FastDoc is the UK's digital healthcare platform providing medical certificates, prescriptions, and specialist referrals from GMC-registered doctors. Below you'll find answers to our most common questions.
General Questions
What is FastDoc?
FastDoc is a UK digital healthcare platform that provides medical certificates, prescriptions (coming soon), and specialist referrals (coming soon) from GMC-registered doctors. We make it easy to get the healthcare documentation you need without waiting for GP appointments - everything is done online and delivered digitally.
Is FastDoc a replacement for my NHS GP?
No, FastDoc is designed to complement your NHS GP, not replace them. We're perfect for getting medical certificates and documentation quickly, but for ongoing health concerns, diagnosis, or treatment plans, you should always consult your NHS GP or visit A&E for emergencies.
Who can use FastDoc?
Anyone in the UK aged 18 or over can use FastDoc services. For certain services like medical letters, we may have specific eligibility criteria which are checked during the online consultation process.
Do I need an account to use FastDoc?
No, you don't need to create an account. You can use our services as a guest, though we'll need your email address to send you the medical documentation.
What services does FastDoc currently offer?
Currently, we offer Medical Letters & Certificates including work sick notes, travel cancellation letters, pregnancy fit to fly certificates, gym cancellation letters, student sick notes, travel with medication letters, and workplace adjustment letters. Online Prescriptions and Specialist Referrals are launching in 2026.
Can I use FastDoc for emergencies?
No, FastDoc is not for medical emergencies. If you have a medical emergency, call 999 or go to your nearest A&E department immediately. FastDoc is designed for non-urgent healthcare documentation needs.
Medical Letters
What types of medical letters do you provide?
We provide 7 types of medical letters: Work Sick Notes, Travel & Holiday Cancellation Letters, Pregnancy Fit to Fly Certificates, Gym Membership Cancellation Letters, Student Sick Notes, Travel with Medication Letters, and Workplace Adjustment Letters. Each is reviewed and issued by GMC-registered doctors.
Are FastDoc medical letters accepted by employers and insurers?
Yes! Our letters are issued by GMC-registered doctors and include full doctor details and GMC registration numbers. They're accepted by employers, travel insurers, airlines, gyms, universities, and institutions across the UK. Each letter is a legitimate medical document.
How quickly will I receive my medical letter?
We offer three service levels: Standard (£24.99) - next day delivery; Same Day (£39.99) - delivered same day if ordered before 3pm Monday-Friday; Priority (£59.99) - delivered in as little as 30 minutes. Most requests are approved within a few hours.
Do I need to speak to a doctor to get a medical letter?
No live consultation is required. You complete a simple online consultation form with your details and medical information. A GMC-registered doctor reviews your submission and issues your letter if it's clinically appropriate. If the doctor needs more information, they'll contact you.
Can I get a sick note for any illness?
We can provide sick notes for most common illnesses and injuries that prevent you from working. However, there are some conditions we cannot cover, particularly those requiring in-person examination or ongoing specialist care. Our online form will check eligibility before you pay.
How long can a sick note be for?
Our sick notes can typically cover periods from 1 day up to 2 weeks. For longer periods, you should see your NHS GP as this usually indicates a more serious condition requiring ongoing medical care.
Will my medical letter be backdated?
We can only backdate letters by a few days and only in appropriate circumstances. The doctor will use their clinical judgement to determine if backdating is appropriate based on your condition and situation.
Can I get a fit note (statement of fitness for work)?
Yes, our work sick notes are equivalent to NHS fit notes (previously called sick notes). They confirm you're unfit for work due to illness and include all necessary information for your employer.
What if my airline doesn't accept the fit to fly letter?
Our pregnancy fit to fly letters meet standard airline requirements and are issued by GMC-registered doctors. If you have specific airline requirements, check them before ordering. In the rare case an airline doesn't accept our letter, contact us at hello@fastdoc.co.uk.
Can I use FastDoc letters for insurance claims?
Yes, our letters are legitimate medical documents issued by GMC-registered doctors and can be used for insurance claims. However, always check your specific insurance policy requirements as some insurers may have particular documentation needs.
Doctors & Medical Safety
Are FastDoc doctors real UK doctors?
Yes, absolutely. Every doctor who reviews cases for FastDoc is a fully qualified medical doctor registered with the General Medical Council (GMC) in the UK. All our doctors have valid GMC registration numbers which appear on every letter they issue.
Can I verify my doctor's GMC registration?
Yes! Every letter includes the reviewing doctor's full name and GMC registration number. You can verify any UK doctor's registration by visiting the GMC website at gmc-uk.org/registration-and-licensing/the-medical-register and searching for their details.
Will I see the same doctor every time?
Not necessarily. Our doctors work on a rota system, so you may see different doctors for different requests. However, all our doctors follow the same clinical standards and guidelines, ensuring consistent quality of care.
What if the doctor doesn't think my request is appropriate?
If our doctor determines that issuing a letter or service isn't clinically appropriate for your situation, they will decline your request and provide an explanation. You'll receive a full refund within 3 business days. Clinical safety always comes first.
Can the doctor prescribe medication through FastDoc?
Not yet. Our Online Prescriptions service is launching in 2026 and will allow GMC doctors to prescribe medication for common conditions. Currently, we only provide medical letters and certificates.
Are FastDoc doctors insured?
Yes, all FastDoc doctors maintain professional indemnity insurance as required by the GMC. This protects both the doctors and patients in their clinical decision-making.
How do doctors review my case without seeing me?
Our doctors review the detailed information you provide in your online consultation form. For medical letters, this is often sufficient as the doctor is confirming information you've provided rather than diagnosing a new condition. If the doctor needs more information or feels an in-person examination is necessary, they'll let you know.
