Which? has been championing consumer rights since 1957. It's one of the most recognised names in UK consumer advocacy, and their free rejection letter template is often the first thing people download when they discover their car is faulty.
But is a single template enough to get your rejection through?
Why People Consider Which?
Which? carries serious weight. Nearly seven decades of consumer advocacy means dealers take notice when they see a Which?-style letter.
Their website offers a free downloadable template for rejecting a faulty car — a Word document you can fill in with your details. They also publish thorough guides on consumer rights and, for paying members at £10.99 per month, provide access to a legal helpline where you can speak to an adviser.
What Which? Does Well
The free template letter is a perfectly reasonable starting point. It covers the basics — identifying the fault, referencing the Consumer Rights Act 2015, and requesting a rejection. Their consumer rights guides are detailed and well-researched, drawing on decades of expertise.
If you're a Which? member, the legal helpline adds a layer of personal advice that can be valuable, especially if your situation is complex.
Which?'s broader reputation also helps. A letter that follows their template format signals to the dealer that you've done your homework. The brand carries credibility, and that's worth something in a dispute.
Where It Falls Short for Car Rejection
The fundamental limitation is that Which? gives you a starting point but not a process. Their free offering is a single template — one letter, one stage.
Rejecting a faulty car rarely ends with the first letter. Dealers stall, make excuses, offer repairs instead of refunds, or simply ignore you. When that happens, you need a follow-up strategy.
Which?'s template doesn't cover what comes next. No chase letters for when the dealer goes silent. No finance company letters for Section 75 claims. No responses to the classic dealer excuses — "we'll repair it under warranty," "the fault is wear and tear," "you've driven too many miles."
There's no deadline tracking to ensure you stay within the 30-day window. And no evidence storage for the photos, videos, and documents that strengthen your case.
The legal helpline helps fill some of these gaps, but it requires an ongoing £10.99 monthly membership. Over a car rejection that might take two to four months, that adds up — and you're paying for broad consumer membership, not a dedicated car rejection service.
When FaultyCar.co.uk Is the Better Choice
FaultyCar.co.uk picks up exactly where Which?'s template leaves off.
Instead of one generic letter, you get a full set of CRA-specific templates covering every stage: initial rejection, dealer chase, finance company notification, Section 75 claims, and escalation. Each letter is personalised to your situation rather than a fill-in-the-blanks document.
Deadline tracking with email reminders ensures you don't miss the critical 30-day window or let a dealer run out the clock by ignoring you. Evidence storage keeps everything organised — fault photos, diagnostic reports, MOT history, repair invoices — so it's all ready if you need to escalate.
And when the dealer hits you with a scripted excuse, you get a legally grounded response ready to go.
All of this comes for a one-off £69 fee. No monthly subscription, no ongoing costs. You send the letters yourself and you keep 100% of any refund you receive.
Our Honest Take
Which? is a genuinely excellent organisation and their free template is a decent first step. If your situation is straightforward — the dealer is cooperative and responds to your first letter — you might not need anything more.
But most faulty car rejections aren't that simple. Dealers push back, deadlines loom, and you need more than one letter to get the job done.
Our platform gives you the complete toolkit for £69 — less than two months of Which? membership and far more targeted to your specific problem. Read their guides to understand the landscape, then use our letters and tracking to execute your rejection step by step.
The verdict
Which?'s template is a solid free starting point. FaultyCar.co.uk provides the full toolkit — personalised letters for every stage, deadline tracking, and evidence management — for a one-off £69.
Which? is best for: People who want a single free template to start their rejection, or existing Which? members who want access to the legal helpline
