Seven calendar days or less
You do not normally need a fit note from a healthcare professional. Your employer can ask you to confirm your illness through self-certification.
Self-certification guidanceSick and fit notes
Choose the option that matches how long you have been unable to work.
More than seven calendar days
You may need a fit note if illness or injury has prevented you from working for more than seven calendar days, including weekends and bank holidays.
Request a fit noteReturning to work
You should return when you feel able. You do not usually need another appointment simply to confirm that you are fit to return before the end date of a fit note.
