How to Request a Fit Note
If you are off work for 7 days or less, you do not need to give your employer a sickness certificate or other proof of sickness from a medical professional.
Your employer may however require you to complete a self-certification form (SC2) which is available from your employer or you can download it from the HMRC website.
You must give your employer a doctor’s ‘fit note’ (sometimes called a ‘sick note’) if you’ve been ill for more than 7 days in a row and have taken sick leave. This includes non-working days, such as weekends and bank holidays.

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 and would normally 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 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 - '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 by providing more information about the effects of your illness or injury.
