Sick Cert for One Day in Ireland: Do You Need a Doctor’s Note?

Last updated: March 2026

Many employees in Ireland wonder whether they need a sick certificate (sometimes called a sick note or doctor’s note) for just one day off work. In most cases, a one-day illness can be handled through self-certified sick leave, meaning a doctor’s note is not always required. However, some employers may require a medical certificate from day one, and certification is usually necessary if you want to claim statutory sick pay.

Understanding when a sick cert is required helps employees avoid workplace issues and ensures employers follow Irish employment law.

This guide explains:

• Whether you need a sick cert for one day in Ireland
• The difference between self-certified and certified sick leave
• When employers can legally request a doctor’s certificate
• How statutory sick pay affects certification requirements
• What happens after statutory sick pay is exhausted
• Your legal protections under the Sick Leave Act 2022

Quick Answer: Do You Need a Sick Cert for One Day in Ireland?

In Ireland, a sick certificate is not always required for a one-day illness absence.

In many workplaces:

• Employees can take 1–2 days of self-certified sick leave
  
• A doctor’s certificate is usually required from day 3 onward
  
• Some employers may require a sick cert from the first day
  

If you want to receive statutory sick pay under the Sick Leave Act 2022, a medical certificate from a registered doctor is normally required even for a single day’s absence.

Because workplace rules differ, the final requirement usually depends on your employer’s sick leave policy or employment contract.

What Is a Sick Cert in Ireland?

A sick certificate (doctor’s note or medical certificate) is a document issued by a registered medical practitioner confirming that an employee is medically unfit to work due to illness.

It typically includes:

• The patient’s name
• Confirmation that the person is unfit for work
  
• The start date of illness
  
• The expected return-to-work date
  

Medical certification is commonly required for:

• Longer illness absences
• Statutory sick pay claims
  
• Situations where an employer requires medical proof of illness.

Self-Certified Sick Leave in Ireland

Self-certified sick leave allows employees to take short illness absences without a doctor’s note.

Instead of providing a medical certificate, the employee confirms the illness themselves.

This is typically done by:

• Notifying their employer of the illness
• Completing a self-certification form when returning to work.

According to official sick leave guidance by HSE, you may be allowed up to 7 days of self-certified paid sick leave within a rolling 24-month period (adjusted proportionally if you work part-time).

This means that for illness absences of up to two consecutive days, a medical certificate is usually not required, unless your employer specifically asks you to provide one.

This policy mainly applies in the public sector, while private employers may set different self-certification rules.

Typical Workplace Policies

Many organisations allow:

• 1–2 consecutive days without certification
• A limited number of short-term illness absences per year

For example, some public sector policies allow:

• Up to 7 days of self-certified sick leave within a rolling 24-month period
• Absences of more than two consecutive days to be medically certified

These rules can vary between workplaces, so employees should always check their staff handbook or HR policies.

When Employers Can Require a Sick Cert for One Day

Although many employers allow short absences without certification, Irish employment law allows employers to request a medical certificate if it is part of company policy.

Situations where a sick cert may be required for a single day include:

• Your employment contract requires certification from day one
  
• There is a pattern of repeated short absences
  
• The absence occurs before or after weekends or holidays
  
• You want to claim statutory sick pay
• You are on a formal absence management programme
  

Employers typically outline these rules in:

• Employment contracts
• HR policies
• Employee handbooks

If your employer’s sick leave policy requires a cert from day one, they are legally entitled to enforce this. Refusing to provide a cert in such cases may result in the absence being treated as unauthorised leave.

Sick Cert Requirement for Statutory Sick Pay

The Sick Leave Act 2022 introduced statutory sick pay in Ireland to guarantee a minimum level of paid sick leave for employees.

To qualify for statutory sick pay, employees must:

• Have 13 weeks of continuous service
  
• Be certified by a registered medical practitioner as unfit for work
• Submit a valid medical certificate that covers each day claimed
  

Because certification is required, employees claiming statutory sick pay usually need a doctor’s certificate even for short absences.

Current Statutory Sick Pay Rules

• Employees are entitled to 5 days of paid sick leave per calendar year (subject to medical certification and minimum service requirements i.e. you’ve worked for your employer for 13 continuous weeks before you’re sick).
• This is paid by your employer at 70% of your regular daily earnings
• This is capped at €110 per day

This statutory entitlement is just a minimum. Many employers offer more generous sick pay schemes through their contracts.

The statutory entitlement is planned to increase gradually in future years, potentially reaching up to 10 days annually, subject to government implementation.

Because the scheme is expanding over time, employers may update their sick leave policies.

Examples of One-Day Sick Leave Situations in Ireland

Understanding real workplace scenarios helps clarify when certification is required.

Scenario 1: One day sick under a self-certified policy

An employee takes one day off with the flu.

Employer policy:

• Allows two days uncertified
  

Result:

• No sick cert required
  

Scenario 2: One day sick but claiming statutory sick pay

The employee wants to receive statutory sick pay.

Result:

• Medical certification required
  

Scenario 3: Employer requires certification from day one

The employment contract states that all illness absences require a doctor’s note.

Result:

• Employee must provide a sick cert even for one day
  

Scenario 4: Frequent short absences

An employee repeatedly takes single-day sick leave.

Employer may:

• require medical certification
• request return-to-work confirmation
  
• monitor absence patterns.

Scenario 5: Absence before or after a bank holiday

An employee calls in sick on the Friday before a bank holiday weekend.

Result:

• Many employers have specific policies requiring certification in this situation, even where self-certification normally applies. Always check your employer’s policy.

Can You Get a Sick Cert Online in Ireland?

Yes. Many GP services now offer online sick certs / medical certificates through telemedicine consultations. This is a convenient option for short illnesses that do not require an in-person examination.

Typical process:

1. Book an online appointment with a GP
2. Discuss symptoms during a consultation
3. Receive a digital sick certificate by email
   

Here’s our detailed guide on how to get an online sick note in Ireland.

Online consultations are commonly used for short illnesses such as:

• Colds and flu
• Migraines
• Stomach bugs
• Minor infections.

However, doctors must still assess whether the patient is medically unfit for work before issuing a certificate.

What Happens if You Don’t Provide a Sick Cert?

If your employer requires a sick certificate and you do not provide one, the absence may be treated as unauthorised leave.

Possible consequences may include:

• Loss of sick pay entitlement
• Absence recorded as unapproved leave
  
• Disciplinary procedures under company policy.

For this reason, employees should always follow their employer’s absence reporting procedures.

Employer Sick Leave Policies in Ireland

Irish employers are allowed to create their own sick leave policies, provided they meet the minimum standards set by the Sick Leave Act 2022. An employer scheme that is, on the whole, more favourable than the statutory minimum satisfies the employer’s obligations under the Act. The contractual scheme is a substitution for, not an addition to, the statutory entitlement.

These policies often include:

• Procedures for reporting illness
• When certification is required
• Limits on self-certified sick leave
• Return-to-work requirements.
• Absence management triggers

Key Takeaways

A sick cert for one day in Ireland is possible, but whether you need one depends mainly on your employer’s policies and whether you are claiming statutory sick pay.

Key points to remember:

• Irish law does not automatically require a sick cert for a one-day absence
  
• Many employers allow 1–2 days of self-certified sick leave
  
• Medical certification is usually required from day 3 onward
  
• A doctor’s certificate is normally required to claim statutory sick pay
  
• Some employers can legally require a sick cert from day one
  

Because workplace policies differ, employees should always review their employment contract or staff handbook to understand the exact rules.
