If you have been ill for 7 days or less you don’t need to see a doctor. You can complete a Self Certification form yourself. However some employers insist on a doctor’s note regardless. A doctor’s note under these circumstances involves a charge of £22.
Many employers have their own self-certification forms. If your employer doesn’t have its own form you can download this Self Certification Form (PDF) . Please print it, fill it in and hand it in to your employer. You do not need to see a doctor.
