The Complete Vehicle History Check Guide

A full vehicle history check combines free DVLA and DVSA data with paid commercial data to show you whether a car is taxed, has a valid MOT, has been written off, is stolen, or has outstanding finance. The free parts cover the basics, but the paid parts cover the risks that cost you the most money.

What is a vehicle history check?

A vehicle history check is a report that pulls together information about a car from multiple sources. In the UK, the two main official sources are the DVLA (Driver and Vehicle Licensing Agency) and the DVSA (Driver and Vehicle Standards Agency).

The DVLA holds registration and tax data. The DVSA holds MOT test records. Both are public databases, and you can access them for free. A history check simply presents that data in one place, alongside additional commercial data that is not free.

No single check covers everything. The free checks on this site use the official APIs, while paid checks add finance, stolen, and write-off data from commercial providers.

What does the free DVLA and DVSA data cover?

The free check on this site pulls from the DVLA Vehicle Enquiry API and the DVSA MOT History API. It gives you the following information:

• Tax status and tax due date
• MOT status and expiry date
• Full MOT history, including every test result and recorded mileage
• Make and model
• Colour
• Fuel type
• Engine size
• CO2 emissions
• Date of first registration

This data is accurate and official, but it is limited. It will not tell you if the car has been stolen, written off, or has finance owing on it. Those records are held by other organisations.

What does only a paid check cover?

A paid vehicle history check adds several layers of data that the free check cannot access:

On this site, paid checks for finance, stolen, and write-off data are marked as coming soon. Until then, you can use a third-party provider for those specific checks.

How do you read each section of a history check?

Start with the tax and MOT status. If the tax has lapsed, the car cannot be driven legally on public roads. If the MOT has expired, the car cannot be driven at all except to a pre-booked MOT test.

Next, look at the MOT history. You want to see a consistent pattern of passes and, ideally, no major failures. Pay attention to advisories, which are minor issues noted by the tester. If the same advisory appears year after year, it has not been fixed.

Check the recorded mileage at each MOT. A reading that is lower than a previous reading is the clearest sign of clocking. For example, if the car showed 60,000 miles in 2020 and 55,000 miles in 2022, the odometer has been wound back.

Finally, look at the vehicle details. Make sure the colour, fuel type, and engine size match what the seller is advertising. A mismatch could indicate a cloned identity or a car that has been significantly modified.

Which checks matter most for a private purchase versus a dealer purchase?

For a private purchase, the finance check is the most important. Private sellers are not regulated, and there is no legal requirement for them to disclose outstanding finance. If you buy a car with finance on it, the lender can take it back.

For a dealer purchase, the finance check is less critical because dealers are required to sell cars free of finance. However, you should still check the write-off history. Some dealers sell category S or N cars without making it clear, and these cars can have hidden structural damage.

For both, the stolen vehicle check is essential. If the car is stolen, you will lose it regardless of whether you bought it from a dealer or a private seller.

What can no check tell you?

No history check can tell you the true mechanical condition of a car. A car can pass an MOT and still have serious issues that the test does not cover, such as a worn clutch, a faulty gearbox, or engine problems.

No check can tell you whether the car has been in an accident that was not reported to an insurer. If the seller repaired the damage privately, there will be no record of it.

No check can tell you how the car was driven or maintained. Two identical cars with the same mileage can be in completely different conditions depending on how they were treated.

For these reasons, a history check should be part of your process, not the whole process. You should also arrange an independent inspection or take the car to a trusted mechanic before you buy.

What is the practical order to run the checks in?

Run the free checks first, because they cost nothing and can eliminate a car quickly. Start with the tax check to see if the car is taxed, then run the MOT check to see if it has a valid certificate and to review the full history.

If those come back clean, run the mileage check to look for any inconsistencies in the recorded readings. This is a free check that can save you from buying a clocked car.

If you are still interested, run a paid check for finance, stolen, and write-off data. This is the point where you spend money, but it is worth it for a car that costs thousands of pounds.

Finally, use the number plate check to confirm the registration matches the vehicle details, and the VIN check to make sure the VIN on the car matches the V5C and the MOT records.

What should you keep as a record?

Save or print the results of every check you run. Keep the MOT history, the tax status, and any paid check reports. These documents form part of your evidence if there is a dispute later.

If you buy the car, keep the receipt, the seller's contact details, and a copy of the V5C. If the car turns out to be stolen or has finance on it, you will need this paperwork to support a claim against the seller.

For ongoing peace of mind, you can use the combined MOT and tax check to monitor the car's status before each renewal date. This helps you avoid the fines for driving without tax or MOT.
