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.
Sick Note for PTSD
Post-traumatic stress disorder (PTSD) is a serious mental health condition that develops after exposure to a traumatic event or series of events. It is a recognised basis for a sick note in the UK — a GMC-registered doctor can certify that your PTSD symptoms are preventing you from working, in exactly the same way as any physical illness.
MedicalCert issues PTSD sick notes same day, online, through GMC-registered UK doctors. No GP appointment or waiting room required. Submit before 9pm and receive your certificate the same day.
For general guidance covering the 7-day rule, sick pay, SSP April 2026 changes, your legal rights, and what the certificate contains, see our mental health sick note guide. This page covers what is specific to PTSD.
PTSD Symptoms That Affect Fitness for Work
PTSD affects people in highly individual ways. A doctor assesses not just whether you have a diagnosis, but how your specific symptoms are impairing your ability to do your job. The following are common functional impairments considered in a PTSD fitness-for-work assessment:
Flashbacks and intrusive memoriesInvoluntary re-experiencing of the traumatic event that interrupts concentration, decision-making, or the ability to engage with work tasks.
Hypervigilance and startle responsePersistent state of alertness that makes a normal working environment — including noise, crowds, or open-plan offices — severely distressing or unsafe.
Avoidance of triggersActive avoidance of people, places, conversations, or tasks that trigger traumatic memories — potentially including specific colleagues, workplaces, or job duties.
Sleep disturbance and nightmaresSevere insomnia or recurring nightmares causing exhaustion that makes attendance or safe performance of duties impossible.
Cognitive impairmentDifficulty concentrating, memory problems, and dissociative episodes that impair judgement, communication, and the ability to complete work tasks safely.
Emotional dysregulation and angerIntense emotional responses or irritability — particularly relevant in roles involving public contact, team management, or safety-critical environments.
PTSD caused by a workplace incident: Where your PTSD was caused or worsened by events at work — such as an assault, accident, harassment, or traumatic incident — your employer has an additional duty of care. A sick note documents the incapacity; a separate occupational health referral or legal claim may also be appropriate in these circumstances.
PTSD as a Disability — Your Equality Act Rights
Equality Act 2010 — PTSD as a disability
PTSD commonly qualifies as a disability under the Equality Act 2010 where it has had a substantial and long-term adverse effect on normal day-to-day activities for 12 months or more, or is likely to. This covers difficulties with concentration, travel, social interaction, sleep, and the ability to work. Crucially, the test is about impact, not diagnosis — a formal diagnosis is not strictly required if the functional effects are clearly present.
Complex PTSD and recurring PTSD: Conditions that fluctuate or recur over time still qualify as disabilities if the overall long-term picture meets the test. A period of apparent stability does not extinguish disability status if the condition is likely to recur. Employment Tribunals have consistently held that mental health conditions need not be constant to qualify.
Employer duty once PTSD is disclosed: Once your employer knows, or could reasonably be expected to know, that you have PTSD meeting the disability threshold, they have a legal duty to consider reasonable adjustments and cannot discriminate against you on grounds of your condition. They are also prohibited from disclosing your condition to colleagues without your consent.
PTSD caused by work: Where PTSD has arisen from a workplace incident — bullying, assault, witnessing injury, or other traumatic events at work — this may also engage employer liability under health and safety law, separate from the Equality Act framework.
Reasonable Adjustments for PTSD at Work
A sick note for PTSD can include recommendations for workplace adjustments to support a safe return. ACAS guidance identifies the following types of adjustments as appropriate for mental health conditions including PTSD:
If you need documentation specifically focused on workplace modifications rather than absence certification, a work adjustment certificate provides a more detailed clinical framing for adjustment requests.
