SIXT UK Reviews 

Excellent service. Hired from Stansted airport. Efficient and cheerful despite issues with the computer system and the car originally allocated not being in the compound. Daytime drop off equally efficient and friendly.

car returned early with a full tank and no damage. 3 weeks later I get charged 123 euro for a 'late return' when I returned a day early. This is fraud and the customer care team were useless and could not provide the evidence to support the charge

I will be doing a fraud claim with my bank. AVOID

I hired a car from SIXT in June whilst visiting relatives in Jersey. The car was excellent and the nicest car I have ever driven. Clean and tidy and went really well, not that you can go fast in Jersey anyway. The check in was super quick and I didn't have to provide proof of my booking only me driving licence and credit card. Couldn't fault it and would highly recommend.

Very easy booking process.
Clear choice of insurance level and cost. Compared to many car hire companies where you have to make sure of the insurance and excess amount at the desk on pick up. Sixt it's clear when you book online.
All cars are new.
Key pick up and drop off was so quick.
Sixt is by far the best choice.

Rent the car for business purposes. First time hiring a car ever and it was a great experience:)Shout out to the reception at Birmingham New Street Station, super helpful and gave clear instructions and support throughout the trip. Even got my car free upgraded! Generally speaking it was a very good experience except they can do better with transparent pricing (the final price is 20% VAT exclusive although the initial online quotation says it was VAT inclusive!) but it is fine as the cost is reimbursed by my company but I would suggest people to double check with the staff to make sure the hiring cost works with their budget.

SIXT in Corsica is a disaster. Given an electric car despite asking for petrol engine. Vehicle provided was completely different to car to that specified on rental agreement with different licence plates. The amount charged was €50 more than the price quoted. On return, they tried to claim for a scratch which was not mentioned at the point of handover - this is a very common complaint from other clients across social media. When I called to complain, I was cut off twice. Having spent 20 mins on hold, you eventually give up. DON'T BOOK with SIXT at Figari Airport if you want an honest and efficient rental car service.

Totally unsupportive, when an extension of our 2 week car hire was required, after a vehicle accident.
Inability to arrange, despite 1 hour via whatsapp with various 'handlers' .. - insisting a redelivery of the vehicle, or appearing at their desk in France, (6.5 hours away), until we asked for a 'station' closer to us, in Girona, where the very helpful young man completed in less than 5 minutes, without our signature or a creditcard.
Will never be requesting their 'services' again, made our break hugely stressful.

We hired their car in groups and caused a scratch. These people were already having our deposit already.

We agreed to pay for the repairs for the scratch but these company will try to charge you 3x the price and their communication skills is very poor especially when you are of color.

Be also worn about those receptionist at airport. Two men

Never book a car with these lots. Had the worst experience after booking a car in Montenegro. Unexpected charges, overcharge fuel even after bringing a half filled car. Just choose another car company. Staff kept us and were playing some kinda games and we almost missed our flights. NEVER!

Worst car rental provider in Podgorica airport!!!Staff were very unprofessional and deceiving. Took money from us without any proper explanation and called the police on us when we were asking questions. One of my worse days in my life…Very racist bunch of staff over there

Booked car rental with sixt at Bristol Airport through booking.com nearly 8 weeks before travel & paid in full. Received confirmation. Received an invitation a couple of days before to "Save time and check in now", which I did. Received confirmation of my upcoming reservation the day before. Arrived at rental desk at airport yesterday only to be told they had no cars available. They offered me a mini cooper, but with 4 people and luggage, a mini cooper was nowhere near adequate. Was told they were sorry but nothing they could do & recommended I phone booking.com and see if they could change me to a different rental company or give me a refund. Booking.com were only able to issue a refund, which could then take 5+ working days to arrive. I then had to hire a car with a different company, not getting the type of car I'd previously hired, and at a cost of over £400 more than with Sixt. What a shameful way to treat customers. If you don't have the cars, don't accept the reservation, and if you do accept then make sure car is there, or a better car is available. Will never rent a car with you again. Do not recommend. First time booker, never again. Out of pocket, let down and a dreadful way to start our holiday.

