Certificate security
Every MedicalCert certificate can be checked as genuine
Each certificate is issued with anti-tampering protection and its own verification reference. If your employer, university, airline or insurer wants to confirm the document came from a GMC-registered doctor, they can check it against MedicalCert records. 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.
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.
A real doctor. A real letter.
Every certificate issued through MedicalCert is signed by a GMC-registered GP, the same register your NHS doctor is on. It is a private medical certificate rather than an NHS fit note, so your employer, HR department or university decides whether to accept it. Most employers do, but check your absence policy before you apply.

Everything you need to know
Usually, but it is their decision to make. Certificates issued by MedicalCert are signed by GMC-registered doctors, and GOV.UK guidance tells employers that where they agree, an employee may give another appropriate form of evidence instead of a fit note. That agreement is the employer’s to give, so check your absence policy or ask your HR team before you apply. For the first 7 consecutive calendar days of sickness you can self-certify and need no medical evidence at all.
No. A MedicalCert certificate is a private doctor’s letter for your employer, university or insurer. It is not an NHS fit note. GOV.UK requires a fit note when you claim Employment and Support Allowance and you have been unable to work for more than 7 days in a row, and the same applies to the health element of Universal Credit. For a benefit claim, get a fit note from your GP or from another authorised healthcare professional: a hospital doctor, registered nurse, occupational therapist, pharmacist or physiotherapist.
Most certificates are delivered same day. Requests submitted by 11pm are delivered by 9am the following morning. Once submitted, a GMC-registered doctor reviews your case and issues your certificate to your inbox. If the doctor needs more information from you first, they will contact you before issuing.
If a doctor cannot clinically justify issuing documentation based on the information provided, you will receive a full refund. No questions asked. We only issue certificates where there is a genuine clinical basis for doing so.
Yes. All information is handled in strict accordance with GMC confidentiality guidance and UK GDPR. Your personal and medical details are never shared with third parties and are stored securely with 256-bit SSL encryption.
No. You do not need a prior GP appointment or existing medical records to apply. Our doctors assess your case based on the information and evidence you provide during the online consultation. No appointment needed.
