SIXT UK Reviews 

Straightforward pickup and drop off with very helpful and friendly staff. Vehicle was clean and over the two weeks we had the car it did everything very well that we needed it to.

⭐☆☆☆☆

One of the worst customer experiences I have ever had.

I booked and paid for a rental car in advance and arrived at Sixt Victoria Station on time, only to find the office closed. After waiting around 20 minutes, an employee finally showed up while a queue of frustrated customers had already formed behind me.

What happened next was even worse. After making me go through the entire rental process and wasting even more of my time, I was told that they could not give me the vehicle because of alleged issues with my driving licence and my credit score.

This explanation was completely absurd. My driving licence has been clean since 2009, with no penalty points or driving offences, and I have an excellent credit score. To this day, I still have no idea what they were talking about.

If there were genuinely eligibility issues, why accept my booking in the first place? Why take my payment? Why make me travel to the branch, wait outside a closed office, stand in line, and complete the entire process before refusing to hand over the vehicle?

To make matters even worse, I was then told it would take up to 6 days to get my money back. So not only was I left without the car I had already paid for, but Sixt also gets to hold onto my money for nearly a week after failing to provide the service. What a joke.

The result was that I was left without a car, important plans had to be cancelled, and I was put in an embarrassing position because other people were depending on me. An entire day was ruined because of Sixt's incompetence, poor organisation, and complete lack of respect for its customers.

This was an absolutely disgraceful experience from start to finish. I will never use Sixt again and would strongly advise others to avoid this branch if they value their time, money, and peace of mind.

Used the Caledonian Road Branch in London for several years and have generally had a very efficient and helpful service, and I intend to keep using them.

I've been renting from Sixt every month for almost three years, and the experience has been consistently excellent. The booking process is straightforward, the vehicles are always in great condition, and the customer service is outstanding. I highly recommend Sixt to anyone looking for a reliable car rental company.

SIXT Édimbourg airport.
A scandale. The worst agency I have ever seen. The agent told me he was tired of waiting for customers. It was 8:00 p.m. He was upset that I was disappointed because the vehicle he was offering me was smaller than the one I had originally booked. He wanted to give me a more expensive vehicle instead, which I declined. He insisted.
He then became angry and refused to provide me with the vehicle I had initially reserved. He simply canceled my reservation in front of me, telling me I was not nice with him. I had to fight then with sixt to be full refund. Don’t go !!

Un scandale. La pire agence que j’aie jamais vue.
L’agent m’a dit qu’il en avait assez d’attendre les clients. Il était 20h00. Il était contrarié parce que j’étais déçu du fait que le véhicule qu’il me proposait était plus petit que celui que j’avais réservé à l’origine.
Il a alors voulu me proposer un véhicule plus cher à la place, ce que j’ai refusé. Il a insisté.
Ensuite, il s’est mis en colère et a refusé de me fournir le véhicule que j’avais initialement réservé. Il a tout simplement annulé ma réservation sous mes yeux, en me disant que je n’étais pas aimable avec lui.
J’ai ensuite dû me battre avec Sixt pour obtenir un remboursement intégral.
N’y allez pas !

Booked an Audi A2 but made a mistake with location. When turned up the Sixt lady sorted the issue out immediately and resolved it with good humour. We were given a Skoda which was almost brand new. It turned out to be a good option.

I recently hired a car from SIXT in Pula Airport, Croatia and had a really positive experience from start to finish.

The girl at check-in was lovely, friendly, and very professional, making the process smooth and welcoming. The gentleman who showed us to our car was amazing — incredibly thorough and a real credit to the company.

We were pleasantly surprised with a free upgrade, which was a nice bonus and definitely appreciated. The car itself was in great condition and drove well.

Returning the car was quick and hassle-free, and the whole check-out process was very easy. Even better, the deposit was refunded within 48 hours, which was great to see.

Overall, excellent service and a stress-free experience — I’d happily use them again.

Do NOT go near. These guys confirmed my booking and charged my card then tell me they have NO cars. 12 days later and I still haven’t got my money back over $2000 AUD. Now they’re telling me they can’t find my booking with booking number and all provided.

Send these guys broke and send a message to people who steal from everyday people. Useless!

I have been charged from somewhere in Germany in euros, after buying in the UK in sterling. this gives me charges ok my bank account.
Customer service didn't want to know and just said contact the bank hard luck

A faultless experience . Let’s be clear, Sixt are not the cheapest, but you don’t get the ‘insurance-sales’ push at the check-in desk. Staff were exemplary - we even got upgraded - with Mel at Majorca airport. Staff in the car collection point were equally professional. We paid €15 for Sixt to recharge the electric car, and thus returned it with less than 10% charge. I took videos - just in case - of the collection and return of the car, ensured the Sixt returns team acknowledged there were no issues and I paid exactly what was agreed. Highly recommended, and will be using Sixt again for the Belgium Grand Prix in July 2026.

