Altered or copied documents do not pass that check.
Very happy, I ordered my Medical Certificate in the early morning hours and before noon time of same day I had it on my inbox. Speedy service and they present the health condition precisely, get to the point.
They meet the incredibly fast turnaround stated (certificate/letter sent before 9am the following morning if the doctor feels that a letter/certificate is appropriate) which is incredibly quick and I am really grateful for the help provided!
Very easy and quick to get my certificate. And the certificate was approved from the specific company to travel with my dog. I will use them again. Well done.
Second time using this company and they are fabulous! Always great, fast, friendly service. Highly recommend!
This was my second time using Medical Cert, and once again the service was exceptionally quick and professional. Everything was handled efficiently, with clear communication throughout.
I found the service very straight forward and quick. Exactly what I needed to get my Padi medical form signed before our holiday. Thank you very much.
Process was easy and responses were quick. I would recommend their service.
Fast efficient service for medical certificates. I used the not fit to fly service and was provided with a certificate the next day, the price is very reasonable and enabled a flight credit refund with my airline. Would recommend and would use again if needed.
A fast and efficient service. It wasn't complicated and the Fit-to-fly note was accepted by the Airport without any further questions. Thank you.
Ideal for me, I am looking to get a certificate for some medical issues I have. So this is the perfect solution for me, uploading docs was easy and the forms very straightforward to fill in. Will definitely use them again. Many thanks.
Excellent service. Easy to use and certificate issued in less than 24 hours. £39 as opposed to the £150 my GP charges. Highly recommended.
Quick and reasonably pain-free. Received their standard certificate as well as my requested bespoke certificate, by email, by 9am the following morning. Both completed properly, signed and stamped as required. More expensive than my GP, but infinitely quicker and easier.
One of the best experiences. It's easy to get a GP note.
Excellent. My GP refuses to issue DWP MED 3 Fit Notes to students. MedicalCert were excellent and extremely helpful in providing a necessary certificate. Highly recommended.
You were amazing, you kept me updated and replied promptly to any queries I had. I thank you from the bottom of my heart.
They helped me, they were very professional and nice.
Very pleased. Quick service with very professional letter provided.
Great service, pretty straight forward and easy to use the website.
I was recommended Medical Cert by a friend and was so impressed with the service received. I would recommend using a laptop rather than a phone. Overall a fantastic and fast service.
What Is a Stress Leave Certificate?
A stress leave certificate is a medical document issued by a GMC-registered doctor confirming that work-related stress, burnout, or mental exhaustion has rendered you temporarily unfit for work. It provides your employer with documented medical evidence for your absence, supports your Statutory Sick Pay claim, and records that the time off was medically certified rather than unauthorised.
In the UK, stress leave is not a separate legal category. It falls under standard sick leave. The process and documentation are the same as for any other medical absence. A private stress leave certificate from MedicalCert is signed by a GMC-registered doctor and includes a reference number your employer can verify.
Same day delivery | GMC-registered doctors | Full refund if we cannot issue
If your absence is specifically due to anxiety rather than workplace stress, see our anxiety sick note page.
Can You Be Signed Off Work with Stress in the UK?
Yes. Any GMC-registered doctor can sign you off work with stress if your symptoms are severe enough to impair your ability to do your job. You do not need a formal psychiatric diagnosis. The doctor assesses your current symptoms, including sleep disruption, persistent anxiety, inability to concentrate, emotional exhaustion, and physical symptoms such as headaches or chest tightness, and determines whether those symptoms prevent you from carrying out your normal work duties.
Being "signed off with stress" means a doctor has assessed your condition and issued a medical certificate confirming you are temporarily unfit for work due to stress, burnout, or mental exhaustion. The certificate gives your employer the medical evidence they need to record the absence as authorised sick leave and to process Statutory Sick Pay. It does not by itself guarantee your continued employment, though dismissing an employee for legitimate certified sickness absence carries a real risk of an unfair dismissal claim, and separate protections may apply under the Equality Act 2010.
Who can sign you off with stress?