Follow up on 3/7 contacted sixt customer service direct. Was told "The reservation wasn't canceled. At this moment the reservation still shows active.

When a reservation is confirmed with a wholesaler, we can't process any cancellation.

After reviewing you reservation details we can confirm that even if the vehicle you reserved wasn't available at the branch they offer you different options.

Even if those option weren't to your liking for the space, the reservation wasn't canceled, since as we have mentioned, from Sixt it can be cancelled because it was booked with booking.com.

Because of this, we can't process any compensation from our part."

I have confirmation emails from sixt confirming the reservation. It was sixt who said they did not have the car available. It was sixt who said I had to go elsewhere. If the reservation wasn't cancelled, why don't I have a sixt hire car right now?

Sixt confirmed with booking.com that it was a fleet fail. I heard the girl on the phone from sixt to booking.com saying they had nothing appropriate. I also have an email from sixt confirming the car type I had booked. This is disgraceful customer service.

Used Sixt at Kalamata Airport in Greece. The staff were very friendly, genuine and honest and the car in great condition. A video of the car was filmed in my presence and emailed to me, which I founded very useful and created trust. No problems on return two weeks later and the inspection was honest with no nasty surprises. Highly recommended - this is how car rental should always be.

Details: Tried to book online. £316 quoted but something went wrong on website and email address was wrong- result was charge went through to bank for £316, but I had no booking reference number for a trip at the end of the same week. No real solution provided after ages spent on their chat and email over next 24 hours.

Chat advised I should call service centre, to ensure I did have a booking for the trip. They created me a duplicate booking same car same place same time, but now £350. Eventually after a few days the £316 charge to the bank was cancelled leaving me with a booking for the right car right place and time, but now it was £350 not £316.

Worse, when we went to return car, we went to a petrol station to fill up, but somehow the pump kept clicking to say it was full (I tried more than once and it kept clicking), but when I went to return it they said it was not full and despite me explaining what had happened and showing them the receipt indicating I had tried to fill up but had an issue with the cars filler, they charged me £110 fuel charge! I'd have been fine with the actual fuel, but £110 was a shock! So over £500 for a booking originally advertised at £316. Pretty poor really. On the plus side, car was fine if a bit tatty, and counter staff great.

First time using SIXT and had a great experience. I used the Heathrow Airport branch and pick up and return was very straightforward with good information given. Car was spotlessly clean.

I hired a car that was faulty and the dashboard on the hybrid vehicle went blank (wiring was faulty) and did not display the speedometer or anything on dashboard. I called Sixt and a replacement car was organised at the local Sixt the next day (Sixt booked a like for like car). However, upon arrival I was told that they didn’t have a car for despite Sixt making the booking for me for car replacement. I had to then travel 45 minutes to the next closest Sixt to pick up the car replacement. On top of this the faulty car was due to be picked up at 9am and the company came 1 hour later then agreed pick up time which interfered with hotel check out. It’s been a terrible experience and I am out of pocket with Uber transport to the Sixt sites to collect replacement car. So disappointed and won’t be using Sixt again. I’ve had no apology or reimbursement.

I book for a 10am collect then when I arrived I was told it was 12. I booked online in advance and paid extra for the fully comp insurance. When I arrived I was told I’m not insured and I need to pay 200 deposit, of which I still haven’t had back and more importantly I had to pay for insurance of 210. I didn’t argue about this I was on an urgent trip to see my dying father.
Really poor service and I actually feel like I’ve been robed of 410 pounds. I’ve tried to raise a complaint but it hasn’t gone anywhere and no one has responded.

