Finding a garage you can actually trust is harder than it should be. More than half of UK drivers either suspect or aren't sure whether they've been overcharged in the last five years. Here's how to spot the good ones before you hand over your keys.
Let's be honest about the elephant in the room. A lot of people walk into our workshop in Coventry having been stung somewhere else, and they've every right to be wary. A 2026 investigation by Carly found that 52% of UK drivers either suspect or aren't sure whether they've been overcharged in the past five years, and that the same simple sensor fault was quoted anywhere from £110 to £672 depending on the garage. Same fault. Same part. Wildly different bill.
The good news? You don't need to be a mechanic to tell a straight garage from a dodgy one. You just need to know what to ask and what to look for. Here are the seven questions I'd ask if it were my car.
1. "Can I get that in writing, with parts, labour and VAT?"
This is the big one. A trustworthy garage will happily give you an itemised quote before they touch the car — parts, labour and VAT all broken out so there are no surprises at collection. Which? recommends always asking for a fixed quote that includes all three. If a garage is cagey about putting numbers on paper, that tells you something.
2. "Can you show me the fault?"
Any decent mechanic will walk you out to the car and show you the worn pad, the split boot, the leaking shock. We do it every day — Adam calls it "letting the car do the talking." If someone insists a part needs replacing but can't or won't show you why, be cautious.
Why this matters: A real customer came to us after another local garage quoted £1,100 plus VAT to replace the calipers, discs and pads on a 13-year-old Kia. We checked — the calipers were perfectly fine. We did the discs and pads for nearly £1,000 less. The only difference was an honest look before quoting.
3. "What are your reviews like — and how do you handle complaints?"
Genuine reviews are gold. Look for volume and consistency, not just a single glowing line. Read the way a garage replies to feedback, too. We're proud of our 5.0 rating across 105 Google reviews, and the words that come up again and again — honest, fair, no pressure — matter more to us than the number.
4. "Are you happy to use OE-spec parts and stamp my service book?"
A good independent uses original-equipment-quality parts and will stamp your service history just like a dealer. That keeps your warranty intact (more on that below) and protects your resale value. If a quote seems suspiciously cheap, ask what parts they're fitting — sometimes the difference is bargain-bin components that won't last.
5. "What happens if you find extra work once you're in there?"
Sometimes a job uncovers something else — that's just cars. The question is what the garage does about it. The right answer is: they stop, call you, explain it, and let you decide. The wrong answer is a surprise line on the invoice you never agreed to. Always agree how unexpected discoveries get handled before work starts.
6. "Is this a must-fix, or can it wait?"
This single question separates honest garages from the rest. A trustworthy mechanic will happily tell you what's safety-critical and needs doing now, versus what can sensibly wait a few months. We do this on every MOT and service. Nobody should be pressured into spending money they don't need to spend today.
7. "What's covered if something goes wrong with the repair?"
Ask about the guarantee on parts and labour. And know your rights: under the Consumer Rights Act 2015, any garage has a legal obligation to carry out work with reasonable care and skill. If they don't, they have to put it right or refund you. A confident garage won't flinch at that question.
The red flags, in one list
If you spot several of these, walk away: no written quote, won't show you the fault, vague about parts, pressure to decide on the spot, prices that change at collection, or work recommended without a clear reason. As the old garage saying goes — if a quote sounds too good to be true, it usually is, and so does one that sounds frighteningly expensive.
