Sickness Certificates

Last Updated: Tuesday, 10 October 2023

Overview

You do not need a doctor's sickness certificate for any illness lasting seven days or less. Your employer may ask you to complete a self-certification form (SC2). This is available from your employer or on the HMRC website.

Evidence that you are sick

If you are sick for more than seven days, your employer can ask you to give them some form of medical evidence to support payment of SSP (statutory sick pay).

It is up to your employer to decide whether you are incapable of work. A medical certificate, now called a 'Statement of Fitness for Work’ (see below) from your doctor is strong evidence that you are sick. This would usually be accepted, unless there is evidence to prove otherwise.

You could also provide evidence from someone who is not a medical practitioner, e.g. a dentist. Your employer will decide if this evidence is acceptable. If your employer has any doubts, they may still ask for a medical certificate from your GP.

Statement of Fitness for Work - ’Fit Note'

The 'fit note' was introduced on 6 April 2010. With your employer's support, the note will help you return to work sooner. The sick note provides more information about the effects of your illness or injury.
