I've rented from Sixt a lot and have always had a great experience but Hassan and his team at London Heathrow really redefine excellent service. I had booked a BMW i5 for a recent trip and when I arrived at the airport early they were very apologetic because the car they had put aside for me was not charging. They gave me a plug in hybrid one instead but this wasn't suitable for my trip. I had some issues with the car and their central reservations assured me I could go to Heathrow and pick up an i5. However when I arrived they had no cars. The airport director Hassan gave me his card and put me in a brand new Mercedes, comped my fuel and then said he would deliver the i5 to my hotel and said next time I'm in Heathrow to contact him and he'd make sure my experience was top notch. True to his word he got me my car and comped me my fuel and a little bit more for the trouble. Great service, great cars. I will be back! read more

After extensive research and using Google Gemini AI, Sixt appears to be the only car rental shop directly connected to Terminal 5. And most direct flights from San Diego to Heathrow land in Terminal 5. I also researched other car rental companies, and Sixt prices appear to be about the same overall for upgrading to an automatic transmission(us Americans don't do well with manuals) and for full insurance coverage(American Insurance does not cover foreign rentals). All said and done it was £636/$858 for an Peugeot 2008 SUV with automatic transmission and full insurance coverage. It helped that I made a reservation months in advance. We had a small incident with picking up the car...our flight was an hour early! The 1st Sixt Lady said our car wasn't ready, but we could upgrade for an extra £22/day to pick up a larger SUV, a total of £176/$238! She kept pushing us to upgrade and claimed that the Peugeot 2008 did not have GPS or a center monitor to plug in a iphone with. Very reluctantly and defeated, we agreed as we were exhausted and jetlagged from our 12 hour flight and had no fight left in us. Upon walking to the car lot, we did see a Peugeot 2008 sitting there looking ready. We took a closer look and did see that it did indeed have a center monitor with USB C ports to plug in an iphone. At the pickup office we spoke to the staff, one kind gentleman, a self proclaimed car guy, concurred with me that the Peugeot 2008 did have a USB C port and center monitor to plug in an iphone for GPS, and that the car was ready for rental. I believe his name was Hassan or Anas from my email. He let us test it out, and indeed our iphones were able to connect to connect to the car(fortunately I brought a USC C cable with me!) . Maybe the 1st Sixt Lady at check in did not know her cars? Regardless, we were able to downgrade back to the Peugeot 2008, and get our £176/$238 refunded back to our credit card. It was an annoying 40 minute delay, but it all worked out. Car return was easy as well, just be sure to go to the T5 Sixt Car Rental Return, not the general Car Rental Return center. Almost a 5 star, but I have to mark down due to the snaffu, and I still am annoyed by the $18/day fee to add an additional driver, even for married couples. We skipped that fee, my wife drove the entire time due to that. Will likely rent here again on another UK road trip, despite the annoyances. 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

Shady location. I received a £40 fine from the airport for returning my car incorrectly. Of course, Sixt added their own £40 on top. However, I took PHOTOGRAPHS to PROVE I returned my car correctly. I reached out to Sixt and received a mostly copy/paste response that essentially blamed me. They went on to say I could challenge the fine, but Sixt robbed me of that option, as the fine says you can either pay in full or challenge it. Since, I have received no response whatsoever. I am wholly convinced the manager has a deal with the parking enforcement to rob customers. read more

Worst company ever!! They do the bait and switch, hide charges and lie. They tell you they doing you a favor until you get the printed invoice and the cost on your credit card bill! NEVER RENT FROM HERE! This company sucks!!! read more

I have been a customer of SIXT for 30 years, but must say that they have managed to drive me away completely. In both Germany and in the UK I have found their inability to behave ethically and honestly hugely challenging. They are completely unresponsive, never answer emails and I have spent 6 months both in the UK and Germany trying to get refunds for charges they took off my credit card without my approval, in one case for a incorrect toll payment fine, some 3 years after it was incurred in 2019. So obviously they do not delete your credit card data like they are supposed to, instead hold on on file, probably forever! On top of that they then charged me for it twice!! This is so illegal. If the sums were bigger, I would not hesitate to sue them. I would if it happened in the US. At least here there is accountability. In Europe obviously not! Avoid like the plague. read more

If I could give negative stars I would. 2 hours to pick up a pre booked prepaid rental. Go elsewhere.

Do not rent from this company. Their customer service is non-existent. Since they know none of their customers will return, they gouge every penny out of you. We reserved a Peugot 3008 or equivalent SUV with automatic transmission. On arrival at SIXT the car was not available. After a long discussion, I admitted to being able to drive a standard transmission. We were rented a Skoda octavia estate (station wagon), not an equivalent to the Peugot. While using the car I had a flat tire -- a screw punctured it. I contacted SIXT and a repairman arrived about an hour later and replaced the tire, about a 4-hour job. After returning home I was sent a bill for 138.29 pounds dot the tire including a 45 pound "admin fee." I will never go near SIXT again and highly recommend no one else do so either. read more

I rented a car from Sixt in August 2018 - they gave me an incredibly damaged 4 series despite having booked a 5 series. The car should not have been on the road but they would not change it as they didn't have any of stock. It took over an hour to get the car as there was only 1 employee working and having to deal with returns and new rentals. I documented all the damage to the car which was fortunate as when I returned the car they "found" new damage. This despite not having conducted an inspection at time of rental. Despite a complaint and Sixt admitting fault and errors their damage team tried to charge me. There is currently a complaint in with the BVRLA, I will update with the news. Avoid this company and rent from someone with decent cars. read more

