What earthing and PME protection do I need for a Simpson & Partners install?

Like all EV chargers on a PME (TN-C-S) earthing system, appropriate PME protection is required under BS 7671 Section 722. Options include an earth rod where ground conditions allow, or an RDC-DD protection device. EcoHarmony supplies both and can bundle protection with your charger order.

How does the Simpson & Partners right-to-repair warranty work in practice?

Simpson & Partners commits to making spare parts available at cost price for all units, including those out of warranty. A transparent published parts price list allows installers to quote repair costs accurately, reducing full replacement call-backs.

Why Simpson & Partners?

The Charger Your Customers Will Thank You For

Most EV chargers are sealed, disposable units. Simpson & Partners is built to last — and that's a powerful story to sell to your customers.

🔧

Right to Repair — A Real Sales Advantage

Modular design means individual components can be replaced rather than the entire unit. Spare parts available at cost price, even out of warranty — a unique selling point your customers will remember.

📡

Smart Tariff & Octopus Integration

Native Octopus Energy and Kraken platform integration. Automatic off-peak scheduling with no manual setup. Customers on smart tariffs will notice the savings from day one.

🔋

V2G Ready — Future-Proof for Your Customers

Vehicle-to-grid capability can be unlocked later without replacing the unit. Protects your customer's investment as EV technology evolves.

📶

Ethernet + Wireless Energy Management

Ethernet connectivity for reliable smart tariff operation. Wireless load management for tricky installs where cable runs are difficult — a big advantage over most competitors.

🛡️

5-Year Warranty — Fewer Call-Backs

Comprehensive manufacturer warranty with genuine repair-first support. Less time on warranty call-backs, more time on new installs.

⬆️
