You only need a doctor’s sick note if you are unable to work and are ill for longer than seven calendar days. Your employer will provide you with an SC2 self-certificate form for shorter periods of illness.
New sick note
Your doctor will usually need to see you to provide a sick note for a new period of illness. If you have had an operation, and the hospital has not provided you with one, then your doctor might be able to issue this after a telephone consultation.
Ongoing periods of ill health
If you need to renew your sick note, you might be asked to make a doctors appointment for a review.
If your sick note has run out, the doctor is able to backdate it if this is appropriate.
