Stress is one of the most common reasons people struggle at work in the UK. Yet many employees hesitate to take time off because they worry stress won’t count as a “real illness” or that it could affect their job.
This guide explains whether you can legally take time off work due to stress in the UK, how stress-related sick leave works, how pay is handled, and what to do if your employer questions your illness.
Does Stress Count As a Valid Reason For Sick Leave in the UK?
Yes, when it is medically certified.
In the UK, “stress” itself is not a formal diagnosis, but doctors often certify employees unfit for work due to stress-related conditions, such as:
If you receive a valid fit note (also known as Statement of Fitness for Work), your employer must treat your absence as certified sick leave.
Do I Need a Fit Note for Stress Leave?
In the UK:
- You can self-certify for the first 7 calendar days of illness (including weekends).
- After 7 days, you usually need a fit note from a GP.
The fit note does not need to disclose private medical details. It simply confirms that you are:
- Not fit for work, or
- May be fit for work with adjustments
If stress is affecting your ability to work, you should speak to your GP as early as possible.
How Is Stress-Related Sick Leave Paid in the UK?
Statutory Sick Pay (SSP)
By law, employers must pay Statutory Sick Pay (SSP) to workers who meet the eligibility criteria. SSP is the minimum amount required, although some employers may offer enhanced sick pay through their contract or workplace policy.
Important update: From 6 April 2026, changes introduced by the Employment Rights Act 2025 have made Statutory Sick Pay easier to access and available for workers across the UK.
Key Changes
- Statutory Sick Pay (SSP) is now available to all eligible employees, with the previous minimum earnings threshold removed.
- Payments begin from the first day of sickness absence, with the three-day waiting period no longer applying.
- The amount you receive is calculated as 80% of your average weekly earnings or the standard weekly rate—whichever is lower.
Eligibility criteria
From 6 April 2026, the Employment Rights Act 2025 updated who qualifies for SSP.
You may be eligible if you:
- have started work with your employer (have done some work for your employer)
- inform your employer about your illness within their set deadline (or within 7 days)
- are classed as employed for tax purposes
This includes workers paid through PAYE, such as employees and agency staff. However, those who pay tax through self-assessment (self-employed individuals) are not eligible for SSP.
SSP is administered through your employer and regulated by HM Revenue & Customs.
Many employers offer occupational sick pay, which may be higher than SSP. Check your contract.

Can My Employer Refuse Time Off for Stress?
They cannot unreasonably refuse to accept a valid fit note.
They cannot:
- Dismiss stress as “not serious”
- Force you to take annual leave instead
- Discipline you for certified sick leave
However, employers:
- Can investigate long-term absence
- Can request occupational health assessment
- Can challenge fraudulent absence
If disputes arise, you can seek free advice from ACAS before making a claim.
Unresolved disputes may be taken to an Employment Tribunal. Claims must usually be brought within 3 months less one day.
What If My Stress Is Caused By Work?
If your stress arises from:
- Excessive workload
- Bullying or harassment at work
- Unsafe or high-pressure working conditions
- Lack of reasonable support
Your employer has a legal duty of care under health and safety law.
The Health and Safety Executive provides Management Standards requiring employers to assess and manage workplace stress risks.
Your employer may need to:
- Conduct a risk assessment
- Adjust duties or hours
- Provide support
- Refer you to occupational health

Can You Be Dismissed While Off Sick With Stress in the UK?
Being on stress leave does not automatically prevent dismissal. However:
- Your employer must follow a fair capability procedure under the Employment Rights Act 1996.
- If your stress-related condition amounts to a disability, you are protected under the Equality Act 2010.
This means:
- Employers must consider reasonable adjustments
- They must obtain medical evidence
- They must consult with you before dismissal
Dismissal may still occur in cases of:
- Long-term incapacity
- Genuine redundancy
- Serious misconduct unrelated to illness
But the process must be fair and proportionate.
How Long Can You Be Signed Off Work With Stress in the UK?
A GP can sign you off for days, weeks, or longer depending on medical need. There is no legal limit on how long a stress sick note can last.
However:
- SSP lasts up to 28 weeks
- Long-term absence may trigger capability review
- Employers must consider medical evidence and reasonable adjustments
Step-By-Step: Taking Stress Leave in the UK
- Speak to your GP honestly about your symptoms
- Self-certify for up to 7 days if needed
- Obtain a fit note if absence continues
- Notify your employer according to policy
- Check your sick pay entitlement
- Keep copies of all documentation
