Sixt Car Subscription (SIXT+) is a vehicle subscription service offering rolling 30-day periods that combine insurance, maintenance and other vehicle costs into one monthly price. The minimum term is 30 days and the service is billed in 30-day periods. The contract automatically extends by 30 days if you do not return the vehicle at the end of a billing period.
Monthly rates commonly include vehicle road tax, maintenance and wear, tyre services, liability insurance and basic comprehensive insurance with an excess. Fuel or EV charging is not included. A one-off sign-up fee of £249 applies and a short-term availability charge of £549 per month may apply on some offers.

Rule - If you relocate outside the UK and cannot return to the contract branch, you must contact SIXT to arrange a return. SIXT requires the vehicle to be returned to the CONTRACT BRANCH used at pickup. If you return it to a different station, one-way fees apply.
Required proof - Proof of new address (utility bill or tenancy agreement) and written confirmation of return arrangements.
Rule - If SIXT increases the contractually agreed monthly price, check the contract terms and the official terms. Under the Consumer Rights Act 2015, an unfair contractual term may be not binding. You can raise a dispute if a price increase breaches the contractual terms or is an unfair term.
Required proof - Copy of the contract, notice of price increase from SIXT and a written complaint to SIXT.
Rule - In the event of the subscriber's death, next of kin or the estate must contact SIXT and provide documentation. The contract termination and any outstanding charges will be handled in accordance with the subscription terms and estate rules.
Required proof - Death certificate and proof of executor or next of kin authority.
Rule - The Consumer Rights Act 2015 requires the service and provided goods to be of satisfactory quality, fit for purpose and as described. If the vehicle has a persistent defect that SIXT cannot fix with reasonable care and skill, you may be entitled to termination or remedy.
Required proof - Inspection reports, repair invoices, correspondence with SIXT and photos. Reference: Consumer Rights Act 2015.
Rule - The minimum term is 30 days. You may terminate at the end of the first or second 30-day term by returning the vehicle to a SIXT branch, as returning the vehicle is deemed ordinary termination. After the third consecutive 30-day term the contract automatically terminates.
Required proof - Return receipt from the SIXT Contract Branch. Reference: SIXT vehicle return policy.
Rule - Consumer Contracts Regulations 2013 normally grant a 14-day cooling-off period for distance contracts, but SIXT states there is no right of withdrawal for contracts concluded online that are treated as bookings made by distance communication. Check the specific booking terms when you signed up.
Required proof - Copy of the online booking confirmation and the terms shown at the time of contract. Reference: Consumer Contracts Regulations 2013.
What to ask - Request a retention offer such as a temporary rate reduction, a lower excess, or a different vehicle category. SIXT does not publish standard retention offers publicly, so you must request options directly via the app, your branch or customer service. If SIXT offers a discount, get the new terms in writing and confirm the duration.
How to ask - Use the SIXT app or phone the contract branch, reference your subscription ID, state your desired monthly target and ask for written confirmation of any new offer.
Example using real prices from Sixt and competitors.
Sixt entry-level plan: from £499 per month. Yearly cost: £499 x 12 = £5,988 per year.
Competitor cheapest real alternative - Cocoon Vehicles: £299 per month. Yearly cost: £299 x 12 = £3,588 per year.
Annual saving if you move from Sixt entry-level to Cocoon: £5,988 - £3,588 = £2,400 per year.
Other comparisons:
Key UK laws and regulator - Consumer Rights Act 2015 and the Competition and Markets Authority (CMA) oversee fairness in contract terms and auto-renewals. The Consumer Contracts Regulations 2013 set rules for cooling-off rights for distance contracts.
Step 1 - Complain to SIXT in writing, citing the exact clause or defect and demand a remedy. Step 2 - If SIXT does not resolve the issue, contact Citizens Advice for guidance and mediation. Step 3 - Use Section 75 or a chargeback via your card issuer for qualifying card payments. Step 4 - If applicable, escalate to an ombudsman or the CMA for unfair contract terms. References: Consumer Rights Act 2015; Consumer Contracts Regulations 2013; CMA guidance on auto-renewals.
When you hand back the vehicle the branch will perform an inspection. If the vehicle is not clean or has damage beyond fair wear and tear, SIXT may charge for cleaning, repairs or missing items. Keep the signed return receipt and photos taken at handover.
SIXT bills in 30-day periods and charges are for full billing periods. Early return does not lead to a proportional refund: the contractually agreed monthly rate is always calculated for a full 30-day period in advance. Ensure you get a final invoice and reconcile any deposit reservations.
After termination request final statements and ask SIXT to confirm deletion or retention of your personal data under data protection rules. Keep any receipts for future disputes.
