In a major milestone for charging accuracy and consumer confidence, Voqa, a new to market AC charger, has been awarded the VeriCharge Diamond Standard by EVCI, becoming one of the first charging providers to achieve the new independent accreditation.

The award follows precision testing at one of Voqa’s pilot sites at Glove Factory Studios, Holt, Wiltshire, where EVCI’s accredited metrological specialists assessed the performance of the Voqa One under real world operating conditions. The result: a clean pass across every output head, confirming that every unit tested delivered the exact energy drivers were billed for.

EVCI’s own testing across the UK market has found that one in three chargers currently falls outside accepted ±2% billing accuracy tolerances, highlighting a growing issue for both drivers and chargepoint operators. The VeriCharge Diamond Standard was created to address exactly that challenge, providing an independent benchmark for billing accuracy and technical accountability.

Unlike conventional pass marks, the Diamond Standard is uncompromising. Every charging head must pass against a ±0.1% reference meter, with no averaging and no margin for failure.

For Voqa, the accreditation reinforces a core promise: charging should be simple, seamless, and trustworthy.

“We couldn’t be happier that the Voqa One sailed through EVCI’s testing. EV drivers have a simple expectation: that the energy they pay for is the energy that reaches their battery. Independent certification is what turns that expectation into a fact. It’s the foundation of trust between a driver, a venue, and a charger. And now we have it.”  - Becky Lalanne, Managing Director, Voqa

Voqa’s wider pilot data supports that story. Across its early deployment sites, the company reports a 99% successful charge rate and 100% charger availability, positioning the business strongly as it moves from pilot phase into wider commercial rollout.

The VeriCharge Diamond Standard will now feature across Voqa’s accredited locations and commercial materials, giving site hosts and drivers immediate reassurance that charging performance has been independently verified.

Craig Marsden, CEO of EVCI, said the results were among the strongest the organisation has seen to date.

“The accuracy results recorded at the Holt site were exceptional, and exactly the kind of performance the VeriCharge Diamond Standard was created to recognise. I was equally impressed by the thoughtful design of the tethered Voqa One chargers - they combine technical precision with a genuinely user-friendly experience that stands out in today’s EV charging market.” - Craig Marsden, CEO, EVCI

For Voqa, a business built on the belief that commercial EV charging should be effortless and genuinely trustworthy, the VeriCharge Diamond Standard adds a further layer of independent credibility at a pivotal moment. As the company scales from pilot to commercial rollout, the accreditation will be displayed at all VeriCharge compliant sites and featured prominently in materials for channel partners and prospective site hosts.

Voqa has committed to annual re-testing of its network to maintain the accreditation as its fleet grows, and has said it hopes billing accuracy will eventually be embedded within UKCA and EU product certifications as a standard compliance requirement.

As EV infrastructure matures, independent verification is becoming more than a differentiator. It is becoming an expectation.

And if this announcement is any indication, the era of trust by design has officially arrived.

What is the VERICHARGE Diamond Standard?

The VERICHARGE Diamond Standard is EVCI’s highest independent accreditation for EV charging accuracy, created to verify that EV drivers receive exactly the energy they are billed for.

Unlike standard product certification, VERICHARGE focuses on real-world metrological performance, testing every charger output against a ±0.1% reference meter under live operating conditions. To achieve Diamond status, every output head must pass. There are no averages, allowances, or exceptions.

The standard was developed in response to growing concerns around EV charging billing transparency, following EVCI’s findings that one in three chargers tested in the UK falls outside accepted ±2% billing tolerances.

Why EV charging billing accuracy matters

Trust is fundamental to the EV driver experience. When drivers pay for charging, they expect every kilowatt-hour billed to be delivered to their vehicle – just as they would expect a petrol pump to dispense exactly what appears on the meter.

Yet billing accuracy has remained one of the least visible challenges in EV infrastructure.

As public charging networks expand, independent verification is becoming increasingly important for consumer confidence, regulatory readiness, and operator accountability. Accurate charging protects drivers, strengthens brand trust, and helps operators demonstrate transparency in an increasingly competitive market.

Standards like VeriCharge help move the industry from assumption to evidence.

How Voqa passed EVCI’s independent charger testing

Voqa submitted its Glove Factory Studios pilot site in Holt, Wiltshire, as part of EVCI’s Diamond Charge Challenge, inviting newly launched charging sites to undergo independent accuracy verification.

During testing, EVCI’s accredited specialists assessed the Voqa One chargers under real-world conditions, measuring every output head against certified reference equipment.

The result was a full pass, confirming that each charger delivered the precise energy billed to the driver.

Combined with Voqa’s wider pilot performance metrics – including a 99% successful charge rate and 100% charger availability – the result demonstrates both technical precision and operational reliability, earning the network the VERICHARGE Diamond Standard.
