Cheapest Quote, Dearest Bill: A Driver's Guide to Reading Garage Estimates

Two garages. Same knackered wheel bearing. One quote says £420, the other says £610. Before you ring the cheaper one and book it in, take a breath. A quote is not a price until you know what is actually inside it.

At Grosvenor Garage, we see this all the time: drivers comparing the bottom line on two bits of paper when the real differences are buried in the middle. One quote might use a budget part and skip the wheel alignment. The other might include new mounting bolts, a proper road test and a two-year warranty. Same job on paper. Very different job in reality.

So here is how to compare garage estimates without getting fooled by a tidy-looking total.

Make Sure Both Quotes Describe the Same Job

Start with the scope, not the price. If one estimate says 'replace front wheel bearing' and the other says 'replace front hub assembly', those are not automatically the same thing. Ask each garage to spell out what will be removed, replaced and checked.

A fair quote should list the parts, the labour and any extra work that might be needed once the car is stripped down. If one garage has quoted for a bearing and the other has quoted for a bearing plus hub, you are comparing apples with a fruit basket. Get both quotes itemised before you decide anything.

Parts Grades: Where the Quiet Savings Live

This is the big one. 'A new part' can mean several different things. You might be offered a genuine manufacturer part, a quality equivalent from a known brand, a budget aftermarket part, or a used part from a breaker. None of those are automatically wrong. They are just not the same.

Ask for the part brand and, where possible, the part number. A cheap bearing might get you through the next 12 months. A decent one might last five years. If one quote is £150 cheaper, find out whether that saving is coming from the part, the labour, or both. Also ask what warranty comes with the part and the workmanship. A quote without a clear warranty is only half a quote.

Labour Rates and Book Times

Labour is usually the biggest chunk of any repair bill, and it is where two quotes can drift apart fast. One garage might charge £55 an hour, another £95. That does not automatically make the cheaper one better value. A sharp outfit with the right tools and experience might do the job in less time and spot related problems while they are in there.

Check whether the quote shows labour hours as well as an hourly rate. If it just says 'labour £180', ask how that was worked out. For bigger jobs, ask whether the price is fixed or whether it can rise if bolts shear or a bearing housing is corroded. A good garage will be honest about that before you authorise anything, not after.

VAT: The Comparison Trap

A surprising number of quote comparisons go wrong here. One garage quotes £500 including VAT. Another quotes £500 plus VAT. That second one is actually £600. Make sure both figures are on the same footing.

A proper estimate should state clearly whether VAT is included and show the VAT amount if the garage is VAT-registered. If you are comparing a quote from a small workshop that is not VAT-registered with one from a larger garage, the totals can look closer or further apart than they really are. Compare the final amount you will pay, not the headline number.

Watch for Vague Extras and Padding

Not every extra is a con. Some are genuine costs. But you should know what you are paying for. Look out for lines like 'shop supplies', 'environmental charge', 'consumables', 'diagnostic fee' or 'admin fee'. Some garages use these as legitimate small charges; others use them to fatten the bill without it looking obvious.

Ask what each one covers. If a diagnostic fee is included, does it come off the repair bill if you go ahead? If there is a disposal charge, what is being disposed of? If a courtesy car is listed, do you actually need it? None of these are deal-breakers on their own, but a quote full of fuzzy extras is a quote that needs a few questions.

What a Good Quote Looks Like

A decent estimate does not need to be a work of art. It just needs to be clear. It should show the vehicle, the fault or job, the parts being used, the labour rate and hours, any extra charges, VAT, the total, and how long the work should take. It should also say what happens if the garage finds something else once the car is in bits.

That last point matters. You want to know that nobody is going to add £200 of work without ringing you first. A good garage will ask before doing extra work. A vague garage will tell you after the fact and hand you a bigger bill.

Questions to Ask Before You Say Yes

Before you authorise any repair, ask: is this price fixed or estimated? What brand of parts are you using? What warranty do I get? Will you call me before doing any extra work? Can I see the old parts? And what happens if the job takes longer than expected?

Those questions are not awkward. They are normal. A garage that gets shirty about them is telling you something useful.

The cheapest quote is not always the dearest bill in disguise, and the priciest quote is not always the best one. But the number at the bottom only means something when you know what sits behind it. Compare the job, the parts, the labour, the VAT and the warranty. Then choose the garage that makes the whole thing make sense.
