MOT failure: what happens next

Check whether the defect is dangerous, major or minor

The test produces four kinds of entry, and only two of them cause a failure. A dangerous defect means a direct and immediate risk to road safety or a serious impact on the environment. A major defect may affect safety, put other road users at risk or harm the environment. Either one fails the vehicle. A minor defect has no significant effect on safety and does not fail it. An advisory is a note that something is on its way to becoming a problem.

That distinction decides the next hour of your day, so ask the tester which category each item sits in rather than accepting a list of faults. The wording is on the printed result and in the MOT record online, and the two should match. Minor items and advisories are useful planning information, and they are also the items to be sceptical about if they arrive attached to a quote you did not ask for.

A refusal of a test certificate is recorded against the vehicle, so a fail is public. Anyone can pull the history up later on the MOT history service and see what failed, what was noted as minor and what the mileage was on the day. That cuts both ways: it is the reason a buyer can check your car, and it is the reason you can check theirs.

• Dangerous: fails. Do not drive the vehicle at all until it is repaired.
• Major: fails. A valid old certificate is not enough on its own; the vehicle must remain roadworthy.
• Minor: passes. Repair as soon as possible; it is still a recorded defect.
• Advisory: passes. Monitor and repair if necessary; it is not a promise of remaining life.

Can I drive away after an MOT failure?

GOV.UK says you can take the vehicle away if your current MOT certificate is valid and no dangerous problems were recorded. It also requires the vehicle to meet roadworthiness standards at all times. Read those conditions together: a major classification and an unexpired certificate are not a guarantee that every proposed journey is lawful.

For a car tested before expiry, start with the failure itself. Ask what it means for safety now and what work is needed before driving. A dangerous defect means repair before driving, regardless of how much time remains on the old certificate. GOV.UK gives a fine of up to £2,500, three penalty points and a possible ban for driving after a dangerous failure. The offence concerns the state of the vehicle, not simply its paperwork.

Where the certificate has expired, GOV.UK's retest guidance permits journeys to have failed defects fixed or to a pre arranged test, provided the car still meets roadworthiness standards. Do not use that allowance to drive a dangerous vehicle to another garage. Arrange suitable recovery or repair where it stands. Insurance and any separate tax restriction must also be satisfied before a road journey.

1. 1Read every failure item and ask the tester to explain its classification and its effect on safety.
2. 2Check whether the old certificate is still valid, without treating it as proof of roadworthiness.
3. 3Decide where repairs will happen and how the car can lawfully reach that place.
4. 4Arrange recovery for a dangerous vehicle and confirm storage arrangements until it is collected.

A retest can be free, half price or full price

Leave the vehicle at the test station, have the repair done there, and have it retested within ten working days, and the retest is free. The vehicle has to stay on site for the whole period. This is the cleanest route and the one the fee rules were written around.

Take the vehicle away for repair and have it retested at the same station before the end of the next working day on which testing is carried out, and the partial retest is free if all the failures are on DVSA's specified list. It includes lamps but excludes headlamp aim, and includes seatbelts but excludes their anchorages. Wheels and tyres qualify for cars but not motorcycles. Check the exact failure, rather than assuming every fault involving a named part qualifies.

Return to the same station for a retest within ten working days after taking the car elsewhere for repair, and a partial retest may be charged at up to half the statutory maximum for its class. For a car the calculation is £54.85 divided by two, or £27.425 before a charge is expressed in whole pence. This is a calculated ceiling, not a national flat price. A different station or a missed qualification period means a full test, for which the station may charge up to the class maximum. Only one partial re examination is permitted per full test.

• Repaired at the station, retested within ten working days: free.
• Taken away, back before the end of the next working day, listed items only: free.
• Taken away, back within ten working days: partial retest, up to half the maximum fee.
• Back after ten working days, or at a different station: full test at the full fee.

You can choose where the repairs are done

The station that failed the car has the advantage on fees and the disadvantage of being the only quote in the room. For a cheap, listed item there is rarely anything to gain by moving the car. For a large job, a second price from an independent garage often saves more than the retest fee costs, and you can still return within ten working days for the partial retest.

