System Cost
1st-Year Energy Savings
Return on Investment
Charging at home or work is often cheaper than public charging stations — saving you 5p to 15p per kWh compared to public networks. When paired with solar, your savings increase by using clean, self-generated energy.
Combine your EV charger with Octopus Energy’s EV-friendly tariffs, like Octopus Go, which offers cheaper overnight electricity rates.
A home EV charger is up to 3 times faster than a standard 3-pin plug, ensuring your car is fully charged overnight.
Our EV chargers are compatible with all major electric vehicle brands and include smart features like scheduling and remote control.
We proudly recommend the SolaX Smart EV Charger G2 as our default solution for most installations, thanks to its:
Smart features & app control (Wi-Fi, OCPP, Modbus)
Solar integration for maximising self-use
Built-in safety protections (PEN fault, surge)
Tethered and untethered options (7kW–22kW)
Sleek design and IP65 rating for all-weather use
Prefer another brand? No problem — we install a wide range of EV chargers, including MyEnergi Zappi, Wallbox, PodPoint, Tesla, and more.
