CHECK24 España Reviews 

NizaCars coerced an arbitrary 281.75 € charge at Barcelona Airport, refused to issue a proper itemized invoice (factura), and CHECK24 initially refused to intervene despite clear evidence of predatory counter tactics.

UPDATE 04/09/26: The 150.00 € security deposit (garantía) authorized on my card at the NizaCars terminal was fully released with zero issues or damages. This completely invalidates CHECK24’s original justification for denying my claim. Their support team claimed the 281.75 € forced local insurance was charged because my card "couldn't process the deposit." The successful pre-authorization and total release of the 150 € deposit proves my card was 100% valid for the agreement all along.

UPDATE 09/09/26: Following these updates, my claim has been escalated and is now back under active investigation by CHECK24's support team.

UPDATE 14/09/26: After CHECK24's automated system falsely flagged "missing documents" (a pending photo placeholder), I confronted their support assistant directly:
"Parece que estamos retrocediendo. Adjunto los registros de pago completos y los extractos bancarios exactos que muestran la salida de los fondos de la cuenta. Antes de que podamos dar un paso más, ayúdame a entender: Qué información específica falta y por qué se ha reabierto este reclamo?"

Their support confirmed this was merely an automated system artifact. To leave zero room for delay, I re-uploaded:

The 150.00 € pre-authorization terminal receipt (proving card validity). The 281.75 € charge receipt forced at the NizaCars desk. The official PDF bank statement proving the exact funds leaving my account.

CHECK24 has now officially confirmed that all documentation is complete and the file is in final review. Awaiting their ultimate resolution.

UPDATE 28/09/26: Total operational chaos and contradictory responses from CHECK24.
On one hand, their public PR team replied here claiming my case is being re-reviewed. Then only days later, their support team sent an automated rejection email recycling the generic "debit card" excuse—completely ignoring the terminal receipts and bank statements I uploaded proving that NizaCars successfully pre-authorized and released the €150 deposit on my card at the desk without issue.
If my card processed the deposit fine, the forced €281.75 local charge was purely a counter coercion tactic, not a technical card failure. Which is it, CHECK24? Is a specialized team actually reviewing the evidence, or are these Trustpilot replies just copy-paste damage control while support auto-denies legitimate claims?

They offer a 10% discount on a hotel booking which then becomes a cashback payment that later they explain has to be declared as a taxable payment. So not a discount at all. Getting that cashback is impossible as the IT system is designed to say the IBAN is incorrect when entered correctly and so they say they can't make a payment with an incorrect IBAN. I typed in the correct number several times while speaking on-line to the call centre. The operator does the usual call centre job of listening about the issue, that's what they only do, but offers no practical solution like putting in the IBAN manually. They give no email , only offer the cmsame route via an app that ' purposefully ? ' malfunctions re this issue. Awful service.

The call centre does not facilitate any other option but using a the app which only says your issue has been registered but no opportunity to send the IBAN another way

if I can give them less than 1 star I would I rented a hostel room through them and the hostel declined my entry even tho I talked with them in advance telling Tham that I will come later than expected and the hostel worker said yes then I arrived to the hostel and they said no we cant accept you so I reached the customer service of check24 who was rude and asked meet email them to tell me that they have nothing to do ..... they are a bunch of scammers

I have made a reservation 23rd of June for a Hotel in Tunisia it's been fully paid and confirmed, i received the voucher and the payment confirmation.

When i contracted the hotel they denied any reservation with my name i contacted them several times but they didn't receive any reservation, i came back to Check24 and i sent them many emails (6 emails) and i haven't received a single reply, they only reply through their ai agent which doesn't offer any help just a basic FAQ

I need help weather to confirm my reservation or cancel it urgently !!!

We rented a car from FunchalDrive / AutoUnion in Madeira and the experience was very bad. They gave us a vehicle that already had damage and previous issues, and now they are trying to charge us for damages that we did not cause. We consider the treatment unfair and unprofessional. We recommend carefully ,,,,,
Alquilamos un coche en FunchalDrive / AutoUnion en Madeira y la experiencia fue muy mala. Nos entregaron un vehículo que ya tenía daños y problemas previos, y ahora pretenden cobrarnos por desperfectos que no hemos causado nosotros. Consideramos que el trato ha sido injusto y poco profesional

Not given me the car, terms and conditions are dudable.

Arrive with virtual credit card they didn’t allow me

Reply with an email, they never answer.

Horrible experience and customer service, 0% flexible and helping customers with doubts

Not recommended by any case.

When you pay forget about your money if there is any issue they will never het in charge

When hiring a car through this website it gave me the impression that I bought a full coverage insurance. When I got in touch with the actual car hire company they told me that whatever insurance I had board their was not relevant for them. Also, check24 did not tell me that I would not be able to hire a car because I only had a debit card. Basically they provided an entirely unnecessary service, provided confusing and unnecessary information and made us almost end up without a hire car. In the end I paid 60% cancellation fee (less than 24h before pick up) for a service that I would not have been able to access in the first place.
Try to book with the actual companies and not to go through intermediaries.