Ask for the failure sheet before you take a quote anywhere. It names the defect and the location on the vehicle, which is what another garage needs in order to price the same job rather than a bigger one. If a quote comes back covering items that were minor or advisory rather than the ones that actually failed, separate the two lists and decide on each one on its own merits.

You can challenge a result you believe is wrong. DVSA takes complaints and appeals about MOT tests, and it works best if the vehicle is left exactly as it came out of the test until the matter has been looked at. That is a real trade off, because the car cannot be driven in the meantime.

The vehicle must pass before the new certificate is issued

A repair invoice is not a pass. The vehicle needs the appropriate retest and a recorded pass before a new certificate exists. Read its expiry rather than calculating from the failed test date: the timing of the successful test and the rules for preserving the old renewal date matter. If the old certificate expired during repairs, do not assume the new one recreates the unused appointment date.

The tax is the other loose end. You cannot tax a vehicle that needs an MOT and does not have one, and GOV.UK says the MOT information can take up to two days to update for taxation. Keep it off the public road while any outstanding tax is resolved. If repairs leave it untaxed, follow the SORN requirements; a declaration does not remove responsibility for previous use or authorise kerbside storage.

1. 1Agree repairs against the exact failure items and ask for approval before extra work is added.
2. 2Confirm that the retest appointment itself falls within the relevant working day deadline.
3. 3After testing, check the pass, registration, mileage and new expiry in the official record.
4. 4Keep the repair invoice and resolve tax and insurance requirements before returning to normal road use.

Is the retest free if my car only failed on a bulb?

The quick return concession depends on the recorded failure items, not the repair bill or how simple a job looks. A lamp and a headlamp aim fault are treated differently for this purpose. Ask the station to confirm that every failure qualifies before taking the vehicle elsewhere. A separate suspension or braking failure would prevent reliance on the listed items concession even if the lamp is also repaired.

Book the retest when you arrange the repair. Returning the car to the forecourt is not the same as completing the retest by the deadline. Confirm when testing takes place, especially around weekends and bank holidays. The safer way to plan is to obtain the station's actual last qualifying appointment, rather than relying on a calendar calculation and discovering that no tester is available.

Should I leave the car at the test centre for repairs?

The other free route suits a vehicle that remains with the testing station for repairs. The important facts are continuous presence at the station and the completed retest within the allowed period. If parts are delayed beyond that period, the car does not retain free retesting indefinitely. Ask about availability before accepting a repair schedule which assumes the concession will still apply.

A free retest does not necessarily make that station's overall repair proposal the best fit. Compare the actual repair scope, timing, transport and any agreed storage costs. A cheaper repair elsewhere may still cost less overall despite a chargeable retest, but there is no published saving that applies to every car. Use written quotations for your own fault instead of adding a generic repair estimate to the statutory test fee.

How do I appeal an MOT failure?

If you think the failure is wrong, first discuss the result with the test centre before anyone starts repairs. GOV.UK requires a failure appeal to reach DVSA within fourteen working days of the test. It says DVSA will contact you within five days to discuss the appeal. Do not confuse that appeal deadline with the shorter period for a qualifying partial retest: they are different processes with different purposes.

DVSA may arrange its own recheck, for which you pay the full test fee again. GOV.UK says that fee is refunded if the appeal succeeds. Preserve the car's condition until the appeal finishes and ask about safe transport if the car cannot be driven. Keep the failure record, your correspondence and any photographs that help identify the disputed item. An appeal is about the test decision; it is not an automatic refund of all repair or inconvenience costs.

The same route works the other way round, which matters if you have just bought a car with a fresh MOT and found faults the test should have caught. GOV.UK gives 28 days from the test to appeal a pass you think should have been a failure, or 3 months where the problem is corrosion. DVSA will contact you within 5 days, and you do not pay the test fee again for that recheck.

1. 1Discuss the disputed failure with the station before authorising repairs.
2. 2If unresolved, submit the official complaint form to DVSA within 14 working days of the test.
3. 3Leave the vehicle unrepaired while the appeal is considered and agree any recheck arrangements with DVSA.
4. 4Use the resulting inspection report to decide the next repairs or testing action, keeping any separate invoice dispute distinct.
