Car History Checks: What They Reveal and Why They're Essential

Before buying any used car, a history check can reveal hidden problems. Learn what they cover, which services to use, and how to interpret results.

A car might look perfect. The seller seems genuine. The price is right. But hidden beneath the surface could be outstanding finance, a write-off history, or clocked mileage. A history check reveals what the seller might not.

What Does a History Check Cover?

Outstanding Finance

The most critical check. If the previous owner took out finance and didn't settle it, the finance company still owns the car. They can legally repossess it – from you.

What it shows:

  • Whether finance is currently registered against the car
  • Which finance company holds the agreement
  • Approximate outstanding amount (sometimes)

Important: A clear check means no finance is registered NOW. It doesn't guarantee the seller will settle any finance before selling.

Write-Off Status

If a car has been written off by an insurance company, it's categorised:

  • Category A: Scrap only – should never be on the road
  • Category B: Body shell destroyed, parts can be salvaged
  • Category S: Structural damage but can be repaired (previously Cat C/D)
  • Category N: Non-structural damage, repairable (previously Cat D)

Write-off history significantly affects value and may indicate hidden problems from poor repairs.

Stolen Status

Checks against the Police National Computer to see if the car has been reported stolen.

Mileage Discrepancies

Cross-references recorded mileages from:

  • MOT tests
  • Service records
  • Previous history checks
  • Finance agreements

Identifies potential clocking where mileage has been fraudulently reduced.

Plate Changes

Shows if the registration number has been changed. Sometimes used to hide a car's history.

Previous Keepers

Number of registered owners. Many owners in a short time can indicate problems.

Import/Export Status

Whether the car was originally UK-registered or imported. Grey imports may have different specifications and can be harder to insure/service.

VIC (Vehicle Identity Check)

Whether the car has been through the DVLA's identity check process – often required for rebuilt write-offs.

Which Service Should You Use?

HPI Check

The original and most well-known. "HPI" has become a generic term like "Hoover."

  • Cost: Around £20-30 for full check
  • Data sources: Finance companies, insurers, DVLA, police
  • Guarantees: Offers financial guarantee if data is wrong

AA/RAC History Checks

  • Cost: £8-20
  • Reputation: Trusted brands
  • Integration: Can combine with inspections

AutoTrader

  • Cost: Free basic check; full check £8-15
  • Access: Convenient when browsing listings
  • Data: Similar sources to others

DVLA Services

Free checks available:

  • MOT history (gov.uk)
  • Tax status
  • First registration date
  • Engine size

Doesn't include finance or write-off data.

Specialist Services

  • Experian AutoCheck
  • mycarcheck.com
  • Total Car Check

How to Read the Results

Finance Check: Clear

Good news, but verify the seller will settle any recent finance. Checks only show registered agreements – a very recent loan might not appear immediately.

Finance Check: Finance Registered

Stop. Either:

  • Walk away
  • Require the seller to settle finance before completion
  • Use an escrow service that settles finance from sale proceeds

Never buy a car with outstanding finance and assume it'll be sorted later.

Write-Off: Cat S or N

The car has been in an accident serious enough for an insurance write-off but has been repaired.

Consider:

  • Quality of repair (get an inspection)
  • Impact on value (should be priced lower)
  • Insurance implications (some insurers won't cover)
  • Your comfort level with accident history

Write-Off: Cat A or B

This car should not be on the road. If you find one for sale, something is very wrong.

Mileage Discrepancy

Recorded mileages should always increase. If they decrease, either:

  • Clerical error (rare)
  • Mileage clocking (fraud)

Investigate before proceeding. Check service history stamps.

Plate Change

Not automatically suspicious (personalised plates are common), but verify the full history follows through the change.

Multiple Keepers

Five owners in three years? There may be a reason people keep selling it. Not a deal-breaker but worth investigating.

Stolen Marker

Do not proceed. Even if the seller seems genuine, buying a stolen car means losing it.

The Free vs Paid Question

Free Checks (MOT History, Tax Status)

Valuable but limited. They don't cover:

  • Finance
  • Write-off status
  • Stolen status
  • Mileage from non-MOT sources

Cover everything. For a £10,000 car, spending £20 on a proper check is obvious. Even for cheaper cars, it's worthwhile insurance.

When to Check

  • Before viewing: Don't waste time on problem cars
  • After viewing, before paying: Confirm everything is as described
  • For valuable cars: Consider multiple services to cross-reference

Limitations of History Checks

Recent Events May Not Appear

Finance registered yesterday might not show. Write-offs take time to process. Checks are snapshots, not guarantees.

Data Errors Exist

Occasionally, legitimate cars show false flags. If a check shows something unexpected, investigate before walking away automatically.

Private Finance

If someone took a personal loan (not car finance) to buy the car, this won't show. The car can still be repossessed for other debts.

Foreign History

Cars imported from abroad may have histories that don't appear in UK databases. Be especially cautious with imports.

Repairs and Quality

A check shows IF a car was written off. It doesn't show HOW WELL it was repaired. That requires physical inspection.

What to Do with the Information

All Clear

Great – proceed with physical inspection and purchase. The check doesn't replace viewing the car but gives confidence.

Finance Outstanding

Either walk away or ensure settlement before completion. Document everything if proceeding.

Write-Off History

Factor into your decision:

  • Is the price adjusted for the history?
  • Can you get an inspection to verify repair quality?
  • Are you comfortable with the residual risk?
  • Can you insure it?

Mileage Concerns

Get answers before proceeding. Service history with stamps can verify mileage. If the seller can't explain discrepancies, walk away.

Stolen Marker

Don't buy. Report to police. The seller may be innocent or may be a thief.

Protecting Yourself Further

Verify VIN

The VIN (Vehicle Identification Number) should match:

  • V5C document
  • Dashboard plate
  • Door frame plate
  • History check results

Mismatched VINs indicate cloning or fraud.

Check the V5C

Is it the new-style document (post-2019)? Does the keeper match the seller? Is the address believable?

Physical Inspection

History checks catch hidden problems. Physical inspections catch visible ones. Use both.

Pay Securely

Bank transfer is common but offers little protection. Credit card or finance provides Section 75 protection. Never pay cash without documentation.

If You've Already Bought

Finance Appears After Purchase

  • You may have rights against the seller for misrepresentation
  • Contact the finance company – they sometimes negotiate
  • Seek legal advice for significant amounts

Write-Off Not Disclosed

If a dealer sold you a written-off car without disclosure, this may breach the Consumer Rights Act (not "as described"). You may be able to reject.

Car Was Stolen

You'll lose the car (it belongs to the original owner), but:

  • Claim against the seller if traceable
  • Report to police
  • Check if your own insurance covers theft recovery

The Bottom Line

A history check costs £20-30 and takes five minutes. It can save you:

  • Thousands in lost money from finance repossession
  • The heartbreak of losing a stolen car
  • Buying a dangerous poorly-repaired write-off
  • Fraud from clocked mileage

There's no good reason to skip it. Run a check on every used car before you buy, regardless of how trustworthy the seller seems.
