SIXT UK Reviews 

Staff at desk on Cork Airport wanted me to pay for more insurance. Told them.i had taken out extra protection gir this 1 day trip. Told me only their insurance covers me.
Still waiting for my deposit release after 4 weeks. 1 day trip car all ok email.the following day accepting car returned in same order 10.miles completed
Absolutely the worst rental.i have ever had. Rude staff looking to line their own pockets with the extra insurance. Bonus? of course. Now the delay. Coincidence,? No bad business

The worst customer care I have ever experienced.
We are a family of 6 (two elderly parents, two young children one of us has a disability) stranded in North wales.
We have made 70+ phone calls and passed from department to department. We’ve send emails. Tried WhatsApp. Tried the chat function. No one can tell us when our replacement car will be here. We have been waiting 23 hours now. Appalling.

Terrible customer service.

I booked a car well in advance but they didn’t have the correct size when I picked it up. Not too much of an issue initially as they offered an alternative. The alternative was smaller so had a lower daily cost associated with it. A refund was agreed to compensate for the price difference, however 7 weeks later and I was still without payment despite numerous chases.

I would avoid this company - there are plenty of other options to choose from

An exceptional team at Rennes airport made our car hire experience very easy. They were knowledgable, professional and courteous. Cannot recommend them enough!

Eventually arrived at Palma airport 12 hours late due to a cancelled flight from the UK, so Just wanted to get to our hotel. Was met by a very 'charming' agent at the SIXT desk, who had lots of sympathy and kind words, which should have been a warning to me. As it was late and with only a few cars left he said he had an upgrade for me, making it sound as though my ordered car was not available, but he never once advised or even showed me the more than doubling of the hire fee or the additional Premium Location fee added to the invoice. This latter item should have been on the pre paid invoice when I booked. Once back from our holiday and noticing the additional fees the support staff I contacted were mildly apologetic, but offered only a 50% refund of the, which having been scammed I find somewhat insulting. Plus to add insult to injury, I am still waiting for the refund. Going forward due to the very dubious sales practice used I will avoid SIXT and suggest others do too

I rented in Croatia (Split - Sibenik). The experience was great. The counter was inside the airport, the wait was 2 minutes, and the car was matched the one I booked online.

The return was very simple, I left the keys in the return box and all was correct on the follow-up email. The best car rental company I used so far.

Used the new automatic check in - worked perfectly and saved a very long queue

Picked up a 'well used' car with many imperfections. That doesn't bother me so long as the car is clean and reliable, which it was.
However, through experience I still took a video and photos before pick up.
When I returned I received an email stating that extra damage had occurred during my rental period. I have evidence showing said damage was pre-existing and sent this to Sixt. A week later still had no confirmation.
Even the supposed top end car hire companies try the same trick.

Simple efficient service. Quick pick up and drop off. Nice car. Competitive rates. Great all round

Was an easy and quick collection however would have liked to be recognised and acknowledged as a long standing loyal customer, having multiple rentals from Sixt even though there are other options available, to be offered complimentary rental upgrades or more competitive rental prices.

Sixt made contact my email and by telephone prior to the car hire. The customer service at the desk was outstanding. Friendly, quick and efficient.

The car was easy to access and immaculate On returning the car, the service was even more impressive. Final invoice and refund of deposit arrived whilst I was sitting in the departure lounge at the airport.

If I read this review I would be suspicious about it. Don't be, it's a truly reflective review based on my individual experience.

Well done Sixt ⭐⭐⭐⭐⭐

The airport service bus at Lyon dropped us outside the SIXT office which was appreciated on a hot day. The staff were very helpful (English speaking) and did not attempt to upsell extra insurances. The Citroen C5 was clean and without scuffs . It was a reasonable drive with economical performance.

We hired from Sixt in Martinique. Excellent service from Frederick and a great car, with an easy and quick handover and handback process. I will definitely hire again when we are next in Martinique

Very slick process at collection and return, no queuing, cars are fresh and spotless, generally good specs. Best bit for me was there’s no hard sell or scare tactics when it comes to insurance and while you assume that smaller local companies look cheaper, the final price you pay is very competitive, used them several times and will likely continue to do so.

