A used car check is the one thing that tells you, before you pay, whether a second hand car is what the seller says it is: who really owns it, whether it has been written off or stolen, whether the mileage adds up, and whether the car in front of you is the car on the paperwork. Enter the registration in the search box above. The free check shows the DVLA details, tax and MOT status, the full MOT history with mileage readings and our running-cost and ULEZ estimates straight away. The full report adds the buyer's checks: outstanding finance, insurance write-offs, police stolen markers, VIN and engine number match, previous keepers, plate changes and a mileage anomaly check, in one report that opens on screen and is emailed to you.

How to check a second hand car in three steps

  1. Free check first (one minute). Run every car you are considering through the free check before you contact the seller. It rules out cars with a failed or missing MOT, a mileage that goes backwards, SORN or a running cost you had not budgeted for.
  2. Full report on the shortlist. Once a car is worth a journey, get the full report. It is the only way to see finance, write-off, stolen and keeper records before you meet the seller.
  3. See the car with the report in your hand. Match the VIN, the V5C, the mileage and the seller's story against the record, then do the physical checks and the test drive. Pay only when everything agrees.

The free check: the first 60 seconds

The free check reads the DVLA vehicle record and the DVSA MOT history for the registration you enter. Use it to rule cars out fast:

  • Is it the car described? Make, model, colour, fuel type, engine size, year of manufacture and the month of first registration.
  • MOT history: every test since 2005 with the result, advisories and failure reasons. Repeated advisories for corrosion, suspension or tyres show how the car has been looked after; a sudden set of structural failures can point to accident damage.
  • Mileage trend: the mileage at every MOT, in order, plus the average per year. A reading lower than the one before is the classic sign of a clocked car. See MOT history and mileage check.
  • Tax and SORN: whether the car is taxed, the due date, or whether it is declared off the road. Tax does not transfer to you, so you will tax it on the day you buy.
  • ULEZ and running costs: the likely ULEZ status from the Euro standard and fuel type, and an estimate of fuel, tax and MOT costs for a year, so you compare cars on what they cost to run, not just the price. More in car running costs check.
  • How many people have checked this car recently, which tells you whether it is being shopped around.

Full vehicle check: the buyer's checks in order of money at risk

The full report runs the searches that decide whether you keep the car and your money, here in the order they tend to cost buyers most.

CheckWhat the report showsWhy it costs the buyer
Outstanding financeWhether an HP, PCP, conditional sale or loan is recorded, the lender, the agreement type and date.Until it is settled the lender usually owns the car and can recover it. 16.7% (about 1 in 6) of the cars our customers checked in full had finance recorded.
Insurance write-offCat S, Cat N or the older Cat C and D, the loss date and cause, damaged areas where recorded.A write-off is worth less, can be harder to insure, and may hide a poor repair. 13.4% (about 1 in 7) of cars checked in full had a write-off recorded.
Stolen markerWhether the car is recorded as stolen on the Police National Computer, with the date and force.A stolen car is returned to its owner or insurer. You lose the car and the money.
VIN and engine numberThe chassis and engine numbers held against the registration.If the VIN on the car does not match, you may be looking at a clone or a car assembled from written-off parts.
Previous keepersHow many keepers, the date of the last change and the V5C issue history.Many keepers in a short time, or a keeper change that does not fit the seller's story, points to a car being passed on with a problem.
Plate changesPrevious registrations and when they changed.A new plate can be a private plate, or a way to break the link to an old history. The dates tell you which.
Mileage anomalyA flag where a recorded mileage is lower than an earlier one.A clocked car is worth less and may be far more worn than it looks.

The full report also carries the car's specification, performance figures, weights and dimensions, fuel economy and recorded road tax cost. See every section in the sample car history report, and the free and full checks side by side on our car history check page.

Instant car check: what "instant" really means

Searches for an "instant car check" mean one thing: no waiting. The free check queries the DVLA and DVSA records the moment you press search, and the result appears on screen in a few seconds. The full report runs the finance, write-off, stolen and keeper searches as soon as your payment is confirmed, and normally opens within seconds, with a copy sent to your email. "Instant" does not mean "for ever": finance can be taken out, and a car reported stolen, at any time. Run the check on the day you pay, not the day you first see the advert.

Buying from a dealer or a private seller

From a dealer: the Consumer Rights Act 2015 says the car must be of satisfactory quality, as described and fit for purpose, and consumer protection law stops a dealer hiding known faults or history. A dealer should tell you about a write-off record or outstanding finance, and should settle finance before the sale. Still run the check: it is your evidence if the description turns out to be wrong.

From a private seller: the law expects far less. The seller must have the right to sell the car and must describe it honestly, but there is no duty to volunteer its history and no right to return it because it turns out to be a poor car. That is why the full report and your own inspection carry the whole load in a private sale. A private buyer who buys a car with hidden finance in good faith is usually protected by the Hire Purchase Act 1964, but proving good faith is far easier when you can show a check run before you paid.

Checks before buying a used car that no record can make

A clean history check means the databases hold nothing against the car. It does not mean the car is in good condition. Use the report to decide which cars to see, then spend time on the car itself:

  • Match the VIN (base of the windscreen, door frame) with the V5C and the report. Our guide shows where to find the VIN and check it matches.
  • Read the V5C. The seller's name and the viewing address should match the log book; the keeper count should match the report.
  • Service history. Stamps, invoices or a digital record with dates and mileages that fit the MOT readings. How to check it: checking a car's service history.
  • Bodywork and panels. Mismatched paint, uneven panel gaps, overspray on trim and new bolts on the wings point to repairs. Compare with any write-off record and the MOT advisories: MOT advisories explained.
  • Test drive on a mix of roads, radio off, and for a car worth real money an independent inspection, which costs a fraction of a hidden fault.

Paying safely for a second hand car

  • Pay only after the check and the inspection agree with the seller's description, and run the full report again on the day if the first one is more than a few days old.
  • Pay by bank transfer to an account in the seller's name, at the seller's address, and get a signed receipt with the registration, VIN, mileage, price and both names.
  • If finance is recorded, pay the lender's settlement figure directly to the lender, with a settlement letter, before any balance goes to the seller.
  • Do the V5C change of keeper together online before you leave, and tax the car before you drive it.

Used car check FAQs

What should I check before buying a used car?

Run the free check for the DVLA details, MOT history and mileage trend; get the full report for finance, write-off, stolen, VIN and keeper records; then match the VIN and V5C on the car, check the service history and bodywork, and test drive it. Pay only when all of it agrees.

Can I check a used car for free?

Yes. The free check shows the DVLA record, tax and MOT status, the full MOT history with mileage readings, and our running-cost and ULEZ estimates. The finance, write-off, stolen and keeper records are in the full report, because each of those searches has a cost.

Is a used car check the same as a full vehicle check?

Yes: both mean a history check on a second hand car by its registration. The full report is the full vehicle check; the free check is its first part.

Do I need the VIN or the V5C to check a car?

No. The registration is enough for both the free check and the full report. Use the VIN on the car to confirm the report matches the car when you see it.

How long is a check valid for?

It shows the records on the day it is run. Finance and stolen records can change at any time, so run it on the day you pay, and never rely on a report the seller hands you.

What if the check finds a problem?

Finance: pay the lender directly or walk away. Write-off: ask for repair invoices and price it accordingly. Stolen marker or VIN mismatch: do not buy and do not pay a deposit.
