This car rental company is a total rip off! I was several hours late for my car pickup in Heathrow so the agent said the car was no longer available. They needed to upgrade me, which I did not want or ask for. My original booking was for 182.82 GBP. The agent reworked my booking at an increased fee of 969.83 GBP. It was late and I was at the airport with two children my wife along with all our bags so I was forced to sign. The business tactics are setup to defraud. I contacted them and they declined to do anything saying I signed. Nice Avoid at all cost as the hassle is not worth the false advertising. read more

I'd give MINUS 5 stars if I could. Most of my reviews are positive (check them); but posting this to help others not get scammed like I did. Picking up went fine; but they subtly rush you through the check out process so that you don't feel the need to take video of every inch of the car before you drive away--BE SURE TO DO THIS! When I returned the car, suddenly they tell me it's damaged and charge me over a thousand dollars for repairs. I fight them on it but they just send me to collections. I sadly realize that getting ripped off by a lower amount is better than getting ripped off by a higher amount and so I negotiate a lesser fee and begrudgingly pay it. But they don't remove the collections notices and so I STILL get them to this day (it's been three months). Oh, and the collections notices are in German, which I don't read. Bottom line: rent from ANYONE else and spend 20 mins to take a full, slow-walk video of the entire inside and outside of the car both when you pick it up AND when you drop it off. Protect yourself from this awful company! I hope this helps somebody. read more

Had I read the previous reviews describing shady practices, I would not have rented here. Unfortunately, I had similar negative experiences including: 1) Choice Upgrade: I made an on-line reservation for a Standard SUV Automatic car. At the service counter, I was told I had reserved a small electric SUV. I informed the agent that was incorrect. He subsequently offered to give me a Standard SUV Automatic. He did not mention there would be an additional charge. 2) Premium Location Fee: There was no mention of this fee when I made the on-line reservation. I was not aware of this fee until I later saw it listed on the Prepayment Invoice that arrived later by email, after I had paid on-line by credit card. In addition, the fee on the Prepayment Invoice had increased even more on the final Invoice for some reason unknown to me. 3) I did agree to the Prepaid fuel option at the service counter. However, I was not quoted an actual charge or even an estimated charge. I paid the requested total of 266.22 GBP at the time of reservation. I was shocked to discover I was charged an additional 195.49 GBP on the final invoice when I had expected only an additional charge for the Prepaid fuel fee that turned out to be 49.20 GBP. I requested a credit for on the SIXT UK website for the Choice Upgrade plus Premium Location Fee. My request was flatly refused. I also must mention that while I was at the service counter, a couple entered the office yelling about fees they had not authorized. Little did I know that I would soon face the same! read more

Fraudulent Charges for Pre-Existing Damage - Completely Unacceptable I am extremely disappointed with Sixt Car Rental. They have attempted to charge me for damage that I did not inflict on a rental car. Despite providing photographic evidence as requested and showing that the large scratch was present before I even stepped foot in the car, they still say that I am responsible for it. This was a rental over three months ago. It is outrageous to expect customers to pay for damage caused by someone else simply because the company can not keep track of their vehicle conditions in a timely manner. How many customers have been charged 800GBP for the exact same scratch on this car? This is a blatant attempt to defraud customers and I will be taking this matter further if it is not resolved immediately. Beware of renting here. read more

Never again !!!!! What a scam. I booked on Expedia and they gave me a slightly different car upgrade for which I was then charged almost double the original fee. Total scam company read more

Sixt is charging me 409.98 pounds for their error. Be careful if you rent a car from Sixt. Video inside and out. The car I rented from Sixt on 10 May 2024 had a missing boot cover when I picked it up. After a transatlantic flight and because I was not familiar with the car, I did not notice. Sixt is now charging me for this item. Sixt ignored my explanation of the situation. I couldn't be more disappointed with this company's behaviour. read more

I rented as I always do through Expedia. Paid for my rental in full, about 4-5 month's prior. Only to arrive and be told that Sixt was out of vehicles that matched my order. They forcing me to pay an upcharge or to terminate my order without refund. Feeling backed into a corner and that I had no choice I paid the upcharge expecting to get some help after the fact. I was then sent a review by Sixt where I was asked if I was offered a free alternative when my vehicle wasn't available. I answered no. Then a representative reached out to me to assist. Two days later nothing has changed and I have now received my final and unchanged invoice charging me almost four times what I paid Expedia. Sixt doesn't care about their customers. I paid $275 to expedia for an economy car. They told me they were out of economy cars and put me in a compact SUV and charged an additional $600! I went from less than $300 to almost $900. NEVER has this happened to me. Rental companies always cover the cost when they are out of a certain vehicle. Sixt is unprofessional and shady. They know you don't have a choice when you've already paid up front. Either never pay upfront so they have no leverage or avoid them entirely. They even violated their own policies in covering the cost when a vehicle isn't available. Terribly unprofessional. read more

