EV charging inspection specialist EVCI Global has launched a new industry initiative inviting Charge Point Operators (CPOs) to submit recently deployed EV charging sites for independent accuracy testing.
The campaign, titled The EVCI Diamond Charge Challenge, offers operators the opportunity to have a newly launched site independently inspected at no cost as part of EVCI’s Diamond Standard Accreditation programme.
The initiative comes as the EV charging sector continues to scale rapidly across the UK and Europe, with growing focus on transparency, performance verification and consumer trust.
EVCI’s independent testing programme measures whether EV chargers are delivering the amount of energy they report to drivers, helping operators understand the real-world performance of their infrastructure.
While EV charging accuracy is rarely discussed publicly, testing carried out by EVCI has revealed that charger performance can vary across networks, sites and hardware manufacturers. In some cases chargers may deliver slightly more or less energy than the amount recorded during a charging session. For operators, this can have implications both for customer confidence and long-term network performance.
The Diamond Charge Challenge invites CPOs to submit sites that have been installed or launched within the last six months. Operators may submit multiple sites for consideration, although only one site per operator will be selected for the complimentary inspection offered as part of the campaign.
Sites that meet the accreditation criteria following inspection may achieve EVCI Diamond Standard Accreditation, providing independent verification of charging accuracy.
Accredited sites may also be featured as case studies demonstrating high-performing charging infrastructure. Where a site does not meet accreditation thresholds, results will be shared privately with the operator and treated as confidential.
EVCI CEO Craig Marsden said:
“Independent accuracy testing will play an increasingly important role in building long-term confidence in EV charging. Drivers deserve to know that the energy delivered matches what they are paying for, and operators deserve visibility into how their infrastructure is truly performing.
“The Diamond Charge Challenge is designed to open that conversation in a positive way, giving operators the opportunity to independently verify their newest sites and demonstrate transparency as the market continues to grow.”
The competition opens today (13 March 2026) and will run until 5pm (GMT) on 27 March 2026. Charge Point Operators can submit eligible sites via the EVCI website.
