How do I write a self-certify sick note letter for work in the UK?

Self Certify Sick Notes

If you’re feeling unwell and need to notify your employer, a sick note letter can help document your absence. In the UK, you can write your own sick note for absences up to 7 consecutive days. However, for longer absences or official documentation, employers often require a signed medical sick note from a qualified doctor.

When Can You Write Your Own Sick Note?

For short absences due to illness (typically up to 7 consecutive days), employees in the UK are allowed to self-certify, meaning they can inform their employer of their illness without a formal medical document. Many employers have a standard template for this kind of notification, so it’s best to check with your HR department.

For absences beyond 7 days, UK employers generally require an official sick note, which is issued by a doctor. If you need a professional medical sick note, our doctors can help you with this process.

Steps for Writing a Sick Note Letter

  1. Begin with Your Information
    Start the letter with your name, position, and the date. This ensures that your employer knows who is writing and when the note was submitted.

  2. Address the Letter Properly
    Address it to your supervisor or the HR department, depending on your company’s protocol.

  3. State the Dates of Absence
    Clearly mention the start and end dates of your absence due to illness. This will help the employer understand the duration of your sick leave.

  4. Expected Return Date
    Mention when you plan to return to work. If your condition improves sooner or worsens, keep your employer informed as appropriate.

  5. Express Appreciation
    Close the letter on a polite note, thanking them for their understanding.

Why It’s Best to Have a Sick Note Signed by a Doctor

If your absence exceeds 7 days, or if your employer requires a doctor’s certification, it’s best to obtain a medical sick note. Not only does a doctor’s note serve as formal documentation, but it also provides your employer with verified information about your condition.
