The UK's free MOT history checker is one of the most useful pieces of open government data available to car buyers, sellers and owners. Every test since 2005 is public — dates, mileage, pass/fail results, advisories and defect items — for any UK-registered vehicle. Used properly, it will save you from bad buys, spot mileage discrepancies before they cost you, and back up your own service history when you sell.

This guide walks through how to use it, how to read what it shows, and — importantly — what it doesn't tell you.

How to check any UK car's MOT history

Go to check-mot.service.gov.uk.

Enter the vehicle registration. That's it. No account, no fee, no waiting.

You'll immediately see:

  • Every MOT test from 2005 onward
  • The date of each test
  • Odometer reading on the day
  • Pass or fail result
  • All advisories issued
  • All defects that caused a failure
  • Test expiry date on passes
  • The current MOT status

For vehicles first registered before 2005, the earliest online record is 2005 regardless of the car's age. Anything before that lives on paper certificates, if they've survived.

What the record actually shows

Each test entry breaks down as follows.

Test date and result — the day the test was carried out and whether it passed, failed or was aborted. Aborted tests are unusual and usually mean the tester couldn't complete the inspection safely (missing wheel nut key, faulty brake pedal, etc.).

Mileage — the reading on the odometer on the day. This is the single most important field on the record and the one buyers scrutinise most. Mileage should progress steadily forward. Any dip, plateau or unexplained jump is a red flag — see the section on mileage discrepancies below.

Defects — items that caused a failure. Categorised as Dangerous (must not be driven), Major (fail), Minor (advisory-equivalent, doesn't fail) since the 2018 MOT rule changes.

Advisories — items still within legal limits but showing wear or degradation. Brake pads at 3mm, tyres at 3mm, minor corrosion on suspension components. Read these carefully — they tell you what's about to fail next time.

Test station — the DVSA-authorised centre that carried out the test. If you're rebuilding a service history, these test stations sometimes also did the servicing.

How to actually read an MOT history

Most buyers glance at pass/fail counts and move on. That's the wrong way to read the record.

Start at the bottom, with the oldest test, and work forward.

Look at the mileage progression. Plot it in your head or in a spreadsheet. Is it consistent, roughly matching the UK average of 6,000–8,000 miles a year? Are there long gaps where the car appears to have barely moved? Very low mileage for the age of the car isn't automatically suspicious, but it's worth understanding.

Watch for repeat advisories. The same advisory appearing on three consecutive MOTs — say, "corrosion to rear subframe, not excessive" — suggests an owner who has been kicking a can down the road. Eventually that becomes a Major and the car fails.

Note the seasonal pattern. A car that consistently MOTs in March every year and then has one test moved to November has almost certainly changed hands, been off the road, or had extended repair work.

Cross-reference with your own service history. If your paperwork says "cambelt changed at 68,932 miles" and the closest MOT records mileage at 71,000 the following month, the timeline holds. If your paperwork says cambelt at 68,932 and the MOT the same year records 45,000, something is wrong.

Spotting mileage discrepancies

The DVLA record is the buyer's single strongest tool against clocking (odometer tampering). Any of the following patterns should stop a sale until explained:

  • Backwards mileage — reading lower than a previous test. This is almost always clocking, occasionally a replacement dashboard cluster or private-import re-registration.
  • Flat mileage across multiple years — the car isn't being used, but the readings are suspiciously round.
  • Unexplained jumps of 30,000+ miles between consecutive tests — possibly a long commute or a change of use, but worth asking.
  • First recorded reading much lower than expected for the car's age — possible import, possible clocking before first UK MOT.

If you spot any of these before buying, walk away or demand a full explanation with supporting paperwork. If you spot them on your own car, sort out the explanation and paperwork before you list.

What the free tool doesn't tell you

The MOT history checker is powerful but incomplete. It does not show:

  • Service history. Not one entry. The DVLA holds no service records — those live with garages and manufacturer DSR systems.
  • Insurance claims or write-off status. For that, use a paid HPI check via CarCheck, HPI itself, or the AA / RAC equivalents.
  • Outstanding finance. Same — paid HPI-style checks only.
  • Number of previous keepers. Shown on the V5C logbook, not on the MOT record.
  • Mileage between MOTs. The record only shows mileage on test days. A car can be driven 40,000 miles between tests with no online record of it.
  • Advisories that were fixed. If the garage fixed a brake pad advisory the same day and re-tested, the advisory still shows on record forever. Doesn't mean it's still there.

For a complete used-car check, combine:

  1. DVLA MOT history (free) — for test record and mileage timeline
  2. DVLA vehicle enquiry (free, gov.uk) — for tax, MOT status, first registration date
  3. Paid HPI-style check (£15–£30) — for finance, write-off, theft, plate change
  4. Physical service history from the seller — for the day-to-day service picture
  5. A pre-purchase inspection from an independent mechanic (£150–£250) — for mechanical condition

Using MOT history to back up your own selling

When you're the seller, the MOT record is your friend. Download it, include it in your sale-ready pack, and reference it in your listing.

A line in the ad like "Full MOT history available on the DVLA website — mileage consistent, no repeated advisories" pre-empts the buyer's first check and signals confidence. Combined with your own service documentation, it turns a haggling conversation into a confirmation conversation.

This is why the AutoArchive sale-ready PDF includes MOT record data alongside service records — buyers want to see the two lined up.

The bottom line

The MOT history checker is free, comprehensive back to 2005, and the single fastest way to sanity-check any UK car — including your own. Learn to read it properly, combine it with the paid checks it doesn't cover, and it will make you a smarter buyer and a more credible seller.
