Instant results, no account needed

Type a plate, get answers. Pay only if you want the full deep-dive. No sign-up circus.

Real buyers

What people say

โ€œWas about to put a deposit on a Focus that looked mint. The free score flagged moderate risk, so I unlocked the full report and found two failed MOTs with advisories the seller never mentioned. Walked away. Best tenner I never spent on a lemon.โ€

Dan, Leeds

Used car buyer

โ€œBought my daughter her first car and wanted something boring and safe, not a project. Bad Drivers UK spelled out the mileage pattern and MOT story in minutes. Gave me the confidence to say yes to a Corsa, and I can sleep at night.โ€

Karen, Bristol

Parent buyer

โ€œAlmost pulled the trigger on a 'low mileage' diesel. The tool showed mileage jumps that did not add up with the MOT dates. Dealer got shirty when I asked questions. Dodged a bullet.โ€

FAQ

Is this actually official data?+

Yes. MOT history and core vehicle details use the same DVSA/DVLA ecosystem garages use. The paid report adds finance, stolen, write-off, mileage and plate checks from licensed register data. No guesswork from ads or photos.

Why is the basic check free and what does the Full Report include?+

The free check gives you a trust score and headline risk signal. The Full Report at ยฃ9.99 adds MOT history, mileage analysis, ULEZ, road tax, AI trust score, finance, stolen, write-off, previous listings, recalls, spec, valuation and a downloadable PDF.

Do I need an account?+

No. Enter a UK registration, get your result. We do not force you through a sign-up wall before you see anything useful.

Will the seller know I looked up their car?+

No. This is a lookup against registration and MOT records, not a message to the seller or a mark on their listing.

What if the plate has almost no MOT history?+

Newer imports or very fresh cars can look thin on tests. We still score what exists and tell you honestly when data is limited, so you are not sold a fairy tale.

What does a Bad Drivers UK vehicle check include?+

The free check gives you a trust score and risk signal. The Full Report at ยฃ9.99 covers MOT history, mileage analysis, ULEZ, road tax, AI trust score, finance, stolen, write-off, previous listings, keeper history, plate changes, vehicle valuation, performance spec, Euro NCAP rating, fuel economy, tyre specification, safety recalls, factory equipment list and a downloadable PDF.

How do I check if a car has outstanding finance?+

Our full report includes a finance check that tells you whether the car has any outstanding finance secured against it. If it does, the debt follows the car, not the previous owner, so this is one of the most important checks to run before buying.

How do I check if a car has been written off?+

Our report flags any car that has been recorded as a write-off by an insurer, including the category (S, N, B or A). A Category S or N car can still be legally sold but must be declared. Our check tells you exactly what you're dealing with.

What does a Category S or Category N write-off mean?+

Category S means the car suffered structural damage but has been repaired. Category N means non-structural damage. Both can be legally driven and sold, but they're worth significantly less than a clean car and may be harder to insure. Always check before you buy.

What do MOT failures mean when buying a used car?+

Repeated MOT failures can indicate underlying mechanical issues. Our AI trust score takes MOT history into account and flags any patterns that should concern a buyer, like recurring failures on the same item or a string of advisories.

How is Bad Drivers UK different from HPI Check?+

HPI Check charges significantly more for a similar report. Bad Drivers UK gives you the same core data (finance, write-off, MOT history, stolen) plus an AI-generated plain English summary and trust score, all for less. We also have 141,000 followers on Facebook so we know a thing or two about bad cars.

What should I check before buying a used car?+

At minimum you should check: MOT history, outstanding finance, write-off status, stolen status, mileage consistency, previous listings (price, mileage and photos every time it was advertised), number of previous keepers, and whether any manufacturer recalls are outstanding. Our Full Report covers all of these in one place for ยฃ9.99.

Is one check enough or should I check multiple cars?+

If you're seriously considering a car, one check is essential before you hand over any money. If you're shopping around and comparing multiple cars, run a check on each shortlisted vehicle. It could save you thousands.

What is AI reliability research?+

Every Full Report includes an AI-generated summary of known faults and common issues for your exact make, model, and engine. It searches owner forums and the motoring press to flag recurring problems: things like timing chain issues, EGR valve failures, or gearbox faults that are common on specific engines. It is not a prediction about the specific car, but it tells you what to watch out for and what questions to ask the seller.

Don't get stung. Check before you buy.
