Failed Your MOT? What Happens Next
If your car has just failed its MOT, the first thing to establish is whether any defect was recorded as “dangerous”. That single word decides whether you can drive the car away at all.
- Dangerous defect: you must not drive it. Not home, not to another garage. Driving it risks prosecution and invalidates your insurance.
- Major defect only, and your old certificate has not yet expired: you may generally still drive until it expires, though you are responsible for the car being roadworthy.
- Major defect and your certificate has expired: you may only drive to a pre-arranged repair appointment or a pre-booked retest.
Check the top of your VT30 refusal notice. It states the category against each item.
What the paperwork actually says
A failure produces a VT30, the refusal of an MOT test certificate. It lists every defect found and the category of each. It is not a repair estimate and it is not a demand that the work be done at that garage — it is a statement of what the car does not comply with.
The result is on the DVSA database immediately, so it is visible online regardless of the paper. If you lose the sheet you can look the result up on GOV.UK using the registration.
You do not have to have the repairs done there
This is the part people most often do not realise. A test centre has no claim on the repair work. You are entitled to take the VT30 elsewhere, get quotes, and have the work done wherever you like — or do it yourself if you are able.
There is a practical trade-off, though, and it is about the retest. Leaving the car at the centre that tested it usually means a free partial retest. Taking it away and bringing it back later can mean paying again. That is covered in detail in our guide to MOT retest rules, and it is worth understanding before you decide, because the saving on a cheaper repair quote can be smaller than the cost of a second full test.
If a quote feels high, it is entirely reasonable to say you would like to think about it and to ring elsewhere with the VT30 in front of you. Any decent garage expects that.
What to do, in order
- Read the categories, not just the list. Establish whether anything is dangerous. That determines whether the car moves at all.
- Check your existing certificate’s expiry date. If it has not run out, you have more room than you think.
- Ask for the failure explained in plain terms. “Nearside front suspension arm has excessive play” should come with what that means and what it takes to fix.
- Get the price in writing before agreeing to anything.
- Decide where the work happens, factoring in the retest position.
- Book the retest within the window that keeps it free or reduced.
How much will it cost?
The average MOT failure repair sits around £140–£170, but that average hides an enormous range. Rough Birmingham figures:
| Failure | Typical cost |
|---|---|
| Blown bulb | £5–£25 fitted |
| Wiper blades | £20–£40 |
| Tyre | £60–£120 each |
| Brake pads and discs, one axle | £200–£320 |
| Shock absorbers, pair | £150–£400 |
| Suspension arm or ball joint | £120–£280 |
| Exhaust section | £90–£450 |
| Corroded brake line | £100–£250 |
If the total is heading towards what the car is worth, that is a genuine decision point rather than an automatic yes. A garage worth using will tell you honestly when a car is not worth repairing — and we will say so plainly rather than quietly run up a bill.
What if you think the failure is wrong?
You can challenge it. If you believe a car has been failed incorrectly, you can complain to DVSA — there is a formal appeal process, and it has a time limit, so act quickly rather than after the repair. Do not have the work done first and dispute afterwards; once the defect is repaired there is nothing left to inspect.
In practice genuine mis-fails are uncommon, and a second opinion from another garage is usually a faster and cheaper way to satisfy yourself. Bring the VT30 and ask them to look at the specific item.
When should you call a garage?
Straight away if anything is marked dangerous — the car should not be moved, and you may need it recovered rather than driven.
Otherwise, ring with the VT30 in hand and read the items out. Most garages, including us, will tell you over the phone roughly what each one involves and what it should cost, which puts you in a much better position than agreeing to a figure at a counter.
We are a DVSA-approved test centre and a repair garage, so if you failed elsewhere we are happy to quote against your VT30, and we will tell you plainly if we think something has been over-called. MOT testing and repairs in Birmingham — open seven days a week.
Frequently asked questions
Can I drive my car after it fails an MOT?
It depends on the category and on your old certificate. If any defect is recorded as dangerous, you must not drive it at all — not home, not to another garage. If the defects are major only and your previous certificate has not yet expired, you can generally still drive, though you remain responsible for the car being roadworthy. If the certificate has expired, you may only drive to a pre-arranged repair or a pre-booked retest.
Do I have to have the repairs done at the test centre?
No. The VT30 is a statement of what the car does not comply with, not a repair order. You can take it anywhere, get quotes, or do the work yourself. The one thing to weigh is the retest: leaving the car where it was tested usually means a free partial retest, while taking it away can mean paying for a test again.
What is a VT30?
The refusal of an MOT test certificate — the document you get when a car fails. It lists every defect found and the category of each. The result also goes onto the DVSA database immediately, so if you lose the paperwork you can look it up on GOV.UK using the registration.
What if I think my car was failed unfairly?
There is a formal DVSA appeal process, and it has a time limit, so act quickly. Crucially, do not have the work done first and dispute afterwards — once the defect is repaired there is nothing left to inspect. In practice a second opinion from another garage is usually faster; bring the VT30 and ask them to look at the specific item.
How much does an MOT failure usually cost to fix?
The average is around £140 to £170, but the range is wide. A bulb is £5 to £25 fitted, wipers £20 to £40, a tyre £60 to £120, brake pads and discs on one axle £200 to £320, and a pair of shock absorbers £150 to £400. If the total approaches what the car is worth, that is a real decision rather than an automatic yes.
