Manage Sixt Car Subscription

How to cancel your sixt car subscription and avoid costly notice periods

About sixt car subscription

Sixt car subscription offers you a flexible alternative to traditional car ownership and long-term leasing across the United Kingdom. Instead of committing to a finance agreement or worrying about depreciation, you drive a brand-new vehicle on a rolling monthly basis. The service bundles comprehensive insurance, road tax, maintenance, and breakdown cover into a single monthly payment-making it straightforward to budget for your transport needs.

The appeal lies in its flexibility. You receive a nearly-new car from Sixt's fleet, typically with fewer than 10,000 miles on the clock and the latest safety features built in. This makes the service particularly attractive if you're relocating for work, waiting for a company car to arrive, or testing a particular model before committing to purchase. Unlike traditional car rental, you're not swapping vehicles every few days; you get a dedicated car that's genuinely yours for the subscription period.

However, flexibility has limits. Most subscribers don't realise they must provide formal notice to cancel their agreement-and missing the deadline can lock you into additional monthly charges. This is precisely where Stopee steps in. Understanding your cancellation rights and the proper procedure before you sign up is essential, because many people only discover the notice requirements when they're ready to leave.

What makes sixt different from traditional car hire

Traditional car hire companies charge daily or weekly rates and give you a different vehicle each time. Sixt's subscription model works differently: you have one dedicated vehicle, personalisation options, and predictable monthly costs. Insurance excess, road tax, and servicing are all included, so you're not hit with surprise bills.

The catch is commitment. Your subscription doesn't end automatically when you want it to; you must actively cancel with proper notice, typically 30 days in advance. Many subscribers assume they can simply stop using the car, only to discover Sixt continues charging them. Knowing how to cancel correctly-and on time-saves you hundreds of pounds.

Who typically uses sixt subscriptions

Sixt subscriptions suit professionals on temporary assignments, families needing an extra vehicle for a season, or people who want to trial an expensive car model without the financial risk. The service also appeals to those who can't access traditional car finance or who want to avoid depreciation entirely.

Pricing, plans and what's included

Sixt's pricing structure varies by vehicle category and your mileage allowance, with transparent monthly costs that reflect the car's value and running expenses.

Vehicle categories and typical monthly costs

The subscription tiers accommodate different budgets and lifestyle needs, from economical city runabouts to executive saloons.

What's included in every subscription package

Sixt includes comprehensive insurance with an excess (typically around £1,000, varying by vehicle), full road tax coverage, regular servicing and maintenance, and 24/7 breakdown cover. You receive a nearly-new vehicle with low mileage-usually under 10,000 miles when you collect it. Standard mileage allowance is 1,000 miles per month; excess mileage costs between 10p and 25p per mile depending on your vehicle category.

The key benefit is peace of mind. You're not arranging multiple policies or paying for unexpected repairs; everything is managed by Sixt, and costs are predictable month to month.

Initial costs and setup fees

Most Sixt subscriptions require an initial deposit, typically one month's rental fee, which you'll recover when you cancel (provided the car is undamaged and you've paid all invoices). Some promotions waive this deposit, so always check your terms. First payment covers your first month's subscription, setup fees, and any delivery charges if you request home collection.

Why cancel your sixt subscription

Common reasons for cancellation include relocation abroad, purchasing your own vehicle, budget constraints, or simply needing temporary transport that's no longer required. Whatever your reason, you have the right to cancel under the Consumer Rights Act 2015, provided you follow the proper notice period.

Financial impact of cancelling early

If you cancel before your subscription term ends, you may face charges. Most Sixt agreements operate on a rolling 30-day basis, meaning you can cancel without penalty if you provide 30 days' written notice. Fail to give notice, and Sixt will charge you for an additional month. That's an avoidable cost of £450 to £1,500+ depending on your vehicle-which is precisely why understanding the cancellation procedure matters.

When you should cancel versus when you should keep going

How to cancel your sixt subscription

Sixt allows cancellation through three methods: online via the Sixt+ app or website, telephone contact with customer service, or formal written notice by post. Each method has specific requirements and timelines-getting them right ensures your cancellation is processed without dispute.

Cancelling online through the sixt+ app or website

Online cancellation is the fastest and most documented method, because you'll receive written confirmation immediately.

