You only need a doctor’s note if you are unable to work due to illness for longer than seven calendar days. If you are off less than 7 days your employer should provide you with a SC2 self-certificate form which covers you for the 1st 7 days. If they are unable to provide this form then a SC” self-certification form can be collect from the reception desk.
For patients needing a sick note due to a hospital admission, then this must be provided by the hospital itself, covering the period they expect you to be incapacitated for. The Doctor is unable to provide sick notes for hospital stays as they are not always aware of the expected recovery period, unlike their counterparts in hospital.
Doctors at the surgery do not usually do ‘return to work’ assessments, although if your employer requires this you are welcome to re-visit the surgery.
