When your car needs repairing, you want it done right. But how do you know if the garage you've chosen is trustworthy, or if they’re likely to take you for a ride? Here are eight red flags to keep an eye out for.
1. Unclear quotes
A good garage should be able to provide a clear quote for any repair, and unless additional work is required, this should match the final price on the invoice.
If a garage refuses to give you a quote before carrying out the work, or the price on the invoice is higher than you were quoted without a reasonable explanation, it's a sign that the garage might not be trustworthy.
2. Unrealistically cheap prices
There's no way around it: some repairs are expensive because they require more labour hours. If you get a quote for a clutch replacement that says the job will cost £200 when you know the average price is usually more like £500, you should be suspicious.
Everyone likes a good deal, but if a repair is unreasonably cheap, ask yourself why. Low-quality car repairs likely won’t last and may actually be dangerous.
3. Poor communication
Any mechanic who works on your car should be happy to explain:
What the problem is
What the repair involves
How much it will cost
Approximately how long it will take
If you can’t get a straight answer, you should think twice about using that garage.
4. Unapproved extra work
Mechanics should never carry out work that you haven’t approved.
Top tip: Before a garage starts working on your car, ask for confirmation that they will contact you to get your approval if they discover any additional work is required.
5. Messy premises
A good garage should have clean, well-organised premises with a tidy reception and, ideally, a warm and comfortable waiting room. Waste products, such as used engine oil and tyres, should be disposed of safely.
If the premises of your chosen garage are cluttered, full of junk, unsafe or generally look rundown, this is a red flag.
6. High-pressure tactics
Aggressive or manipulative sales tactics should immediately set alarm bells ringing. These tactics rely on creating a sense of fear or urgency to get you to agree to a repair your car might not need.
Common examples include:
Overstating the problem - Claiming a minor issue is dangerous or will lead to catastrophic failure if not fixed immediately.
Time pressure - Saying “We have to fix it today or your car will break down on the road.”
Emotional pressure - Suggesting that not doing the repair could endanger your family or cause major inconvenience.
Some car problems can be dangerous and require an urgent repair, but you should never feel like you’re being pressured into a quick decision, and the mechanic should take the time to help you understand the issue.
7. Unprofessional staff
Garage staff should always speak to you in a professional, polite and respectful manner. Bad customer service can indicate deeper issues, such as a lack of accountability and misplaced priorities, which often go hand-in-hand with low-quality repairs.
8. Bad reviews
One of the most important things to do when choosing a garage is to check customer reviews. If most reviewers give one or two stars, it’s best to steer clear, as you’re unlikely to receive good service.
On the flip side, if a garage only has five-star reviews - and a lot of them - this could be a sign that the reviews are fake. Keep an eye out for repeated content.
9. Refusal to show old parts
A reputable garage should be willing to show you the parts they’ve replaced if you ask. For example, if they claim your brake pads were worn out, you should be able to see the old pads.
If a garage avoids this or makes excuses (“we threw them away already,” “we don’t keep them”), it could suggest the work wasn’t actually done, or the part didn’t need replacing in the first place.
Some customers even request old parts back as proof of replacement, which honest mechanics are usually fine with.
10. No paperwork or receipts
Good garages are transparent: they’ll give you a written quote before work and a proper receipt afterwards. If a garage is vague, reluctant, or only offers a handwritten scrap without detail, it’s hard to prove what you’ve paid for or to go back if there’s a problem later.
Lack of paperwork could also hint at tax evasion or that the garage is operating outside of proper regulations.
How to avoid red flags: choose a FixRated garage
Spotting red flags is useful, but the best way to protect yourself is to choose a garage that has already proven to be trustworthy. That’s where FixRated, FixMyCar’s approved garage network, comes in.
