You do not require a doctor’s sickness certificate for any illness lasting seven days or less. Your employer may however require you to complete a self-certification form, an SC2, which 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 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 from your doctor is strong evidence that you are sick, and would normally be accepted, unless there is evidence to prove otherwise.
If you require an additional sick note for the same medical condition, your doctor may need to issue an additional sick note. You can request an additional sick note by filling out our Additional Sick/Fit Note Request.
You could also provide evidence from someone who is not a medical practitioner, such as a dentist. Your employer will decide whether or not 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
The ‘fit note’ was introduced on 6 April 2010. With your employer’s support, the note will help you return to work sooner by providing more information about the effects of your illness or injury.
