A car history check is one of the smartest things you can do before buying a used car in the UK. It reveals key details about a vehicle’s past, like MOT history, road tax status, and mileage records, so you can avoid unpleasant surprises.
While full reports go deeper with checks for finance, write-offs, and theft, many buyers start with a free car history check to help them compare listings and narrow down their options.
In this guide, we’ll show you what a free car check report includes, where the data comes from, and how it helps you spot early red flags before investing in a full report.
Why a free car history check matters before you buy
When you’re browsing used cars, it’s easy to get drawn in by clean photos or a tempting price.
But what’s underneath the surface often tells a different story, and that’s where a free car history check comes in.
It gives you key facts about a vehicle’s past without spending a penny.
Think of it as your first filter, helping you rule out risky options and focus on cars that are worth your time and money.
Here’s how a free car check helps you make smarter decisions:
1. Quickly spot initial red flags
Check if the MOT is valid, the car is taxed, and the mileage looks consistent. If anything doesn’t add up, you can walk away early.
2. Shortlist cars worth viewing
When comparing multiple listings, a free report helps you narrow them down based on MOT history, mileage usage, and roadworthiness.
3. Verify key vehicle details
You can confirm the first registration date, age, last V5C issue, and whether the tax is current, all of which matter for ownership transfer and legal use.
4. Plan ahead for costs
CO2 emissions and MOT advisories can give you a sense of future running or repair costs, especially for older vehicles.
5. Decide if you need a full history report
If something in the free report raises a question like a recent V5C issue date, a mismatch in MOT mileage history, or a sudden drop in recorded mileage, that’s your signal to upgrade and check for hidden risks like finance, write-offs, or theft.
What do you get in a free car check?
The free version of a car history check gives you a quick overview of a used vehicle’s background, all without paying anything.
It’s not as detailed as a full report, but it’s a smart way to spot early issues and decide whether a car is worth looking into further.
Here’s what you’ll see in your free report, along with what each part tells you:
Tax and MOT Status
Shows whether the car has a valid MOT & Tax and when it’s due, whether any advisories were raised, the number of MOTs it has had in the past, and when the road tax will expire. This helps you check if the vehicle is legally roadworthy.
MOT History
Lists each MOT test result, including dates, mileage at the time of test, pass/fail status, and any advisory or failure notices. It can help you spot past issues like suspension problems or other recurring faults.
Each MOT entry tells a part of the car’s story. Check our MOT History guide to learn how to read past results, understand advisory notes, and pick up on patterns, including mileage gaps that might signal trouble.
Mileage Checks
Displays the current mileage, average yearly mileage, mileage recorded in the last year, and whether any issues were detected (e.g., possible rollback).
Also gives a status like “Low” or “Normal” to help assess wear and tear.
Mileage History
Provides a breakdown of mileage recorded at each MOT test over the years, shown both as a table and a graph. It helps you understand the vehicle’s long-term usage pattern.
Vehicle Registration
Includes the car’s age, date of first registration, year of manufacture, last V5C issue date, and how long ago it was issued. This can help you check for recent ownership or registration changes.

CO2 Emission Figures
Shows the vehicle’s CO2 emissions in g/km and the corresponding VED (Vehicle Excise Duty) band. This impacts how much road tax you’ll pay and is useful for checking environmental impact or fuel economy.
Car Specs
Displays general specification headers such as make & model, engine type, body shape, current color, fuel type details upto export maker & emission bands.
While this guide gives you a quick view of what’s included in the free report, our Car Spec check guide explains each part in detail and how it can help you choose the right car with more confidence.
ULEZ Compliance
Lets you check if the car meets the Ultra Low Emission Zone (ULEZ) standards for driving in London without daily charges, based on CO2 and Euro emissions data.

Where are these free report data sourced from?
The information you see in a free report is pulled directly from trusted UK government and official sources.
This means you’re not relying on guesswork or third-party sellers, you’re getting accurate up-to-date data that reflects the real history of the vehicle.
Here’s where each section of the report comes from:
1. DVLA (Driver and Vehicle Licensing Agency):
Supplies information for sections like Vehicle Registration, Tax and MOT Status, CO2 Emission Figures and Car Specs.
2. DVSA (Driver and Vehicle Standards Agency):
Provides the data used in MOT History, Mileage Checks, and Mileage History, helping you understand how the car has been used and maintained.
3. TfL (Transport for London):
ULEZ compliance is based on emissions data sourced from the DVLA and checked against TfL’s latest clean air zone rules.
4. Safety Recalls data:
Recall information is provided by the vehicle manufacturer and shown via the DVLA. If you believe recall info is incorrect, contact the brand’s local dealership.
What’s missing in a free report?
A free car check is a great first step, but as you know it doesn’t show everything.
Crucial details like whether the car has outstanding finance, was written off by an insurer, or has been reported stolen are only available in a full car history check.
These checks can reveal serious issues that don’t show up in a basic report, and could cost you later if missed.

When should you upgrade to a full vehicle check?
By now, you know what a free report covers and what it doesn’t. So when does it make sense to go further?
If you’re unsure about a car’s background or feel that something doesn’t add up, a full history report helps you dig deeper and avoid unexpected risks.
It’s especially useful in situations like these:
1. You’re buying from a private seller:
Unlike dealers, private sellers aren’t legally required to disclose everything. A full check helps you uncover risks the seller might not mention, or may not even know.
2. The free report raises questions:
If you notice things like a very recent V5C update, mileage inconsistencies, or gaps in MOT history, a full report can help you dig deeper and find out what’s going on.
3. The car is high value or newer:
If you’re considering a newer used car or one with a higher price tag, it’s even more important to be sure about its past. These cars might look nearly new, but that doesn’t mean they’re risk-free.
A full vehicle check helps you make sure you’re not overpaying for a car that’s been written off, has hidden finance, or other issues that sellers might not disclose.
4. You’re buying for long-term use or a family member
If the car’s meant for daily use or will be driven by someone you care about, reliability and safety naturally come first.
A full check helps you feel sure there’s nothing hidden in its past that could lead to problems later, giving you extra peace of mind before handing over the keys.
Making smarter car choices with the right Info
If you’re exploring used cars, a free history check can be a smart way to narrow things down. It won’t tell you everything, but it’s enough to spot obvious risks, check official records, and make early comparisons without wasting time.
From there, you’ll know which cars are worth looking at more closely, and which ones you can rule out straight away.
And if anything feels off or incomplete, that’s when it’s worth digging deeper with a full car check.
Whether you’re browsing casually or planning to buy soon, checking a car’s background is always worth a minute. It’s quick, free, and could save you from choosing the wrong one.
