Statutory vehicle testing in Northern Ireland is run by the Driver & Vehicle Agency (DVA), not DVSA in Great Britain. Car Buyer Check is built around the DVSA MOT History service for GB tests, plus DVLA vehicle data when that connection works for your lookup. A plate that looks Northern Irish does not automatically mean our MOT timeline is complete or that testing rules match England, Scotland, or Wales.
What our lookup actually does
When you enter a registration, we request the same government feeds used elsewhere in the app. If DVSA returns MOT tests, you see them in the timeline and pattern engine like any other plate. If MOT History is missing for that check, the report can fall back to a DVLA-only snapshot with an explicit limitation that defect history was not available — tax and MOT status are a point-in-time licensing view, not a full test record.
For registrations matching a three-letter, four-number pattern (for example DEZ1234), the engine may add an ni-format finding. That observation is only a format match. The interpretation states plainly that we do not treat the vehicle as confirmed Northern Ireland or Great Britain from the plate alone. You must confirm jurisdiction with the seller and paperwork.
Official MOT history in Northern Ireland
For vehicles tested under DVA in Northern Ireland, use the official online MOT history service on nidirect. Car Buyer Check does not replace that channel and may not show DVA test detail even when DVLA returns identity fields.
- Run our reg check when you want GB MOT History plus buyer-report patterns for whatever tests came back in the feed.
- Cross-check NI-registered cars on nidirect before you rely on a quiet or partial timeline here.
- Read limitations in the report when motHistory is empty — do not assume the car has never been tested.
Preview and buyer report
The free preview and buyer report only interpret tests present in the payload. Seller questions, map areas, and recurrence rules apply to those lines — they do not invent DVA results. If you need NI-specific test wording, obtain it from DVA first, then decide whether our GB-oriented patterns add anything for your purchase.
