Zappi v2.1 costs from £899 installed — but the real saving depends on your tariff
The Zappi v2.1 is one of the most talked-about home EV chargers in the UK, largely because of its solar integration. But the headline price tag of £899 for the unit alone does not tell the full story.
The Zappi v2.1 costs £899 for the unit and £1,100–£1,200 installed. Savings depend entirely on pairing it with a smart tariff like Octopus Intelligent Go or OVO Charge Anytime.
- Unit costs £899, installed price £1,100–£1,200 from MCS-registered electricians.

The charger unit costs roughly £899–£1,200 including installation, depending on your home setup and installer. Without a smart tariff, the charger itself saves nothing — the saving comes from pairing it with a time-of-use electricity tariff (e.g., Octopus Intelligent Go or OVO Charge Anytime).
Myenergi publishes an RRP of £899 for the 7.4 kW tethered unit (Myenergi website, 2026). Installed quotes from MCS-registered electricians typically range from £1,100 to £1,200 (MCS-certified installer quotes, 2026). Octopus Energy and OVO tariffs as of 2026 are listed on their respective websites.

Who qualifies for the Zappi v2.1 — eligibility and grant rules
The Zappi v2.1 is eligible for the Electric Vehicle Homecharge Scheme (EVHS) only if you own a qualifying EV and have off-street parking. EVHS provides up to £350 off installation costs, but the scheme is now limited to homeowners who have not previously claimed a grant for a charger at the same property (GOV.UK EVHS guidance, 2026).
You must use an OZEV-approved installer — check the OZEV-approved installer list on GOV.UK — and the installer handles the grant application. If you live in a flat or have no dedicated off-street parking, you are not eligible for EVHS. You may qualify for the On-Street Residential Chargepoint Scheme instead, which is led by your local authority (DESNZ grant eligibility criteria, 2026).
The Zappi v2.1 is a 7.4 kW smart charger that can use solar excess — here is how that works
The Zappi v2.1 is a Mode 3, 7.4 kW (single-phase) or 22 kW (three-phase) smart EV charger with built-in solar integration. It can charge using 100% solar surplus when paired with a solar PV system and the Myenergi hub (Harvi or Eddi).
“Solar excess” charging means the Zappi diverts only the power your solar panels are generating above your home’s current consumption — it does not pull from the grid. This is a key differentiator: most other smart chargers can only schedule charging, not dynamically respond to solar output (Myenergi product manual, 2026). The MCS installation guide for solar-compatible chargers confirms this setup is standard for solar-integrated systems (MCS installation guide, 2026).
How to verify your Zappi v2.1 installer — the MCS and OZEV checks you must run
Your installer must be on the MCS (Microgeneration Certification Scheme) register if you want to claim the EVHS grant — check at mcscertified.com. For non-grant installations, the installer should be NICEIC or NAPIT registered for Part P of the Building Regulations (electrical safety) (NICEIC registration check, 2026; NAPIT registration check, 2026).
Always request a G99 or G100 notification from your Distribution Network Operator (DNO) if the charger exceeds 3.68 kW — the installer should handle this (Energy Networks Association DNO guidance, 2026). Do not accept a verbal claim — ask for the installer’s MCS certificate number and check it online before paying.
The Zappi v2.1 works with Octopus Intelligent Go and other smart tariffs — here is what you need to know
Octopus Intelligent Go offers 6 hours at 7.5p/kWh (2026 rate) — the Zappi v2.1 is fully compatible and can be scheduled via the Octopus app (Octopus Energy tariff T&Cs, 2026). OVO Charge Anytime gives 5 hours at 10p/kWh — the Zappi v2.1 works with OVO’s API (OVO Energy tariff T&Cs, 2026). EDF GoElectric offers 5 hours at 9p/kWh — compatible via the Zappi’s built-in timer (EDF Energy tariff T&Cs, 2026).
The Zappi v2.1 does not support OCPP 2.0.1 (only OCPP 1.6) — this means it cannot connect to some newer smart-charging platforms (e.g., some DNO-led V2G trials). Check with your network operator before buying if you plan to participate in future vehicle-to-grid schemes.
How to choose the best smart EV tariff for your home
Is it the best home EV charger for most UK homeowners in 2026?
For most UK homeowners with solar panels, the Zappi v2.1 is the strongest choice because of its solar-excess charging feature and compatibility with the most popular smart tariffs. The ability to charge your EV for free from surplus solar generation can save a typical household £200–£400 per year depending on solar array size and driving habits (Energy Saving Trust, 2026).
For homeowners without solar, the Zappi v2.1 is still a solid 7.4 kW smart charger, but you may pay more than for a simpler OCPP-only charger (e.g., the Ohme Home Pro) that costs £50–£100 less installed. The Zappi v2.1’s 3-year warranty is shorter than the 5-year warranty offered by some competitors (e.g., Hypervolt Home 3) — factor this into your decision (Myenergi warranty T&Cs, 2026; Hypervolt warranty T&Cs, 2026).
Which? EV charger reviews in 2026 rank the Zappi v2.1 highly for solar integration but note that its OCPP 1.6 limitation may be a concern for future-proofing (Which? EV charger reviews, 2026). The Energy Saving Trust’s guide on home charging confirms that solar-compatible chargers offer the best long-term savings for solar-equipped homes (EST home charging guide, 2026).
