Today’s best Sixt discount codes and deals

Hiring a car can get surprisingly expensive once mileage, insurance and airport fees start stacking up. Sixt is usually one of the more competitive options for both UK and international rentals, particularly if you book online in advance or take advantage of one of its regular prepaid offers.

From premium BMWs and Range Rovers to practical vans, there are several ways to bring down the overall cost of hiring a vehicle. Here’s everything you need to know.

How we find the best Sixt promo codes

We have an expert consumer team that is dedicated to searching and verifying the best Sixt deals and voucher codes, so you can save on car rentals. Alongside working with Sixt, we search the web ourselves and test all codes before sharing them on this page. As soon as the offer has expired, it is automatically removed from the page.

Ways to save at Sixt in August

Download the Sixt app for exclusive offers

If you rent vehicles fairly regularly, it’s worth downloading the Sixt app before you book. Alongside mobile check-in and booking management, the app is also where some location-specific discounts and app-only promotions appear first.

Students can save 15 per cent on rentals

Sixt currently offers students 15 per cent off eligible rentals through Student Beans. The discount can make a noticeable difference to the cost of longer bookings, particularly during university holidays.

NHS staff and keyworkers can get 10 per cent off

Sixt also offers a keyworker discount, which includes NHS staff. Eligible customers currently receive 10 per cent off prepaid car bookings, although minimum hire periods may apply, depending on the offer. You’ll also need to show a valid NHS or keyworker identification when collecting the vehicle.

Consider the Sixt lucky dip option

If you are not worried about the exact model you drive, Sixt's lucky dip rentals can often have much better value than choosing a specific vehicle when you book.

Instead of selecting a fixed model, customers receive a mystery car on arrival, which can sometimes be from a higher category than expected. Previous upgrades have included premium models from brands such as BMW and Mini, making it a surprisingly popular option for travellers looking to maximise value.

Upgrade to unlimited mileage for longer journeys

Every Sixt rental includes a daily mileage allowance, which is typically around 200 miles per day for many vehicles. If you are planning a longer road trip or travelling across multiple locations, upgrading to unlimited mileage can often work out cheaper than paying excess mileage charges later.

Unlimited mileage packages usually start at around £15 per day, though pricing varies by vehicle and rental location.

Save with airport pickup locations

Sixt operates at major airports across the UK, including Heathrow, Gatwick, Manchester, Edinburgh and Birmingham. In some cases, booking a rental car can work out cheaper and more convenient than paying for long-stay airport parking, particularly for shorter trips.

Many airport branches also offer longer opening hours, express pickup and flexible return options, which can make travelling slightly less stressful during peak periods.

Look at Sixt+ instead of leasing

For longer-term driving needs, Sixt+ offers a flexible alternative to traditional leasing. Customers pay a monthly subscription fee and can swap or cancel vehicles more easily than with standard finance agreements.

Insurance, servicing and maintenance are generally included, which can simplify costs if you only need a vehicle temporarily for work, relocation or extended travel.

Sixt FAQs

Where do I enter my Sixt discount code?

If your Sixt offer includes a promo code, select the “see code” button before heading to the Sixt website. Once you have chosen your vehicle and travel dates, you can usually enter the code during checkout, before payment, to apply the discount to eligible bookings.

What is the best Sixt voucher code?

The strongest Sixt deals often depend on the type of vehicle you are booking. Previous offers have included 10 per cent off prepaid car hire, up to 20 per cent off selected rentals and discounts on multi-day van hire bookings. Airport-specific promotions and app offers also appear fairly regularly throughout the year.

What are the best Sixt van hire deals?

Sixt frequently runs discounts on van rentals, particularly for bookings lasting two days or longer. One of the more common promotions includes about 15 per cent off selected van hire bookings, which can make a noticeable difference on larger vehicles such as Luton vans or long-wheelbase models.

Does Sixt charge young driver fees?

Yes, drivers under 25 are usually charged a young driver surcharge when renting through Sixt. Fees currently start at about £36 per day, though pricing varies by vehicle category and rental location.

What is the Sixt fuel policy?

Sixt generally operates a full-to-full fuel policy. This means you collect the vehicle with a full tank and are expected to return it full to avoid additional refuelling charges.

Does Sixt offer unlimited mileage?

Yes, unlimited mileage upgrades are available on selected bookings for about £15 per day. Standard rentals usually include about 200 miles per day before excess mileage fees apply.
