You’ve spotted a car you like. Before you message the seller, arrange a viewing or get your hopes up, there’s a quick job worth doing: a free car check using the registration number.
It takes seconds, costs nothing and can save you a wasted trip. Here are seven things you can find out for free.
1. Whether the car matches the advert
A free check confirms the make, model and colour registered to that number plate. If the advert shows a black car but the check says it’s registered as white, ask why. It might have been resprayed, or it might be using someone else’s plates.
2. The engine size and fuel type
Is it really the 2.0 diesel the seller claims, or the 1.4 petrol? The engine size and fuel type affect performance, running costs and value, so it’s worth confirming.
3. How old it really is
You’ll see the year of manufacture and the date of first registration. These can differ, especially for imported cars, and they matter for value and insurance.
4. Whether it has a valid MOT
A free check shows the MOT status and expiry date. Without a valid MOT, a car can’t legally be driven on the road, except to a pre-booked test or for repairs. If the MOT is about to run out, factor in the cost and risk of a fail.
5. Its MOT history
Many free checks, and the official GOV.UK service, show past MOT results, including advisories and the mileage at each test. It’s one of the most revealing free tools around. Learn how to read it in our MOT history checker guide.
6. Whether it’s taxed
You’ll see if the car is currently taxed and when it expires. Remember, vehicle tax doesn’t transfer to a new owner. You’ll need to tax it yourself before driving it away.
7. Its CO2 emissions
For many cars, CO2 emissions affect how much road tax you pay. A quick look can help you estimate running costs before you commit.
What a free car check can’t tell you
A free check is brilliant for spotting obvious problems, but it can’t see the private records that hide the most expensive ones:
- Outstanding finance
- Police stolen records
- Insurance write-offs
- Plate change history and number of keepers
These need a paid check. Our guide to the vehicle history check explains what a full report includes.
How to do a free car check by registration
- Find the registration in the advert or photos.
- Type it into the free check box on this page.
- Compare every detail with the advert.
- If something doesn’t match, ask the seller before going any further.
- If everything checks out, unlock the full check before paying any money.
A simple free-check routine
If you’re comparing several cars, run a free check on each one. Cross off any that don’t match their adverts or have worrying MOT histories. Then pay for a full check only on the car you’re ready to buy. It’s the smartest, cheapest way to shop. For more ways to keep costs down, see our guide to the cheapest HPI check.

The bottom line
A free car check by registration is the quickest win in used car buying. It confirms the basics, flags mismatches and helps you avoid time-wasters. Just remember it’s the first step, not the last. Before you pay, get the full picture.
Frequently asked questions
Can I check a car by registration for free?
Yes. A free car check shows the make, model, colour, engine size, fuel type, age, MOT status and tax status for any UK registration.
Does a free car check show the owner's details?
No. Registered keeper details are protected and aren't shown on car checks. You'll see the number of previous keepers on most paid checks.
Can a free check show if a car is stolen?
No. Police stolen records are only available on a paid vehicle history check.
What does it mean if the colour doesn't match the check?
The car may have been resprayed without updating the DVLA, or it could be using another car's plates. Ask the seller and check the V5C logbook.
