Option 1: The Official Gov.uk Tool

The government provides a free MOT history checker. Here's how to use it:

1. Go to gov.uk/check-mot-history
2. Enter the car's registration number (number plate)
3. Click "Check MOT history"
4. View the full results

You'll see every MOT test the car has had since 2005. That includes passes, fails, and all advisory notes.

Option 2: CarOwl's Free MOT Check

CarOwl offers a free MOT and tax status check at carowl.co.uk/mot-check.

Enter the registration number and you'll instantly see:

What Does MOT History Show You?

An MOT history report contains valuable information about a car's past. Here's what you'll find:

Information	What It Tells You
Test dates	When each MOT was done
Pass/fail result	Whether the car passed or failed each test
Mileage	The recorded mileage at each test
Advisory notes	Minor issues that didn't cause a fail but need watching
Failure reasons	Exactly why a car failed (if it did)
Expiry date	When the current MOT runs out

Why Should You Check MOT History?

Checking MOT history is essential in several situations:

Buying a Used Car

Before buying any used car, always check its MOT history. It reveals:

• Mileage discrepancies: If the mileage went down between tests, the car may have been clocked
• Recurring problems: The same advisory appearing year after year suggests an ongoing issue
• How well it's been maintained: Lots of failures and advisories suggests poor care
• Hidden damage: Sudden changes in advisories might indicate accident repairs

For a full picture, combine the MOT check with a car history check to see write-off status, finance, and stolen records.

Checking Your Own Car

It's smart to review your own car's MOT history before the next test. Look at previous advisories. If the same issues keep appearing, get them fixed this time to avoid a fail.

Selling a Car

Buyers will check your car's MOT history. Review it first so you know what they'll see. Fix any recurring issues to make your car more attractive.

How to Spot Clocked Mileage

MOT history is one of the best tools for spotting mileage fraud. Here's what to look for:

• Mileage goes backwards: If the 2024 test shows less miles than the 2023 test, the odometer has been tampered with.
• Unrealistic jumps: Average UK mileage is 7,000-10,000 miles per year. Huge jumps or very low figures could indicate tampering.
• Gaps in history: Missing years might mean the car was off the road, or someone is hiding something.

Red flag: If mileage ever decreases between MOT tests, walk away from the sale. It's likely fraud.

Understanding MOT Advisories

Advisories are minor issues that didn't cause a fail but could become problems later. Common examples include:

• Tyres slightly worn: They passed but will need replacing soon
• Brake pads wearing: Still legal but getting thin
• Minor corrosion: Rust that hasn't affected structural parts yet
• Small windscreen chip: Not in the driver's view but worth monitoring

If you're buying a car with advisories, factor the repair costs into your offer. For more on this, see our guide to MOT advisories and failures.

What About Cars Before 2005?

Digital MOT records only go back to 2005. For older tests, you'll need to rely on:

• Paper MOT certificates (if the owner kept them)
• Service history records
• The V5C logbook showing registered keepers

For historic and classic vehicles, remember that cars over 40 years old may be MOT exempt.

Common Questions

Is checking MOT history really free?

Yes. The gov.uk tool is completely free with no registration required. CarOwl's basic check is also free.

Can I check any car's MOT history?

Yes. You can check any vehicle registered in the UK using its number plate. You don't need to own it.

How far back does MOT history go?

Digital records go back to 2005. Before that, you'll need paper records.

Why would mileage go down between MOTs?

It shouldn't. If it does, the odometer has been tampered with. This is illegal and a major red flag.

What's the difference between a fail and an advisory?

A fail means the car didn't meet safety standards and needs repairs before it's road legal. An advisory is a minor issue that passed this time but needs watching.

Final Thoughts

Checking MOT history takes about 30 seconds and costs nothing. There's no excuse not to do it.

Before buying any used car, check the MOT history for mileage fraud and recurring problems. Before your own MOT, review past advisories so you can fix them first.

Use the gov.uk MOT checker for full history, or CarOwl's free tool for a quick status check.

It could save you thousands.