1. Log into your Sixt+ account using your email address and password
   • If you've forgotten your password, use the 'Forgot password?' link to reset it
   • Access the app or visit www.sixt.co.uk
2. Navigate to 'My subscriptions' or 'Active agreements' in your account dashboard
   • This section displays all current vehicles and subscription terms
   • You'll see your next payment date and notice period requirements
3. Select the subscription you wish to cancel
   • Verify the vehicle registration number and monthly cost match your records
   • Take a screenshot for your own records
4. Click 'Cancel subscription' or 'End agreement' (wording varies by the app version)
   • The system will ask you to confirm your cancellation and provide a reason (optional)
   • This data helps Sixt improve, but you're not required to answer
5. Enter your notice period end date
   • The system will calculate this automatically based on your agreement terms
   • Typically this is 30 days from the date you submit the request
   • Warning: If you submit on 15th June, your cancellation date is 15th July-not sooner
6. Confirm the cancellation and save your confirmation email or screenshot
   • This is your proof of cancellation; keep it for at least 12 months
   • Sixt may contact you to arrange vehicle return logistics

Pro tip: Cancel on the first working day after you receive your monthly invoice. This ensures you're not charged twice and the system clearly logs your request before the next billing cycle begins.

Cancelling by telephone

Telephone cancellation works if you prefer speaking to a representative directly, but you must follow up with written confirmation to create an audit trail.

1. Call Sixt customer service on the number listed in your subscription documents or on the Sixt website
   • Customer service hours are typically 08:00-20:00 Monday to Friday, 09:00-18:00 Saturday
   • Have your subscription number and vehicle registration ready
2. Confirm your identity and account details with the adviser
   • They'll ask for your postcode, registration number, or policy reference
   • This protects your account from unauthorised changes
3. Clearly state your intention to cancel with 30 days' notice
   • Say: "I'd like to cancel my subscription with 30 days' formal notice, effective [specific date 30 days from today]"
   • Do not say "I might cancel" or "I'll probably end it soon"-be decisive
4. Request a confirmation number for your cancellation
   • Write this down immediately with the date and time of your call
   • The adviser should provide a reference code or ticket number
5. Ask the adviser to email you a cancellation confirmation
   • Request their full name and email address
   • This creates a written record beyond your call log
6. Follow up with a written email to Sixt reiterating your cancellation request
   • Include the confirmation number from your phone call
   • Keep a copy in your own email inbox or printed file

Warning: Telephone cancellations are valid, but advisers occasionally fail to log them correctly. Always request written confirmation and follow up with email. Without this, Sixt may claim they never received your request and charge you for an extra month.

Cancelling by formal written notice (post)

Written notice by post is the slowest method but creates ironclad proof of your cancellation request. Use this if online or telephone options aren't working or if you want maximum legal protection.

1. Obtain Sixt's registered office address from your subscription agreement or the website
   • Address typically appears on your monthly invoice
   • Verify the address is current before posting
2. Write a formal letter on plain paper or headed notepaper
   • Date the letter clearly at the top
   • Use formal language: "I hereby give notice of cancellation of my Sixt car subscription…"
3. Include all required information in your letter:
   • Your full name and address
   • Your subscription number or policy reference
   • The vehicle registration number (the car's number plate)
   • Your intended cancellation date (minimum 30 days from posting date)
   • Contact telephone number and email address
4. Print and sign the letter by hand
   • Typewritten or printed signatures are less legally binding
   • Sixt may dispute digital signatures in disputes
5. Send the letter by Signed For 1st Class post or Special Delivery
   • Never use standard 2nd Class post-you need proof of delivery
   • Request a proof of posting certificate at the Post Office counter
   • Keep this certificate in a safe place for 24 months
6. Allow 5-7 working days for delivery, then wait for Sixt's written confirmation
   • Sixt should confirm receipt within 10 working days
   • If you don't hear back within 2 weeks, send a follow-up email with a copy of your proof of posting

Pro tip: Take a photo of your completed letter before posting it. Include the date and Sixt's address visible in the photo. This acts as secondary proof if a dispute arises later.

Your consumer rights under UK law

The Consumer Rights Act 2015 protects you when cancelling a subscription service. Understanding these rights gives you leverage if Sixt refuses to cancel or continues charging after you've requested termination.

Right to cancel within the cooling-off period

If you signed up to your Sixt subscription online or at a distance (not in a Sixt showroom), you have a 14-calendar-day cooling-off period from the date the contract was concluded. During this window, you can cancel without reason and without penalty. Sixt must refund your initial deposit and any charges within 14 days of your cancellation request.

Important: If you've already used the car during the cooling-off period, Sixt can charge you a reasonable fee for use, but only the actual cost of that use-not a penalty or admin fee. If you cancel within 14 days without having driven the car, you should receive a full refund.

Right to cancel after the cooling-off period

After 14 days, your subscription becomes a rolling monthly contract. You can still cancel, but you must provide the notice period specified in your agreement-typically 30 days. Sixt cannot refuse cancellation after notice is given, and they cannot charge you beyond the notice period end date.