After reading the 1* reviews, I will not be renting from sixt. On line reputation is everything these days and sixt services look unacceptable. Gone should be the days of sharp practice in the car rental sector. read more

Being spoiled by their incredible service in Germany it was a no brainer to book Sixt also at Heathrow. After arrival I got a text with directions where I should go. As Heathrow is such a huge airport Sixt also a few locations depending at which terminal you arrive. If you arrive at terminal 1-4 you will have to take a shuttle bus to Sixt, if you arrive at terminal 5 you will have to walk to the Sofitel Hotel. In this case I arrived at T5 and had to walk to the Sofitel for about 10 minutes. They only have a small counter with only 1 service agent! Luckily there were not many customers so waiting time was short enough. When I checked in the lady told me that I made the reservation for their T1-4 location not T5. Luckily they still had a car for me! So keep this in mind when you make the reservation. You need to know which Terminal you will arrive at! I find this very annoying! Check in was quick, finding the car took long as there are no clear signs and the directions from the service agent were vague! The VW Golf had a build in GPS but the DVD was missing! Wow, they really make you pay for everything. This never happens in Germany! I didn't bother to go back and complain, I just used my smartphone for directions. The car itself wasn't cleaned properly, there was still some garbage left in the car. I was speechless! Returning the car can be challenging, there are not enough Sixt designated spaces and you have to be patient until someone helps you to check the car out. So come early enough! Next time I will definitely rent at Avis which has counters in all arrival halls! read more

SIXT rent a car - Counter - Car Rental Near Me - Hounslow, XGL

Very frustrating experience @ T5. Went to counter in terminal and there was nobody there. No problem, I'll hop on the shuttle to the main office. Got on the shuttle and was turfed off. - 'I cant take you to the office, you have to go to the desk'. - Huh? 'There was nobody there, can't you take me (and my 50Kg of luggage) to the office?'. - 'No! you have to go to the desk' - 'There's nobody at the desk in the terminal' Phone calls were made and I was told to go to the desk in the Sofitel. How am I supposed to know that? There doesn't seem to be any clear signage in T5 only a phone to pick up and presumably be connected to an IVR in a call center. Why would I do that instead of just going to the office? So, haul luggage back to the lift and lug it to the counter in the Sofitel. They don't have my reserved car class 'Were a small satellite office'. You mean as opposed to the main office, the one that has all the cars, that one I was headed towards before I was sent here? So, had to pay to upgrade, surprise... To add insult to injury I was told by the cheery chap at the counter that I could return the vehicle to either the main office or the Sofitel. So why can't I pick up from either? Why is it so hard? Sixt seem to have a persistent problems in this area and it's basic stuff, signage. Atlanta and Heathrow are both very poor in this regard. read more

Many of the problems experienced by travelers arise when car rental companies "discover" damage days after the car has been returned and bill the traveler's credit card for this damage; avoiding these disreputable companies is the best solution. Two days after returning our Sixt rental car to their Heathrow, UK location a 3cm (greater than 1") dent, that damaged the paint, was "discovered". The check-in report when we returned the car did NOT note this dent, nor did it note any new damage or even new scratches. I suspected this company was not quite reputable when a manager (Kirill Ivanov) told me I would have to pay a surcharge of 20 GBP to pick up the car at their Great Southwest Road location - the main Sixt lot you will be bused to from Heathrow Airport- instead of taking the bus from the airport. Car pick up at this premium location already incurs a 97 GBP fee. A few weeks and some e-mails later the 20 GBP surcharge was rescinded. When we picked up the car, a rep told us a single new scratch would cost 150 GBP, so we paid 240 GBP for $0 deductible insurance, bringing the cost of the car to 100 GBP per day - yeah $130/day for the car, insurance, extra driver and a GPS. The insult added to the premium daily rate, is their reaching out and tagging us for damage Sixt and we agree did NOT occur when we had the car. Imagine what would be happening had we not purchased the extra insurance? Will NEVER rent from SIXT again! read more

Surprised by the poor reviews. Our experience was great. They are located right there in T5 so need need for a shuttle bus etc. They were cheaper than Avis who are the only other car rental company actually in T5. Checkin and Check our were easy and smoother. Great car. No issues at all. Highly recommend. read more

First time I used this company. I rented a car from June 3-11. Got a quote expected rental price 160.92 GBP. Just got their invoice and they have charged my credit card 242.76 GBP!! Included in the overcharge is 68.20 GBP prepaid fuel of which I was assured would not be charged on return as I filled it up just before I handed it in. Not amused. I have emailed them but at present I am out of pocket because they cannot get their accounting right. I will use Enterprise as usual next time. Be careful with SIXT if you don't want to be overcharged read more

Never use SIXT while in the UK. My experience first was soured by the incredible lack of service and knowledge at the front desk. They were rude from the moment I approached the desk and extremely slow, considering I had a prepaid car and booking number. While in Edinburgh, my low pressure tire warning light turned on and I immediately called their "customer service" number. After explaining the situation, and the fact that my daughter and I were about to head into a remote part of the Scottish Highlands, the representative said he would send someone to look at the car at our hotel. I was very impressed... UNTIL: I later received a bill, not only for someone coming to look at the tire, but also for a brand new tire! After spending almost an hour discussing this with the customer service agency, they agreed that the tire was not damaged, and also agreed that I had spoken with an agent who approved the onsite visit/repair. However, since I had requested someone to come, and they chose to replace the tire, I was liable. Don't get me started. I have spent too much time fighting them on this. I have now paid the 232,90 GBP for their brand new tire. Incredible! read more