I rented through them without realizing they were just a middleman, as they were the only option available online in that area. I completed the booking online, only to arrive and find out they weren’t the actual rental company.
Because I booked through them, I was required to pay a €1,000 deposit for a small car for just one week because I have rented through them and nkt directly with the rental company . I was then told that if I paid an additional €200 or so on top of what I had already paid, the deposit would be reduced to €350.
So there I was, in the middle of nowhere in Spain, with my 3-year-old toddler and a lot of luggage, trying to decide whether to risk losing €1,000 over a scratch I may not have even noticed, or pay even more just to reduce the risk or loose less .
Absolutely disgusting.

Unethical business .
They offered certain conditions on their website, but once you complete the payment, the characteristics no longer match what was originally advertised. For example, winter tyres suddenly became snow chains.
The process for submitting a claim is painful and ineffective — you are forced to use a chatbot. I even exchanged emails with some of their employees, “expert car rental” according to their business signature, but they simply redirected me back to the chatbot.
The chatbot interprets your inputs incorrectly and does not respect the literal meaning of your words. The space provided has a character limit that is clearly insufficient to properly describe your issue, and you cannot attach any documents to support and prove your claim.
On top of all that, they do not respond to claims.
NEVER AGAIN.

Never again will I use them.

I booked 2 cars, cancelled 1 because o needed more days and the attention was completely non-existent when o tried to modify the booking.

On the second booking they kept all my money and I did not get the car be shade I lacked a credit card.

Always go with the car company.

The person I spoke to was very helpful and polite.

Very helpful young man. My Spanish is not good so he translated everything for me. He guided me through the process and secured a good deal for my car insurance.

Quick and easy, and cheapest for me

After going through all the details , I was only offered 1 quote, which is not much of a comparison + said i had to put my phone number in to confirm price(even though it kept saying 100% online) then when i did put number , my only quote disappeared!
This was for a VW T5, which have owned for 5 years, not some exotic sports car + I am a 60 year old man, with excellent insurance history.
Am getting the feeling will be getting lots of marketing emails & calls ! cannot see any other reason for doing this

Please don't book rental cars with Check24!!! The "€0 deductible with 100% refund" is a big lie and won't be refunded in the worst case scenario!!! The insurance company always finds a way/reason in the fine print to refuse to refund the deductible, and Check24 was completely unaccommodating (despite being a customer for years)! In my case, it was €2,400, and I went to a lawyer. Unfortunately, Check24 seems to be untouchable as an intermediary and can do whatever they want!
I can only recommend booking directly with the rental car company and taking out insurance with them. Then you'll be better prepared in the event of a claim than with those charlatans at Check24!!!

I booked a 7-seater automatic through Check24 for pickup at Frankfurt Airport, but was initially given a 5-seater, which was far too small for our needs. Unfortunately, the assistance provided was minimal. After raising a significant complaint, they offered a 7-seater manual—which I am unable to drive. Again, support was lacking, and only after escalating the issue further did they locate a 7-seater automatic for us, which required additional waiting. After travelling for 30 hours, this was the last thing we needed. The entire experience was frustrating and stressful due to the poor service, lack of communication, and disregard for customer comfort. While we were waiting, another customer was given a dirty car, and the staff refused to clean or exchange it. Avoid Alamo!

We booked a rental car through Check24 with Hertz at Barcelona Airport. Unfortunately, our flight was delayed, and we realized we might not arrive before the rental counter closed. We tried to contact Check24 at 8:07 PM, just minutes after their customer support line closed at 8:00 PM. There was no emergency contact available, leaving us completely on our own.

We then attempted to reach Hertz directly using the phone numbers provided, but none of them worked. With no way to confirm whether the counter would still be open or if anyone would wait for us, we had no choice but to cancel the reservation. As a result, we lost the booking, were charged a cancellation fee of 35€, and had to spend €100 on a taxi to get home.

The most frustrating part? When we arrived at the airport, the Hertz counter was still open, and staff told us they could have waited for us if we had contacted them. All we needed was one working phone number or any form of support.

This experience showed a total lack of customer care and coordination. One call could have saved the entire situation. Very disappointing service — we cannot recommend Check24 based on this experience

They have finally resolved almost satisfactorily the outstanding issue: refund of cancelled booking. It took a while though.

What remains is the losses caused by uncompleted information in the booking documents. We lost 135€ for that reason, even though the actual cause was Hertz rather than Check24.

We have tried to contact them we got a car of them paid in full then got there and had to pay again and been trying to get it back over 1000 dollars and they are wiping their hands not doing nothing about it so be carefull

I am expat living in Spain, and I always have caveats to try to understand the meaning of legal terms and coverages. I submitted initial quote for car insurance, and after providing my phone number I was immediately contacted by check24 sales rep Olga. She was wonderful in assisting and explaining me all options. She very patiently explained to me what exactly is covered, what counts as a claim, what conditions there are and all the possible processes, very pleased, and if you expat and have questions in regard of anything, try to get OLGA on the phone! :)
