Postclic

Cancel a car rental or subscription confidently with Postclic. Whether you need to exit a short-term hire, a long-term subscription like Sixt Car Subscription, or an occasional Zipcar booking, our two ready-to-use cancellation letters are drafted to reflect UK consumer law and give you clear, provable notice.

Common reasons for cancellation

Unmet service standards or misrepresentation

Consumers frequently cancel when the vehicle or service falls short of what was promised - for example, a different vehicle category than booked, inadequate maintenance, or undisclosed restrictions. Under the Consumer Rights Act 2015, services must be performed with reasonable care and skill; a failure here can justify termination and a refund claim.

Change of circumstances or travel plan

Personal or business plans change. Where bookings are made at a distance (online or by phone), the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 can give a 14-day right to cancel certain service contracts. Subscription models - such as those offered by Sixt Car Subscription, Enterprise subscription products or other rolling hire services - may have contractual notice periods; our letters help you invoke the correct clause.

Unfair or unilateral contract changes

Suppliers such as Hertz, Avis, or Zipcar sometimes amend terms mid-contract or impose additional charges. The Consumer Rights Act and the Unfair Terms legislation protect consumers against onerous, surprising or one-sided terms. Our guidance identifies which provisions you can challenge and how to cite them in a cancellation notice.

Your UK consumer rights

The primary protections are the Consumer Rights Act 2015 (quality, performance, and unfair terms) and the Consumer Contracts Regulations 2013 (information and cancellation rights for distance/off-premises contracts). For subscription-style rental, check the contract for statutory cancellation rights, required notice periods and any cooling-off provisions. When the supplier breaches an express term, you may be entitled to terminate, seek a price reduction or a refund; our letters reference the relevant statutes and contractual fixes.
