Before you spend a single pound on a vehicle history report, you should know that the UK government hands you a genuinely powerful set of checks for free. Most buyers either do not know they exist or use only one of them. Used together, in the right order, the free GOV.UK tools will catch a clocked odometer, expose a lying advert and confirm a car is road-legal, all from your phone before you even ring the seller.
They are not a complete picture, and this guide is honest about where they stop. But they are the first thing you should do on every car you are even mildly interested in, and they cost nothing. Here is exactly what to check, where to find it, and how to read what comes back.
The free GOV.UK checks, and what each one shows
There are four free tools worth knowing, all reachable from gov.uk with nothing more than the registration number.
- Check MOT history (gov.uk/check-mot-history). The complete MOT record going back to 2005: every pass, every fail, every advisory note, and the recorded mileage at each test. This is the single most useful free check in the country.
- Check MOT status. Confirms whether the car currently holds a valid MOT and when it expires.
- Check vehicle tax (gov.uk/check-vehicle-tax). Shows whether the car is taxed or has been declared SORN (off the road).
- DVLA vehicle enquiry. Returns the make, colour, engine size, fuel type and year of manufacture straight from the DVLA record.
You do not need the seller’s permission and you do not need to create an account. All you need is the number plate, which any honest advert will show.
Start with the MOT mileage history: your clocking defence
Clocking, winding back an odometer to make a car look less used, is far from a historic scam. Analysis of UK cars in 2025 suggested roughly one in seven (around 16%) showed a mileage or identity discrepancy. Certain models fare worse than average, with the Nissan Qashqai and Volvo XC60 among the most affected. On a car advertised at 60,000 miles that has really covered 120,000, the difference is worth thousands and hides a lot of hidden wear.
The MOT history is your defence, and it is free. When you open the record, read the recorded mileage at every test from oldest to newest. The numbers should climb steadily, roughly 7,000 to 10,000 miles a year for a typical car. Watch for:
- A figure that drops from one test to the next. That is a red flag that is very hard to explain innocently.
- A long flat spell where mileage barely moves, then a normal jump, which can indicate a period the car was clocked and then reset.
- A current advert mileage lower than the last MOT reading. The car cannot have travelled backwards.
If the plotted mileage does not rise in a straight, believable line, walk away or demand a full explanation with evidence. This one check, done in two minutes, saves more buyers than any other.
Cross-check the advert against the DVLA record
The DVLA vehicle enquiry is a quiet lie-detector. Run the registration through it and compare what comes back against the advert:
- Make and model must match. A “cloned” car often carries plates from a different but similar vehicle.
- Colour must match, or the seller should be able to explain a resprayed or wrapped car. An undeclared colour change is a warning sign.
- Engine size and fuel type must match the spec advertised. A “2.0 diesel” that shows as a 1.6 petrol is either a mistake or something worse.
- Year of manufacture should line up with the plate and the advert.
Any mismatch here deserves a hard question before you go any further. Cloning, where a stolen car is given the identity of a legitimate one, is one of the UK’s most damaging scams, and this free check is the first thing that can flag it.
Confirm it is taxed, MOT’d and legal to drive
Two quick checks finish the free round:
- Check MOT status tells you if the car has a current MOT. Remember a car needs its first MOT at three years old, then one every year, with a maximum test fee of £54.85. Cars over 40 years old are generally exempt.
- Check vehicle tax tells you whether it is taxed or declared SORN. A car that has been SORN for a long time may have sat unused, which brings its own risks of flat batteries, seized brakes and perished tyres.
Neither of these is a dealbreaker on its own, but they help you build an accurate picture of how the car has been kept.
Read the MOT advisories, not just the pass or fail
Most buyers glance at whether each MOT was a pass and move on. The real gold is in the advisory notes attached to each test. Advisories are issues an inspector spotted that were not yet bad enough to fail the car: a tyre wearing thin, a slightly weeping shock absorber, light corrosion on a brake pipe, a bush starting to perish. Read them across several years and a story emerges.
- Recurring advisories for the same fault, year after year, suggest a problem the owner keeps ignoring rather than fixing. That corrosion note from three years ago may now be a costly repair.
- A sudden cluster of advisories in the most recent test can signal a car that has been neglected lately, perhaps in the run-up to sale.
- Big-ticket words to watch for include anything about the chassis, subframe, structural corrosion, or brake and suspension components. These hint at bills to come.
Advisories cost nothing to read and they give you a genuine maintenance history without a single phone call. Take them to the viewing and ask the seller what was done about each one. An owner with the receipts to match is a good sign; one who cannot remember is less reassuring.
A sensible order to run the free checks
To get the most from the free tools with the least effort, work through them in this order before you ever contact the seller:
- DVLA vehicle enquiry first, to confirm the advert is describing the actual car.
- MOT history next, reading mileage and advisories together, which is where most problems surface.
- MOT status and tax last, to confirm the car is currently road-legal.
If anything fails at step one or two, you have saved yourself a wasted journey. If it all checks out, you can call the seller already knowing more about the car than they might expect, which also puts you in a stronger position to negotiate.
What the free checks cannot tell you
Here is the honest limit, and it is important. The free GOV.UK tools do not show:
- Outstanding finance. If the car is still on a finance agreement, the lender owns it and can repossess it from you.
- Write-off category. Whether an insurer has declared the car a total loss, and if so whether it is Category A, B, S or N.
- Stolen markers. Whether the car is recorded as stolen on the Police National Computer.
- Number of previous keepers, plate changes or colour-change history as a full record.
All three of the worst financial disasters, finance, write-off and theft, sit in this blind spot. For a cheap car from someone you trust, the free checks may be enough. For anything worth real money, or any private sale where the story feels slightly off, you need to fill that gap. Our comparison of free GOV.UK checks versus a paid HPI check sets out exactly when it is worth paying, our guide to stolen car checks covers the theft angle in depth, and our guide to spotting a rebuilt Cat S or Cat N write-off explains what those markers mean. When you have found the right car, our used car sales receipt and contract guide shows how to record the deal safely.

Frequently asked questions
Is checking a car on GOV.UK really free?
Yes. Check MOT history, MOT status, vehicle tax and the DVLA vehicle enquiry are all free and need only the registration number. There is no account to create and no charge at any point.
Can I check a car’s mileage history for free?
Yes. The free MOT history on GOV.UK shows the recorded mileage at every test back to 2005. Reading those figures in order is the best free way to spot a clocked car.
Does GOV.UK show outstanding finance or if a car is stolen?
No. The free government checks do not show outstanding finance, write-off category or stolen markers. Those require a paid history check, which draws on insurance and finance industry data GOV.UK does not hold.
What is the MOT fee and when does a car need one?
A car needs its first MOT at three years old, then one every year. The maximum test fee is £54.85, and cars over 40 years old are usually exempt.
