Data sources
Every section of a RegRadar report is attributed to its data provider, so you can see exactly where each fact comes from. Free checks use UK government APIs; premium reports add commercial data licensed through regulated partners.
RegRadar pulls vehicle identity, MOT and tax data directly from the DVLA Vehicle Enquiry Service and DVSA MOT history API. Premium finance, stolen, write-off, mileage-anomaly and previous-advert data is supplied by Experian and Cazana/Percayso through One Auto API.

How fresh is the data?
Free DVLA and DVSA checks are live at the moment of the request — there is no overnight cache on the free tier. Premium data (finance, stolen, write-off, adverts) reflects the most recent feed from each partner, typically refreshed daily. Where a provider cannot return a value (for example, very new imports), the corresponding section is shown as "no data" rather than a guess.
Independence
RegRadar is an independent vehicle history check service. RegRadar is not affiliated with HPI, DVLA, DVSA, Experian, Cazana, Percayso or One Auto API unless explicitly stated.
