If you’ve been off sick for more than 7 days
For absences of over 7 days, you’ll need medical evidence for your employer. For this, you’ll need a doctor’s Fit Note.
To request a fit note:
- fill out a fit note request form
If you’ve been off sick for 7 days or less
For illnesses lasting 7 days or less, you don’t need a fit note but you may need to complete a self-certification form. You can obtain one on this website – www.gov.uk/government
