Zaptec, Easee and Octopus Charge become the first devices to carry the Mercury mark for smarter home energy
London, 22nd June 2026: The Mercury Consortium has certified its first EV chargers, launching a new consumer trust mark for home energy devices. Like Bluetooth for consumer electronics, the Mercury mark is designed to help people know that smart energy devices will work reliably with the systems around them.
The Zaptec Go 2, the Easee Charge platform and Octopus Charge are the first products to carry the Mercury certification mark. Together, the companies behind the first certified products have over a million devices installed across Europe, bringing Mercury certification from concept to real homes, driveways and streets.
For consumers, the Mercury mark is designed to become a simple signal: this device is ready for the next generation of smart energy services.
The shift is already underway. The IEA expects the global EV fleet, excluding two- and three-wheelers, to reach 250 million by 2030, four times the level at the end of 2024. Ofgem says more flexible electricity use could help unlock £30bn to £70bn in savings and lower bills by reducing the need for expensive new infrastructure. Mercury is designed to help the next wave of chargers, batteries, heat pumps and smart home devices work together, not just plug in.
Mercury certification solves a missing piece. Communication standards such as OCPP help connect devices. Mercury certifies how those devices behave once connected: whether they respond, report and perform in the way energy systems need.
“Consumers should not need to understand grid flexibility to know whether the device they buy is ready for the future,” said Devrim Celal, Co-Chair of the Mercury Consortium & Chief Flexibility and Marketing Officer at Kraken. “The Mercury mark is about making that trust simple. These first certified chargers prove that smart energy devices can be tested once, trusted by the market and used to unlock cheaper, cleaner energy for households.”
“The challenge is no longer connecting devices—it is ensuring they behave predictably at scale,” said Robert Chapman, Co‑Chair of the Mercury Consortium & EVP & Chief Commercial and Customer Officer at EPRI. “Mercury certification provides the foundation for flexible load to become a system resource, enabling utilities to integrate electrification more affordably and reliably while avoiding unnecessary infrastructure investment.”
The first certifications focus on EV chargers. Mercury is now expanding its certification work across other major home energy technologies, including batteries, electric vehicles, heating and cooling, with the goal of creating a common trust mark for the devices that will power the flexible home.
“Smart charging and energy flexibility shouldn’t be limited to a handful of providers or technologies. Mercury is helping democratise access by creating a common standard that allows charge point manufacturers and energy companies to work together, giving more drivers access to cheaper, smarter and more flexible charging. We’re proud to have been involved from the beginning and excited about what’s next” said Michael Braybrook, Managing Director, Zaptec UK.
“Smart, affordable and grid-optimised charging needs to feel effortless for consumers,” said Anthony Fernandez, CEO of Easee and Board Member of the Mercury Consortium. “That only happens when the technology behind it behaves predictably and can be trusted in real-world conditions. Mercury certification verifies that behaviour, and represents an important step towards a more seamless, interoperable energy system.”
“An EV charger is not just a plug on the wall. Done right, it is the link between a customer’s car, their home and a cleaner, cheaper grid,” said Alex Schoch, VP / Group Director, Flexibility & Electrification, Octopus Energy and Board Member of the Mercury Consortium. “Mercury certification helps make that link easier to trust, so customers can get the benefits of smart charging without needing to understand what is happening behind the scenes.”
The Mercury mark is intended to help consumers choose devices that will not be left behind, help manufacturers prove their products are grid-ready, and help utilities scale flexibility with confidence.
About Mercury Consortium
Founded by EPRI and Kraken Technologies, Mercury Consortium is now a vendor-neutral, non-profit initiative shaped by more than 30 organisations across manufacturers, utilities, technology companies and regulatory stakeholders.
Its mission is to help EV chargers, batteries, electric vehicles, heating and cooling systems, and other smart energy devices integrate reliably with energy systems and participate in flexibility markets. Today, too much integration happens one device, one brand and one utility at a time. That slows down innovation, adds cost and makes it harder for households to benefit from cheaper, greener energy.
Mercury focuses on device behaviour and performance, working alongside existing communication standards rather than replacing them.