Pricing & Payment
How much do FastDoc services cost?
Medical letters are priced at three service levels: Standard £24.99 (next day), Same Day £39.99 (before 3pm Mon-Fri), and Priority £59.99 (as little as 30 minutes). The same price applies to all letter types within each service level. See our pricing page for full details.
Are there any hidden fees?
No, absolutely not. The price you see is the price you pay. There are no hidden fees, no subscription charges, and no surprise costs. You only pay when you use our services.
What payment methods do you accept?
We accept all major credit and debit cards including Visa, Mastercard, and American Express. Payments are processed securely through Stripe, and we never store your card details.
When do I pay?
You pay when you submit your consultation form. Payment must be completed before a doctor reviews your request. This ensures our doctors can focus on clinical care rather than payment collection.
Can I get a refund if I'm not satisfied?
Yes. If our doctor determines they cannot issue your letter for clinical reasons, you'll receive a full refund within 3 business days - no questions asked. This is our FastDoc Refund Guarantee. However, if you simply change your mind after the doctor has reviewed and approved your letter, we cannot offer a refund as the medical service has been provided.
Do you offer discounts or promotions?
We occasionally run promotions for new customers or specific services. The best way to hear about these is to follow us on social media or sign up for our newsletter. We also offer bundle discounts for businesses - contact hello@fastdoc.co.uk for details.
Can my employer pay for FastDoc services?
Yes, many employers use FastDoc to help their employees get sick notes and other documentation quickly. We can set up corporate accounts and invoicing for businesses. Contact us at hello@fastdoc.co.uk to discuss business solutions.
Why is FastDoc cheaper than other private medical services?
We keep costs down through smart automation and digital-first processes. There's no expensive clinic rent, no reception staff, and no wasted time. Our doctors can review cases efficiently online, and we pass these savings on to you while maintaining high medical standards.
Privacy & Security
Is my medical information kept private?
Absolutely. Your medical information is completely confidential and protected by UK data protection laws. Only the doctor reviewing your case and essential administrative staff (for payment processing and customer support) can access your information. We never share your medical data with third parties.
Is FastDoc GDPR compliant?
Yes, FastDoc is fully compliant with UK GDPR (General Data Protection Regulation) and the Data Protection Act 2018. We maintain strict data protection policies and procedures to keep your information safe and handle it appropriately.
How is my data stored and protected?
All data is encrypted both in transit (when you submit information) and at rest (when it's stored). We use industry-standard security measures including secure servers, encrypted databases, and regular security audits. Access to data is strictly controlled and logged.
Who can see my medical information?
Only the GMC-registered doctor reviewing your case can see your full medical information. A small number of administrative staff may see limited information (name, contact details) for customer support and payment processing purposes. No one else has access to your data.
Can I request a copy of my data?
Yes, you have the right to request a copy of all personal data we hold about you. This is called a Subject Access Request (SAR). Email hello@fastdoc.co.uk with your request and we'll provide your data within 30 days, free of charge.
Can I delete my data?
Yes, you can request deletion of your personal data under GDPR's 'right to be forgotten'. However, we may need to retain certain medical records for legal and regulatory purposes (typically 8 years). Contact hello@fastdoc.co.uk to request data deletion.
Will my GP or NHS be notified?
No, we don't automatically notify your NHS GP or update NHS records when you use FastDoc. Our service is completely separate from the NHS. If you want your GP to know about a medical letter you've received, you'll need to inform them yourself.
Do you use cookies or tracking?
We use essential cookies to make our website work properly (like keeping you logged in). We also use analytics cookies to understand how people use our site so we can improve it. You can control your cookie preferences through our cookie banner. See our Privacy Notice for full details.

It's simple: 1) Choose the service you need from our website, 2) Complete the online consultation form with your details, 3) Pay securely with your card, 4) A GMC doctor reviews your request, 5) Receive your letter via email as a PDF. The whole process takes just minutes.
How will I receive my medical letter?
All medical letters are delivered as PDF documents via email. The email will come from hello@fastdoc.co.uk and include your letter as an attachment. You can download it, print it, or forward it as needed. Make sure to check your spam folder if you don't see it in your inbox.
Can I use FastDoc on my mobile phone?
Yes! Our website is fully mobile-responsive and works perfectly on phones and tablets. You can complete the entire process - from choosing your service to receiving your letter - all from your mobile device.
What if I make a mistake on my form?
If you spot a mistake before submitting, you can go back and correct it. After submission, contact us immediately at hello@fastdoc.co.uk and we'll help. If the doctor hasn't reviewed your case yet, we can update the information. If it's already been reviewed, we may need to process a new request.
I didn't receive my email - what should I do?
First, check your spam/junk folder - sometimes emails from new senders end up there. Also check you entered the correct email address when ordering. If you still can't find it, email hello@fastdoc.co.uk with your order details and we'll resend your letter.
Can I request changes to my letter after it's issued?
Minor corrections (like spelling of your name) can usually be made at no extra cost - just contact us. However, if you need changes to the medical content, dates, or other substantive elements, this may require a new clinical review and payment.
How long are medical letters valid for?
Medical letters are valid for the dates specified on them. For example, a sick note covering 7 days is valid for those specific 7 days. There's no expiry on the document itself - if your employer or insurer needs to see it months later, it remains a valid medical document.
Can I track the status of my request?
Currently, we send you email updates when your request is received, when it's been reviewed by a doctor, and when your letter is ready. If you need a status update between these stages, email hello@fastdoc.co.uk with your order reference.