Three types of doctor can issue a stress leave certificate in the UK. Your NHS GP can issue an NHS fit note (Med3) at no cost, though appointment wait times can run to several weeks. A private GP, either in-person or online, can issue a private medical certificate, typically same day. An online doctor service such as MedicalCert provides the same outcome through an online consultation reviewed by a GMC-registered doctor. An NHS fit note must be accepted by your employer as evidence of incapacity. A private certificate is accepted by most UK employers, but acceptance depends on the employer's own absence policy.
What does your employer see on a stress leave certificate?
The certificate states your name, the dates of absence, the name and GMC number of the issuing doctor, and that you are unfit for work. The clinical reason listed will typically be "work-related stress", "stress and anxiety", or a similar description agreed between you and the reviewing doctor. The certificate does not include details of your consultation, personal circumstances, or specific workplace grievances. Your employer receives only the information necessary to process your absence and Statutory Sick Pay. Under ACAS guidance, you are not required to explain the precise nature of your illness beyond what appears on the certificate.
What Is Work-Related Stress? The HSE Definition
Official HSE definition
"The adverse reaction people have to excessive pressures or other types of demand placed on them at work."
This is the formal definition used by the Health and Safety Executive (HSE), the UK's workplace health regulator. It draws a clear line between normal workplace pressure, which can be motivating, and stress, which is a harmful reaction that occurs when pressure exceeds a person's capacity to cope. Under this definition, work-related stress is always damaging and is a recognised occupational health hazard.
The HSE's Management Standards identify six primary areas of work that, if poorly managed, lead to work-related stress: demands (workload, work patterns), control (autonomy over how work is done), support (from managers and colleagues), relationships (conflict, bullying), role (clarity of responsibilities), and change (how organisational change is communicated). Source: hse.gov.uk/stress
Work-related stress in the UK: the scale of the problem
HSE Labour Force Survey data confirms that work-related stress is the single largest cause of occupational ill health in the UK. The figures below are the most recent published estimates, covering 2024/25 and released in November 2025.
Source: HSE, Health and safety at work: summary statistics for Great Britain, published November 2025, covering 2024/25. An estimated 1.9 million workers reported work-related ill health of all kinds over the same period, and 409,000 of the stress, depression or anxiety cases were new. These figures demonstrate why workplace stress is treated as a serious health and safety risk under UK law, and why employers have explicit legal obligations to assess and manage it.
When Do You Need a Stress Leave Certificate?
The UK rules for stress absence follow the same threshold as all other sick leave.
0-7 calendar days
Self-certification only. Inform your employer you are unwell. Stress is a valid reason. A formal doctor's certificate is not required for this period. You are still entitled to Statutory Sick Pay (SSP) if eligible. All calendar days count, including weekends and bank holidays.
8+ calendar days
Medical evidence is required and your employer can legally request it. MedicalCert provides same-day private stress leave certificates with no GP appointment required. Submit online and receive your certificate same day or by 9AM the next morning.
Self-certification vs private stress leave certificate vs NHS fit note
Three documentation routes exist for stress-related absence. Which one you need depends on how long you are off work and whether you need a formal medical certificate.
