Know exactly what
your EV battery is
worth.
A used EV is only as good as its battery. Before you buy, sell, or insure — get a certified State of Health report from Voltest. We come to you, test in 30 minutes, and give you data you can act on.
Four steps from booking to certificate
No garage visits. No waiting. We come to your home, workplace, or anywhere convenient across Sussex and Surrey.

What you get that you can't get elsewhere
Most people have no idea what condition their EV battery is actually in. Voltest changes that.
Certified Report, Not Just a Reading
You receive a formal Voltest certificate showing State of Health percentage, capacity data, cell balance, and a graded assessment — not a raw number with no context.
We Come to You
No need to book a garage, take time off, or drive somewhere. Our technician comes to your home, workplace, or wherever suits you across Sussex and Surrey.
200+ EV Models Covered
From Nissan Leaf and Tesla Model 3 to BMW iX and Volkswagen ID.4. Check the full list — if it's on there, we can test it today.
Negotiating Power
A battery showing 78% SoH on a car advertised as excellent is leverage worth far more than the cost of the test. Buyers use it to negotiate; sellers use it to justify the price.
Peace of Mind Before You Buy
EV battery replacement costs £5,000–£15,000. A Voltest check costs from £60. It's the cheapest insurance you'll ever buy on a used EV purchase.
Same-Day Results
The test takes 30 minutes. Your certified digital report arrives the same day — fast enough to fit into any sale, purchase, or handover timeline.
Whether you're buying, selling, or managing a fleet
Used EV Buyers

A Voltest certificate proves your battery's condition and justifies your asking price.
Dealers & Traders
Add certified battery data to every EV in stock. Build trust, reduce returns, increase margin.
Fleet Operators
Track degradation across your EV fleet. Plan replacement cycles before they become operational problems.
Frequently asked
State of Health measures how much of your EV's original battery capacity remains. A new EV with a 40kWh battery at 80% SoH effectively has 32kWh — which directly reduces real-world range. Knowing the SoH tells you exactly what you're dealing with in practical, financial terms before you buy or sell.
The diagnostic test takes approximately 30 minutes. We connect to the vehicle via the OBD2 port, run a full battery diagnostic, and you receive your certified report the same day.
