SIXT UK car hire offers and discount codes
Compare a SIXT booking using the exact branch, dates, vehicle category and driver arrangement. A low initial rate is only one part of a suitable rental. Review the complete quote, included services and fare conditions before choosing a promotion.
Promotional rates and member savings
The official UK site displayed a Premium Special offer of up to 15% off when reviewed, for eligible labelled vehicles and rentals of 3–27 days booked by 19 December 2026. Follow the offer route and check the eligible dates, branches and vehicle categories. The maximum reduction is not guaranteed for every quote.
SIXT ONE's researched terms also describe savings of up to 20% for Diamond members. This is a status-specific member benefit, not a public discount for everyone. The member discount depends on the rental and applies to the eligible time-and-mileage base rate, with exclusions for additional services, taxes and other charges described in the programme terms. Other tiers have different entitlements.
How to use a SIXT offer
- Read the promotion and any membership requirement.
- Open the official UK offer route and enter pickup and return details.
- Select the vehicle category and necessary extras.
- Apply an eligible code if the offer supplies one, or sign in for an eligible member rate.
- Check the discount and complete payable quote before confirming.
Do not assume a promotional route combines with a SIXT ONE benefit. Compare the actual booking result rather than adding headline percentages together. No public universal code is supplied for the researched offers.
Compare the practical booking details
Read whether the selected arrangement covers a vehicle category or a guaranteed model. Check passengers, luggage, transmission and essential features together. A pictured example does not automatically establish the exact vehicle supplied.
Review branch hours, collection instructions, payment and deposit requirements, mileage and fuel or charging conditions. Check any terms relevant to the planned route. Compare a one-way booking with another one-way quote rather than a same-branch example, and include necessary optional extras in the total.
Changes and collection
Read the cancellation and amendment terms for the exact rate. Keep the confirmation and required documents accessible. Follow the provider's procedure for recording the supplied vehicle's condition and raise a discrepancy before leaving the branch. Plan the return around the actual branch instructions and keep relevant records.
Shopping questions
Is the Diamond reduction available to new members?
Do not assume so. The relevant status and eligible rate are required.
Is every extra discounted?
No. Review the base-rate calculation and exclusions in the offer terms.
