SIXT UK Reviews 

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!

We are a couple of almost pensioners who booked a SIXT compact SUV to drive 65 miles from the airport to visit our son on a Fri late afternoon and back again on the Sunday evening a couple of days later. Our son drove us in his own car as planned in between. The day after arriving home SIXT took more than double the amount of the original booking from our bank account claiming we had purchased upgrades. We had not and requested a refund of the full difference, evidencing why. Their invoicing demonstrates a catalogue of errors: Incorrect day and time of return (after we were already home !), different prices for different upgrades and wrong mileages. They eventually admitted the mileage and return errors, yet more than a month later haven’t even refunded that part of the overcharge let alone the rest. Their entire case rests on my husband’s signature on the single piece of paper the operator gestured he should sign as he was handed the key. There is nothing written on that sheet of paper referring in any way to us or any contract, or any sign it might have been one page of a document containing more. It is a generic list of countries the hire vehicle we were about to collect is allowed to drive. It doesn’t even have the make or model just the registration.

The staff at SIXT at Belfast City were exceptional
They helped me extend my car rental after my plans changed and went over and above to facilitate the change

From the beginning, the booking of the car and associated bits was easy and I was kept upto date on what vehicle I would have. When collecting the car, Seb (SIXT representative) explained everything thoroughly and made sure I was happy before we left. Returning the car was really easy. The car was clean and tidy when collected. Had no issues at all and would use SIXT again

They gave me the car early as it was convenient for them, then charged me an extra day rental which they refused to credit.

I hired a car from Sixt in Shepherd’s Bush, London, and drove to Stow-on-the-Wold in the Cotswolds. About 30 minutes before we were due to check in to our accommodation, I got a flat tyre.
I opened the boot, removed all our suitcases, and was shocked to discover that there was no spare tyre or tyre repair kit. Sixt had removed both from the vehicle.
What should have been a simple 10-minute delay turned into a five-hour ordeal. I tried calling the customer helpline, but we were in an area with almost no mobile reception. Thankfully, a passing cyclist kindly let me use his phone. Even then, I spent around 10 minutes being transferred between different departments before finally reaching someone who could assist.
Meanwhile, my daughter became increasingly distressed and was in tears after waiting for more than two hours. Despite repeated calls, Sixt still hadn’t arranged for anyone to come and deal with the flat tyre. We were left stranded on the roadside for five hours because Sixt has a policy of removing spare tyres and tyre repair kits from its vehicles. I still have no idea why this policy exists, but it completely disrupted the start of our holiday and caused unnecessary stress and frustration.
What made the experience even worse was Sixt’s customer service afterwards. I lodged a formal complaint and was promised that someone would investigate the incident and get back to me. No one ever did.
When I returned to Australia, I followed up again. The representative admitted they couldn’t explain why the vehicle had no spare tyre or repair kit because they simply didn’t know. Instead of providing answers or taking responsibility, I was offered a credit note towards a future rental. After the way my family and I were treated, I have no intention of renting from Sixt again, so the credit is worthless to me.
This experience ruined the first day of our holiday. The combination of an incomprehensible policy, poor roadside assistance, and unacceptable customer service means I will never use Sixt again and cannot recommend them to anyone.

The pick up and drop off process was very easy and efficient. The car was better than expected, very new and clean. There were no unexpected extra costs added or upsell, which you get with other rental companies. I would definitely use Sixt again.

We've used Sixt for our holiday car rental for 3 years now. They're always reliable, professional and the staff are excellent. This year we hired from Sixt in Pula and had excellent service.

Pick up was expedited and was incredibly efficient. The vehicle allocated was absolutely excellent. Drop off was simplicity itself. Excellent experience.
