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.
