Vehicle History Check UK: What the DVLA Data Actually Tells You
A free registration plate check reveals MOT status, tax, engine size, fuel type, CO₂ emissions and more - straight from DVLA. Here's how to read it, what the red flags look like, and how to use it before any used car purchase.

What the check covers
The DVLA Vehicle Enquiry Service (VES) is the same data source used by the government's own vehicle check at gov.uk. AutoAlpha queries it directly and returns the following fields for any UK-registered vehicle:
- MOT status and expiry date - whether the car has a valid MOT and when it runs out
- Road tax (VED) status and due date - whether the car is taxed or SORN'd
- Make and registration year - confirmed make, not just what the seller claims
- Colour - the registered colour (may differ from current paint if resprayed)
- Engine size in cc - confirms the spec you're looking at
- Fuel type - petrol, diesel, hybrid, or electric as registered
- CO₂ emissions (g/km) - affects road tax band and lets you estimate real-world MPG
- Euro emissions category - relevant for ULEZ and Clean Air Zone compliance
How to read MOT status
A "Valid" MOT means the car passed its most recent test and the certificate hasn't expired. "Expired" means no valid MOT - it's illegal to drive on public roads (except to a pre-booked MOT test) and the car may have known failures pending. "No results" means the car may be exempt (new vehicles under 3 years old, historic vehicles) or the plate returned no data.
The expiry date matters as much as the status. A car with one month left on its MOT will need a new test before you've barely driven it. Factor that into your offer - an MOT typically costs £55 at a standard garage, and any failures add to that.
Tip: Cross-reference the MOT expiry with the free MOT history check at gov.uk/check-mot-history. Look for recurring advisories - brake discs flagged as advisory two years running suggests the seller has been deferring maintenance.
How to read tax status
"Taxed" means road tax is paid and current. "SORN" (Statutory Off Road Notification) means the car is declared off-road - it's not legally driveable and the seller must tax it before sale or hand over a SORN so you can do it. Tax follows the car, not the owner, but it's no longer transferable - you'll pay from scratch when you take ownership.
CO₂ and Euro status: why they matter
CO₂ emissions in g/km determine the road tax band for older vehicles and give you a rough guide to real-world fuel economy. Divide 235.21 by the CO₂ figure to get an approximate MPG estimate (e.g. a car with 130g/km CO₂ is around 55 MPG combined).
The Euro category (Euro 4, 5, 6 etc.) determines ULEZ and Clean Air Zone compliance. Euro 6 petrol and diesel cars pass London's ULEZ. Older Euro 4 or Euro 5 diesel cars don't - a £12.50/day charge applies in the ULEZ zone. Check this before buying if you're in or near London or another CAZ city.
What colour discrepancy means
If the registered colour doesn't match the car in front of you, the car has been resprayed without the DVLA being updated (common, and not necessarily sinister) or - more rarely - the plates have been swapped. A quick check of the plates' age markings against the car's registration year will reveal mismatched plates.
