A reg check (number-plate check) should turn a UK registration into a clear picture of the car: who made it, what condition the DVLA and DVSA think it is in, and whether anything serious is recorded against it.
What a useful reg check shows
A good reg check returns at least:
- DVLA identity: make, model, colour, fuel, engine, CO2, year.
- DVSA MOT history with mileages, advisories and failures.
- Tax and SORN status.
- A clear indication of what is not shown for free (finance, stolen, write-off).
What separates a strong reg check from a weak one
- Live data, not cached. DVLA and DVSA both expose APIs; a serious provider calls them in real time.
- No dark patterns. You should not have to enter an email, card or postcode to see free DVLA/DVSA data.
- Honest scope. Finance, stolen and write-off data is commercial and costs the provider money — anyone giving it away free is either bluffing or breaching their licence.
- Independence. The check should be honest about its sources and not pretend to be HPI, the DVLA or the DVSA.
Where RegRadar fits
RegRadar is designed for UK private buyers who want a fast, honest reg check first and a paid history report only when the car is worth the £9.99. It uses live DVLA and DVSA data, attributes every data point to its source on the report, and is not affiliated with HPI, DVLA, DVSA, Experian, One Auto API or Cazana/Percayso.
Bottom line
The best reg check is the one that returns the full live DVLA and DVSA picture for free and is honest about what only a paid report can confirm. Always cross-check the result with the V5C and a physical inspection.