Sixt rented me a passenger van with 3 bald tires, which means one of them was already replaced. So they knew that the van had bad tires. And guess what happened? Yep, we had a blow out. It took 5 hours to get a tow truck to take it an hour away to fix it. That's so unacceptable. Who does this? Never again, Sixt. read more

avoid them. Charged more than they should have. Waited 4 hours for a flat tire change. Overall bad experience

Recommend avoiding Sixt and sticking with other brands like Enterprise instead. The company misleads you and aggressively pushes fees and additional services onto you. This is all implicitly encouraged to branch employees since they're paid more as their sales numbers go up, and all they care about is getting a promotion and good reviews. Customer service is also unwilling to help or escalate the issue. Very dishonest practices designed to drain your wallet and wishing you had booked a car elsewhere. read more

I really am a fan of Sixt. They have grown into an international car rental company over recent years and I have rented cars from Sixt in the U.K. U.S.A and Mexico. The cars are all premium quality, normally Mercedes, BMW, Audi or Range Rover, and very competitively priced. This location is inside the Sofitel Hotel that is attached to London Heathrow Airport Terminal 5 and is just a few minutes walk from the Arrivals Hall. Follow the signs for Sofitel Hotel and Sixt very clearly marked. The staff are very friendly and informative and the vehicles parked close by for collection and drop off at the hotel. read more

My customer service rep was Roshan Fernando. He was extremely professional, had all of my information to hand, explained everything clearly, offered me an upgrade and insurance but didn't get pushy when I declined. The same guy called me the night before I was returning the car to make sure I knew where to go and what the process was which I have never experienced before. Honestly it was the best rental car experience I have had at Heathrow since I can remember. I used to use Europcar but found their customer service to be terrible. Not sure if the service was a reflection on the company or Roshan, but I was impressed to enough to give them my business next time. read more

Appalling service at T5 Heathrow. Conned into an upgrade as I was told my car wasn't ready. The hire car lady kept repeating an amount which I said to her "that's reasonable" as she just kept saying the same amount. At no point saying it was per day. It more than doubled my hire costs! She also kept saying it was more economical as it had a better engine. Lie no.2 Finally insult was not giving me the car park exit ticket. Effectively losing me the 40min "gain" she said I was getting. Absolute lying charlatans. Ruined my week away. Do not use. Europcar, Hertz etc at Heathrow have all been better. I least I didn't get conned by them read more

Great cars, sensible prices... have a problem and they'll you in the middle of nowhere! This happened first in France (I put it down to a cultural difference that they gave me a shrug down the phone when our car broke down) then again in England. It was at that point that I realized, this company can not be trusted to look after their customers - even the loyal ones. Don't use this company. read more

If I could give Sixt a zero star rating, I would. We rented a car in London at Heathrow for 4 days. Day 2- flat tire. Day 3- transmission problems and the car died. Left us abandoned. Nobody at any phone number at Sixt would either answer or help. If they DID answer the phone they kept transferring us. When I finally reached someone I was promised a 75% refund since we couldn't use the car for 75% of our days reserved. However they lied and charged the entire amount. I WILL fight this with my credit card. However I don't want anyone else to rent from Sixt and lose vacation time, lose money including having to rent taxis, lose their sanity dealing with Sixt, and most of all experiencing the fear being stranded on the side of the road with elderly parents. Do not rent from Sixt. Horrible cars, the WORST customer service, and financially a scam. read more

Heathrow Sixt is entirely different from others - the only word I can think of is "slimy". A bait and switch situation at time of rental and a parking charge for a violation I had already paid for and provided proof of payment. And now, I can't get any response from my last request to reimburse the violation charge. Just radio silence. Instead of paying $1844 (the booking fee for a five seater) we were told we booked a vehicle the size of a Mini Cooper that could only seat four and they would let us take one of their bigger cars for a reduced rate. Final bill $3277. What could we do? We were on a tight schedule and the car was necessary. We were trapped. In addition, they billed me 120 GBP for a parking violation I had already paid directly to Oxfordshire gov parking in the required amount of 35 GBP. Nice markup, Sixt! And no response on my request for reimbursement. My recommendation for Heathrow Sixt, stay away. Very far away. I will continue to fight this leveraging the social media outlets. Caveat emptor! read more

