EV Charger Installation
OZEV authorised charge point installer. Zappi, Ohme and Hypervolt chargers, positioned right, installed neatly, with a full walkthrough before we leave. Fitted installs start at £850.
Charge at home, on your terms.
A home charger means no more queuing at public charge points at whatever price they're set to that week. Wave Renewables is an OZEV authorised installer handling EV charger installation across Norfolk and Suffolk - Norwich, North Walsham and the surrounding area - fitting Zappi, Ohme and Hypervolt units. Zappi and Ohme can prioritise charging from your own solar panels when they're generating, so you're topping the car up on electricity you've already paid for. We position the unit where the cable actually reaches your car, run it in neatly, and show you how the app works before we leave.

Do you qualify for the grant?
From 1 April 2026 the EV chargepoint grant covers 75% of the cost, capped at £500 per socket. It's aimed at flat owners, renters and homes with only on-street parking - houses with a private driveway are no longer eligible. Answer three questions for a guide; we'll confirm it properly before you commit. Source: gov.uk.

1. Which describes your home?

2. What parking do you have for the charger?
-
3. Has an EV chargepoint grant already been claimed for this property?
A guide based on the current scheme rules, not a decision. Where you're eligible, we claim the grant on your behalf and it shows as a discount on your quote. The scheme runs to 31 March 2027.
Which charger?
All three are solid 7kW units. Zappi and Ohme add solar-priority charging; Hypervolt is a good all-round choice too. The right one usually comes down to how hands-on you want the app to be.
Zappi by myenergi
Three charging modes including a "solar only" mode that waits for surplus generation. Optional tethered or untethered. Add-on CT clamps for solar/battery integration. The enthusiast's choice - more settings to tune.
Ohme Home Pro
Leans on its app and your energy tariff - automatically charges when electricity is cheapest and greenest. Tethered cable, simple hardware. The set-and-forget choice, especially on a smart tariff.
Hypervolt
A neat, compact tethered unit with a simple app. Good build quality and a straightforward install.
Positioned right, wired correctly.
A home charger is a dedicated circuit from your consumer unit, not a plug-in accessory. On the site visit we check:
- Consumer unit - spare capacity and a spare way for the charger's dedicated circuit, or a small sub-board if not
- Earthing - chargers need specific earth-fault protection; Zappi and Ohme have PEN-fault detection built in, so no separate earth rod
- Cable route - the shortest tidy run from the board to where the car parks, clipped or trunked
- Load - optional load balancing so the charger backs off if the house draws heavily, avoiding a main-fuse upgrade
Most installs are done in a few hours, single visit. Pairing with battery storage lets you charge the car overnight from stored cheap-rate electricity.

Yes. Wave Renewables is an OZEV authorised Charge Point Installer covering Norfolk and Suffolk, so where you're eligible the grant is applied to your quote directly.
From 1 April 2026 it covers 75% of the cost of buying and installing a chargepoint, capped at £500 per socket, and runs to 31 March 2027. Source: gov.uk.
Flat owner-occupiers, renters (with landlord consent), residential landlords, and households with only on-street parking fitting a cross-pavement solution. Owner-occupiers of houses with a private driveway aren't eligible, and it's one claim per property. Use the checker above for a guide.
Zappi, Ohme and Hypervolt - all 7kW. Zappi and Ohme support solar-priority charging and load management. We'll talk through which suits how you'd use it. Fitted installs start at £850.
Yes. Both units can be set to charge the car preferentially from surplus solar generation rather than the grid, so daytime charging costs you nothing extra.
Usually not. The charger runs on its own circuit, and load balancing lets it back off when the house is drawing heavily - which avoids a main-fuse or supply upgrade in most homes. We check this on the site visit.
You need a dedicated space. A private drive, garage or allocated bay is simplest. Homes with only on-street parking can sometimes use a council cross-pavement channel, which also keeps grant eligibility. A loose cable trailed across a public pavement isn't permitted.
Most home EV charger installations are completed in a few hours, in a single visit.