I hired a Sixt car from Edinburgh for ten days, returning it to the same office. Being located under a shopping mall, the centre was hard to find both for a pedestrian and when returning the car but Sixt instructions were fairly detailed & accurate. On arrival, the agent told me I was getting a bit of a discount for being a returning customer, which was nice as I’ve always found it impossible to formerly register as a Sixt customer, but he reassured me that they do recognise me. He went on to fully describe the two grades of cars available to me that day, the payment process, holding fee routine and options for excess reduction. Being seriously unused to modern cars I also asked him to spend some time demonstrating the most important features of the car, which he did with admirable patience. As it was I didn’t attempt to deal with the excessive number of controls on the screen or steering wheel for fear of provoking unnecessary music that couldn’t be turned off, which was fine as nothing there seemed to be needed anyway (although unfortunately a couple of times during the rental period the heating seemed to come on spontaneously, which was distressing on hot days but went off again after some time with all the windows open.) The agent had said I could call him - or the branch, I’m not sure which - if I needed help along the way but I didn’t do this. One brilliant thing at pickup the agent did for me was, with the help of some plugs & wires I happened to have in my luggage, set up in-car recharging ability for my antique phone, which I really appreciated. The BMW car itself was nice to drive, in perfect condition and refuelling was easy. On return, a helpful agent had time to inspect the car & finalise my rental on the spot. The two best things about the whole rental experience was the first staff member’s friendliness & readiness to explain everything about the rental conditions and especially about the car controls. The other fantastic thing was the usual Sixt predictability of the total final cost: no unexpected little fees - and as usual the temporary holding (security) fee never appeared on my bank account. At the moment I don’t see any reason to ever try any other rental company.

Im very disappointed with this company. I initally wrote a glowing review as we thought the customer service at counter was very helpful n informative. Upon receiving my final bill, we noticed that he charged us for the "free" upgrade! when we were at the counter, he asked us how many people would be in the car, and i said, on our return journey, there would be 4 with 1 or 2 larger luggages.. So he said, oh, let me give you a better car than what you booked! Now, i'm very familiar with car rentals n he said we would do us a favour by giving us a bigger car. He searched around n came up with a nissan xtrail, i said this too big, so he searched again n offered us a mercedes 4wd. and he said, this would be better for u. We were like great, a free upgrade! he smiled and proceeded to get on with the paperwork. I asked him to explain what i'm signing as we're all aware, the prints are small and it's multiple pages. I had insurance, so i knew that if something went wrong, i would be fully covered. So he explained that i should select fuel return empty as their fuel rates are cheaper than outside. I agreed. He then explained that if i went w the auto toll charges, it's more convenient. And I agreed. There was NO mention about the additional rental rates because he's upgraded us. i was with a friend and when i got my final bill with the additional cost of the upgrade, i asked my friend.. did u hear anything about being charged for the upgrade??? No, neither of us heard this. And when i dispute this with SIXT, ofcourse, i signed the paperwork, therefore i will be charged for it.
well, never again will i use them! And i can see fr the reviews here that they are unscrupulous! i dont usually write bad reviews but i feel cheated n i wished i had held back with my good reviews till i got my bill! I even thanked customer service for the FREE upgrade! why didnt he correct me n said, oh no maam.. your upgrade is not free!

Sixt+ subscriber for 9 months, on my third rental. On 8 June 2026 my Volvo XC60 had a blown tyre near Chipping Norton with my two young children in the car. Roadside assistance left us stranded for over five hours with repeatedly broken promises; what eventually arrived was a recovery truck, not the tyre repair I'd been told to expect. I paid around £215 for my own taxi and got home at 01:30; my child missed a school exam the next day.
Sixt apologised and confirmed in writing on 12 June that my taxi cost would be refunded within 7–10 working days. The only thing they have actually done is refund the price difference for downgrading me to a Q3 I never asked for – which was simply correcting an overcharge, not compensation. As of today nothing else is resolved: the taxi has not been paid (no link, no funds), I am still in the downgraded car, every email asking when I'll get the XC60 back has been ignored (15, 18, 19, 23, 25 June), and no compensation has been offered for the ordeal. After 9 months as a customer, a written promise broken and total silence is unacceptable.

I have both a corporate and personal silver account with Sixth. I come online to book a car tonight and it is almost 6x what I paid less than a month ago. £197 is the cheapest car the V40 I had for £54 a day is now £276. what is the point inn having loyalty schemes if you don't offer consistent pricing. This is a company that would rather its cars sat idle than let out.
