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 (SC2) which is available from your employer or on the HMRC website.
Evidence That You Are Sick
PLEASE NOTE YOU ARE SELF CERTIFIED FOR 7 DAYS AND A SICK NOTE IS NOT REQUIRED FOR THIS PERIOD OF TIME. However if your employer does require a sick note the Surgery can provide one at a private charge of £15.00.
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).
Here at St Peters Surgery the GPs will require an appointment to assess your fitness before issuing you with a fitness to work certificate. Please make a non urgent appointment with you GP.
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.
