I install Zappi, Ohme and Hypervolt chargers regularly — and the question I get more than any other is "which one should I get?" The answer depends on your setup and what you care about. Below is my honest take based on installing dozens of each.
MyEnergi Zappi (~£1,000–£1,200 fitted)
The premium choice. Made in the UK (Stoke-on-Trent), and the only charger on this list with proper solar diversion built in — meaning if you have or are planning solar panels, the Zappi can charge your car only with the surplus solar that would otherwise be exported. That's genuinely valuable if you're generating 3-5kW on a sunny day.
Strengths: solar integration is best in class, has a built-in load balancing CT clamp (which means no consumer unit upgrade in many homes), excellent app, and the 7-year warranty is long. Tethered or untethered, both versions are good.
Weaknesses: most expensive of the three, and the app — myenergi — has had stability issues in 2024-2025. Better in 2026 but not perfect. For a household with no solar, you're paying extra for features you won't use.
Get Zappi if: you have solar (or plan to add it), or you want the built-in load balancing to avoid a consumer-unit upgrade.
Ohme Home Pro (~£800–£950 fitted)
The smart-tariff specialist. Ohme integrates directly with Octopus Intelligent Go, OVO Charge Anytime, EDF, Bulb and most other UK off-peak tariffs. You set your departure time and target charge in the app, Ohme works out exactly when to charge to hit the cheapest rates.
Strengths: best app on the market by a clear margin, slickest integration with cheap-rate tariffs, regularly the cheapest of the three. Strong support team.
Weaknesses: no proper solar diversion (a basic "solar mode" exists but isn't in the same league as Zappi). Uses the EV's API to schedule rather than the local grid load — works brilliantly with Octopus IO, less well with manual scheduling.
Get Ohme if: you're on Octopus Intelligent Go or any time-of-use tariff and you don't have solar. This is what I recommend most often for the average customer.
Hypervolt (~£900–£1,050 fitted)
Mid-range UK option. Solid build quality, RGB lighting on the unit (more useful than it sounds — quick visual check from the kitchen window), Type 2 socket, decent app.
Strengths: aesthetically the nicest of the three (matters more than you'd think for a wall-mounted unit), good app, solid load balancing, native solar mode (not as advanced as Zappi but adequate).
Weaknesses: smaller install network, fewer 3rd-party tariff integrations than Ohme, occasional firmware update reliability issues that the manufacturer is good about resolving but can be annoying short-term.
Get Hypervolt if: aesthetics matter to you, you want a solid all-rounder, and you're not deep into either solar or smart tariffs.
What About Easee, EVEC, Wallbox?
Easee Home is excellent and I install it sometimes — strong for multi-charger setups (apartment blocks, businesses) but slightly more complex install. Worth considering if you're thinking ahead to a second car. EVEC is the budget option (~£700 fitted) and works fine but lacks the smart features. Wallbox Pulsar Plus has European support and good build but the UK install network is thinner.
My Default Recommendation
For a typical Pinner / Hemel customer asking "what should I get?" with no strong preferences, I recommend Ohme. The combination of price, app, and tariff integration is hard to beat. If you have or want solar, Zappi. If you care about looks and app polish, Hypervolt.
Whichever you pick, the install spec is the same: dedicated 32A circuit, Type B RCD or built-in 6mA DC sensing, proper earthing, and full NAPIT certification. I install all three to OZEV standards so the £500 grant (where you qualify) is claimed on your behalf.