I hate this company! I never even used their service and they refuse to refund my money! Then they refunded half and then rebilled me. I've reached out to them, but I guess they believe in shady accounting. DO NOT USE THIS COMPANY!!! also, my daughter booked a car, and when she returned it, they claimed she damaged the whole right side. Luckily she had extra insurance. I say Sixt pulled a scam there too. Shady AF read more

Reading some familiar experiences. My husband and I got abandoned by the side of the road by SIXT. We were regular customers. If we could rent through SIXT, we did. Not now. They left us stranded in a foreign country and all they could say was, "it's not our responsibility". They're great until there's a problem, then you're completely on your own. read more

Be careful, I rented a car from Sixt - they gave me a heavily damaged vehicle. I took photos of the damage but they still tried to come after me for 1k. If the car they give you has any damage - reject it rent from the other main companies who have cars that aren't damaged. read more

Best option by far for Terminal 5 care hire. Far better than Avis. They are located right there in T5 (by the Sofitel Hotel) - so not need for a shuttle bus etc. I have NEVER had to wait more than 3 mins to get served. The cars are in good order and they are affordable. They dont fuss about the return either. All round excellence. read more

Used them in Atlanta, Georgia. Great customer services. Upgraded for Mercedes 2017 for$11 per day as they didn't have my category. I am satisfied with their services. They refunded the hold pretty quickly read more

I hired a car from Sixt for a month, was hit while parked in a parking lot, immediately reported the scratch, was told repeatedly by people at Sixt that I would not be held at fault for this because I reported it to the police, etc. Now, six months later, I get a bill for over 500 GBP with two weeks to pay. I will never do business with Sixt again. To be fair, they do pretty much tell you when you rent that unless you spring for their extra insurance (at an extra maybe 20 GBP a day), they WILL charge you 1000 GBP per scratch. So, I guess I came out ahead. read more

Good attitude at picking up the car but very bad experience after returning. Firstly, there is a thin and long scratch on the right back bumper and it is very inconspicuous, when returning, Sixt staff can easily found it without careful checking, such a skilled staff! They asked for the damage repairing fee and fortunately I took photos and it can be found existing already when picking it up. Secondly, there is a dart charge happened when I drove, and later they noticed me to charge 36GBP of admin fee for just 2.5GBP dart charge fee, but I insisted to pay by myself so they refund the admin fee at the end. Finally, I planed to rent a car three weeks originally but considered the car condition, I talked to the supervisor at Healthrow Airport branch about my situation, and he agreed that I can return earlier if I think the car is not suitable with no charge on the rest of the days. Now it has been more than one month since returning, they still haven't refunded and insisted it is non-refundable because of their policy, I tried to contact the superviser to clarify but found the phone numbers are all directing to Sixt customer service only and no ones answers. Do I need to complain to the relevant institutions? read more

We wanted a 9 seater van and that worked out great. Had to wait over half an hour while they cleaned the vehicle, but the people at the desk where friendly. We had a problem with a slow puncture, from the time we got the van. As we were doing a lot of miles, after putting air in every couple of days I called them up. They said someone would be out to fix the problem. A couple of hours later, someone called and said they did not know when they could get to me and could I take it to National. I agreed and took it in. Obviously a tire center want money so they replaced the tire and it was all approved by Sixt. Great I thought. Now, having returned home, I get a letter and they say they will invoice me 125 pounds for the tire and 45 admin fee....really! Having had to spend half a day of my rental, hanging around, to get it fixed, not to mention searching for petrol stations to put more air in the tire, they expect me to pay. The tire already had nearly 25,000 miles on it. Does this seem fair? They say I inspected the vehicle and signed for it, did they expect me to get on the ground and inspected all the tires, or maybe I should have got them to jack it up, so I could see all around them. This is not what I would expect from any professional car rental company. read more

Best car hire by far. Zaneta Czugale, thanks for the help! Enterprise couldn't fulfill our reservation and SIXT totally came through for us!

FRAUD! DO NOT USE THIS AGENCY! This car agency first try to charge us for a scratch on the car after we had returned it and left the country. We pointed out that we were not informed of this at the time of the return of the car. They eventually said oh it was no problem but then we got a US$602 charge on our credit card which we brought to their attention. They then took it off but never explained why it was charged in the first place and the customer service person stopped communicating with me after one e-mail. Now we have two US$90 charges because we supposedly acquired two congestion fee tickets while we were there. I was never told about these type of penalties, what a congestion zone is and where I could and could not go. The new Customer Service person that I am speaking to now told me that that it will take time to process my claim because they have so many complaints to deal with. I guess I can see why. They are committing fraud with my credit card and I guess many others by their own account. I still have not gotten to the bottom of this but I wanted to post this to help others avoid the fraud being committed by this car rental agency. AVOID USING SIXT CARE RENTAL! read more
