How to Get a Sick Off / Medical Leave Certificate in Kenya

A medical leave certificate, commonly called a sick off in Kenya, is a document from a qualified doctor certifying that you're unfit to work due to illness. Your employer will likely demand one if you're absent for more than three days, and some organizations require it from day one. Without it, you risk losing pay or facing disciplinary action.

The process is straightforward but depends on where you seek treatment. Whether you visit a private clinic, a government hospital, or a registered doctor's office, the steps remain similar.

Where to Get Your Medical Leave Certificate

Private clinics and hospitals are the fastest option. They typically issue certificates on the same day you're seen, often within minutes. You'll pay a consultation fee—usually between KSh 1,000 and KSh 3,000—plus the certificate fee, which ranges from KSh 500 to KSh 1,500 depending on the facility.

Government hospitals like Kenyatta National Hospital or your county referral hospital are free or heavily subsidized, but the process moves slowly. You may wait hours to see a doctor, and getting the certificate might take an additional day or two.

Some workplaces have appointed medical officers or partner clinics. Check your employee handbook or ask HR if your company has a preferred healthcare provider. Using them sometimes speeds up the process and may even be free.

What You'll Need and What to Expect

Bring your national ID or passport. The doctor will examine you, ask about your symptoms, and decide whether you genuinely need time off work. Be honest—doctors can tell when you're exaggerating, and a certificate based on lies could land you in trouble with your employer or the Medical and Dentists Board, which regulates practitioners in Kenya.

The certificate itself is a simple document. It states your name, the diagnosis (or just "unwell" if the doctor prefers discretion), the date issued, and how many days you're certified unfit to work. Some certificates are handwritten; others are printed. Both are legally valid.

Most doctors will issue the certificate for however many days you genuinely need—typically one to five days for minor illnesses. If you're seriously ill, they may certify you for longer. Don't ask for more days than necessary; it weakens your credibility if you return to work looking perfectly fine.

If you need legal advice about your rights regarding sick leave or if your employer is refusing to accept a valid certificate, employment law experts can guide you through Kenya's labor regulations. The Employment Act sets minimum standards for leave that all employers must follow.

After You Get the Certificate

Submit it to your HR or line manager as soon as you return to work. Keep a copy for your personal records. Most employers file the original and won't return it, so don't expect to see it again.

If your employer rejects a genuine medical certificate or penalizes you for using sick leave legally, that's a breach of the Employment Act. You can escalate the matter to your county labor office or seek guidance from verified employment law experts on Kaziiko who understand workplace rights in Kenya.

Frequently Asked Questions

Can I get a medical leave certificate without visiting a doctor?

No. A valid certificate must be issued by a licensed medical practitioner—doctor, clinical officer, or dentist. Anything else is forged and could result in dismissal and criminal charges.

How long does a medical certificate last once issued?

It's only valid for the specific dates and number of days stated on it. Once those days pass, you need a fresh certificate if you're still unwell.

What if my employer doesn't accept my medical certificate?

First, confirm it's from a registered practitioner. If it is and your employer still refuses, report it to your county labor office or contact an employment law advisor. Rejecting legitimate medical certificates violates Kenyan labor law.

Do I need to disclose my diagnosis to my employer?

No. Your doctor can write "unwell" or "unfit for work" without listing the specific condition. Your medical information is private unless you choose to share it.
