If you're buying, selling, or owning a used electric car in South Wales, you need an independent battery health check. Not the dealer's assessment. Not the dashboard. An independent, certified measurement from equipment that doesn't belong to the car or the person selling it.
Option 1: Main Dealer Check
Every EV dealer has diagnostic tools that read battery data. Cost: £100–£400. The problem: it reads the car's own BMS — the car marking its own homework. The dealer selling the car isn't going to hand you a report showing degradation. No independent verification, no QR code, no central database.
Option 2: Generic OBD Scan
Any mechanic with an OBD reader can pull battery data. Apps like LeafSpy and Scan My Tesla show estimates. Cost: free to £50. The problem: still the car's own data, no certificate, no standardised methodology, no credibility with a buyer.
Option 3: Aviloo Certified Independent Test
Aviloo is an Austrian battery diagnostics company used by dealers, insurers, and auction houses across Europe. The test measures the battery independently using professional equipment and produces a sealed certificate with SOH percentage, QR verification, and timestamp.
Cost through PAD in South Wales: £79 for EVs, £89 for PHEVs. Includes 12V load test and full OBD scan.
