You only need a doctor’s note if you are unable to work and are ill for longer than seven calendar days. Your employer will provide you with an SC2 self-certificate form for shorter periods of illness.
An SC2 form can be downloaded from the this link: https://www.hmrc.gov.uk/forms/sc2.pdf
If you have consulted with a GP at the practice and discussed an ongoing sickness absence, a request for a certificate can be sent to the patient services team to process.
Fit Note/ Med3 Request/ Sick Note
This form should only be used to request a certificate where a patient has consulted with the practice regarding their condition or for a continuing absence, which the GP is aware of.
