A significant proportion of the doctor’s workload relates to requests for medical sickness certificates.
For illnesses that lasts up to 7 days complete a self certification which is available from your employer or can be downloaded from the HMRC website.
Illnesses lasting longer then 7 days you will require a sick note from the doctor. The doctor will need to either see you at the beginning of the illness, or see evidence from another doctor (hospital correspondence) before an initial sick note can be issued.
Follow-on sick notes can be requested by contacting the receptionist on the day it is due. (An appointment is not always necessary). Follow-on sick notes are not considered urgent and can be back dated.
