Lily had her eye on a midsize saloon hire car for 4 days costing a total of £182.00 at SixT, and had recently received a 10% off voucher code in an email. She had heard rumours of an upcoming 40% clearance sale at SixT and wanted to check the savings she could make on the off chance that they would accept the voucher code on an already discounted product. Lily used our calculator and discovered that by applying both the sale discount AND the voucher together, her basket would drop to just £98.28 - a massive saving of £83.72! The calculator showed her exactly how each discount stacked up and she decided to wait for the sale and see if her dreams would come true! After many good experiences, Lily has trusted PriceDash for many years as her source of validated codes and often visits us when she needs to order from SixT.

It’s worth doing a quick search for SixT promo codes before you book - they really can save you cash. Newsletter sign-ups and student offers are often available, and a good SixT discount code can knock about 10% off a rental, leaving more in your travel pot. Top tip: check for NHS or key worker voucher codes for extra savings in lots of locations.
Voucher codes usually work best when combined with prepay rates or app-only deals, so hunt for offers you can stack. The most useful SixT voucher codes often apply to specific categories, like electric cars or airport transfers, for instant value. Don’t forget to compare promo details and expiry dates so you don’t miss out.
Seasonal SixT deals pop up around long weekends and school holidays, and they can shave a decent chunk off city breaks. Flash sales on SUVs, convertibles and compact cars mean you can find offers that suit your trip and save on the headline rate. Remember that early-bird and advance-purchase promotions usually deliver the biggest percentage cuts.
There are often location-specific offers - cheaper rates in Spain, the US or at Manchester Airport, for example - so search by destination. Many deals include perks like FREE extra driver or upgrade vouchers to boost value without extra spend. Beyond seasonal events, loyalty perks help your savings stretch further with repeat bookings.
Booking a specific category such as electric cars or vans can unlock targeted SixT offers and lower running costs while you travel. Electric car promotions sometimes include FREE miles or reduced excess, and cutting 10–20% off your rental can leave you more relaxed and with extra spending money. Don’t forget that hiring a van or family SUV during off-peak dates usually brings the best per-day rates.
Many travellers save by being flexible with automatic or manual options depending on availability and seasonal demand. Airport transfers and chauffeur services often have separate deals and promo codes that beat regular cab fares. Small extras like pre-booked child seats or GPS in a bundle can be cheaper than adding them later.
Plan around SixT sales events and you can make the most of early-bird or limited-time discounts for major travel seasons. With advance booking windows and flash weekend deals, snagging up to 20% off is realistic and frees up cash for meals or tours. Top tip: set alerts for emails or check aggregator sites the week before your trip.
Lots of people use the pay-later option with a promo to lock in a deal while staying flexible. Cancelling or changing is often straightforward if plans shift, so booking early doesn’t feel risky. Beyond timing, compare branch locations and pickup times to avoid premium airport surcharges.
Joining the loyalty programme is an easy way to save - status tiers unlock upgrades and discounted rates over time. With FREE levels available, even occasional renters can stack rewards and trim costs on repeat bookings, turning small savings into bigger benefits. Don’t forget corporate and student schemes which often mirror loyalty perks for work or study travellers.
Many corporate accounts include flexible payments and a steady 15% discount, which helps small businesses keep expenses down. Platinum or Diamond members often receive guaranteed upgrades or higher discount caps that make frequent hiring worthwhile. Beyond the money savings, loyalty members get faster counters and smoother booking flows that shave hassle off every trip.
Explore Sixt Ride, chauffeur options and car subscriptions to match your travel style while still using SixT promo codes for savings. With car subscriptions you avoid long-term leases and can cancel easily, which helps when plans change or you only need a car for a few months. Little wins like a FREE upgrade or included insurance reduce stress and protect your holiday budget.
Extras such as airport pick-ups, additional drivers or reduced excess cover are usually cheaper when pre-booked and bundled with an offer. App-only discounts or first-ride promotions often give immediate cuts on transfers and chauffeur bookings. Beyond add-ons, sustainability initiatives like electric car incentives sometimes include special voucher codes for greener travel at lower cost.
If you cancel a prepaid SIXT booking before the scheduled pick‑up, there’s a cancellation fee of £99 inclusive of tax. That fee will never be more than the total amount you prepaid. If you cancel after the scheduled pick‑up time, SIXT will charge the full reservation amount. This applies to standard consumer bookings unless your corporate account has different terms.
