What about any medical or physical conditions that may require to provide the applicant with special arrangements?

If you or any dependents who are applying with you have a medical or physical condition which may require special arrangements to be made in order for your biometric features to be recorded, you must obtain a letter or other document giving the details of any such condition and enclose it with your application.

Appropriate documentary evidence would be a letter from a treating clinician, such as a practicing doctor registered with the General Medical Council, giving details of the condition and/or special needs and explaining any arrangements that may be necessary.
