remember that this registration is only to show your interest in joining the event to the organisers of the event. You will be notified by the organisers by means of official COST invitation when you are officially invited to the event.

Please do not book any of your travel tickets before receiving the official COST invitation! If you have not received an official invitation you will not be eligible for reimbursement.


Reimbursement and E-Cost 

The Cost action will reimburse all travel costs and will reimburse meals and lodging based on a flat rate which will be established before the event. For an overview of what can be reimbursed and what rules apply please check the COST vademecum.

You will need to keep receipts/tickets of your transport. As the reimbursement for meals and lodging is a flat-rate you will not need to keep these receipts.

A manual to Travel reimbursement can be downloaded from here. Please read the instructions thoroughly and if you have any questions remaining after that please send your question to Please make sure you submit your claim within 30 days after the meeting.

After the claims are processed the money will be reimbursed to your account. The amount of time needed for processing the claim may vary, but count on at least 2 weeks.