If you don’t cancel a prepaid reservation before the rental start time and then don’t collect the vehicle, SIXT will charge the full rental amount. The same full‑charge rule applies to cancellations made after the scheduled pick‑up time. So, top tip: cancel before the start time to avoid the full charge. Corporate customers with their own agreements may have different terms.
Pay‑on‑arrival bookings can be cancelled before pick‑up without charge, depending on the tariff you picked when booking. SIXT states that pay‑on‑arrival cancellations before the scheduled pick‑up are usually FREE of charge, but always check your booking confirmation to be sure your tariff is pay‑on‑arrival. Prepaid tariffs follow the prepaid cancellation rules instead.
SIXT doesn’t charge an extra rebooking fee if your change increases the tariff - you just pay the difference. If you chose a pay‑later option, you can make changes at any time with no amendment fee. To change online you’ll need the security code from your confirmation email, or you can contact customer services for help. If a change reduces the price, it’ll be handled according to the original payment and tariff conditions.
SIXT offers pay‑later and pre‑pay tariffs. Pre‑pay bookings are typically cheaper at the point of booking but require payment in advance and may carry fees for cancelling or amending. Pay‑later gives you more flexibility to change without a rebooking fee, depending on the tariff terms. Compare the total price and cancellation conditions before you pick a payment option.
SIXT accepts major credit and debit cards in the UK, including Visa, Mastercard, American Express and Diners Club. PayPal is accepted for prepaid bookings. Cash is not accepted at any SIXT branch in the UK. The cardholder used to pay must be the main driver named on the rental agreement unless corporate arrangements say otherwise.
SIXT doesn’t accept cash, Visa Electron debit cards or prepaid cards such as prepaid Mastercards at UK branches. International debit cards are accepted, but the cardholder must be the main driver when paying. Company credit cards are only accepted if the card shows the name of the renter collecting the vehicle. Check payment terms for any location‑specific restrictions.
The London Congestion Charge is £15 per day if paid in advance or on the same day, according to SIXT guidance. If you pay by midnight of the third charging day after travel, the charge is £17.50. SIXT says it’s the driver’s responsibility to register and pay the Congestion Charge for each day the vehicle is driven in the zone - failure to pay on time may lead to a Penalty Charge Notice issued to the driver.
SIXT notes that some Heathrow branches have no customer parking and that any airport parking or drop‑off fees must be paid directly to the airport. Temporary drop‑off parking for short visits may be managed and charged by the airport. When returning a vehicle, follow the branch return instructions rather than assuming FREE parking is available. Local branch pages will state the exact parking arrangements where applicable.
You can add additional drivers to the rental agreement, but an additional driver fee will apply and is added to the booking price. The exact charge varies by location and rental length, and some vehicle groups already include an extra driver in the price. All additional drivers must be present at pick‑up, show a valid driving licence, and meet age requirements for the vehicle category. Not registering extra drivers can void cover under the rental agreement.
SIXT provides child and baby seats for different age groups, including baby seats (0–13kg), child seats (9–18kg) and booster seats (15–36kg). Seats are checked regularly for quality and include side impact protection where applicable. The site confirms tested seat availability but doesn’t publish a standard price on general help pages, so add the item during booking to see the exact cost. Product descriptions note placement and airbag considerations for front‑seat use.
SIXT charges an administration fee of £40.00 for each traffic‑violation transaction it handles on your behalf. You’ll still be liable for the original fine or penalty amount issued by the authority. This processing charge is listed in the rental information and applies when SIXT handles unpaid tolls, parking fines or other penalties from the rental period.
SIXT includes Loss Damage Waiver (LDW) in its UK rates as standard, which reduces your responsibility for loss or damage to the vehicle subject to an excess. The exact excess depends on the vehicle class and any protection options you choose. Optional products can reduce or remove the excess further - check the rental agreement and protection information at booking to understand potential liabilities.
Drivers under 28 must pay a Young Driver Surcharge according to SIXT’s UK protection information. The exact surcharge is shown on the rental information page and varies by vehicle group and location. Age and licence‑tenure rules also affect eligibility for certain vehicle categories, so check the quoted price at booking for the specific young driver surcharge that applies to you.
If SIXT+ subscribers don’t transmit mileage, an initial processing fee of £9.99 will be charged. If they continue to miss transmissions, the fee rises to £19.99 per month from the second month. This fee structure applies to SIXT+ car subscription customers and is separate from standard rental charges - so remember to transmit mileage via the SIXT app to avoid these processing fees.