| Factor | Self-certification | Private certificate (MedicalCert) | NHS fit note (Med3) |
|---|---|---|---|
| When to use | First 7 calendar days of absence only. No doctor needed | Day 8 onwards, or earlier if employer requests. Also useful when you cannot get an NHS appointment | Day 8 onwards. Issued by your NHS GP |
| How to get it | Inform your employer you are unwell. No form required in most workplaces, though some use a self-certification form (SC2) | Online consultation, no appointment. Complete a form and upload evidence. Certificate issued same day or by 9AM next morning | In-person or phone GP appointment, subject to GP availability |
| Speed | Immediate | Same day or by 9AM next morning | Dependent on GP availability. Can take days to weeks |
| Employer acceptance | Employers must accept self-certification for the first 7 days | Signed by a GMC-registered doctor and accepted by most UK employers. Acceptance is at the employer's discretion under its own absence policy, not a statutory duty | Employers must accept an NHS fit note as evidence of incapacity |
| SSP eligibility | Qualifies for SSP from day one (April 2026 reform) | Can support an SSP claim where the employer accepts it as evidence | Qualifies for SSP |
| ESA / benefits claims | Not accepted for ESA or Universal Credit health element | Private certificates do not satisfy DWP requirements for ESA or Universal Credit health element | Required for ESA and Universal Credit health element |
| Cost | Free | For a fee. Full refund if the GP cannot issue | Free via NHS |
| Workplace adjustments | Does not include clinical recommendations | Can include recommendations for workplace adjustments, phased return, or modified duties | Can include "may be fit for work" with conditions |
Common Causes Covered by a Stress Leave Certificate
The HSE identifies six primary areas of work design that, when poorly managed, contribute to work-related stress. Our GMC-registered doctors assess each case individually against these established frameworks. Where the clinical evidence supports an inability to work, a stress leave certificate can be issued for stressors including:
Unmanageable workload, unrealistic deadlines, chronic pressure beyond your capacity. Corresponds to the HSE Management Standards "Demands" area.
Complete emotional, physical, and mental exhaustion from sustained, unmanaged work stress. Often the end-stage of prolonged excessive demands.
Insufficient autonomy over how, when, or where you carry out your work. Corresponds to the HSE "Control" standard.
Work-related anxiety severe enough to impair daily function and attendance.
Interpersonal situations at work creating a clinically significant stress response. Corresponds to the HSE "Relationships" standard.
Redundancy processes, role changes, or restructuring causing acute stress. Corresponds to the HSE "Change" standard.
Stress manifesting as insomnia, headaches, chest tightness, or exhaustion preventing work attendance.
Stress arising from inadequate workplace support for ADHD, autism, or other neurodivergent conditions.
Stress Leave Certificate vs General Sick Note
Both documents evidence your absence. The key difference is specificity.
🧠 Stress Leave Certificate
- ✔ Specifically addresses occupational stress and its impact on work capacity
- ✔ Can include recommendations for workplace adjustments upon return
- ✔ Supports HR conversations about workload, management, or environment changes
- ✔ May support a case for reasonable adjustments under the Equality Act 2010 if stress has led to a longer-term condition
📋 General Sick Note
- ✔ Confirms absence and fitness for work assessment
- ✔ Suitable for any condition including stress, anxiety, or burnout
- ✔ Commonly requested by employers for absences beyond 7 days
- ✔ Less detailed regarding workplace causation
If you simply need absence documentation for your employer, a standard work-related sick note is appropriate. If your stress has a clear workplace cause and you want that reflected in the documentation, or you need to support a request for adjustments on your return, a dedicated stress leave certificate is more appropriate.
Stress leave vs other types of mental health leave
Stress leave is one of several mental health related reasons for time off work. The right document depends on what is actually keeping you from work. A stress leave certificate is the correct choice when workplace stress, burnout, or mental exhaustion is the primary cause. Where a distinct condition is the reason, a condition-specific certificate is more accurate. Use the table below to identify which applies to you.
| Type of leave | What it certifies | Choose this when |
|---|---|---|
| Stress leave certificate | Unfitness for work due to work-related stress, burnout, or mental exhaustion | Workplace stress is the main reason you are unable to work. You are on this page |
| Depression sick note | Unfitness for work due to clinically significant low mood | Persistent low mood, loss of interest, or hopelessness is the primary issue. See the depression sick note page |
| Anxiety sick note | Unfitness for work due to a generalised anxiety presentation | General anxiety, rather than workplace stress specifically, is impairing your ability to work. See the anxiety sick note page |
| Panic attacks and social anxiety | Unfitness for work due to panic attacks or social anxiety | Acute panic episodes or social anxiety are the main barrier to attending work. See the panic attacks and social anxiety page |
| Burnout sick note | Unfitness for work due to burnout as a distinct presentation | You want documentation framed specifically around burnout, or you need the stress vs burnout distinction explained. See the burnout sick note page |
| Bereavement leave | Unfitness for work following the death of someone close to you | Grief, rather than workplace stress, is the reason for your absence. See the bereavement sick note page |
| Mental health support letter | Documents your condition for adjustments, housing, or benefits. Does not certify time off | You are staying at work but need evidence for reasonable adjustments, a housing application, or ongoing support. See the mental health support letter page |
If more than one applies, choose the document that reflects the primary reason you cannot work. A GMC-registered doctor assesses your case individually and will confirm the most accurate wording for your certificate.