Right to a refund of your deposit

Your initial deposit is held as security for damage, excess mileage, or unpaid invoices. When you return the car in good condition with no outstanding charges, Sixt must refund your deposit within 14-30 days. If they claim deductions for damage, they must provide itemised evidence (photographs, repair quotes) and give you the opportunity to dispute the charges. Under the Consumer Rights Act 2015, unfair contract terms-such as withholding a deposit without justification-are not binding on you.

Right to complain to the financial conduct authority

If Sixt refuses to cancel, continues billing after your notice period ends, or unreasonably withholds your deposit, you can escalate to the Financial Conduct Authority (FCA) or the Financial Ombudsman Service (FOS). Both bodies investigate consumer complaints against regulated financial services providers and can order refunds or compensation. Stopping at Stopee is one step; knowing your regulatory rights is another.

Timeline and notice period requirements

Most Sixt subscriptions operate on a rolling monthly basis with a 30-day notice period. However, some premium or corporate agreements may have different terms, so always check your specific contract.

Standard 30-day notice period

If you provide notice on 15th June, your subscription ends on 15th July. You'll be charged for your full July payment unless you cancel before the monthly cycle begins. Your final payment will be processed 3-5 business days after your cancellation date. The car must be returned within 7 days of your notice period ending; failure to return it may result in additional charges.

What happens if you miss the notice deadline

If you fail to give 30 days' notice and simply stop using the car, Sixt will continue charging you. Many subscribers discover this when they see an unexpected charge 45 days later. Each additional month costs the full subscription fee-£450 to £1,500+ depending on your vehicle. This is entirely avoidable by marking your cancellation deadline in your phone calendar on the date you subscribe.

Vehicle return and final logistics

After your notice period expires, you must return the car to Sixt in clean, undamaged condition with a full tank of fuel. Failure to return on time incurs additional daily charges, typically £25-£50 per day depending on the vehicle.

Return procedures

Sixt will contact you 5-7 days before your cancellation date to arrange return logistics. You can either drive to a Sixt location and drop off the vehicle, or arrange home collection if you're outside a major city. Return times are typically 09:00-17:00 Monday to Friday. Before returning the car, ensure the interior and exterior are clean, the fuel tank is full, and you have all original keys and documents.

A Sixt representative will conduct a damage inspection at the return location. If damage is found, they'll photograph it and provide an estimate. You'll receive an inspection report within 7 days. If you disagree with damage claims, contact Stopee or a consumer advice centre immediately-you have the right to challenge unfair deductions.

Deposit refund timeline

Your deposit refund is processed 14-30 days after vehicle return, assuming no damage claims. If Sixt claims deductions, the refund timeline extends while they obtain repair quotes. You should receive an itemised breakdown explaining any deductions within 28 days of return.

Common cancellation mistakes to avoid

Cancelling a car subscription shouldn't be complicated, yet thousands of UK customers accidentally extend their contracts by weeks or months through simple oversights.

Mistake 1: submitting cancellation requests without keeping proof

If you cancel by phone and don't request written confirmation, Sixt may claim they never received your request. Always document your cancellation with email confirmations, reference numbers, or screenshots. This isn't paranoia-it's standard practice when money is involved. Keep these documents for 24 months after your cancellation date.

Mistake 2: missing your notice period deadline

The notice period clock starts when your request is officially received, not when you submit it. If you phone on Tuesday morning and the adviser says "we'll process that today," confirm in writing by email immediately after the call. Don't assume they've logged it until you receive written confirmation. Missing a 30-day deadline by just one day locks you into another full month's subscription.

Mistake 3: confusing your cancellation date with your return date

Your cancellation date ends your contractual obligation and billing responsibility. Your return date is when you physically hand over the car to Sixt. These are not the same. The car must be returned within 7 days of your cancellation date, not on the cancellation date itself. Sixt charges daily storage fees if you're late.

Mistake 4: returning the car without a full tank or failing to clean it

Sixt reserves the right to charge for refuelling (typically £50-£100) and deep cleaning (£75-£150) if you return the car less than full or visibly dirty. These aren't damage claims-they're service charges you can easily avoid. Before return, fill the fuel tank and clean the interior thoroughly.

Mistake 5: accepting damage claims without evidence

When you return the car, Sixt's inspector will note any damage. If they claim a scratch, dent, or stain is chargeable, ask to see photographs taken during your pickup inspection. Sixt must prove the damage didn't exist when you collected the car. If they can't provide before-and-after evidence, the deduction is unfair under consumer law and you can dispute it via the Financial Ombudsman Service.

Mistake 6: failing to provide a forwarding address for your deposit refund

Ensure Sixt has your correct mailing address on file before you return the car. If your address changes between cancellation and return, notify them immediately. Sixt cannot refund to an old address, and delays in receiving your refund cheque are your responsibility if you've moved and didn't update your details.