Easy in and out. My car was in excellent condition and the location in the Frankfurt Terminal parking lot was helpful. Great service too and was open late.

Avoid at all costs.

My recent rental experience felt alarmingly close to a scam.

No damage occurred during our rental period. When we returned the vehicle, the Sixt representative inspected it, told us everything was in order, and asked me to sign on an iPad. No document was displayed on the screen, and the clear implication was that the vehicle was being returned in the same condition as it had been collected.

Twenty-four hours later, I received an email alleging new damage: a scratch of less than 10cm on the driver's door. The evidence provided was highly questionable, consisting of a close-up image of a scratch and a wider image of the vehicle in which no scratch was visible. Despite my dispute and refusal to accept liability, Sixt charged £795 to my credit card.

When I requested timestamped photographs and proof that the alleged damage related to my rental vehicle, Sixt was unable to provide it. More concerningly, the inspection document I had been asked to sign, without being shown its contents, already contained the image of the alleged damage. At no stage during the return process was this brought to my attention. I consider this a serious misrepresentation of what I was being asked to sign.
Fortunately, I had independent insurance that covered the charge. However, one of the insurer's requirements was a copy of the repair invoice. Despite repeated requests, Sixt refused to provide any documentation evidencing that repairs had been carried out.
I had used Sixt for years and previously trusted the company. Following this experience, and having since learned of a near-identical experience from another customer at Sixt Edinburgh Airport, I have completely lost confidence in their damage claims process.

Based on my experience, I would strongly advise others to rent elsewhere.

Impressed by the positive reviews on this website(SIXT, Birmingham Airport), I decided to make a reservation. I paid online when booking and sent a copy of my driver's license for their verification. Upon arriving at the company to pick up the car, I was informed that the vehicle had no insurance coverage at all and I had to pay an extra £146 on top of the rental fee. That meant £129.95 for the 3-day rental, plus £146.00 for insurance—a total of £274.95 for three days. Furthermore, although I had booked a car at the £40/day rate, the agent tried to offer me a £35/day car, claiming it was an upgrade over the one I had reserved. I pointed out three times that he had entered my address incorrectly into his computer, but he eventually gave up and said it was fine. I decided against taking the car and cancelled the whole thing. I am an experienced bus driver—having worked in London, Birmingham, and Coventry—so I know how these companies operate, but this particular company is full of real scammers. Be careful; once you arrive in Birmingham, you might find yourself forced to pay extra money with no other options available.

I am extremely disappointed with my experience with SIXT.

I had a prepaid booking from 27 July to 2 August for £611. I was only checking the price difference for changing the pickup date by one day. During the process, the app became unresponsive, and my booking was unexpectedly modified. The total price increased to £705, an extra £94.

I contacted customer service immediately and explained that this was not an intentional change. I was not trying to cancel my booking or take advantage of a lower price—I simply wanted my original reservation restored. Unfortunately, my request was repeatedly rejected with generic policy responses, and no one appeared willing to properly review the circumstances or consider a goodwill exception.

What disappointed me most was not just the extra charge, but the lack of flexibility and empathy. As a customer, I expected someone to investigate what happened instead of repeatedly quoting the terms and conditions without addressing my specific situation.

This experience has seriously affected my trust in SIXT. I had planned to use SIXT for future rentals, but after the way this issue was handled, I will think twice before booking again. I hope SIXT improves both its app reliability and its approach to customer service so that genuine mistakes are handled more fairly.

What a fantastic experience in Tiranë (Albania) from start to finish. The team were super friendly and explained everything very clearly. Car was superb and we couldn’t have been happier on our Balkan road trip including Kosovo and North Macedonia. Full deposit return. Many thanks

I've used lots of hire companies over the years and Sixt standout as being the best, most hassle-free provider. They do maybe send one too many emails, and they also like to suggest you have to pay extra for use of CarPlay when making a booking online, when you don't, however, despite those two minor niggles, I would definitely hire with Sixt again. Very impressed, plus I got a free upgrade (from manual to automatic) this most recent time, which was very nice and really improved my overall enjoyment of the vehicle. Thanks!
