To do a vehicle history check, you need the car's registration number. Enter it into a vehicle history check service, review the MOT history, insurance write-off record, stolen marker, outstanding finance, mileage and keeper details, then compare everything with the V5C logbook and the car itself. It takes a few minutes and can help you avoid buying a car with a hidden problem.
Here is the process step by step, so you know what to do and what the results actually mean.
Step 1: Get the details from the seller
Before you travel to see a car, ask the seller for the registration number, the make and model, and clear photos of the car. Ask for the VIN (vehicle identification number) too. If a seller is reluctant to share the registration, treat that as a warning sign.
Step 2: Start with the free checks
You can use the free GOV.UK services to look up a vehicle's basic details and MOT history using just the registration. These show:
- Whether the vehicle is taxed and when the tax is due
- Whether it has a valid MOT and when it expires
- Make, colour, fuel type and first registration details
- Past MOT results, including failures, advisories and recorded mileage
The MOT history is very useful. Look for repeated advisories on the same item, such as corrosion or worn suspension, as they may point to neglect. Please note that motorpeek.com is an independent site and is not a government service or affiliated with the DVLA or DVSA.
Step 3: Run a full vehicle history check
Free checks do not cover everything. A full history check normally looks at extra data that can affect value, safety and legality, including:
- Insurance write-off records (MIAFTR)
- Police National Computer (PNC) stolen marker
- Outstanding finance
- Mileage records and possible discrepancies
- Number of previous keepers
- Plate changes, colour changes, and import or export markers
This is the point where it helps to check the vehicle's registration on motorpeek.com, so you can see these records in one place before you view the car or hand over a deposit.
Step 4: Understand what the results mean
Insurance write-off categories
If an insurer has written a car off, it should be recorded on the Motor Insurance Anti-Fraud and Theft Register (MIAFTR). The categories are:
- Cat A: must be scrapped entirely
- Cat B: the body shell must be crushed, but some parts can be salvaged
- Cat S: structural damage, repairable
- Cat N: non-structural damage, repairable
Cat S and Cat N cars can legally return to the road once repaired, but they are often worth less and some insurers charge more or decline cover. Ask for repair evidence and have the car inspected independently.
Outstanding finance
If a car is bought on finance, the lender may still have a legal interest in it until the agreement is paid off. A finance marker means you could face problems if you buy it without the debt being settled. Do not buy until the seller can show the finance has been cleared.
Mileage and possible clocking
Compare the mileage on the dashboard with the readings recorded at each MOT. A reading that drops, or a sudden unexplained gap, is worth questioning. Mileage records can have gaps or errors, so use them as a prompt for questions rather than proof either way.
Stolen marker
A check against police data can show whether a vehicle has been reported stolen and not recovered. If a car shows a stolen marker, do not go ahead with the purchase and consider contacting the police.
Step 5: Match the paperwork to the car
Always see the V5C registration certificate in person. Check that:
- The VIN on the V5C matches the number stamped on the car and shown on the windscreen or body plate
- The registration, make, model and colour match what you are viewing
- The seller's name and address match the registered keeper details
- The number of keepers fits what the history check shows
Be cautious if the seller says the V5C is lost, is being updated, or the address does not match. Also ask for service records and compare them with the MOT history.
Step 6: Know the limits of a history check
A vehicle history check is a very useful part of your research, but it has limits. It relies on data being reported correctly, so not every problem will appear, and it does not tell you the mechanical condition of the car. It cannot guarantee that a vehicle is free from faults or past damage.
For a used car you are serious about, combine the history check with a thorough test drive and, ideally, an independent inspection by a qualified mechanic or a recognised motoring organisation.
A quick checklist
- Get the registration, VIN and photos from the seller
- Check MOT history and tax status for free
- Run a full check for write-off, stolen, finance and mileage data
- Inspect the V5C and match the VIN
- Test drive and arrange an inspection
Taking these steps in order helps you spot problems early, negotiate with better information, and walk away from a car that does not add up.
Frequently asked questions
What do I need to do a vehicle history check?
You only need the vehicle's registration number to start. For extra confidence, also get the VIN from the seller and look at the V5C logbook in person. The registration lets you look up MOT history, tax status and other records.
Is there a free way to check a car's history in the UK?
Yes, GOV.UK offers free tools to check a vehicle's tax and MOT status and view its MOT history, including past failures, advisories and mileage readings. These free checks do not usually cover write-off categories, outstanding finance or stolen markers, which need a full history check.
Can a vehicle history check guarantee a car is safe to buy?
No. A history check shows recorded data such as MOT results, write-off status, finance and mileage, but it cannot show the full mechanical condition or guarantee there are no faults. Use it alongside a test drive and an independent inspection before you buy.
