Questions About EV Charging?

Technically, you can plug your car into a regular socket but it’s slow, inefficient, and not recommended long-term. A dedicated home EV charger like the Zappi is faster, safer, and smart enough to save you money with off-peak tariffs or solar integration.

Most installations take just one day. Our team at OHM Energy will handle everything from the wiring and setup, to making sure the charger is tested, safe, and ready to use. If additional works are needed (like a supply upgrade), we’ll explain everything up front.

Yes. That’s what makes Zappi a standout choice. It can prioritise your own solar generation, meaning you charge your car using sunshine instead of the grid. Cleaner, cheaper miles for your commute or school run.

Yes. When installed alongside solar panels, home EV chargers currently qualify for 0% VAT. The UK government currently offers grants through the EV Chargepoint Grant and the Workplace Charging Scheme. These can cover part of the installation cost, depending on whether it’s for a home, rental property, or business premises. Our team at OHM Energy will check your eligibility and guide you through the application process.

A 7kW charger (single-phase) is perfect for most homes, giving you around 30 miles of range per hour of charge. A 22kW charger (three-phase) is faster, but requires a three-phase supply and is often better suited to businesses or commercial setups.

Prices start from around £1,200 including VAT and standard installation. Costs vary depending on your supply and any extra work required. We’ll always provide a clear, no-obligation quote and advice on available grants and finance options so you know exactly what to expect.

Yes. Zappi chargers are universal and compatible with all major EV brands. Whether you drive a Tesla, Nissan Leaf, Kia EV6, or BMW i4, you’ll be able to plug in without fuss.

Zappi chargers come with smart app integration. That means you can monitor charging sessions, schedule charging overnight when tariffs are cheaper, or see exactly how much solar energy you’ve used – all from your phone.

Not much. They’re designed to be robust and low-maintenance. An occasional check-up by our engineers can keep your charger working at its best, but most systems will run reliably day after day with minimal upkeep.

Absolutely. We design and install scalable EV charging setups for businesses across Sussex, Surrey, and Kent – from a few chargers in the car park to full commercial charging hubs.
