Free car repair garage dispute letter template

Use this letter to record what a garage agreed to do, what was actually done, the remaining fault and the refund or corrective work you require.

Who this letter is for

Challenge poor repairs, work you did not authorise or a bill that exceeds the agreed estimate. It is written in the formal register companies, landlords and card issuers expect, and it records the facts, the remedy sought and the deadline in a way that supports any later escalation to an ombudsman or the courts.

How to use this template

  1. 1Collect the estimate and invoice.
  2. 2Record the remaining or new fault.
  3. 3Obtain an independent report where possible.
  4. 4Choose corrective work or a price reduction.
  5. 5Set a written response deadline.

What to include before you send it

  • Keep the estimate, invoice, diagnostic report and all messages with the garage.
  • Obtain an independent report before another garage changes the disputed work where possible.
  • State whether you want repeat performance, a price reduction or reimbursement of corrective work.

The rights you are relying on

The Consumer Rights Act 2015 requires UK services to be performed with reasonable care and skill; equivalent service guarantees may apply in other countries.

Re: Formal complaint about repairs to [VEHICLE], registration [REGISTRATION]

Dear Sir or Madam,

On [DATE] I authorised you to carry out [AGREED WORK] for an agreed estimate of [AMOUNT]. I collected the vehicle on [DATE] and paid [AMOUNT], invoice [NUMBER].

The service is disputed because [the original fault remains / a new fault appeared / work was carried out without authority / the final charge exceeded the estimate without consent]. The evidence is [DIAGNOSTIC REPORT / PHOTOGRAPHS / MESSAGES].

I require [the work repeated at no charge by DATE / a price reduction or refund of AMOUNT / reimbursement of AMOUNT for necessary corrective work]. Please do not carry out further chargeable work without my written approval.

Please respond within 14 days. If unresolved, I will consider the relevant motor-trade dispute scheme, card provider and small-claims route.

Yours faithfully,

[Your name]

Enclosures: estimate, invoice, report, photographs and correspondence.
