The Myenergi Zappi and Ohme Home Pro are two of the most popular smart EV chargers in the UK, but they serve different needs. The Zappi is the go-to choice for households with solar panels, while the Ohme Home Pro is built around smart tariff integration to minimise your electricity costs. This guide compares both chargers across price, features, solar capability, and installation to help you choose the right one for your home.

Price Comparison
The Ohme Home Pro is significantly cheaper than the Zappi, both as a unit and fully installed. If budget is your primary concern, Ohme offers the lower barrier to entry while still delivering smart charging functionality.
The Zappi 2.1 costs between £779 and £865 for the unit alone, depending on whether you choose tethered or untethered and 7kW or 22kW. Add £300-£600 for standard installation, and the total lands between £1,100 and £1,500. The built-in PEN fault detection saves around £100-£200 on earth rod installation, which partially offsets the higher unit cost.
The Ohme Home Pro starts at £450 inc VAT for the unit (5m cable). Ohme bundles standard installation into a £999 package through approved installers. Even with the 8m cable upgrade at £629.50, the installed cost remains competitive.
Both chargers are OZEV-approved. If you are a renter, flat owner, or landlord, you may qualify for up to £500 off the installation cost through the EV Chargepoint Grant. Standard homeowners with driveways are not eligible.
Winner: Ohme. Up to £500 cheaper installed, with a bundled installation package that simplifies pricing.
Smart Features and Tariff Integration
Both chargers support smart tariff scheduling, but the Ohme Home Pro is the stronger option if your goal is to minimise electricity costs through off-peak charging. Ohme is an official Octopus Energy partner and integrates directly with Intelligent Go, automatically scheduling your charge during the cheapest windows at around 7p/kWh.
The Ohme also supports Octopus Agile, Octopus Cosy, E.ON Next Drive (6.9p/kWh), and British Gas EV Power Plus. The built-in 4G SIM means the charger connects without your home Wi-Fi, though this relies on mobile signal strength. After three years, a connectivity fee of around £2/month may apply. The colour LCD screen lets you start, stop, and monitor charging without opening the app.
The Zappi supports Octopus Intelligent Go and Gridpay, plus boost scheduling for off-peak tariffs. It connects via built-in Wi-Fi and Ethernet, which is more reliable than mobile signal in rural areas. The myenergi app handles scheduling, energy monitoring, and remote control. However, the Zappi has fewer direct tariff API integrations than the Ohme.
Winner: Ohme. More tariff integrations, direct API connection with Octopus, and the LCD screen adds genuine daily convenience.
Solar PV Compatibility
If you have solar panels and want to charge your EV with free electricity, the Zappi is the clear winner. Its ECO+ mode charges exclusively from surplus solar generation, never drawing from the grid. The standard ECO mode prioritises solar but tops up from the grid when generation drops, maintaining a minimum charge rate.
The Zappi integrates with the wider myenergi ecosystem. The Harvi wireless CT clamp monitors your solar generation, the Eddi diverts surplus to your hot water immersion, and the Libbi battery stores excess energy. This whole-home energy management approach is unmatched by any competitor.
The Ohme Home Pro offers a Solar Boost mode that diverts surplus solar to EV charging, but it is not as sophisticated as the Zappi. Solar Boost requires a post-January 2023 solar installation and does not offer the same granular control over grid import. For homes where maximising solar self-consumption is the priority, the Zappi delivers noticeably better results.
Winner: Zappi. ECO+ mode is the best solar divert feature on any UK home charger. The myenergi ecosystem adds further value for solar households.
Installation
Installation complexity is similar for both chargers, but the process and pricing differ. Both include built-in PEN fault detection, eliminating the need for a separate earth rod and keeping costs lower on TN-C-S (PME) electrical supplies.
Ohme bundles standard installation into its £999 price, which simplifies budgeting. You book through an Ohme-approved installer, and the price covers a straightforward setup with the consumer unit close to the charger location. Complex installations (long cable runs, distribution board upgrades) cost extra.
The Zappi is sold as a unit only, so you source your own OZEV-approved installer. Labour typically runs £300-£600 depending on complexity. This gives you more flexibility to shop around on installation price, but it also means more legwork. Both chargers comply with UK Smart Charge Point Regulations and are OZEV-approved for the EV Chargepoint Grant.
Winner: Ohme. Bundled installation is simpler and typically cheaper overall.
Warranty and Customer Service
Both chargers come with a 3-year warranty covering product defects and manufacturing faults. This is below the 5-year warranty offered by some competitors like Pod Point, but it is the industry standard for this price bracket.
Customer service is where the two brands diverge. Ohme scores 4.7 out of 5 on Trustpilot from over 14,000 reviews, with 85% five-star ratings. Users praise the app, the installation experience, and responsive support.
Myenergi scores 4.1 out of 5 from 2,942 reviews. While 76% are five-star, 13% are one-star. Common complaints include slow customer support (reports of 8+ days without a reply), app reliability issues, and a phase detection bug on some 22kW units that requires a manual reset.
Winner: Ohme. Significantly higher customer satisfaction and a larger review base.
Design and Build Quality
The Zappi 2.1 is a larger, heavier unit available in black or white. It carries an IP65 weatherproofing rating, which exceeds the industry minimum of IP54 and makes it suitable for fully exposed outdoor mounting. It is designed and manufactured in the UK at myenergi’s Lincolnshire facility.
The Ohme Home Pro is noticeably more compact at 170 x 200 x 100mm and just 4kg. The built-in colour LCD screen is a standout design feature, giving you charge status, session cost, and scheduling information at a glance. The Ohme offers tethered connections only (5m or 8m cable), while the Zappi gives you the choice of tethered or an untethered Type 2 socket.
Winner: Draw. The Zappi is more robust and versatile (IP65, untethered option). The Ohme is sleeker and has the better user interface with its LCD screen.
Zappi and Ohme: Pros and Cons
Here is a summary of the key strengths and weaknesses of each charger, based on verified specs, pricing, and real customer feedback from Trustpilot.

Our Verdict: Which EV Charger Should You Buy?
The right charger depends on your home setup and what you want to optimise for. Neither is objectively better – they are designed for different use cases.
– Buy the Zappi if you have solar panels and want to maximise self-consumption, need a 22kW three-phase option, or plan to build a myenergi whole-home energy system – Buy the Ohme if you want the cheapest installed price, prioritise smart tariff savings (especially Octopus Intelligent Go), or value a simple plug-and-go experience with strong customer support – Either works if you just need a reliable, OZEV-approved smart charger with basic scheduling and PEN fault detection
For solar homes: The Myenergi Zappi is the standout choice. ECO+ mode is the most advanced solar divert feature available on a UK home charger, and the wider myenergi ecosystem (Eddi for hot water, Libbi for battery storage) lets you manage your entire home energy system from one app. The higher upfront cost pays for itself through reduced grid import over 2-3 years.
For smart tariff savings: The Ohme Home Pro is the better buy. Direct API integration with Octopus Intelligent Go means automated charging at 7p/kWh with zero manual scheduling. At £999 installed, it is also the more affordable option. The 4.7/5 Trustpilot score from over 14,000 reviews gives confidence in long-term reliability.
