What is an MOT history and why it matters
The MOT test is a legal requirement for most UK vehicles over three years old. Each time a car passes or fails, the result is recorded on the DVLA database and can be viewed online. A complete MOT history shows every test date, mileage at test, any failures, advisories and the date the next test is due. By reviewing this record you can spot patterns that suggest hidden problems before you sign a purchase agreement.
Step‑by‑step MOT history checklist
Use the following checklist when you look at a vehicle’s MOT data. Tick each item and note any concerns.
- Test dates and frequency: The car should have an MOT every 12 months. Gaps longer than a year may indicate the vehicle was off the road or that the seller is hiding a period of disuse.
- Mileage at each test: Consistent mileage growth (roughly 10‑15 000 mi per year) is normal. Sudden jumps or a flat line for several years could be a sign of clocking or odometer tampering.
- Failures and advisories: Record any failed items and the severity of each advisory. Repeated failures on the same component (e.g., brakes, suspension) suggest a chronic issue that may not have been fully repaired.
- Pass with no failures: A clean record is reassuring, but still check the mileage trend and the age of the vehicle.
- Next MOT due date: Ensure the next test is due after your intended purchase date, giving you time to arrange a fresh MOT if needed.
How to read the MOT details
The official MOT history page shows a table with columns for Test Date, Mileage, Result (Pass/Fail), Failure Reason and Advisory. Hover over each failure to see a description of the problem. Pay particular attention to safety‑critical failures such as brakes, steering, tyres and emissions.
Cross‑checking other vehicle records
While the MOT record is a vital piece of the puzzle, it does not tell the whole story. Combine it with other checks to get a full picture:
- DVLA vehicle information: Confirms the make, model, engine size, colour and registration date.
- PNC stolen marker: A stolen‑vehicle flag must be cleared before a sale can be completed.
- Insurance write‑off categories (Cat A, B, S, N): A car written off as Cat S or N may have structural damage that was repaired; Cat A or B indicates total loss and the vehicle should not be on the road.
- Outstanding finance: An unpaid loan can be transferred to a new owner, leaving you liable.
- Previous keepers: Multiple short‑term owners can be a red flag for hidden problems.
Spotting mileage clocking
Clocking is illegal and can dramatically reduce a car’s value. Look for these warning signs in the MOT history:
- Identical mileage readings across several consecutive tests.
- A mileage that is unusually low for the car’s age (e.g., under 30 000 mi on a 10‑year‑old vehicle).
- Large mileage jumps that do not match typical annual usage.
If any of these appear, request a full service history and consider a professional mileage verification.
When to get a fresh MOT
If the most recent MOT is close to expiry, arrange a new test before finalising the purchase. A fresh MOT gives you peace of mind and a legal safety certificate for the next year.
Final tip
All the data above is publicly available, but the quickest way to view a vehicle’s MOT history, registration details and any outstanding finance is to enter the registration number on motorpeek.com. A single search gives you a clear, easy‑to‑read report that you can download and keep for your records.
Frequently asked questions
How often should I check a car's MOT history before buying?
You should review every MOT record from the first test onward. Look for consistent mileage growth, any repeated failures and the date of the next test to ensure the car is road‑worthy.
Can a car pass its MOT but still have hidden problems?
Yes. An MOT only checks items required by law, so cosmetic damage, interior wear or non‑safety faults may not be recorded. Combine the MOT check with a full service history and a professional inspection.
What does an advisory on an MOT report mean?
An advisory is a warning about a component that is not yet a failure but may need attention soon. Repeated advisories on the same part can indicate a developing issue that could become a costly repair.
