Your One-Stop EV Charging Solution

Ocunio Energy is the trading name of Nison Limited, an OZEV-approved EV charger installation company built on a simple observation: too many people invest thousands in an electric vehicle, then undermine that investment on day one.

We kept seeing the same pattern — someone buys a new EV, then reaches for a cheap granny charger because it seems like the easier option, without realising that slower charging puts greater strain on their home wiring and can cause long-term wear. Others simply don't know where to start, which charger suits their home, whether they qualify for a grant, or who to trust with the installation. That confusion is holding people back from embracing EVs with confidence.

This problem hasn't gone away. It's still what we see today, and it's exactly what led us to start Ocunio Energy — bringing the right charger, a proper certified installation, and full grant support into one straightforward service.

Today, based in Borehamwood, Hertfordshire, our certified engineers help homeowners, landlords, schools, and businesses across the UK make the switch properly: with a charger that protects their investment, and an installation done right the first time.
