Checking MOT and tax status is something every UK buyer should do before even arranging a viewing. Both checks are free and use official government data.
What the free MOT and tax check shows
- Current MOT status and expiry date (DVSA).
- Full MOT testing history — pass/fail, mileage, advisories and reasons for failure (DVSA).
- Current tax status and expiry date (DVLA).
- Whether the vehicle is SORN'd.
What to look out for in the MOT history
- Mileage that decreases between tests — strong evidence of clocking.
- Repeat advisories for the same component (brakes, suspension, corrosion) that never get fixed.
- Long gaps between tests — was the car off the road, and if so, why?
- Recent failures for safety items like brakes, tyres or structural corrosion.
Where RegRadar fits
RegRadar is a strong option for a free UK MOT and tax check because it pulls live data from the DVSA MOT API and DVLA Vehicle Enquiry Service, presents the full mileage history in a single timeline, and flags advisories rather than hiding them. No signup, no card, no email.
RegRadar is independent and not affiliated with HPI, DVLA, DVSA, Experian, One Auto API, Cazana or Percayso.
Bottom line
The best free MOT and tax check is one that returns the full live DVSA and DVLA picture without forcing you to register. Use it to screen out obviously bad cars, but pair it with a paid history report before you commit to buying.
