SIXT UK Reviews 

Car was in excellent condition, friendly, quick and informative handover and return.

Agent in Denver was outstanding. Helped up choose appropriate add-on's ( and stopped us taking unnecessary toll pass for area we wete travelling through). Showed genuine interest in helping us and was real credit to Sixt. Car was excellent and pick up and drop off both straightforward.

Amazing experience hiring from.Girona airport to drive to France. Picked up at the terminal, car was excellent...upgrade was easy and cheap. Staff were outstanding. Communication throughout was excellent and the app made everything really simple. I had to extend the hire by a day, all simple to do. Return was swift and simple. Overall.a brilliant car hire experience.

Smooth experience picking up the car and returning it at Alicante airport. Online check in really helped as we did not have to queue at all.

I hire regularly from Sixt at St Pancras, occasionally Manchester and annually from Pisa Airport. I never have to wait around and the staff are always friendly and efficient wherever I hire from. It’s so hassle free that these days I don’t bother getting quotes from other companies. I may occasionally pay a few quid more but it’s worth it for the standard of service. For example, I recently left my glasses in the car when I returned it to St Pancras. A staff member found them and called me directly before I even got home so I could arrange to pick them up from the office rather than have to go through the pain of dealing with lost property to try and locate them. All the usual caveats apply about taking a detailed video or photos of the car on pickup and drop off to make sure there are no issues about damage, but I’d do that regardless of the company.

Used SIXT twice this year and been faultless both times. The app is great and I really like the photographs included in the pick up instructions. When visiting somewhere new, in my case Munster and Verona, it makes everything feel familiar and super easy.
Used auto check in / out at Munster via QR code and was brilliant.
Used counter check in /out at Verona and the staff were friendly and really helpful.
Will use again.

I am a regular user of Sixt Canary Wharf - always a pleasant experience with these guys. The staff is polite and helpful and you always get the car you book or a free upgrade that’s always a nice surprise! They also have a great range of cars available for hire and there’s 5 star service all the way - the new key pickup service works really well without the need for human intervention and is very helpful when you need to pickup at odd hours. Overall super pleased with the service and ease of usage and will be a returning customer for as long as they continue to maintain these fabulous standards!

A complete con, booked a car for 18 hours at a email quoted price of 203.00 euro, took it back with 202 kms covered and theyve added numerous additional charges and have now taken nearly 400.00 euros off my card. Tyring to sort it out on their messaging service and I am currently 43 messages in and getting nowhere, disgraceful !!!

Great Experience renting from Sixt. Staff on pick up and drop off were extremely friendly and professional.
Car was an absolute delight and checking in on the app was brilliant.

Avoid Sixt — months of stress over a tiny scratch, zero flexibility.

Rented a Corsa from Sixt Cambridge in April 2026. On return, they raised a damage report for a small scratch, charging £916 — independent mechanics quote £100-£200 to fix it.
Months later (now July), still unresolved. No willingness to negotiate despite my independent estimates. The car wasn't properly inspected at pickup either, so there's no way to confirm the mark wasn't pre-existing. I even offered to have the car back to repair it myself and return it — declined.
Raised a complaint with the BVRLA — no help. Now told any independent report must come from a manufacturer-approved garage, costing more than the damage itself. Meanwhile being threatened with debt collection despite the charge being actively disputed.
Disproportionate and frustrating. Photograph every inch of the car at pickup and drop-off if you rent here.

Staff were very friendly and helpful. No pressure selling of additional insurance. Car was is good condition although layer found screenwash was empty. Return process was quick and hassle free

upgraded me to a banging Merc. What's not to love?

Great staff, service, quick process handing the keys and signing out all the paperwork, very clear and concise and I was given an upgrade to a better car which I liked.

If I could give 0 stars, I absolutely would.

In early July, I travelled from London to the Lake District with five friends (six people in total). Because of this, I specifically reserved and fully paid for a 7-seater vehicle over a month in advance to ensure we had the correct car for our trip.

When I arrived at the London St Pancras branch on time at 6:00 pm, I was told that my vehicle had been "upgraded." However, the car they gave me only had five seats. Obviously, this was completely unsuitable for a group of six.

