Mental Health Fit Note UK (2026 Guide) | SSP & Employee Rights

Last updated: May 2026

Mental health conditions such as anxiety, stress, depression, and burnout are now widely recognised in the UK as legitimate reasons for taking time off work. If your mental health is affecting your ability to work safely or carry out your duties properly, you may be able to get a fit note (sick note) from a GP or another authorised healthcare professional.

Many employees still feel uncomfortable taking time off for mental health due to stigma or fear of workplace judgement. However, under UK employment law, mental health conditions are treated the same as physical illnesses when it comes to sick leave and workplace protections.

This guide explains:

• How mental health fit notes work in the UK
• When you may need a fit note
• Your employment rights
• Statutory Sick Pay (SSP) rules
• Employer obligations

Can You Get a Fit Note for Mental Health in the UK?

Yes. In the UK, you can get a fit note for mental health conditions if your condition affects your ability to work safely or effectively.

Mental health conditions are generally treated in the same way as physical illnesses under UK sick leave and employment protections.

A GP or healthcare professional may issue a fit note for:

• Anxiety
• Stress
• Burnout
• Depression
• Panic attacks
• PTSD
• OCD
• Bipolar disorder
• Other mental health conditions affecting your ability to work

The key factor is whether your condition makes you medically unfit for work.

If your symptoms are affecting:

• Concentration
• Sleep
• Decision-making
• Emotional regulation
• Daily functioning
• Ability to cope at work

a healthcare professional may recommend time off work or workplace adjustments.

Taking sick leave for mental health is valid, medically recognised, and legally protected in the UK.

What Is a Fit Note in the UK?

A fit note (sometimes called a sick note or Statement of Fitness for Work) is an official medical document confirming that:

• You are not fit for work, or
• You may be fit for work with adjustments

Fit notes can be issued by:

• GPs
• Hospital doctors
• Nurses
• Pharmacists
• Physiotherapists
• Occupational therapists

According to NHS fit note guidance, fit notes are usually required if you are off work for more than 7 consecutive days, including weekends and non-working days.

When Do You Need a Fit Note in the UK?

1. Short Absences (7 Days or Less)

You usually do not need a fit note.

Instead, you can self-certify your illness. Your employer may ask you to:

• Complete a self-certification form
• Fill in form SC2
• Confirm your illness in writing

2. Longer Absences (More Than 7 Days)

If your illness lasts longer than 7 consecutive days, your employer can ask for a fit note.

This is commonly needed for:

• Statutory Sick Pay (SSP)
• Company sick pay schemes
• Longer-term sickness absence

3. From Day One (Some Employers)

Some employers may request medical evidence earlier depending on workplace policy, especially:

• During probation periods
• For repeated absences
• For occupational sick pay claims

Employers usually cannot require an NHS fit note for the first 7 calendar days of absence, although they may request other forms of evidence in line with workplace policy.

How to Get a Mental Health Fit Note (Step-by-Step)

Step 1: Book a GP Appointment

You can:

• Visit a GP surgery
• Use an NHS online consultation service
• Depending on the service you use, another authorised healthcare professional may also be able to issue a fit note.

You can visit a GP in person or online, depending on your situation.

If symptoms are severe or urgent, seek medical help as soon as possible.

Step 2: Explain Your Symptoms Honestly

Try to explain how your mental health is affecting your daily life and work.

This may include:

• Anxiety or panic symptoms
• Difficulty concentrating
• Sleep problems
• Emotional exhaustion
• Burnout
• Work-related stress
• Low mood or depression

Healthcare professionals assess how your condition affects your ability to function and work safely.

Step 3: Assessment and Recommendations

Your healthcare professional may:

• Discuss your symptoms
• Ask about work pressures
• Assess your mental wellbeing
• Recommend treatment or support
• Suggest time off work

In some cases, they may recommend workplace adjustments instead of complete absence.

Step 4: Receive Your Fit Note

If you are considered unfit for work, you may receive:

• A digital fit note
• A printed fit note
• Recommendations for workplace adjustments

The fit note usually covers a specific period and may require review if your absence continues.

Does a Fit Note Mention Mental Health?

Usually, not in detail.

A fit note often simply states:

• “Not fit for work”
• Or “May be fit for work”

Your employer does not automatically have a right to know your exact diagnosis.

Medical information is protected under UK data protection law, including the UK GDPR and Data Protection Act 2018.

In some cases, you may choose to share more information if workplace adjustments are needed.

Statutory Sick Pay (SSP) for Mental Health Leave

Mental health-related absences qualify for Statutory Sick Pay in the same way as physical illnesses.

According to GOV.UK – Statutory Sick Pay Guidance:

• Eligible employees can receive at the current government rate (up to £123.25 per week in 2026)
• SSP can be paid for up to 28 weeks
• SSP is paid by your employer
• Tax and National Insurance are deducted

To qualify, you generally must:

• Be classed as an employee
• Be off sick for at least one qualifying day
• Follow your employer’s reporting procedure

What if Your Mental Health Condition Is Long-Term?

If your mental health condition has:

• A substantial effect on daily activities
• Lasted or is expected to last 12 months or more

it may qualify as a disability under the Equality Act 2010.

This may give you additional legal protections, including the right to reasonable adjustments such as:

• Flexible working
• Reduced hours
• Phased return to work
• Adjusted duties
• Remote working arrangements

Employers must avoid discrimination related to disability and mental health conditions.

Can You Be Dismissed While Off Sick for Mental Health?

Not simply for being unwell.

Employees may be protected against unfair dismissal in situations involving certified sickness absence, depending on their employment status and circumstances.

However:

• Long-term absence may still lead to formal review procedures
• Employers can assess whether you are capable of returning to work
• Employers must follow fair procedures

They should:

• Consider medical evidence
• Discuss adjustments
• Explore alternatives before dismissal

If you believe you have been treated unfairly, you may wish to seek advice from:

• ACAS
• Citizens Advice
• An employment solicitor

Can You Work While Signed Off Sick?

If you are signed off as not fit for work, you would generally not be expected to work during that period.

A fit note confirms that your condition affects your ability to work safely or effectively.

In some cases, a fit note may state that you:

• “May be fit for work” with adjustments
  rather than fully unfit.

Employers should not pressure employees to work while medically signed off.

Occupational Health Assessments

For longer absences, your employer may refer you to occupational health.

This is common and does not necessarily mean your employer doubts your condition.

Occupational health assessments may help:

• Assess fitness for work
• Recommend workplace adjustments
• Support phased return plans
• Reduce risk of relapse

The occupational health professional usually provides recommendations rather than detailed confidential medical information.

Returning to Work After Mental Health Leave

Returning gradually is often recommended after mental health-related absence.

Supportive return-to-work arrangements may include:

• Reduced hours initially
• Temporary workload adjustments
• Flexible scheduling
• Remote or hybrid working
• Regular wellbeing reviews

A phased return can help reduce stress and support long-term recovery.

Common Mistakes to Avoid

Many employees delay getting support because they:

• Feel guilty about taking time off
• Assume mental health leave is “not serious enough”
• Avoid speaking honestly to a GP
• Return to work too early
• Fail to keep employers updated

Seeking support early often leads to better recovery outcomes.

Key Takeaway

Taking time off for mental health is not a weakness. Mental health conditions are recognised medical issues, and UK employees have important legal protections when they need time away from work.

If your mental health is affecting your ability to cope at work, the most important step is speaking honestly with a healthcare professional as early as possible.

Support, treatment, and workplace protections are available — and you do not have to manage everything alone.
