EV Charging in Cambridge
A home EV charger gives you a 7–8x faster charge than a standard 3-pin socket, is significantly cheaper per mile than public charging, and — with solar panels and a Zappi — can give you near-free motoring from your own roof. With EV registrations in Cambridgeshire growing 40%+ year-on-year, home charging is rapidly becoming essential.

The myenergi Zappi is uniquely designed to work with solar panels. It detects when your solar system is generating surplus electricity and uses it to charge your EV — electricity that would otherwise be exported to the grid at 12–15p/kWh. For Cambridge homeowners with a 4kW solar system, the Zappi can provide 800–1,500 kWh of free EV charging per year — worth £220–£420 at standard rates.
Installation Process
Free Survey
We visit your Cambridge property to assess the best cable route, consumer unit capacity, and location for the charger. This takes 20–30 minutes.
OZEV Grant Application
We apply for the £350 OZEV EV Chargepoint Grant on your behalf. We handle all the paperwork — you just need your V5C (vehicle registration document).
Installation Day
A qualified OZEV-registered electrician installs the charger in 3–5 hours. This includes fitting the charger, running the cable to the consumer unit, and configuring the app.
Handover
We walk you through the charger controls, app setup, and smart tariff recommendations. Your charger is registered for the OZEV grant and you receive all warranty documents.

Solar-Powered EV Charging in Cambridge
Pairing a solar panel system with your EV charger in Cambridge means driving on free electricity. With 1,040 kWh/m² annual solar irradiance, Cambridge generates enough surplus solar to cover 5,000–8,000 miles of EV driving per year at zero fuel cost. The myenergi Zappi is specifically designed to divert surplus solar power directly to your EV — no manual scheduling needed.
Battery + EV: Charge Overnight for 2p/mile
A home battery (Fox ESS 9.6kWh or Tesla Powerwall 3) paired with a smart tariff charges from the grid overnight at 7–15p/kWh, then feeds your EV charger during the day or early evening. This reduces EV charging costs to as little as 2p/mile — compared to 7p/mile at standard home rates or 15p/mile at public rapid chargers. For Cambridge households driving 10,000 miles/year, that is a saving of up to £500–£1,000 annually versus petrol at current prices.
Grants Available in Cambridge
CERP Warm Homes Local Grant (Cambridge City Council — consortium lead). All CB1–CB5 postcodes eligible for income-qualified households. Cambridge City Council also runs a separate free energy advice service.
EV chargers qualify for 0% VAT when installed at the same time as a solar panel system. We assess all available grants during your free survey.
Free EV Charging Potential in Cambridge
Cambridge receives 1,040+ kWh/m² — well above the UK average of ~900 kWh/m². The flat Fenland landscape north and east of the city means no horizon shading for most properties. This high solar yield means more surplus electricity available for EV charging via a Zappi — Cambridge homeowners with solar panels can expect 3,000-6,000 miles of free driving per year from solar alone.
