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.
Second year running where requested Sports Certificate has been produced promptly in advised timescales.
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.
A cancer support medical letter is a doctor-signed document confirming a cancer diagnosis, treatment status, or the impact of cancer and its treatment on your health and daily functioning — used for employment, insurance, benefits, financial hardship schemes, and other formal purposes. This guide explains when a supporting letter is needed, what it should include, and how to obtain one online, subject to clinical review by a GMC-registered doctor.
People living with cancer frequently need medical documentation for purposes unrelated to their direct clinical care — from applying for benefits and requesting reasonable adjustments at work, to accessing financial support schemes, travel insurance appeals, or charitable fund applications. Obtaining timely documentation from an NHS oncology team can be slow. A private supporting letter from a GMC-registered doctor, based on evidence you provide, can help ensure you get the documentation you need when you need it.
We recognise that navigating a cancer diagnosis alongside administrative and financial pressures is incredibly difficult. MedicalCert aims to make the documentation process as straightforward as possible. If you have questions before applying, please contact us at help@medicalcert.co.uk.
When Is a Cancer Support Medical Letter Needed?
Workplace Support & Absence
- Requesting reasonable adjustments under the Equality Act 2010 (cancer is a protected characteristic from the point of diagnosis)
- Supporting a phased return to work after treatment
- Documenting fitness for work limitations during or after chemotherapy, radiotherapy, or surgery
- Occupational health referral documentation
Benefits & Financial Support
- PIP (Personal Independence Payment) or ESA supporting evidence
- Macmillan or cancer charity hardship fund applications
- Mortgage or loan payment holiday applications due to illness
- Critical illness insurance claims
- Financial services hardship schemes — many banks and lenders require medical evidence
Travel, Housing & Everyday Needs
- Travel insurance documentation — confirming diagnosis date, treatment status, and current health
- Blue Badge application supporting evidence
- Housing priority applications where cancer treatment affects housing needs
- Gym or subscription cancellation due to inability to participate
- Confirming immunocompromised status for employers or venues
Legal Protections for People with Cancer in the UK
Under the Equality Act 2010, cancer is a protected characteristic from the point of diagnosis — meaning you are protected from workplace discrimination from the day you are diagnosed, regardless of whether your condition is currently affecting your ability to work. This has important implications for employer documentation requests:
- Employers are legally required to make reasonable adjustments for employees with cancer
- Dismissal related to a cancer diagnosis may constitute automatic disability discrimination
- Absence caused by cancer and its treatment should be recorded separately from other sickness absence
- You are not required to disclose your diagnosis to an employer — but a supporting letter can facilitate conversations about adjustments without requiring you to share unnecessary clinical detail
A well-constructed medical letter can communicate the nature of your functional limitations and support needs without disclosing more information than you are comfortable sharing.
What a Cancer Support Letter Can Include
The content of a cancer support letter depends on its purpose and what you choose to disclose. Subject to clinical review and the evidence provided, the letter can confirm:
Medical Content
- Diagnosis confirmation (type of cancer, if you wish to disclose)
- Current treatment status — active treatment, in remission, surveillance
- Side effects of treatment affecting daily functioning (e.g. fatigue, neuropathy, immunosuppression)
- Prognosis or ongoing medical needs (where relevant to the purpose)
Impact Statement
- How the condition or treatment affects your ability to work, travel, or carry out daily activities
- Specific workplace adjustments that are clinically recommended
- Expected duration of limitations (if assessable)
- Fitness for specific activities or requirements (e.g. fitness to travel, fitness for work)
You control what information you provide for the review. The letter will only include what is clinically supported by the evidence submitted and what you have indicated is appropriate to share for the letter’s purpose.
How to Get a Cancer Support Medical Letter Online
Decide what the letter needs to confirm
Before applying, think about what the letter is for and what the recipient needs to know. The more clearly you can specify the purpose, the better the reviewing doctor can tailor the letter appropriately.
Gather your supporting documentation
Collect any relevant evidence — hospital letters, oncology reports, diagnosis confirmation letters, or treatment summaries. The more evidence you can provide, the more comprehensive and accurate the supporting letter can be.
Complete the online consultation form
Fill in MedicalCert’s secure consultation form, describing your diagnosis and treatment history, the purpose of the letter, and any specific information the recipient requires. Upload your supporting documents.
GMC-registered doctor review
A GMC-registered doctor reviews your submission with care and clinical thoroughness. Where the evidence supports issuing a letter, it is prepared with the appropriate tone and content for the intended purpose.
Receive your letter by email
Your letter is delivered as a PDF — same day or by 9AM the following morning with the express service.

Apply for Your Letter →Frequently Asked Questions
Can a MedicalCert doctor issue a letter if my oncologist or NHS team already manages my care?
Yes. MedicalCert’s doctors issue letters based on the evidence you provide, which can include letters or reports from your NHS oncology team. The letter supplements — rather than replaces — your NHS care documentation. It is particularly useful when you need supporting documentation quickly for employment, benefits, or financial purposes, and your NHS team is not in a position to provide it promptly.
Does a cancer support letter have to disclose my specific diagnosis?
No. You control what information is included. A letter can confirm that you have a serious medical condition affecting your functioning, without specifying the type of cancer, if that is your preference. The reviewing doctor will write what is clinically supported and appropriate to the stated purpose of the letter.
Can I use this letter for PIP or ESA applications?
A private medical letter can be submitted as supporting evidence alongside a PIP or ESA application. However, DWP assessors carry out their own clinical assessments and the letter should be considered supportive evidence rather than a determinative document. It can strengthen your application by providing clear clinical documentation of your diagnosis and functional limitations.
Can a MedicalCert letter be used for travel insurance claims?
Yes. A letter confirming your diagnosis, current treatment status, and any limitations on fitness to travel can support a travel insurance claim or appeal. Always check your insurer’s specific requirements — some may need their own form completed, which can be uploaded during the MedicalCert consultation process.
Are my details kept confidential?
Yes. MedicalCert handles all medical information in accordance with UK GDPR and clinical confidentiality standards. Your data is processed securely and used solely for the purpose of the medical review and letter issuance.
