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!

Mark K. · 2 months ago

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.

Trianda O. · 3 months ago

Process was easy and responses were quick. I would recommend their service.

Cameron M. · 3 months ago

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.

Katharine H. · 7 months ago

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.

Mick W. · 6 months ago

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.

Nicholas O. · 7 months ago

Excellent service. Easy to use and certificate issued in less than 24 hours. £39 as opposed to the £150 my GP charges. Highly recommended.

Joanna R. · 8 months ago

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.

Will R. · 7 months ago

One of the best experiences. It's easy to get a GP note.

Himanshu T. · 3 months ago

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.

Mental Health Sick Note

A mental health sick note is a medical certificate from a GMC-registered doctor confirming that a mental health condition is affecting your ability to work and certifying a period of absence. Mental health conditions are treated in UK law in the same way as physical illness. Employers should consider valid medical evidence and must not discriminate because of a disability, but workplace absence procedures and evidence requirements can vary.

MedicalCert issues mental health sick notes same day, online, through GMC-registered UK doctors. No GP appointment, no waiting room. Submit before 9pm and receive your certificate the same day — or by 9am the following morning.

Mental Health Conditions Covered

We issue sick notes for a wide range of mental health conditions. Each condition has a dedicated page with specific guidance on symptoms, workplace rights, and how to apply.

  • Anxiety — generalised anxiety, health anxiety, and anxiety-related work absence
  • Depression — clinical depression, low mood affecting your ability to work
  • Stress — workplace stress, occupational stress, being signed off with stress
  • Burnout — emotional exhaustion, detachment, reduced professional performance
  • Panic attacks and social anxiety — panic disorder, social anxiety disorder
  • PTSD — post-traumatic stress disorder following traumatic events
  • OCD — obsessive-compulsive disorder affecting daily functioning
  • Bipolar disorder — manic and depressive episodes affecting work capacity
  • Bereavement — grief, distress following the death of a close person

When Do You Need a Mental Health Sick Note?

0–7 calendar days

Self-certification. You can inform your employer you are unwell without a doctor’s certificate. Mental health is a valid reason. All calendar days count including weekends. Your employer cannot request a sick note for this period.

8+ calendar days

A fit note or private sick note from a GMC-registered doctor is required. MedicalCert provides same-day mental health sick notes — no GP appointment needed. Submit online, receive your certificate by email the same day.

Some employers request documentation earlier than 7 days — particularly where there is a pattern of short-term mental health absences, or where their own absence policy specifies a shorter trigger. A private MedicalCert sick note is fully appropriate in these cases even within the first seven days. You can also apply for a certificate to cover a period of absence that has already begun.


Sick Pay for Mental Health Absence — Including the April 2026 Changes

Statutory Sick Pay (SSP) applies to mental health absence in exactly the same way as physical illness. If you are off sick with a mental health condition and meet the eligibility criteria, your employer must pay SSP.

Current rules (until 5 April 2026)

SSP is payable from the fourth consecutive day of absence. Days 1–3 are unpaid waiting days. You must earn at least £123 per week to qualify. Current rate: £118.75 per week for up to 28 weeks.

New rules from 6 April 2026 (Employment Rights Act 2025)

From 6 April 2026, SSP becomes payable from your first day of absence. The three-day waiting period is abolished. The lower earnings limit is also removed — all employees qualify regardless of earnings. Employees earning below the previous limit receive SSP at 80% of average weekly earnings or £123.25 per week flat rate, whichever is lower. These changes are particularly significant for part-time workers and those in lower-paid roles, who previously received nothing for the first three days of a mental health absence.

Your employer may offer enhanced sick pay beyond SSP under a contractual scheme — check your employment contract. SSP is the legal minimum. If SSP ends after 28 weeks, you may be eligible for Employment and Support Allowance (ESA) — a Med3 note from an NHS GP is required for ESA claims specifically.


Your Legal Rights — Mental Health and Sick Leave


What Your Mental Health Sick Note Includes

Your certificate is issued as a signed PDF, verifiable by your employer via QR code. It includes:

Certificate contents

  • Your full name, date of birth, and contact details
  • Condition confirmed as affecting fitness for work (e.g. “anxiety”, “depression”, “stress and burnout”, “PTSD”)
  • Certified period of absence — from and to date
  • “Not fit for work” or “may be fit for work” with recommended adjustments
  • Recommended workplace adjustments, where included
  • GMC registration number of the signing doctor
  • Unique QR code for employer verification
Important: MedicalCert issues private medical certificates valid for employer sick leave and SSP purposes. We do not issue NHS Med3 Fit Notes. A Med3 is required specifically for government benefit claims such as Employment and Support Allowance (ESA) — for ESA, a Med3 must be issued by your NHS GP or NHS healthcare provider. A private sick note is fully valid for all employer purposes including SSP.

