Every MOT, from a number plate.

Vehicle Wizard turns a UK registration into its complete MOT history — every test, the mileage recorded, and each advisory and failure in the tester's own words. Straight from the DVSA, in the time it takes to type seven characters.

What you get

The full history

Pass or fail, expiry date, odometer at each test, and every defect listed by severity — dangerous and major first, advisories after.

It remembers the listing

Check a plate on an eBay or Autotrader page and it sticks to that page. Come back and the history is already on screen, one click to forget it.

Take the data with you

Download any vehicle's history as JSON or as a CSV that opens straight in a spreadsheet, one row per defect.

Sign in and go

Google sign-in, nothing to configure. No API keys to paste, no account to create, no settings to fill in.

Getting it

It is not on the Chrome Web Store yet, and sign-in is limited to invited Google accounts while it is in testing. If you have been given access:

  1. Load the extension

    Open chrome://extensions, turn on Developer mode, choose Load unpacked and pick the extension folder.

  2. Sign in with Google

    Click the Vehicle Wizard icon and press Sign in with Google. That is the whole setup.

  3. Type a plate

    Spaces and lower case are fine. The history appears in the popup.

Where the data comes from

Every lookup is served by the DVSA's official MOT History API. The credentials for it live on a Cloudflare Worker, never in your browser, and each vehicle is fetched at most once a day — look the same plate up again and you get the stored copy rather than another call to the DVSA.

Google sign-in is used only to know who you are. The extension reads the address of the page you have open solely to remember which plate you checked there, and only while the popup is open.

MOT data is published by the Driver and Vehicle Standards Agency. Vehicle Wizard is an independent tool and is not affiliated with or endorsed by the DVSA.