Your Legal Rights on Stress Leave in the UK
Key employment law protections
Equality Act 2010: If your stress has led to a diagnosable condition such as an anxiety disorder or depression with a substantial and long-term effect on daily activities, it may meet the legal definition of a disability, giving you additional protection and entitlement to reasonable adjustments from your employer. GOV.UK Equality Act 2010 guidance
Health and Safety at Work Act 1974: Employers have a legal duty to protect the health, safety, and welfare of employees. This includes mental health and work-related stress. Failure to address known occupational stress hazards may expose an employer to civil liability.
Management of Health and Safety at Work Regulations 1999: These regulations require employers to conduct a "suitable and sufficient assessment" of the risks to employee health, including risks from work-related stress. This is the legal basis for the HSE's stress risk assessment framework.
Statutory Sick Pay (SSP): Following the April 2026 reforms, SSP is payable from day one of absence. The previous three waiting days have been abolished. The current rate is £123.25 per week, or 80% of average weekly earnings, whichever is lower. Stress-related absence qualifies in the same way as physical illness. Many employers offer contractual sick pay above this statutory minimum. GOV.UK SSP guidance
Employment Rights Act 1996: Dismissing an employee solely for taking legitimate, properly certified sick leave, including stress-related absence, carries a significant risk of an unfair dismissal claim. Whether a dismissal is unfair depends on the circumstances and is ultimately a matter for an employment tribunal.
Confidentiality: Your employer cannot contact your doctor without your explicit written consent. Beyond what appears on the certificate itself, you are not obliged to disclose the details of your condition. ACAS guidance confirms that employees are not required to explain the precise nature of their illness to their employer.
This page is general information about UK employment and health and safety law, not legal advice. For advice on your own situation, contact ACAS or a qualified employment solicitor.
For Employers: Managing an Employee's Stress-Related Absence
If an employee has been signed off with stress, employers have specific obligations under UK health and safety and employment law. The following guidance aligns with ACAS recommendations on managing work-related stress absence.
What employers should do when an employee is off with stress
For comprehensive guidance, see the ACAS managing work-related stress guidance and the HSE stress management resources.
How Long Can You Be Signed Off Work with Stress?
There is no legal maximum period for stress leave in the UK. The duration is determined entirely by clinical assessment. Your GP or private doctor evaluates your symptoms, functioning, and recovery trajectory to determine the appropriate period.
Typical stress leave duration by severity
These are general ranges based on common clinical presentations. Your actual leave period depends on individual circumstances.
| Severity | Typical duration | Common presentation | Certificate approach |
|---|---|---|---|
| Acute stress | 1-2 weeks | Triggered by a specific event: workplace conflict, restructuring announcement, or a sudden increase in demands. Symptoms may include sleep disruption, anxiety, and difficulty concentrating. | Single certificate, often sufficient for full recovery with rest |
| Moderate stress | 2-4 weeks | Sustained pressure over weeks or months causing persistent symptoms. Physical manifestations such as headaches, chest tightness, or fatigue are common at this stage. | One or two certificates, may include return-to-work recommendations |
| Severe / burnout | 4-12 weeks | Complete emotional and physical exhaustion. Pronounced cognitive impairment, inability to engage with routine tasks, possible co-occurring depression or anxiety disorder. | Multiple certificates with GP review at each renewal. Phased return often recommended. |
| Complex / chronic | 12+ weeks | Work-related stress has triggered or worsened a diagnosable mental health condition. Ongoing treatment (therapy, medication) and occupational health involvement typically required. | Ongoing certification with specialist input. May meet Equality Act disability threshold. |
Each MedicalCert stress leave certificate covers up to 14 days of absence. If you remain unfit to work when your certificate expires, you can request an extension. The reviewing GP will reassess your case based on your current symptoms and situation.
