Most car check providers route your query through a chain of intermediaries: your browser, their server, a third-party API proxy, Experian, DVSA, and back again. Each hop adds latency. CarCostCheck uses direct API connections to DVSA and Experian AutoCheck, which eliminates the proxy layer and delivers responses in under a second of server processing time.
We also pre-cache common vehicle data (reliability scores by make and model, running cost estimates, insurance group averages) so the report can render as soon as the DVSA data comes back. The database lookups that generate the free report happen in parallel with the DVSA query, not after it. This is standard modern engineering, but it is surprisingly rare in the UK car check industry.
Here is the optimal way to check a car in person using CarCostCheck on your phone:
- Before you view the car, bookmark carcostcheck.co.uk on your phone's home screen for one-tap access.
- When you arrive to view the car, ask the seller for the reg plate. If they hesitate, that is already a red flag.
- Open CarCostCheck and type the reg. The free report appears in under 5 seconds.
- Scan the free report for red flags: low reliability score, MOT advisories, mileage anomalies, common faults.
- If the free report looks clean, pay £4.99 for the premium check. This adds stolen, finance, and write-off data in another 10 seconds.
- Make your decision on the spot.
Total time: 30 seconds from the seller handing you the reg to you having complete information. Total cost: £0 or £4.99 depending on whether you pull the premium report.
Even if you never pay for the premium check, the free CarCostCheck report alone is often enough to decide whether a car is worth serious consideration. Over 90% of buyers who end up walking away from a car make that decision based on the free report's reliability score, MOT history, or running cost estimates. The premium check is reserved for the small subset of cars that pass the free screening and are serious purchase candidates.
Every other UK car check provider gives you raw provenance data and charges for the privilege. CarCostCheck is the only service that bundles full Experian-sourced stolen, finance, and write-off checks with running costs, reliability scoring, and 12 free data points that nobody else offers at any price.
- 12 checks completely free, no sign-up. MOT history, mileage verification, reliability score, running costs, insurance group, common faults, DVSA recalls, ULEZ compliance, red flag alerts, fuel costs, road tax, and health score. Every other provider charges even for basic vehicle details.
- Premium history for £4.99. Stolen (PNC), outstanding finance, write-off (Cat A/B/N/S), previous keepers, VIN verification, plate and colour changes, scrapped marker. The exact same Experian database as HPI at £19.99.
- Valuation for £2.99. Real-time market value from 650,000+ live UK dealer listings. Days-to-sell, local vs national price, private vs dealer retail. Nobody else offers this at this price.
- Bundle for £6.99. Everything, all in one report. Still cheaper than a single HPI or AA check.
- No subscription trap, ever. HPI auto-enrols you in a £39/year subscription unless you opt out. CarCostCheck never does this. One-time payment, one report, done.
- Health score and AI analysis. A single 0-100 score summarising overall vehicle condition, based on MOT history, advisory patterns, and mileage consistency. No other provider offers this at any price.
- Sub-5-second results. Direct API connections to DVSA and Experian. Most competitors route through proxies and take 30-60 seconds.
Our premium data comes from Experian AutoCheck, the same source HPI, AA, and RAC use. You are paying less because we have lower overheads and run a modern tech stack, not because the data is inferior. Every check is instant, one-time, and tied to your reg plate forever.