How to Get a Mental Health Sick Note Online — Same Day

1

Complete the online consultation

Describe your mental health condition, current symptoms, how long they have been present, and — critically — how they are preventing you from working. You don’t need a formal diagnosis. Be specific about the functional impact: inability to concentrate, leave the house, manage social interactions, maintain routine, or perform tasks safely. Upload any supporting evidence if available (previous GP letters, prescriptions, referral letters).

2

A GMC-registered doctor reviews your case

One of our experienced GPs reviews your submission the same day and assesses whether your mental health symptoms are impairing your capacity for work. The doctor may contact you for further information before issuing. If the doctor cannot clinically support a certificate, you receive a full refund — no exceptions.

3

Certificate delivered to your inbox

If clinically appropriate, your signed certificate arrives same day (submit before 9pm) or by 9am the following morning. Forward it directly to your employer, HR, or payroll team. The embedded QR code allows your employer to verify the doctor’s credentials and certificate authenticity instantly.

For condition-specific guidance including legal frameworks, symptoms, and return-to-work information, see the dedicated pages below.


Mental Health Sick Note FAQs

Yes. Mental health conditions are treated in UK law the same as physical illness. Any mental health condition that affects your fitness for work — including anxiety, depression, stress, burnout, PTSD, OCD, bipolar disorder, and others — is a valid basis for a sick note. You do not need a formal prior diagnosis. The doctor assesses your current symptoms and their functional impact on your working capacity.
No. Your employer is entitled to see the sick note, which will confirm the nature of the condition in general terms (e.g. “anxiety” or “depression”) and how it affects your fitness for work. You are not required to share your consultation content, clinical history, treatment details, or any other medical information. How much you disclose beyond the certificate is entirely your decision. If your condition may qualify as a disability under the Equality Act, you may choose to discuss this with HR to access reasonable adjustments — but this disclosure is voluntary.
There is no legal maximum. Duration is determined by clinical assessment — the severity of your condition and its impact on your ability to work. Fit notes can be issued for a few days, several weeks, or several months depending on clinical need. In the first six months of absence, a fit note can cover up to three months at a time. SSP is available for up to 28 weeks. If you remain unfit after 28 weeks, Employment and Support Allowance (ESA) may be available — for ESA, a Med3 from an NHS GP is required.
No. Under UK law, employers must accept valid certificates from GMC-registered doctors. Mental health conditions must be treated with the same seriousness as physical illness. Refusing a valid mental health sick note could constitute disability discrimination under the Equality Act 2010. The GMC registration number on every MedicalCert certificate allows your employer to verify the issuing doctor’s credentials directly.
Yes, for employment and SSP purposes. A certificate from any GMC-registered doctor is valid for employer absence management, regardless of whether that doctor is NHS or private. The only exception is government benefit claims such as Employment and Support Allowance (ESA), which specifically require an NHS Med3 Fit Note. For everything else — employer absence records, SSP, return-to-work management, HR processes — a MedicalCert private certificate is fully valid and recognised.
A doctor can issue a certificate covering a previous period of absence where the clinical evidence supports it. Supporting documentation such as prescription records, previous GP letters, referral letters, therapy records, or other evidence of your condition during that period strengthens the application. If you have been genuinely unfit for work but have not yet obtained documentation, apply as soon as possible and include any contemporaneous evidence you have.
It may do. A mental health condition qualifies as a disability under the Equality Act 2010 if it has had a substantial and long-term adverse effect on your ability to carry out normal day-to-day activities for 12 months or more, or is likely to. Conditions commonly meeting this threshold include anxiety disorders, depression, bipolar disorder, PTSD, schizophrenia, OCD, and eating disorders. Recurring conditions — where each individual episode is shorter than 12 months but the overall pattern spans 12 months — can also qualify. Where the threshold is met, your employer has a legal duty to consider reasonable adjustments and cannot discriminate against you on grounds of your condition.
Yes. Mental health conditions affecting your ability to study, attend lectures, or meet academic deadlines are valid grounds for medical documentation at university. See our dedicated pages for a university sick note or a student mitigating circumstances letter — both are framed specifically for academic contexts rather than employment, and follow the evidence formats most universities accept.
