Free vs Paid Car Checks: What's the Difference?

By Matthew Croxford · 30 Sep 2026 · Updated 20 Oct 2026

Short answer: A free reg check uses DVLA and MOT data to show tax status, MOT history, mileage trail and recalls, ideal for a quick sanity check. A paid history check, using data provided by Experian, adds outstanding finance, write-off status, stolen markers, previous keepers and import or export history. Use the free check first, then pay before committing to buy.

Before buying a used car, it pays to know exactly what you are looking at. There are two broad types of online car check in the UK, a free reg check and a paid vehicle history check, and they answer very different questions. Knowing which one you need, and when, can save you from an expensive mistake.

What a free reg check shows

A free reg check is built from official public records, mainly DVLA vehicle data and the DVSA MOT history. Enter a registration and you can typically see the car's make, model and basic specification, its current tax status, and its full MOT history, including every pass, advisory and failure and the mileage recorded at each test. Many free checks, including our free reg check, also flag any outstanding safety recalls and give a free market valuation.

This is enough to answer a lot of the important early questions. Does the MOT history look honest, with the mileage rising steadily year on year? Are there recurring advisories that hint at a neglected car? Is there an open safety recall that has never been actioned? For spotting a likely clocked car, the MOT mileage trail in a free check is often the single most useful thing you can look at.

What a paid vehicle history check adds

A paid vehicle history check goes into the financial and legal background that public MOT and DVLA records do not cover. Our vehicle history check does this with data provided by Experian, revealing whether the car still has outstanding finance owing on it, whether it has been written off by an insurer, whether it carries a police stolen marker, how many previous keepers it has had, and whether it has been imported, exported or scrapped. It usually includes a VIN and identity check too.

These are the risks that can cost you the car or the money. Buy a car with outstanding finance and the finance company may still own it. Buy an undisclosed write-off and you may have paid far too much for a car that is worth much less. None of this shows up in a free check, because it does not live in MOT or DVLA records.

Which one do you need?

For a quick sanity check, or a car you are only mildly interested in, a free reg check is usually enough to decide whether to look closer. The moment you are seriously considering handing over money, a paid history check is the sensible step, because the things it reveals are exactly the things that turn a good deal into a costly one.

A practical approach is to use both in sequence: run the free reg check first to confirm the MOT history, mileage trail and tax status, and if the car still looks right, add the paid history check before you commit. For less than the cost of a full tank of fuel, it is the difference between hoping a car is what it seems and knowing.

What to look for in any car check

Whichever you use, a few things matter. Check that the data comes from recognised sources rather than estimates, so DVLA and DVSA for the free records and a named provider such as Experian for the paid history. Check what is and is not included, as not every check covers the same ground. And remember that a check tells you about the car's recorded history, not its current mechanical condition, so it works best alongside a proper inspection or test drive.

You can run a free reg check on any car in seconds, and add a full history check when you are ready to buy.

Frequently asked questions

What does a free reg check show you? It uses DVLA and DVSA data to show a car's make, model and specification, current tax status, full MOT history with mileage at each test, outstanding safety recalls and a free market valuation.

What does a paid vehicle history check reveal that a free check does not? Using data provided by Experian, it shows outstanding finance, insurance write offs, police stolen markers, the number of previous keepers, and whether the car has been imported, exported or scrapped.

Do I need both a free and a paid car check? A free reg check is usually enough for a quick look, but once you are seriously considering buying, a paid history check is sensible since it reveals finance, write off and stolen marker issues.

Does a car check tell you about a car's mechanical condition? No, a check only tells you about the car's recorded history, so it should be used alongside a proper inspection or test drive.
