Quick verdict: Hypervolt Home 3 Pro is easy to use and well-regarded for its app. But it lacks OCPP support, three-phase capability, and offers only a 3-year warranty. Simpson & Partners wins on every technical measure for long-term, future-proof charging — and via EcoHarmony's volume pricing, is highly competitive on cost.

📖 Plain English

Hypervolt is the charger equivalent of a well-designed household appliance — it works, the app is nice, and you barely have to think about it. That's genuinely appealing. But if you want your charger to work with any management platform, handle three-phase power, and still be under warranty when your kids start driving — Simpson & Partners is a significantly better investment.

Where Simpson & Partners Has the Edge

🔌

OCPP Open Protocol

Not locked to Hypervolt's proprietary ecosystem. Any OCPP backend can manage it — vital for commercial and multi-charger sites.

⚡

Three-Phase Capable

22kW on three-phase — Hypervolt is single-phase only.

🛡️

Longer Warranty

Up to 10 years on enclosure. Hypervolt offers 3 years — a major difference in long-term confidence.

🌐

Ethernet Option

Wired network connection for demanding or commercial installs where WiFi isn't reliable enough.

🏢

Commercial Capable

OCPP + billing integration makes Simpson & Partners viable for workplaces and fleet sites.

🎨

200+ Colours

Hypervolt's clean white design is smart but fixed. Simpson & Partners matches any home.

Where Hypervolt Home 3 Pro Has the Edge

Simplicity: Hypervolt is one of the easiest chargers to install and use — a great choice for straightforward domestic setups.
App experience: The Hypervolt app is polished and user-friendly, with clear scheduling and monitoring.
Lower upfront cost: Typically cheaper to purchase than Simpson & Partners — though total installed cost varies.
Solar integration: The Pro model includes solar (PV) boost mode via CT clamp.

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.
