Quick answer

Check MOT History Before You View

To check MOT history before buying: enter the registration at MotR's free MOT History Checker. Look for consistent mileage progression (any drop = clocked), gaps in annual testing (off-road or illegal driving), repeated advisories (neglect), and failure patterns on safety-critical systems. This free 2-minute check reveals 30 years of maintenance history.

Step by step

Step-by-Step: Reading MOT History

Get the registration before you travel

Ask for it when you first contact the seller. Phrase it naturally: 'Can you send over the reg so I can do a quick MOT check before I travel?' A legitimate seller will send it immediately.

Run the free check at MotR

Enter the registration at MotR's MOT History Checker. You'll see the complete DVSA test record — every test date, result, mileage, advisory, and failure with reason codes. You can also run a combined MOT and tax check to confirm both current statuses before collecting the vehicle.

Check mileage at every single test

Create a simple progression in your head: is mileage consistently increasing year on year? Even a single decrease between tests is evidence of clocking. This is the most important thing to check.

Identify testing gaps

A car that wasn't tested for 18+ months raises questions. Was it SORN? Off-road? Being repaired after an accident? Ask the seller to account for every gap over 12 months.

Review each advisory carefully

List all advisories from the last 3–4 tests. Identify any repeats (neglect), and note the repair cost for each. These become your negotiating evidence — get quotes before viewing.

Analyse failure categories

Brakes, tyres, and suspension failures on safety-critical grounds are common. What matters is whether they were fixed. Multiple failures on different systems annually suggest a chronically troubled car.

Concerning patterns

MOT History Patterns That Should Concern You

Mileage drops between any consecutive tests — evidence of clocking

Brake failure appearing more than once in 3 years — suggests chronic underspending on maintenance

Corrosion advisory escalating in severity across tests — structural integrity risk

Testing at multiple different centres in the same year — shopping for a pass after failure

Consistent annual mileage drops dramatically in recent years — car being concealed

Advisory on tyres appearing multiple consecutive tests without resolution

Positive patterns

MOT History Patterns That Are Positive

Consistent annual testing at the same garage — stable ownership, regular maintenance

Mileage increasing progressively at every test — genuine use

Advisories addressed by next test — seller acted on tester notes

No failures in the last 3–4 tests — well-maintained vehicle

PRS (pass after rectification) entries — small repairs done at test centre, not a concern

Same test centre throughout — stable keeper history

Questions & answers

Frequently Asked Questions

How do I check a car's MOT history before buying?

Enter the vehicle's registration number at MotR's free MOT History Checker or at the DVSA's official service (check.mothistory.service.gov.uk). You'll see every test for up to 30 years — dates, pass/fail results, mileage at each test, advisories, and failures with reason codes.

What should I look for in MOT history when buying a used car?

Look for: (1) consistent mileage progression — any drop means clocking; (2) gaps in testing — 2+ years off-road with no explanation; (3) repeated advisories — the same item flagged multiple tests means neglect; (4) failure patterns — frequent failures on brakes, emissions, or structure.

How many MOT failures are too many?

There's no fixed number — context matters. A single failure that was fixed is normal. Three failures in the last 2 years, all on different systems, suggests a car that's constantly at the edge of roadworthiness. The nature of failures matters too: brake failures are more concerning than lighting failures.

What does an MOT advisory mean for a buyer?

An advisory is a wear item noted by the tester that didn't cause a failure. For buyers, each advisory represents a future repair cost. Treat every advisory as a negotiation lever — get repair quotes before purchasing and deduct those costs from your offer.

Can I check MOT history for any car?

Yes. MOT history for any registered UK vehicle is publicly accessible. You only need the registration number — no personal details or ownership verification.

What if a car has a gap in MOT history?

A gap means the vehicle wasn't MOT tested for that period. This could mean it was SORN (declared off-road), was driven illegally without MOT, or was being stored. Ask the seller to explain the specific period. A convincing explanation with supporting evidence (SORN confirmation, storage receipt) is reassuring.