When I questioned this and insisted that I simply wanted the 7-seater I had booked and paid for, the staff eventually admitted that they did not have the vehicle I had reserved. The so-called "upgrade" was simply an excuse because they couldn't provide the car I had paid for.

I asked whether they had any other 7-seater available at the St Pancras branch, and they said no. Instead of taking responsibility, the staff kept making excuses and blamed a colleague who had supposedly planned the vehicle allocation that morning. One staff member even told me that if I wanted to guarantee a specific model, I should have called beforehand to check whether they actually had it. That response was unbelievable.

If SIXT knew they couldn't provide the vehicle I had reserved, why didn't they contact me before I arrived? I had booked over a month in advance and paid in full. It should not be the customer's responsibility to call and check whether the company intends to honour a confirmed reservation.

The staff were rude, dismissive, and showed little interest in finding a solution. Eventually, a member of staff suggested that we travel to Heathrow Airport, claiming they were likely to have a 7-seater available there because they had a larger fleet.

Having no other option, we paid £80 for an Uber and travelled for over an hour to Heathrow. When we arrived, we were told that they also had no 7-seater available. This wasted both our time and money.

As a result, one of our friends had to drop out of the trip because we were unable to find another 7-seater at such short notice. We eventually had to rent a 5-seater from another rental company at almost double the normal price because it was a same-day booking.

To make matters worse, I submitted a formal complaint to SIXT by email but did not receive a proper response. Every time I contacted their live chat for an update, I was simply told to email again because they were experiencing a high volume of enquiries. Weeks later, I was still chasing them for a response.

This was one of the worst customer service experiences I have ever had. SIXT failed to provide the vehicle I had reserved and paid for, failed to communicate with me in advance, wasted hours of our day, cost us additional transport and rental expenses, and then failed to deal with the complaint properly afterwards.

I would strongly advise anyone considering SIXT to think twice. Based on my experience, this company cannot be trusted. I would strongly recommend that everyone stay away unless you want to waste your time and money.

And when things go wrong, their customer service is extremely poor.

CON ARTISTS - I hired a car from Faro airport for a week. During the check in process I was told that there was extra insurance available to cover the excess on my policy at a cost of 38 euros. I agreed this only to later discover it was a daily rate not for the week and I ended up paying treble the price of the original car hire which made no sense at all. I complained and received an email saying they were very sorry and were 'looking into it'.
Despite several emails asking for an update I have been ignored. Appalling service I will never use this company again and I would advise others to do the same.

Easy pick up & drop off with clear instructions & polite, helpful staff. Brand new car - all very straight forward.

Outstanding service despite late arrival at Heathrow- courteous and quick - Audi was ready in 15 mins and at a good price. Return was even quicker - great to have the service AT the airport not like other providers who claim the same and are a bus ride away!

This was my first time renting with SIXT in the UK. Although I had rented cars in the UK from other companies several times without any issues, I was unfamiliar with some of the UK's road charging schemes and local traffic restrictions. Unfortunately, I made a few mistakes during this trip.

I fully accept responsibility for every traffic penalty I received and paid them without dispute.

My disappointment is not with the penalties themselves, but with SIXT's administration fee policy. A separate administration fee is charged for each traffic penalty, regardless of whether SIXT pays the penalty on your behalf or simply transfers liability to you.

I understand that this is stated in the rental agreement. However, I find it unreasonable that every individual penalty results in a separate administration fee.

I contacted customer service to explain my situation and ask whether there was any flexibility. Unfortunately, there wasn't. I was told that the administration fee would only be refunded if the issuing authority cancelled the penalty.

The vehicle itself was in good condition, and the rental process was smooth. My disappointment relates entirely to the administration fee policy and the lack of flexibility shown by customer service.

My advice to anyone considering renting from SIXT is simple: read the rental agreement carefully—especially the section on administration fees. A single mistake can be costly, and multiple traffic penalties will result in multiple administration fees on top of the penalties themselves.

Very good experience renting from SIXT in Estepona. The car options were extensive, the booking process simple and the staff very helpful. I would definitely use again
