Why it matters
An EV can look perfect and still hide a £15,000 problem.
Unlike petrol and diesel cars, the health of an electric or hybrid vehicle is hidden inside its battery. Mileage and service history only tell part of the story. A professional pre-purchase inspection protects you from the most costly mistakes in used-vehicle buying.
Battery replacement: £5,000–£20,000
The battery is the most expensive part of any EV or hybrid. A degraded pack can wipe out the value of the car overnight.
Range you can’t see
Dashboard range estimates can be reset or misleading. Only a proper SOH test reveals the real usable capacity.
Hidden charging faults
Faulty onboard chargers, damaged ports and slow DC charging are expensive and rarely obvious on a test drive.
Stored fault codes
High-voltage and inverter faults are often cleared before a sale. Our diagnostics read the history too.
Heavier vehicle wear
EVs are heavier — tyres, suspension and brakes (seized from regen use) wear differently and cost more.
Negotiating power
Our report gives you evidence. Buyers save an average of £3,100 by renegotiating or walking away.

SOH battery certificate
Know exactly how healthy the battery is — in writing.
State of Health (SOH) shows how much of its original capacity a battery still holds. A new battery is 100%. Every VoltCheck inspection includes a signed SOH certificate so you can buy with confidence — and prove the battery's condition when you sell.
- Read directly from the battery management system — not estimated from range
- Usable capacity in kWh compared to the original factory figure
- Cell balance, temperature and insulation results
- Unique certificate number with QR verification
- Ideal for negotiating price, insurance and resale

Camper vans & motorhomes
Two inspections in one: the van and the home inside it.
Electric and hybrid camper vans have two complex power systems — the high-voltage drive battery and the leisure electrics. Damp and poor conversions can cost thousands. Our Camper Van Inspection covers the base vehicle and every habitation system.
- Leisure battery health
- Solar & inverter output
- Damp & water systems
- Gas & appliances
- 230V hook-up safety
- Payload & conversion
