How to complain to a garage in writing

The same fault is back — do these three things first

You collected the car. The same noise, the same light, or the same fault is back. The garage is talking about more work, or another bill, and you think that is wrong.

Do not try to win the argument at the counter. The phone call is the opening move; the letter or email is the record. Write while the car, the invoice and the symptoms are still fresh. This opening is a situation, not a finding about your contract, and it does not name a going rate.

Checklist

• Write down the one problem, the outcome you want, and a clear reply date.
• Pick the complaint that actually fits: the work was done badly, the garage did not do what it told you it would do, the job took too long, or the bill is higher than what was agreed.
• Keep the invoice, the estimate or quote, and a copy of exactly what you send.

Why the first complaint should be in writing

For civil claims in England and Wales, the Practice Direction on Pre-Action Conduct and Protocols applies to disputes where no approved pre-action protocol applies, and says that before proceedings are commenced the court will expect the parties to have exchanged sufficient information to understand each other's position, make decisions about how to proceed, try to settle the issues without proceedings and consider a form of alternative dispute resolution.

For civil claims in England and Wales, the same Practice Direction says litigation should be a last resort, and that a party's silence in response to an invitation to participate in alternative dispute resolution, or a refusal to participate, might be considered unreasonable by the court and could lead to an order to pay additional court costs. Sources: ^[5]

If an England or Wales dispute later reaches litigation, the court will expect the parties to have complied with the Practice Direction, will take non-compliance into account when giving directions and when making orders for costs, and treats not providing sufficient information or not acting within a reasonable period as possible failures of compliance.

On its default England car-repair page, Citizens Advice says that if the garage does not agree up front to make things right, you may want to write or email the garage so that you have a record of the problem and of your communication with them. Sources: ^[7]

Litigation should be a last resort.

What to do

• Treat the phone call as the opening move and the letter or email as the record; a conversation nobody wrote down is hard to rely on later.
• Send the written complaint even if the garage sounded co-operative on the phone, because a dated document costs nothing and fixes the timeline.
• Write while the car, the invoice and the symptoms are still fresh, rather than waiting to see whether the problem returns.

Say which part of the deal was broken

Section 54 of the Consumer Rights Act 2015 defines a service conforming to the contract as the service being performed in accordance with section 49, or conforming to a term that section 50 requires to be treated as included in the contract and that relates to performance of the service. Sources: ^[4]

Where the service does not conform to the contract, section 54(3) gives the consumer the right to require repeat performance under section 55 and the right to a price reduction under section 56. Sources: ^[4]

Where the trader is in breach of what the contract requires under section 52 about performance within a reasonable time, section 54(5) gives the consumer the right to a price reduction, and does not list repeat performance for that breach. Sources: ^[4]

Section 50 treats anything said or written to the consumer by or on behalf of the trader about the trader or the service as a term of the contract, if the consumer took it into account when deciding to enter the contract or when making a decision about the service afterwards. Sources: ^[2]

Section 51 applies to a contract to supply a service if: (a) the consumer has not paid a price or other consideration for the service; (b) the contract does not expressly fix a price or other consideration and does not say how it is to be fixed; and (c) anything treated under section 50 as included in the contract does not fix a price or other consideration either. A complaint about the size of the bill therefore needs to make clear whether anything has been paid and whether a price was agreed, quoted or only estimated. Sources: ^[3]

On its default England car-repair page, Citizens Advice says that where you agreed an amount or received a quote before the work was done you have entered into a contract with the garage and will have to pay the full bill, whereas where the garage gave only an estimate it can charge more within reason. Sources: ^[7]

On its default England poor-service page, Citizens Advice suggests telling the garage that the Consumer Rights Act 2015 says services must be provided with reasonable care and skill, that in your opinion reasonable care and skill was not used, and that you want the problem fixed or a price reduction. Sources: ^{[1] [8]}

If the service does not conform to the contract, the consumer's rights (and the provisions about them and when they are available) are— (a) the right to require repeat performance (see section 55); (b) the right to a price reduction (see section 56).

If the trader is in breach of what the contract requires under section 52 (performance within a reasonable time), the consumer has the right to a price reduction (see section 56 for provisions about that right and when it is available).

What to do

• Pick the complaint that actually fits: the work was done badly, the garage did not do what it told you it would do, the job took too long, or the bill is higher than what was agreed. They lead to different asks.
• For work done badly, ask for the job to be put right and say so in those words, rather than opening with a demand for money.
• For a job that overran, remember the Act routes that breach to a price reduction rather than to doing the work again, so ask for the reduction and explain how you arrived at the figure.
• For a disputed bill, quote back what you were told when you booked, and attach the estimate, quote or booking message you relied on.
• Do not stack every possible complaint into one letter; the strongest letter is the one the garage can act on.