Following the April 2026 SSP reforms, Statutory Sick Pay is payable from day one of absence at £123.25 per week for up to 28 weeks. After 28 weeks of certified absence, SSP ends, though company sick pay policies may provide longer coverage depending on your employment contract.
Stress Leave in Specific Workplace Situations
The general rules above apply in all cases, but certain workplace situations raise specific questions. Each scenario below provides a standalone answer.
Can I be signed off with stress while on probation?
Yes. Probationary employees have the same right to sick leave and Statutory Sick Pay as permanent staff from day one of employment. Employees with under two years' service have more limited unfair dismissal protection, though dismissal connected to a disability under the Equality Act 2010 is unlawful from day one. Some employment contracts also include specific attendance requirements during probation. If your employer raises concerns, check your contract and contact ACAS for free guidance on your rights.
Can I take stress leave while working my notice period?
Yes. If you are clinically unfit for work due to stress during your notice period, you are entitled to take sick leave and receive SSP in the normal way. Your notice period continues to run while you are off sick. You do not need to extend your notice to make up for the time absent, unless your employment contract states otherwise. A stress leave certificate from MedicalCert can be issued during a notice period in the same way as during any other employment period.
What if I cannot get a GP appointment for stress?
NHS GP appointment waits vary widely by practice and can run to several weeks for a routine appointment. If you need a stress leave certificate and cannot see your GP quickly enough, a private online service such as MedicalCert can issue a same-day certificate following an online consultation with a GMC-registered doctor. Most UK employers accept a private certificate as evidence, though this is at their discretion under their absence policy. You do not need to be registered with the private service as your regular GP.
Am I eligible for stress leave on a zero-hours or part-time contract?
Yes. Following the April 2026 SSP reforms, the previous minimum earnings threshold (Lower Earnings Limit) for Statutory Sick Pay has been abolished. Part-time workers, zero-hours contract workers, and lower earners who previously did not qualify for SSP now do. SSP is payable from day one of absence at £123.25 per week or 80% of average weekly earnings, whichever is lower. Stress-related absence on any type of employment contract is treated in the same way as physical illness. GOV.UK SSP guidance
What happens when my stress leave certificate expires?
If you remain unfit for work when your certificate's coverage period ends, you need a new certificate to continue your authorised absence. Without medical evidence covering the dates, your employer may treat the absence as unauthorised. Each MedicalCert stress leave certificate covers up to 14 days. You can request an extension by submitting a new online consultation. The reviewing GP will reassess your current symptoms and issue a further certificate if clinically appropriate. There is no limit on the number of consecutive certificates you can obtain, provided the clinical basis for each is established at the time of review.
Returning to Work After Stress Leave
A well-managed return reduces the risk of relapse. Your stress leave certificate can include recommendations for workplace adjustments to support your return.
Where your condition meets the Equality Act 2010 definition of disability, your employer has a duty to make reasonable adjustments. Outside that, adjustments fall under their general duty of care and ACAS good practice rather than a legal obligation. A medical certificate recommending specific adjustments strengthens your position in that conversation. Common adjustments include:
If your employer cannot accommodate the recommended adjustments, the certificate may effectively be treated as "not fit for work" for a further period. Consider also a work adjustment certificate if you need formal documentation of recommended modifications upon your return.
Do you need a sick note for a phased return to work after stress?
A phased return to work means gradually increasing your hours or responsibilities over a set period, typically two to four weeks, rather than returning to full duties immediately. Your stress leave certificate can include a recommendation for a phased return, which your employer should consider as part of their duty of care and, where applicable, their Equality Act 2010 obligations.
If you need more detailed documentation for a structured phased return, such as specific recommended hours, duties to avoid, or a weekly progression plan, a separate phased return to work letter provides the level of detail your employer and HR department can use to build a formal plan. This is particularly useful in larger organisations where occupational health, HR, and line management all need a clear framework.
