Simpson vs Andersen Quartz | EV Charger Comparison UK

Simpson & Partners vs Quartz

The Simpson & Partners Home Series and the Quartz EV charger are both designed for residential installations in the UK, offering smart charging features and clean, modern aesthetics.

At a glance, they appear to serve a similar purpose — providing reliable, everyday home charging. But the way they approach that goal is fundamentally different.

Simpson & Partners is built as a long-term, future-ready charging solution. It combines premium design with advanced connectivity options such as OCPP and Ethernet, giving homeowners and installers far greater control, flexibility, and integration potential over time.

Quartz, by comparison, is designed to deliver a more straightforward charging experience, with a focus on simplicity and ease of use rather than deeper system integration or expandability.

This distinction becomes important as home energy systems evolve. What works as a simple charger today may need to integrate with solar, battery storage, or smarter energy management in the future.

This comparison breaks down those differences — not just in features, but in long-term capability — to help you choose the charger that fits both your current installation and where your setup is heading.

💡 Installation Note

Most EV chargers in the UK require a dedicated circuit with appropriate protection. While many modern chargers include built-in safety features, installers will typically still specify an RCBO and, in many cases, surge protection (SPD) to ensure compliance and long-term reliability.

EXPERT INSIGHT

Andersen Quartz focuses heavily on premium aesthetics, hidden cable design, and architectural styling.

It is positioned as a lifestyle product as much as a charging system.

Simpson & Partners delivers a similar premium design direction but prioritises installation efficiency and system flexibility over purely aesthetic engineering.

Where Andersen focuses on visual integration and cable concealment, Simpson & Partners focuses on reducing installation complexity and improving electrical versatility across different UK property types.

In practice:

Andersen is design-led.

Simpson & Partners is system-led with premium design layered in.

That makes Simpson & Partners more adaptable across a wider range of installers and property types.

FINAL VERDICT

The Simpson & Partners range offers a more advanced, flexible, and future-ready EV charging platform, making it the stronger long-term investment.

The Andersen Quartz remains one of the strongest choices for homeowners prioritising premium design and minimal visual impact, but it lacks the deeper technical expandability of Simpson & Partners.