After your cancellation is processed

Cancelling your subscription doesn't end the moment Sixt confirms your request-several important steps follow, and staying organised protects you against disputed charges.

What happens to your billing after cancellation

Sixt will stop charging you after your notice period ends. However, if you've exceeded your mileage allowance, they'll calculate excess mileage charges and deduct them from your deposit refund. If you've received a final invoice, check it carefully against your odometer reading and the agreed mileage rate (10p-25p per mile depending on your vehicle). If the charges seem incorrect, contact Sixt within 14 days with your objection.

Receiving and checking your deposit refund

Your deposit refund should arrive 14-30 days after you return the car. When it does, verify the amount matches your original deposit. If deductions have been made, Sixt should have provided an itemised breakdown. If you disagree with the deductions, raise a formal complaint with Sixt within 8 weeks of the refund being processed. If Sixt refuses to negotiate, escalate to the Financial Ombudsman Service (www.financial-ombudsman.org.uk).

Confirming cessation of all charges

Check your bank or credit card statements for 60 days after your cancellation date to ensure Sixt has stopped charging you. If you see a payment after your notice period has ended, contact Sixt immediately to request a reversal. Most banks can recall erroneous payments within 35 days if you report them promptly. Keep your cancellation confirmation email handy to prove to your bank that you've cancelled.

What to do if sixt continues charging after cancellation

If Sixt charges you after your notice period ends, this breaches the Consumer Rights Act 2015. First, contact Sixt in writing (email and post) with your cancellation confirmation reference and request an immediate reversal of the unauthorised charge. Allow 7 working days for their response. If they refuse, file a complaint with the Financial Ombudsman Service, which can order them to refund you plus compensation for inconvenience (typically £50-£300).

Refund eligibility and timelines

Your refund eligibility depends on whether you cancel within the 14-day cooling-off period or after it, and whether any deductions apply.

Comparison: cancel versus downgrade

Before you cancel entirely, consider whether downgrading to a cheaper vehicle or shorter mileage allowance better suits your situation. Downgrades avoid cancellation fees and let you retain a Sixt vehicle if you still need occasional access.

Stopee recommends contacting Sixt before you formally cancel if you're uncertain about your long-term transport needs. Sometimes a cost-saving adjustment is simpler than the full cancellation process.

Customer reviews and satisfaction ratings

Sixt car subscription holds a 4.5 out of 5 star rating across consumer review platforms, with particular praise for vehicle quality, insurance coverage, and delivery convenience. However, recurring complaints centre on cancellation procedures, deposit refund delays, and unexpected damage claims at return.

Positive feedback highlights the simplicity of including insurance and road tax, the quality of nearly-new vehicles, and friendly customer service. Negative reviews frequently mention that customers were unaware of the 30-day notice requirement and were charged for additional months unexpectedly. This reinforces how important it is to understand cancellation terms before you sign up.

If you've had a poor experience cancelling Sixt, Stopee has helped thousands of consumers pursue refunds and challenge unfair charges. Documenting your cancellation request and any subsequent disputes gives you evidence to support a complaint with the Financial Ombudsman Service.

Where to send your written cancellation notice

If you choose to cancel by formal written notice, send your letter to Sixt's registered office address. Verify this address is current on your latest invoice or the Sixt website before posting, as office addresses occasionally change.

Sixt car subscription cancellation address:

Sixt Ltd
Registered Office
[Check your subscription agreement or www.sixt.co.uk for the current postal address]

Include your subscription number, vehicle registration, and full name and address in your letter. Send by Signed For 1st Class post or Special Delivery and retain your proof of posting certificate for 24 months.

Final checklist before you cancel

Use this checklist to ensure you've covered every step and protected yourself against post-cancellation disputes.

• Check your subscription agreement for the exact notice period (usually 30 days)
• Calculate your cancellation deadline by adding the notice period to today's date
• Choose your cancellation method: online (fastest), telephone (followed by email), or written notice (slowest but safest)
• Submit your cancellation request and immediately save confirmation in email, screenshot, or printed form
• If by phone, request a confirmation number and ask for written confirmation to be emailed to you
• If by post, use Signed For 1st Class post and keep your proof of posting certificate
• Mark your cancellation deadline on your phone calendar to avoid accidental late renewal
• Ensure Sixt has your current mailing address for your deposit refund
• Confirm the return date and location with Sixt 7-10 days before your cancellation date ends
• Clean the car inside and out and fill the fuel tank before return
• Document the vehicle's condition (photographs of interior and exterior before return)
• Request a written damage inspection report at the return location
• Check your bank statements weekly for 60 days after your cancellation date to ensure charges have stopped
• When your deposit refund arrives, verify the amount and itemised deductions against your documentation
• If you disagree with damage deductions or continued charges, contact Stopee or the Financial Ombudsman Service within 8 weeks
