You only need a doctor’s sick note (fit note) if you are off work for more than 7 calendar days.
If you are off work for 7 days or less, you do not need to see a GP. You can complete an SC2 self-certification form instead.
You can complete this form online using the link above.
Fit notes can usually be issued from the date of your consultation. In some circumstances they may be backdated if this is clinically appropriate.
If your employer asks for a doctor’s note for less than 7 days of illness, this is not covered by the NHS. The practice may charge for providing a private sick note.
For more information about fit notes, please see the GOV.UK guidance for patients and employees.
