What should you know about a medical certificate for leave of absence?

The clinician decides whether a certificate is medically appropriate after discussing your symptoms, examining you when needed, and considering the demands of your job. The document may state that you are unfit for work or may describe restrictions and a review date. It is evidence of a health-related need for leave, not a guarantee that an employer will accept every administrative detail. Workplace policies and local requirements can affect what information must be submitted, so share only the document requested through the proper channel.

Book a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) and explain when symptoms began, what work involves, and which tasks you cannot safely perform. Bring relevant medical records and medicine details. Ask how the certificate will be issued, the period it covers, whether a review is needed, and how to correct an error. A [Sick Leave Certificate](/treatments/consultations-and-assessment/sick-leave-certificate/) page provides related guidance. If exhaustion, detachment, or reduced functioning is linked to [Burnout](/conditions/burnout/), mention this clearly so the underlying problem can also be addressed.

Seek urgent help for chest pain, severe breathing difficulty, fainting, new confusion, thoughts of harming yourself, or another immediate safety concern. Arrange medical review when symptoms persist, worsen, prevent ordinary activities, or make work unsafe. Do not use a certificate request to postpone care for a serious illness; documentation and treatment can be handled together.

Ask what information you should bring, whether work restrictions are safer than full leave, when you need reassessment, and how to obtain a corrected or updated document.
