Evidence built into the certificate
Each new certificate requires both vehicle and VIN proof before it can be issued.
Public sample - customer details sanitised
We carry out an in-person EV or hybrid battery health check and provide clear certificate evidence that helps buyers, sellers and owners understand battery condition with more confidence.



We physically attend and inspect the vehicle. The certificate connects the result to the actual car with inspection photographs, VIN evidence, mileage, test date and technician records - giving buyers something meaningful to verify.

The certificate now separates the dashboard range showing at today's charge from an illustrative estimate at 100%. A buyer will not mistake 20 miles at 10% charge for the vehicle's maximum range.
A certificate helps answer that question before a buyer hesitates, a seller loses trust, or an owner ignores early warning signs.
Clear, professional battery health evidence for handover, retail listings and buyer reassurance.
We attend the vehicle and carry out the check properly, instead of relying on vague remote claims.
