Fitness Certificate

A fitness certificate is a document issued by a registered doctor confirming you’re medically fit to take part in a stated activity. It’s based on a health questionnaire and clinical review, and it stays valid for 12 months from the date of issue. You’ll use it for things like gym sign-up, fit-to-fly clearance, or getting back to work after illness.

This document isn’t the same as a few other papers people confuse it with. Let’s break down the difference.

Fitness Certificate vs Sick Note vs Sports Fitness Certificate

A fitness certificate confirms you’re able to do something. A sick note does the opposite. It certifies that you’re currently unable to work or carry out normal activities because of illness or injury. Same doctor-issued format, completely reversed purpose.

A general medical certificate is broader still. It confirms your overall health status at a point in time, without necessarily saying anything about your capacity for a specific activity. A fitness certificate is narrower and more useful for a gatekeeper. It answers one question only: can you do this particular thing?

Then there’s the sports fitness certificate, which covers organised and competitive sport, martial arts, contact sports and return-to-play situations. That’s a separate product with its own clinical questions. If your reason for needing a certificate involves a league, a club, a competition or contact sport, that page is the right one, not this one.

Worth noting: a fitness certificate confirms general medical fitness for these activities, but it doesn’t override any specific process an organisation runs on its own. More on that in the next section, because it’s the part most services skip over.

Here’s what most people don’t realize: the doctor who issues your fitness certificate isn’t the one who decides whether an airline, employer or gym accepts it. Each purpose has its own decision-maker, and some of them run a completely separate process you’ll need to know about upfront.

Bottom line: get your fitness certificate online, but always check what the receiving organisation actually needs before you rely on it for something regulated, like employment or air travel.

Your doctor works through a structured health questionnaire covering both general health and anything specific to your stated purpose.

General Health Screening

• Current medical conditions
• Recent illness, injury or surgery
• Current medications
• Family history of cardiac conditions
• Symptoms during physical exertion, such as breathlessness or chest pain

Activity-Specific Considerations

For gym membership and fit-to-fly requests, the doctor looks closely at cardiovascular history and any recent hospital treatment. For return-to-work certificates, the focus shifts to the nature of the illness or injury and whether it affects the specific duties you’ll be resuming.

For recreational diving, the doctor asks about your history of ear and sinus problems, seizures, and cardiac symptoms as part of the questionnaire. This is history-taking, not a physical exam. Most diving training agencies will still want their own medical form completed, often after an in-person assessment, before you dive.

Yes. A fitness certificate issued by a doctor registered in your country, after a proper clinical review, is a valid medical document. Three things make it valid: the doctor is registered to practise, their credentials and registration number appear on the document, and the doctor is licensed to practise where you’re physically located when assessed.

Here’s the part worth being honest about: validity isn’t the same as acceptance. Your certificate can be entirely valid as a medical document while still not satisfying a specific organisation’s own process. Where a statutory route exists, like occupational health assessment in the Netherlands or Germany, or where a body runs its own accreditation scheme, like an airline or a diving agency, that process governs. Check the table in the previous section for exactly who decides in your situation.

Every fitness certificate online includes the same set of fields, so whoever receives it can check exactly who issued it and on what basis.

• Your personal details
• Date of assessment
• Stated purpose of the certificate
• The doctor’s findings and conclusion
• Doctor’s name, registration number and country of registration
• Digital signature from the issuing doctor
• Unique verification reference
• Validity period

The digital signature confirms the document was signed by the named doctor. It doesn’t carry a single universal legal status. Signature law differs by country, so if you need to know how a specific receiving organisation treats digitally signed documents, that’s worth checking with them directly.

One price, no tiers to compare.

• Price: €34.99 per fitness certificate
• Validity: 12 months from the date of issue
• Delivery: PDF by email, typically within 30 minutes
• Refund policy: Full refund if the reviewing doctor declines to issue the certificate

That’s it. No hidden add-ons, no upsells buried in the checkout flow.

Real talk: no online questionnaire-based service can replace every regulated medical process, and pretending otherwise would set you up to fail somewhere important. Here’s exactly where this fitness certificate doesn’t apply.

• Statutory occupational health assessment. In the Netherlands, pre-employment medical examinations are restricted by law to roles with defined medical requirements, such as divers, firefighters, pilots and professional soldiers, and must be carried out by an authorised physician. For most jobs, this kind of examination isn’t permitted at all. In Germany, occupational fitness runs through the company physician, not a general practitioner.
• Airline-specific clearance. Where an airline requires its own MEDIF form or assessment by an aviation medical examiner, our certificate supports that process but doesn’t replace it.
• Italian gym membership. Italian law requires a certificato non agonistico, including a baseline ECG, for gym membership and non-competitive sport. A questionnaire-based certificate can’t satisfy this on its own.
• Diving medicals requiring examination. Where your training agency requires a physical examination and its own signed medical form, our certificate doesn’t substitute for that.
• Competitive sport. For organised or competitive sport, martial arts, contact sports or return-to-play situations, use our sports fitness certificate instead.
• Conditions needing physical examination, imaging or lab testing. Some health questions can’t be answered through a questionnaire alone.
• Cases with insufficient clinical basis. If your answers don’t give the doctor enough to make a safe decision, the certificate won’t be issued.

Every fitness certificate online is reviewed and signed by a doctor registered with a recognized medical regulator in their home country.

• Dr. Sinéad Whelan, IMC registration #114892, Ireland
• Dr. Lukas Brandt, ÄK registered, Germany
• Dr. Camille Dubois, RPPS registered, France
• Dr. Anna Kowalska, NIL registered, Occupational Health, Poland

Dr. Kowalska’s Occupational Health registration is worth flagging here specifically, since it’s directly relevant to return-to-work questions, even though the statutory occupational health route in countries like the Netherlands and Germany still runs through their own designated practitioners for regulated cases.

Every fitness certificate carries a unique verification reference. If you’re an employer, gym, school or airline checking a certificate someone has given you, that reference lets you confirm it was genuinely issued by one of our registered doctors, and that it hasn’t expired or been revoked.

Simply enter the reference number on our verification page and you’ll get an instant confirmation of status, issue date and validity.

Your health information is handled under GDPR, encrypted in transit and at rest. The verification reference on your certificate exposes only the certificate’s status and validity, nothing about the health information behind it.

You can request deletion of your data at any time, subject to the record-keeping periods doctors are required to follow under their own regulatory obligations.
