Undergoing an MOT failure can be stressful and confusing for any UK driver. This guide provides a clear, legal and practical roadmap to help you navigate the process with confidence, from reviewing the failure report right through to retesting and avoiding future issues.
1. Understand the Result
Your MOT will result in either a pass or a failure. A failure means serious ‘dangerous’ or ‘major’ defects have been identified, rendering your vehicle unroadworthy until repairs are made. You will be issued a VT30 refusal certificate outlining these issues, plus any minor advisories to monitor in future tests.
2. Review Your VT30 Refusal Certificate
The VT30 is crucial – it lists the exact items that caused failure. Take time to digest it and, if anything seems unclear, call the test centre for an explanation. This will help you decide which issues require urgent repair and how best to proceed with them.
3. Know When You Can and Cannot Drive
You may legally drive the vehicle only if your previous MOT is still valid and no dangerous defects were listed. If either condition is not met, you cannot drive it until the faults are fixed. Failure to comply could result in fines up to £2,500, three penalty points or an unlimited fine in case of extremely dangerous faults, plus potential insurance invalidity.
4. Arrange Repairs
You have several options:
• Stay at the original test centre – many offer same‑day repairs and a free retest within ten working days.
• Take the car elsewhere – you can have it fixed at another garage, but to get a qualifying retest at the original centre within the ten‑day window you might pay a reduced partial retest fee.
• Miss the ten‑day window – you will need to pay the full MOT fee again and undergo a full MOT at any centre.
Pelase ensure all repair invoices are retained in case of future reference or appeal.
5. Handle the Re‑Test
• Partial retest: If done at the original centre within ten working days, you likely won’t be charged or might pay a reduced fee. This retest covers only the failed items.
• Full retest: If beyond ten working days or at a different centre, a full MOT test must be paid for in full.
• If repaired on same day and returned by next working day, a free retest may apply.
6. After a Successful Retest
Upon passing, you will receive a VT20 certificate. Update your vehicle logbook, ensure tax and insurance are current and legal, and resume normal driving.
7. If the Car Fails Again
Should the car fail again, repeat the repair process. If you suspect errors in the result, don’t refill issues before a formal appeal. See the next section.
8. What to Do If You Disagree
• Speak with the test centre manager – they may review the result.
• For formal appeal, submit a VT17 appeal form to the DVSA within 14 days for mechanical faults (longer for corrosion issues). This must be done before any alterations. If successful, fees may be refunded.
9. Prevent Future MOT Failures
• Conduct a pre‑MOT health check: check lights, tyres, wipers, windscreen, mirrors, horn, seat belts, doors, dashboard warnings and number plates. Pay attention to any advisories noted in previous tests.
• Aim to book your MOT up to one month before expiry to allow time for repairs without leaving a gap.
