Bad clinics are not usually hiding. They are advertising, loudly, and most of what gives them away is visible before you walk in.
What follows is the list our own founders wish someone had handed them. Each red flag comes with the check that settles it, because a warning you cannot act on is just anxiety. Most take under two minutes on a phone.
None of these on its own proves a clinic is dangerous. Three of them together is a pattern, and a pattern is your answer.
1. The registration number is nowhere on the site
Every clinic in Spain that performs a health procedure needs an authorisation from its regional health authority, and it appears in REGCESS, the national register of health centres. Good clinics print that number in the footer or on the legal notice page. It costs them nothing and it settles the question.
The check: search the clinic's name in REGCESS. If nothing comes back under the trading name, try the company name on the legal notice. If nothing comes back at all, stop there. Our step by step guide to checking a Spanish clinic walks through the search screen.
2. The person treating you is never named
Look for a name, a photograph and a specialty. Not "our medical team". Not "our expert practitioners". A name.
A clinic that will not tell you who is holding the needle before you arrive is making a choice, and the choice is not in your favour.
The check: find the name, then search it in the CGCOM medical register or ask the clinic for the número de colegiado and the province it is registered in. Any doctor practising legally in Spain has one and will give it to you without hesitation.
3. The specialty does not match the procedure
Spain has a specific specialist title for cosmetic surgery: Cirugía Plástica, Estética y Reparadora. It takes five years of MIR training after the medical degree. A general practitioner, a dentist or a doctor with a weekend certificate is not that, however the website words it.
Aesthetic medicine, meaning injectables, lasers and skin work, is different. It is not a recognised MIR specialty at all, which is exactly why the title on the door tells you less than the register does.
The check: read our breakdown of Spanish medical titles and match the title to the treatment. If a surgical procedure is being offered by someone without the surgical specialty, that is not a nuance, it is the whole point.
4. A price appears before an examination
Real quotes follow assessment. A number that arrives by WhatsApp before anyone has looked at you is a sales price, not a clinical one, and it will change.
The tell is usually the phrasing. "From €1,900" is marketing. "€1,900 for your case, subject to the surgeon's assessment" is at least honest about the sequence.
5. The discount has a clock on it
"Book today and the price holds." "Three places left this month." "September pricing ends Friday."
Urgency is a sales technique borrowed from ecommerce and it has no clinical justification. Surgery does not have a Black Friday. A clinic that makes you rush is optimising for your impulse rather than your outcome, and the practice is squarely in the territory that Spanish consumer law treats as aggressive commercial practice.
The check: say you want a week to think. Watch what happens to the price and to the tone. That single sentence is the most informative test on this list.
6. The consultation is with a salesperson
In many clinics the first appointment is run by an asesor or patient coordinator. That is normal and often useful for logistics. What is not normal is finishing the process without meeting the person who will treat you.
The check: ask directly. "Will I meet the doctor performing the procedure before the day itself?" No is a red flag. "On the morning of" is a red flag wearing a hat.
7. Nobody mentions what could go wrong
Spanish law is unambiguous here. Ley 41/2002, the patient autonomy act, requires informed consent in writing for surgery and for any procedure carrying appreciable risk, and it requires the information to include foreseeable consequences and risks specific to you.
A clinic that describes only the result is not complying with the law it operates under.
The check: ask for the consent document to take home and read before the day. A good clinic hands it over. A bad one tells you it is standard and you will sign it on arrival.
8. Before and after photos with no conditions attached
Look at the photographs properly. Same lighting? Same angle? Same distance? Same expression? Is the after shot wearing makeup the before shot is not?
Then look for what should be there and usually is not: how long after the procedure, how many sessions, what else was done at the same time.
The check: ask for photographs of the specific doctor's work at three months and at twelve months, on a patient with your starting point. The answer, or the shuffle, tells you what you need.
9. Reviews that all arrived in the same fortnight
A clinic that has been open six years does not receive its first forty reviews in March. Sort by most recent, then look at the reviewer profiles. One review each, no photos, first names only, posted in a cluster, is a purchased batch.
More useful than the average is the response to the bad ones. A clinic that answers a one star review with specifics and an invitation to come back in is behaving like a clinic. One that answers with a legal threat, or deletes and reposts, is behaving like something else.
10. Aftercare is vague, or billed separately
Ask the two questions that matter: who do I call at eleven at night on day three, and what does a revision cost.
The answers should be a phone number and a policy. If revision surgery is billed as a fresh procedure at full price, the clinic has no financial incentive to get it right the first time, and you should price that in.
11. The address is a room, not a facility
Surgery requires an operating theatre, anaesthetic cover and a recovery area, and the authorisation for those units is granted specifically. Aesthetic medicine needs far less, which is why a first floor flat can legitimately host injectables and cannot legitimately host a facelift.
The check: the REGCESS entry lists the authorised units. U.47 is cosmetic surgery, U.48 aesthetic medicine, U.35 anaesthesia. If a clinic is selling you a procedure that needs a unit it does not hold, the register says so in a way the brochure never will.
12. Insurance is a question they deflect
Professional indemnity insurance for the practitioner is a legal requirement, and Real Decreto 239/2026, in force since 1 July 2026, tightened the documentation regional authorities can demand from health centres.
The check: "Which insurer covers the surgeon, and what is the policy limit?" You are not going to verify the policy yourself. You are watching whether the question is routine or awkward.
13. The finance offer arrives before the medical plan
Third party lending is normal and not sinister. What is telling is the order. If someone hands you a credit application before a surgeon has confirmed you are a candidate, the clinic has decided you are buying before deciding whether you should.
Our guide to how the money works in aesthetic clinics covers deposits, non refundable fees and what Spanish consumer law actually says about each.
14. There is no complaints route
Every establishment open to the public in Spain must hold hojas de reclamaciones, the official complaint forms, and must give you one on request. For a health centre, complaints also route to the regional health authority that issued the authorisation.
The check: ask where the hojas de reclamaciones are kept. The answer takes three seconds in a well run clinic. Confusion is its own answer.
The two minute version
If you only do one thing, do this. Open the clinic's website on your phone, find the legal notice, take the company name, and search REGCESS. Then find the doctor's name and search the medical register.
Two searches, four minutes, and you have independently confirmed the two facts that every marketing page in the sector is designed to make you assume.
Everything else on this list is texture. Those two are the floor.
Check the clinic before you book
Every clinic in our directory is matched against Spain's public health registry and every doctor against the official medical register. Search by treatment, by concern or by town.