What an effective letter contains

For civil claims in England and Wales, the Practice Direction says the steps before issuing a claim will usually include the claimant writing to the defendant with concise details of the claim, including the basis on which the claim is made, a summary of the facts, what the claimant wants from the defendant, and if money, how the amount is calculated.

For civil claims in England and Wales, it also expects the parties to disclose key documents relevant to the issues in dispute. Sources: ^[5]

The default England version of the Citizens Advice template letter for a poor standard of service sets out the date the work was agreed, what was agreed, any agreed completion date and cost, a numbered list of the problems, the outcome wanted, and a request that the trader responds or completes the work within a stated period. Sources: ^[9]

On that default England page, Citizens Advice says the template letter can be sent by post or copied into an email, and points readers to its car-repair advice before using it. Sources: ^[9]

What to do

• Identify the vehicle unambiguously: registration, make and model, and the job or invoice number the garage used.
• Give the dates that matter: when you booked it in, when you were told it would be ready, when you collected it and when the problem appeared.
• Describe the symptoms in the same plain terms you used at the counter, including any warning light and whether it is on constantly or intermittently.
• State what you paid, when and how, and attach the invoice and the estimate or quote.
• State the one outcome you want — the work done again, or a specific reduction — and, if it is money, show the arithmetic.
• Set a clear date for a reply rather than saying 'as soon as possible'.
• Keep it factual and dated; do not assert what the garage did wrong mechanically unless you can evidence it.
• Do not treat any template as having legal force of its own; it is a way of setting out your position clearly.

The response date, copies and how you send it

For civil claims in England and Wales, the Practice Direction describes the defendant responding within a reasonable time as 14 days in a straightforward case and no more than 3 months in a very complex one. Sources: ^[5]

For civil claims in England and Wales, the Practice Direction adds that it must not be used as a tactical device to secure an unfair advantage, and that only reasonable and proportionate steps should be taken. Sources: ^[5]

On its default England car-repair page, Citizens Advice advises keeping a record and receipts of any extra money you have to pay for travel while a bill is in dispute, because you might need to prove it later. Sources: ^[7]

On its default England car-repair page, Citizens Advice advises asking the garage what it can do to help before spending extra money on hire cars or travel, and says a court is not likely to award money where the garage offered services you did not take up.

On its default England car-repair page, Citizens Advice advises that where you need the car back but dispute the amount you should pay 'under protest' and write those words clearly on the garage's copy of the repair order sheet and on any copies of receipts the garage makes. Sources: ^[7]

What to do

• For an England or Wales dispute, give a response date that is defensible rather than dramatic; two weeks is the period the Practice Direction associates with a straightforward case. Do not import that period into Scotland or Northern Ireland.
• Keep a copy of exactly what you sent, not a summary of it.
• Email gives you a timestamp and a sent copy for free; if you post it, keep proof of posting and put a copy in the same file.
• If you hand it over at the counter, ask for it to be signed and dated as received, and keep the signed copy.
• Keep the whole file together: booking, estimate or quote, invoice, payment record, your letter, and anything the garage sends back.
• Note the date the deadline expires in your calendar, because the later routes all ask when you complained and what happened next.

If the garage refuses or ignores you

For civil claims in England and Wales, the Practice Direction says that where a dispute has not been resolved after the parties have followed it, they should review their positions and consider the papers and the evidence to see whether proceedings can be avoided, and at least seek to narrow the issues in dispute.

Section 54(6) and (7) say the rights to repeat performance and a price reduction do not prevent the consumer seeking other remedies, including claiming damages, but not so as to recover twice for the same loss. Sources: ^[4]

GOV.UK says those services can refer a complaint to local Trading Standards officers, who may then investigate, and can share complaint information nationally with enforcement authorities. Sources: ^[6]

On its default England car-repair page, Citizens Advice says that if you ask whether the garage belongs to an alternative dispute resolution scheme and it does not respond, is not a member, or will not use the scheme, you should keep a record of when you asked because the page says you will need it if the dispute reaches court. This is reported as England practical advice, not as court procedure for another nation. Sources: ^[7]

What to do

• Do not send a second, angrier letter. Send one short chaser that refers to the first letter by date and repeats the same ask.
• Ask in writing whether the garage belongs to a trade association or an alternative dispute resolution scheme, and keep the reply or the silence.
• Only then look at alternative dispute resolution, and after that at a court claim in your own nation; both start from the written complaint you have already made.
• Get free advice from the service for your nation before you spend money on an independent inspection or another garage.

No letter, template or wording guarantees a repair, a refund or any other outcome.

Do not drive a vehicle you have been told is unsafe in order to return it to the garage or to gather evidence; arrange recovery where the reviewed safety conclusion requires it.
