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 may involve a charge.
Many employers have their own self-certification forms. If your employer doesn’t have its own form you can complete this Self Certification Form. Please fill it in, print it and hand it in to your employer. You do not need to see a Doctor.
