How to Check a Used Car Before Buying in the UK (2026 Guide)

Buying a used car without checking it first is one of the most expensive mistakes UK buyers make. The good news: a proper check takes less than 10 minutes and can save you thousands.

Here's the exact process — using official government data and AI analysis.


Why You Must Check Before You Buy

Every year, thousands of UK buyers discover after purchase that their car has:

  • Clocked mileage — the odometer has been wound back to hide high mileage
  • Outstanding finance — the finance company can legally repossess the car
  • Write-off history — the car was in a serious accident and may not be safe
  • Stolen status — the car may be seized by police

A pre-purchase check catches all of these. It costs £4.99 for a full report. The alternative can cost thousands.


Step 1: Free VRM Check (30 Seconds)

Start with a free VRM check. Enter the registration plate and verify:

  • Make, model, year, and colour match the listing
  • Tax and MOT status
  • Engine size and fuel type

If anything doesn't match, walk away immediately.

Step 2: MOT History Check (2 Minutes)

The MOT history is publicly available and reveals:

  • Mileage at every test — the single best way to spot clocked mileage
  • Failure reasons — patterns suggest persistent problems
  • Advisory items — upcoming repair costs you'll need to budget for

Look for mileage consistency. If the mileage goes backwards between any two tests, the car has been clocked.


Step 3: Full History Report (£4.99)

For any car you're seriously considering, get a full history report. This includes:

  • Outstanding finance check
  • Write-off category check (Cat A, B, S, N)
  • Stolen vehicle check
  • Number of previous owners
  • Import/export history
  • Full MOT history with AI analysis

Step 4: AI Listing Analysis

CarLook AI can analyse the full listing — price, mileage, spec, and history — and give it a CarLook Score out of 100. The score tells you whether the price is fair, whether the mileage is consistent, and what to negotiate on.

Step 5: Physical Inspection

Even with a clean history check, always inspect the car in person. Key things to check:

  • Bodywork — look for uneven panel gaps and paint mismatches (accident repair)
  • Tyres — check tread depth and wear pattern
  • Under the bonnet — look for oil leaks and signs of poor maintenance
  • Service history — verify stamps match the mileage
  • Test drive — listen for unusual noises, check brakes and warning lights

The Bottom Line

A proper check takes 10 minutes and costs £4.99 for a full report. It can save you thousands. There's no excuse to skip it.