Really bad experience. Was shown around the car by a lovely gent in Barcelona, he ran me through details of the existing damage, on all visible panels, but nothing on the underside of the bumper. I asked if this should be checked, but he said only to worry about visible panels. It was all smooth roads throughout, however a week after returning the car in Bilbao I am hit with a 463 euro bill for 'damage'. Strange, I think to myself. Upon reviewing the images sent over, it is scratches along the underside of the front and rear bumpers, that can only be described as wear and tear, or existing damage from another rental before mine. These marks were not visible unless you lie down under the car and look up at them. I can't fathom how these would have happened on my rental, driving along straight, flat roads. I wasn't to know as I wasn't shown these parts of the vehicle upon the initial inspection and told not to worry about it upon collecting my vehicle. I will never use this company of dishonest crooks again, really sour taste left.

very easy check in and collection via App so no queuing. Easy to find car in car park. Good quality car in excellent condition. Easy return process.

Very professional, car was clean and ready when I arrived, no delays on collection, this is the second time I have booked in the USA and will highly recommend, we will be using again next year.

I received amazing customer service at the SIXT desk at Gare du Nord. It was my first time renting with them and it went so smoothly. Sirine walked us through the process and answered any questions and queries we had. I would definitely recommend SIXT to friends and family!

Have used Sixt numerous times at Faro , they are always excellent

Glasgow staff were awesome as were the office, the manager and her staff in glasgow fully understood my needs and gave me a new Cupra, awesome car.

From start to finish they were great!

Not the best experience with Sixt i have to admit, I am sure most rental companies have similar policies in place but it was the first time I hired a car for overseas travel in Finland and I selected my choice of car and price online. When we arrived at the airport with our documents to collect the car, we realised by the guy on the desk that there was a lot of upselling which we didnt appreciate, we were told we could upgrade our car to something more comfortable on the highway with better fuel economy. We said ok, but went to collect the car and it went from our choice of a Toyota Yaris to a Skoda Octavia estate car! We thought its not necessary to have a car as big as that and asked for the keys to the original car instead which they were happy to do, but it was time and hassle we didnt really need walking to and from the airport terminal to the car park twice over.

The guy also suggested we could prepay fuel which would be at a cheaper rate than that at the fuel pump, which basically meant we didnt need to fill the car up to the max on our return journey. When the bill came through they charged us 66.80 EUR, somehow I dont think it costs that much to fill up a Toyota Yaris! And i know it doesnt because we paid 40 EUR to fill up during our trip and it filled the tank fully, so just another example of an upsell and additional cost.

When we got home, we noticed the original charge we paid initially online was credited and replaced with a new billed invoice which was more expensive than the original charge because of add ons such as a 25 EUR premium location fee, a Vehicle License Fee, which took the total to more than the original charge, hidden fees not appreciated! I also noticed they forgot to remove the car upgrade fee, which when questioned apologised about it and refunded us quickly.

Finally we were unlucky to obtain a car park fine, and Sixt charged us a 40 EUR fee for it, which was basically to email an invoice out, the car park fine fee itself, which we had to pay direct to the car park, not Sixt cost us 6.80EUR, so the 40 EUR fee from Sixt was not welcome either (They also charged that fine twice for some reason as my bank account showed -69 GBP, again when questioned they were quick to resolve and issue a refund for but its just another example of incompetence and hassle you dont really need.

On reflection i wont be using Sixt again because of the price, and upsell, with hidden costs that arent clear at the time of online purchase.

I am extremely disappointed with my experience of Sixt and feel other customers should be aware of what can happen when booking one of their prepaid rates.

I paid approximately €129 for a rental car but had to cancel the booking before collecting the vehicle. Despite never receiving a car, never visiting the rental location and never using any service whatsoever, Sixt refunded only €30 and retained around €99.

Sixt’s position is that this is allowed under their terms and conditions. However, regardless of whether it is legally permitted, I find it very difficult to see how retaining almost 80% of the booking value for a service that was never provided can be considered fair or customer-focused.

The most frustrating part is that the financial penalty bears little resemblance to any actual loss suffered by the company. From a customer’s perspective, it feels as though I have paid a substantial amount of money and received absolutely nothing in return.

Had the consequences of cancelling been made sufficiently clear to me at the time of booking, I would never have chosen this rate. I appreciate that terms and conditions exist, but hiding behind contractual small print to justify retaining such a large sum of money leaves a very poor impression.

Customers should be extremely careful when booking with Sixt and should read every detail of the cancellation policy before committing to a prepaid reservation. My experience has been that a simple change of plans resulted in the loss of almost the entire booking value, despite no vehicle ever being supplied.

Whether this policy is legal or not, it does not feel fair, reasonable or reflective of good customer service. As a result of this experience, I will be taking my business elsewhere in the future.

I have been renting my car 6 monthly period from sixt UK/Nottingham branch and paying around £700 each month.
I am fined from parking companu , it is because I have put my plate number incorrectly by mistake and my fine has been deducted to £20 from £100 which has been found genuine human error. HOWEVER I have been charged extra £40 by sixt under administration fee. This is UNFAIR.
How administration fee can be more expensive than actual fine ? I am not a customer who rents a car in daily. It is totally unacceptable and ridiculous service.
I am changing my rental car company immediately.

They took a £3,000 deposit in case of damage, we returned the car and it was confirmed and signed off that there was no damage and it has now been 27 days and we have chased the company and still not had our money back!!!! If it was the other way round they would have took the money immediately, but when it’s them owing the customer their money back they don’t care. Absolutely terrible.
