Challenge a Garage or Mechanic Bill
Step-by-step guide · 15 min read
What you'll need
- All receipts, invoices, and quotes from the garage
- Photos/videos of your car's condition
- Text messages and emails with the garage
- An independent mechanic's written assessment
- A timeline of dates (drop-off, collection, problems)
Document everything immediately
Start documenting NOW. The more evidence you have, the stronger your case. Photos, dates, and written records win disputes.
Take photos and videos of your car's condition — before, during collection, and after any problems appear. Save everything:
- All receipts, invoices, and written quotes
- Text messages and emails with the garage
- Date you dropped the car off
- Date they said it would be ready
- Date you actually collected it
- Date problems appeared after collection
Get an independent assessment
This is your strongest piece of evidence. Do this before paying any more money.
Take the car to a different mechanic and ask for a written assessment covering:
- What work was actually done
- Whether it was done correctly
- What damage (if any) was caused by the original garage
- An estimate for fixing the problems
Get this in writing, on headed paper, with the mechanic's details. This becomes your expert evidence.
Know your rights
Under the Consumer Rights Act 2022, services must be:
- Performed with reasonable care and skill
- Completed within a reasonable time
- Charged at the agreed or reasonable price
If the garage made your car worse than before, that's a clear breach of the Act. You brought it in for a fix — they made it worse. That is not "reasonable care and skill."
Understand quotes vs estimates
This distinction matters:
- A written quote is legally binding — they cannot charge more than the quoted price
- A verbal estimate can change, but must stay reasonable
- If no price was discussed, you only need to pay a "reasonable" price for the work actually done
If you were quoted €500 and they're now charging €2,000, that's a breach. If they gave a verbal estimate, check what a reasonable price would be for that work — ask your independent mechanic.
You don't have to pay for poor work
You are NOT obliged to pay for work that made things worse.
If the repair wasn't done properly or caused further damage, you can:
- Refuse to pay for the botched work
- Demand they fix the damage at no extra cost
- Claim compensation for the damage they caused
Your independent assessment is the proof. If it shows the work was done incorrectly or caused damage, you have a strong case.
Challenge unauthorised extra work
If the garage did work beyond what you agreed to, you don't have to pay for it. The rules are clear:
- They must get your consent before doing additional work
- "We found more problems" does not entitle them to just do the work and bill you
- They should have called you, explained the issue, given you a price, and waited for your go-ahead
If they did €3,000 of extra work without your approval, you can refuse to pay for it. Tell them you never authorised the work.
Send a formal written complaint
Write to the garage owner or manager. Your letter should include:
- The original agreed work and price
- What went wrong — timeline of events
- The independent assessment findings
- What you want: refund, free repair, compensation, or a combination
- A 14-day deadline to respond
Send by registered post so you have proof of delivery. Keep a copy of everything.
Check if they're SIMI members
If the garage is a member of the Society of the Irish Motor Industry (SIMI), file a complaint with SIMI directly.
- SIMI has a dispute resolution process for complaints against member garages
- Check membership at simi.ie
- SIMI members are expected to follow a code of practice
Even if the garage isn't a SIMI member, it's worth checking — it gives you an extra avenue if they are.
Contact the CCPC
Report the garage to the Competition and Consumer Protection Commission (CCPC).
- The CCPC records complaints and can investigate patterns of misconduct
- They can advise you on your consumer rights
- If multiple consumers report the same garage, it strengthens the case for investigation
Contact them at ccpc.ie or call 01 402 5555.
Small Claims Court or civil court
If the garage won't resolve it, take legal action:
- Up to €2,000: Small Claims Court — only €25 filing fee, no solicitor needed
- €2,000 to €15,000: District Court
- Over €15,000: Circuit Court
For a dispute like €5,000, you'll need the District Court. Consider getting legal advice — many solicitors offer a free initial consultation. Your independent assessment and written complaint are your key evidence.
Don't let them hold your car hostage
A garage can hold your car (called a "lien") — but only for charges you legitimately owe.
Know the limits:
- A lien only applies to legitimate, authorised charges
- If the work was botched or unauthorised, you can argue the lien doesn't apply to the disputed amount
- Offer to pay the undisputed portion (if any) and demand release of the vehicle
- If they refuse, get legal advice immediately — a solicitor's letter often resolves this fast
Do not pay the full disputed amount just to get your car back. Once you pay, it's much harder to recover the money.
