Registration Cancellation Policy

  • No refunds to cancellations from 1 July 2026.
  • Cancellation requests received in the period 1-30 June 2026 will incur a 10% cancellation fee
  • Cancellation requests received before 1 June 2026 will be reimbursed in full but all associated banking costs will be born by the registrant
  • All accepted papers must be accompanied by 1 full (non-student) registration and fees will not be reimbursed if doing so would break this rule

How to register

Note: On the registration portal, be sure to fill-in all required options, including less obvious ones such as the entry for “Mentor/mentee programme please select” and to specify something for “Extra page charges” even if to select “No extra pages required”. If you find that it is not possible to select a non-zero number of tour/reception/banquet tickets, it is probably because a required field was not answered.

Visa Procedures

You can check whether you will require a visa to attend the conference on the UK Government website: https://www.gov.uk/check-uk-visa

ICS’26 will be an in-person event. We encourage prospective attendees who need a visa to request this as soon as possible. We will be able to provide letters of invitation to all registered attendees. We can also provide you with an “intent to participate” letter that states you have submitted a paper/poster to the conference and are awaiting the outcome of the review process before registering - this may allow you to start your visa application earlier. Note that the intent to participate is not the same as a letter of invitation, which you would still need to request in addition after completing the registration. Letters can be requested by email from ics26.chairs@gmail.com. Receipt of an invitation letter does not imply acceptance of submitted papers or the ability to present.

Required details include:

  • full name (as it appears on your passport)
  • passport number
  • date of birth
  • nationality
  • email address
  • paper/poster title and submission ID
  • registration details (if available)
