Car History Check: Where Each Record Really Comes From
A car history check combines records from five sources: DVLA for the car's identity and keeper and plate changes, DVSA for the MOT history and the mileage at each test, insurers for write-offs, finance companies for outstanding agreements, and the police for stolen markers. Each has a gap. A write-off only exists if an insurer handled a claim, and a Category N car keeps its ordinary V5C, so only the history check shows it.

A car history check reads like one report, but it is five different bodies answering five different questions about the same registration. Once you know which body supplies which line, two things become clear: what a clean result actually proves, and why some cars with a serious past look perfectly ordinary on paper.
What does a car history check show?
Citizens Advice describes a private check as one that tells you whether the car has been reported stolen, whether money is still owed on it, whether it has been in a serious accident, whether the mileage is correct, and whether it was written off and returned to the road. It puts the cost at up to £20 [1]. Here is where each of those answers comes from:
| Record | Who holds it | Free? | The gap |
|---|---|---|---|
| Identity, tax, first registration | DVLA | Yes | Says what the car is, not what happened to it |
| Keeper and plate changes | DVLA | No, paid check | Counts keepers, does not name them |
| MOT results and mileage at each test [4] | DVSA | Yes | Nothing before the first MOT, nothing between tests |
| Write-off and category | Insurers, reported to DVLA [2] | No, paid check | Only exists if an insurer handled a claim |
| Outstanding finance | Finance companies | No, paid check | Not a government record at all |
| Stolen marker | Police | No, paid check | Only what was reported |
The free rows are covered in our guide to the free car check. The rest of this page is about the paid rows, and the write-off row most of all, because that is where the law leaves the most interesting gaps.
Where does the write-off record come from?
From a legal duty on the insurer. When an insurer decides a car it insures would cost more to repair than it was worth before the accident, or it has to replace the car under the policy, it must tell DVLA whether the car is suitable for repair and, since 20 February 2018, whether the damage was structural [2]. That decision is what becomes the category [3]:
- Category A: cannot be repaired, the whole car is crushed.
- Category B: cannot be repaired, the body shell is crushed but parts can be salvaged.
- Category S: repairable after structural damage.
- Category N: repairable after non-structural damage.
Notice who the duty falls on: the insurer, and fleet keepers who carry their own risk [2]. A private owner who pays to fix a crash without claiming creates no write-off record at all. A clean write-off result means no insurer declared the car a total loss. It does not mean the car was never damaged.
Why can a Category N car have a perfectly normal V5C?
Because of how the paperwork rule is written. After notifying DVLA, the insurer must destroy the registration document unless the car is suitable for repair and has no structural damage [2]. That exception is Category N.
The practical result, set out on GOV.UK, is that a Category S car kept by its owner gets its category recorded in the log book by DVLA, while the keeper of a Category N car can simply keep the log book they already have [3]. So a buyer looking only at the V5C will see the S, and will see nothing at all on an N.
Where do the mileage and keeper records come from?
The mileage record is the MOT history: every test logs the reading, and for cars the online history goes back to tests since 2005 [4]. That makes it strong evidence of clocking when readings go down or stall, and useless for a car under three years old, which has not had a test yet. Our mileage check reads the entries for you.
Keeper and plate changes come from DVLA's own record. A paid check reports how many keepers the car has had and when the registration changed, not who they were, which is the useful part anyway: four keepers in two years is a question worth asking. Our keeper history page explains how to read it.
What happens if you buy a car that still has finance on it?
Less than many people fear, but more than you want. Citizens Advice says a private buyer often keeps a car still on hire purchase or conditional sale, which is called good title, if they did not know about the agreement, bought in good faith and were the first private buyer from the person who had the agreement. It is then for the finance company to prove otherwise [5].
That protection is a defence, not a plan. Arguing about good title with a lender takes letters, proof of purchase and time, and it does not help a buyer who knew or should have known. A history check before paying turns the whole question into a two minute answer. A Caraxle Full Check costs £12.99 and covers outstanding finance, write-off and stolen records alongside the MOT and DVLA data.
What will no history check tell you?
Condition. No record describes the clutch, the corrosion or the quality of a repair, and damage nobody claimed for is invisible by design. Citizens Advice suggests an independent inspection, at around £120 to £250, if you are still unsure after the checks [1], and our car check guide covers what to look at on the V5C and the car at the viewing.
The short version
A history check is only as good as the duties behind each line. DVLA and DVSA record what the car is and how it did at its MOTs. Insurers report write-offs, but only for claims they handled, and a Category N car keeps an ordinary V5C. Finance and stolen records come from outside government altogether. Read the result knowing who wrote it, and a clean check means exactly what it should: none of the sources behind it had anything to report.
Frequently asked questions
- What does a car history check show?
- Whether the car is recorded as stolen, whether finance is still outstanding, whether an insurer wrote it off and in which category, whether the mileage is consistent with its MOT history, and its keeper and plate changes. Citizens Advice puts the cost of a private check at up to £20.
- Will a Category N write-off show on the V5C?
- Not necessarily. When an insurer decides a car is repairable without structural damage, it does not have to destroy the registration document, and the keeper of a Category N car can keep the log book. A Category S car gets its category recorded in the log book. A history check shows both.
- Can a car have been badly damaged and still show no write-off?
- Yes. The duty to report a write-off sits with the insurer that handled the claim, and with fleet keepers who insure themselves. Damage repaired privately, without a claim, never becomes a write-off record.
- What if I buy a car that still has finance on it?
- You may still own it. Under hire purchase and conditional sale, a private buyer who bought in good faith without knowing about the agreement, and was the first private buyer, usually gets good title, and the finance company has to prove otherwise. Checking first is still far simpler than arguing afterwards.
- Is a car history check worth it?
- For any car you are serious about, yes. The free government services cover tax, MOT and the vehicle record, but not finance, write-offs or stolen markers, and those are the records that can cost you the car or a large share of its value.
