What is a full car history check?

A full car history check (sometimes called a provenance check) is a paid report that brings together records held in private databases — outstanding finance, damage and total-loss history, theft records, mileage rollbacks cross-checked from multiple sources, plus previous owners and import history. It goes beyond the free DVLA and MOT data anyone can look up, covering the risks that aren't in any public feed.

Do I need a paid history check if I've done a free car check?

They cover different things. A free car check confirms the DVLA details, MOT history, mileage at each MOT, tax status and recalls — enough to spot many problems before you view a car. A paid report adds the records that sit in private databases: finance owed, damage and write-off history, theft records and cross-referenced mileage. The smart approach is free first to filter, then a paid report on the car you're serious about.

How much does a full car history report cost?

A carVertical report starts from around £16.79 per report with the Free Plate Check reader discount (20% off). Either way it's a tiny fraction of a used car's price — a single undisclosed finance agreement or a hidden write-off can cost you thousands, or the car itself.

What can't a history check tell you?

No history check — free or paid — can assess mechanical condition, unclaimed accident damage that was repaired privately, or how the car was driven. For those you need a physical inspection by a qualified mechanic. A history report covers the paperwork; an inspection covers the metal.

Full Car History Check: What a Paid Report Reveals That a Free Check Can't

If you're buying a used car, you'll do two kinds of checking. The first is free and instant: look up the registration and you'll see the car's MOT history, mileage at each test, tax status, and DVLA details. That alone catches a lot of problems. But there's a second layer — the records that live in private databases, not public government feeds — and that's where a full car history check earns its keep.

This guide explains exactly where a free check stops, the things only a paid report reveals, and when it's worth paying for one.

What a free car check already covers

Start here on every car, because it costs nothing and takes seconds. A free car check pulls official DVLA and DVSA data and shows you:

MOT history — every test, pass or fail, with the advisories and failure reasons going back years
Mileage records — the odometer reading logged at each MOT, so you can see the trend
Tax status and whether the car is ULEZ compliant
Outstanding recalls and the basic vehicle details — make, model, engine, colour, fuel

That's a genuinely powerful first screen. If the MOT history is patchy, the mileage jumps around, or the details don't match the advert, you can walk away before spending a penny. For a full walkthrough, see our guide to essential checks before buying a used car.

But a free check can only show what's in the public record. It cannot see inside the private finance, insurance and police databases — and that's where the most expensive surprises hide.

The things only a paid report reveals

A full vehicle history report queries the databases that aren't publicly accessible. Here's what it adds:

Outstanding finance. Around a third of used cars are bought on finance, and if money is still owed, the finance company — not the seller — legally owns the car. Buy it and the car can be repossessed, with you out of pocket. This is the single most common reason to run a paid check. (More on this in our guide to checking a car for outstanding finance.)
Damage and write-off history. If a car has been written off and repaired, that history matters — a repaired write-off can be perfectly safe, but it's worth significantly less and the repair quality counts. A free check can't see this; a paid report surfaces recorded damage and total-loss events. (What Cat N and Cat S mean.)
Theft records. A paid report checks the car against police and insurance data for theft markers — and flags signs that an identity has been tampered with. (How to check if a car is stolen.)
Mileage rollbacks. "Clocking" — winding back the odometer — is still common. A report cross-references mileage from many sources, catching discrepancies that a single MOT-history lookup can miss, including cars wound back before they were imported. (How to spot a clocked car.)
Previous owners and ownership changes. How many hands a car has passed through, and how often — useful context the advert rarely volunteers.
Import history and recorded images. Whether the car was imported, plus photos and specification details that help you confirm you're looking at the right vehicle.

None of these sit in the free DVLA or MOT feeds. They're the gap a paid report fills.

When a full history check is worth it

You don't need a paid report on every car you glance at — that's what the free check is for. Pay for one when:

You're spending more than a couple of thousand pounds. The cost is trivial against the purchase price, and against the cost of getting it wrong.
You're buying privately. There's no dealer protection, so the paperwork is entirely on you to verify.
Something feels off. A price that's too good, a seller who's vague about history, an MOT record with gaps — these are exactly the cars worth checking properly.

The most cost-effective approach is layered: run a free check on every car to filter, then a single paid report on the one you actually intend to buy.

How to run a full history check

Once you've used the free check to narrow down to a serious contender, a full report is the next step. We use and recommend carVertical for the paid layer — it cross-checks over 1,000 data sources across 45+ countries for mileage rollbacks, outstanding finance, theft records, damage and total-loss history, previous owners and more, summed up in an overall "carVertical Score". Free Plate Check readers get 20% off (from around £16.79 a report).

carVertical provides and sells the report; we may earn a commission, at no extra cost to you.

Pair the report with a physical inspection from a qualified mechanic for anything significant, and you've covered both sides: the paperwork and the metal.

The bottom line

A free car check gives you a remarkable amount for nothing — MOT history, mileage, tax, ULEZ, recalls and valuation — and it's the right first move on every car. But it can only show the public record. For finance, damage, theft and mileage fraud, you need a full history report that reaches the private databases. Used together — free to filter, paid to confirm — they give you the most complete picture of a car before you hand over any money.

Start with a free car check now, and add a full report on the car you're serious about.
