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
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.

Copying Letters To Patients
Copies of letters concerning you which are sent by your GP to another health professional are available on request.
NHS England require that the net earnings of doctors engaged in the practice is publicised, and the required disclosure is shown below. However it should be noted that the prescribed method for calculating earnings is potentially misleading because it takes no account of how much time doctors spend working in the practice, and should not be used to form any judgement about GP earnings, nor to make any comparison with any other practice.
The average pay for GPs working in ST GEORGE’S MEDICAL PRACTICE in the last financial year (2016/17) was £127, 784 before tax and National Insurance.
This is for 2 full time GPs, 1 part time GPs and 0 locum GPs who worked in the practice for more than 6 months.
