Frequently Asked Questions

Common questions, answered

Can I claim the OZEV grant through Osmo Electrical?

Yes. As an OZEV-approved installer, eligible customers — including flat-dwellers, rental tenants, and businesses applying through the Workplace Charging Scheme — can have the grant discount applied directly to their quote. We handle the paperwork end-to-end.

How long does an installation typically take?

Most standard home EV charger installs are done in one day. Jobs that also need a consumer unit upgrade, a long cable run, a three-phase supply or several chargers on a commercial site take longer — we confirm exact timings after the site survey, before you book.

Do you work on commercial and workplace sites?

Yes. Workplace EV charging, three-phase installations, EICRs, reactive callouts for offices and light industrial sites, and full compliance reporting.

Will I receive a quote before any work starts?

Always. After an initial chat and site survey, you'll receive a clear, itemised quote — no hidden extras, no surprise charges. Nothing proceeds until you've reviewed and approved it.

Can I integrate an EV charger with a home battery storage system?

Yes. We can set up smart charging schedules that work alongside a home battery storage system, helping you charge from stored energy or off-peak tariffs rather than drawing from the grid at peak rates.
