Hardware that’s competent on a domestic driveway can fall apart at a 20-bay depot. The three EV chargers that dominate the UK landlord and fleet shortlist — Zappi, Andersen, Ohme — behave very differently when you push them. Here’s how each unit holds up at fleet scale, with the decision matrix and the cases for mixing them.
Myenergi Zappi — solar-tied, OCPP, strong load balancing
Zappi v2.1 is the unit of choice when a depot has, or plans to add, solar PV. The strengths at fleet scale:
- Solar diversion — surplus PV pushed into vehicle charging in real time.
- Eco+ mode that throttles grid draw to keep within site headroom.
- Native load balancing across Zappi arrays via the Hub controller.
- OCPP 1.6J compliance for multi-vendor depot scenarios.
- Strong UK service network — replacement units in 48 hours where the warranty’s live.
The trade-off: Zappi’s strongest features are tied to the Myenergi ecosystem. If the depot already runs another vendor’s controller or back-end, the integration story is more involved than it looks on the spec sheet.
Andersen A2 — architectural premium, cable management at scale
Andersen A2 is the unit chosen for visibility-sensitive sites — corporate HQs, conservation-area depots, customer-facing yards. The strengths:
- Cable concealed inside the unit body — no coiled cable management at a 20-bay depot.
- Choice of finishes for sites with planning constraints.
- Solid build quality and weatherproofing for outdoor depot bays.
- OCPP-compliant; integrates with most depot back-ends.
The trade-off: higher unit cost per socket, and the cable-concealment design means the cable length is fixed at install. For depots with variable bay layouts, the fixed length is a constraint.
Ohme Home Pro — tariff-integrated, fleet billing API
Ohme is the value pick at fleet scale, with strengths in tariff integration and back-end:
- Native Intelligent Octopus integration — automatic off-peak charging.
- API access for fleet-management platforms — telematics can push schedules.
- Built-in MID-approved metering — billing per-driver or per-vehicle is straightforward.
- OCPP-compliant; modern firmware update cadence.
- Competitive unit cost, especially in 5+ socket arrays.
The trade-off: Ohme’s strongest features assume the operator is on a smart tariff. Fixed-rate fleet electricity contracts negate part of the value.
Side-by-side decision matrix
| Factor | Zappi v2.1 | Andersen A2 | Ohme Home Pro |
|---|---|---|---|
| Solar diversion | Strong | None native | None native |
| Tariff integration | Eco modes | OCPP scheduling | Native Intelligent Octopus |
| Aesthetic finish | Functional | Premium / hidden cable | Functional / clean |
| Fleet billing | Via Hub | Via back-end | Native MID metering |
| Cost per socket (relative) | Middle | Highest | Lowest |
| OCPP compliance | 1.6J | Yes | Yes |
Hybrid arrays — when you’d mix
At fleet scale, mixing units in one depot is sometimes the right answer:
- Solar-PV depot: Zappi on PV-fed bays, Ohme on grid-only bays.
- Customer-facing yard with staff parking behind: Andersen on the customer-visible bays, Zappi or Ohme on the staff bays.
- Mixed fleet (vans + executive cars): Ohme for the high-utilisation van bays, Andersen for the lower-cycle executive bays.
The shared requirement across all three vendors is OCPP compliance, which lets a single back-end controller speak to every socket on the depot.

FAQ
Are all three chargers OZEV-approved?
Yes — Zappi v2.1, Andersen A2 and Ohme Home Pro are all on the OZEV-approved product list and are eligible for the relevant grants (residential landlord scheme, WCS 2 where applicable).
Can I mix Zappi, Andersen and Ohme in one depot?
Yes, provided the back-end controller speaks OCPP. All three are OCPP-compliant, so a depot-level controller can manage load balancing and scheduling across a mixed array.
Which charger is most future-ready for software updates?
All three support OTA firmware updates. Ohme’s tariff-integration and Zappi’s energy-management features see the most frequent updates; Andersen’s update cadence is slower but its hardware lifecycle is the longest.
