📖 Plain English

The Andersen A2 is a solid mid-market charger. But at its price point, you're getting less technical capability than Simpson & Partners — no OCPP, no three-phase, shorter warranty. Through EcoHarmony, Simpson & Partners delivers more for the money, with more design choices and better long-term protection.

Mid-Market Design vs All-Round Platform

The Andersen A2 is Andersen's more accessible entry point — a smart home charger with solid build quality and a cleaner price tag than the Quartz. It's a reasonable choice for homeowners who want the Andersen brand without the top-tier price.

However, the A2 still operates within Andersen's proprietary ecosystem, lacks OCPP, and tops out at 7.4kW single-phase. Simpson & Partners offers more technical headroom at a comparable or lower total installed cost via EcoHarmony.

EcoHarmony Price Advantage

EcoHarmony supplies Simpson & Partners chargers to large residential developments, commercial fleets, and installer networks across the UK. That volume-based buying power means you get highly competitive pricing — often below what you'd find at standard retail, with no compromise on warranty, support, or genuine product quality.

When you factor in Simpson & Partners' longer warranty, fewer required external components, and the reduced risk of future compatibility issues, the total cost of ownership is frequently lower than chargers with a cheaper sticker price.

Why this mattersAlways compare the full installed cost — charger, accessories, ongoing support, and likelihood of needing to replace the unit — not just the retail price of the charger alone.
