EV charger buying guide 2026

What a home EV charger actually does, and what it doesn't

A home EV charger (or "wallbox", or "EVSE" — electric vehicle supply equipment) is a controlled mains outlet for a car. It manages the handshake with the vehicle, adjusts charging current, and increasingly orchestrates charging around tariffs and solar generation. It does not generate energy. It does not significantly increase your electricity bill on its own — what increases the bill is the EV. And the cheapest way to charge an EV in the UK in 2026 is overnight on a smart tariff at 7–9p/kWh, which means the charger needs to be smart enough to align with your tariff.

The defining question for 2026 isn't "do I need a smart charger?" — the smart-charger regulations made dumb chargers effectively unavailable on new installs. It's "which smart features actually save money and which are marketing?"

7kW vs 22kW: the supply question

The headline kW rating of an EV charger is limited by the household's electrical supply. Most UK homes have a single-phase supply, which limits a domestic charger to 7.4kW (32A at 230V). Three-phase supply allows 22kW (32A across three phases at 400V) but is uncommon in residential properties — you'll have it if you live in a rural area where the network was wired for agricultural loads, in a few new-builds, or after a deliberate upgrade (typically £3,000–£8,000 from the DNO).

The honest answer for 95% of UK homes: 7kW is more than enough. A car plugged in at 6pm and unplugged at 7am has 13 hours to charge — that's 90+ kWh at 7kW, more than any EV battery on the market. Spending money on a 22kW charger when you don't have 3-phase supply is the same as buying a sports car for the school run. You can't use the capability.

Tethered vs untethered

A tethered charger has the cable permanently attached. An untethered (or "socket") charger has a Type 2 socket; you carry the cable in your boot. The trade-offs:

• Tethered: more convenient (no cable to unwrap), neater on the wall, cable lives outside in all weather. The downside: you're locked to whatever cable type and length the charger ships with, and if the cable degrades you replace the whole unit or pay for a service call.
• Untethered: more flexible (any Type 2 cable works, swap for longer one, share cables across multiple chargers), the cable lives in your dry boot or garage. Slightly less convenient day-to-day.

For most households, tethered is the better default. Untethered makes sense if you have multiple cars with different charging needs, a long cable run, or a strong preference for keeping the cable indoors.

Smart features: what actually saves money

Off-peak tariff scheduling

The single most valuable feature. UK smart tariffs — Octopus Intelligent Go, Octopus Cosy, Octopus Agile, OVO Charge Anytime, EDF GoElectric — offer overnight rates of 7–9p/kWh vs daytime rates of 28–35p/kWh. Charging on the cheap rate saves about £800–£1,400 per year for a typical 10,000-mile EV. The charger needs to either schedule charging directly or integrate with the tariff via API. Ohme leads here with native Intelligent Octopus Go integration; most other smart chargers can do simple time scheduling.

Solar diversion (PV diversion)

If you have solar PV, the charger can preferentially use surplus solar power instead of grid electricity. The Zappi from Myenergi popularised this; Wallbox, Andersen and Easee now offer it via different mechanisms. Real savings depend on solar size and driving patterns, but typically £100–£300/year for a 4–5kWp solar system with daytime EV use.

Load balancing / dynamic load management

The charger monitors total household current and reduces charging speed if other appliances are running, to avoid tripping the main fuse. This is essential for any house where a 7kW charger plus heat pump plus oven might exceed the main fuse rating (typically 80A or 100A). Most modern smart chargers do this.

OCPP (Open Charge Point Protocol)

An open standard for chargers to talk to back-end management systems. Useful if you might want to switch tariff providers, integrate with a home energy management system, or run multiple chargers across a small business. Andersen, Wallbox, Easee and several others support OCPP. Ohme historically did not but added partial support in recent firmware.

App and remote control

Useful for monitoring and tweaking schedules but rarely a major value driver. Don't pay extra for a charger because the app looks slick.

The brands actually being installed in 2026

Ohme ePod / Home Pro

UK brand, deepest tariff integration in the market. Native support for Intelligent Octopus Go means the charger and the tariff coordinate without manual scheduling — the car charges when prices are lowest and the system handles the optimisation automatically. Compact ePod (£750–£900 fitted) for tethered installs; the Home Pro adds a screen and untethered option (£900–£1,150 fitted). Best choice for households on Octopus Intelligent Go or Agile.

Myenergi Zappi

The solar-diversion specialist. Three modes: Eco+ (uses only surplus solar), Eco (mixes solar and grid), Fast (full speed on grid). If you have meaningful solar PV (4kWp+) and want maximum self-consumption, Zappi is the leader. Tethered or untethered; typical fitted cost £1,000–£1,300. Tariff scheduling is OK but less polished than Ohme. Pairs well with the Myenergi eddi (hot water diverter) for full energy ecosystem control.

Andersen A2

The premium design choice. UK-made, modular faceplates that conceal the cable inside the unit, broad colour and material options. Build quality is excellent. Functionally it's a competent smart charger with OCPP support and a decent app, though the software is less polished than Ohme. Typical fitted cost £1,300–£1,800. The right choice if visual integration with the house matters and budget allows.

Wallbox Pulsar Plus / Quasar 2

Spanish brand, broad European installer base. The Pulsar Plus is a compact, well-priced 7kW charger (£700–£950 fitted). The Quasar 2 is a bi-directional V2H/V2G charger (£5,500–£7,000 fitted) supporting compatible Nissan, Kia, MG, and Renault models — relevant if you want to use the EV as a home battery. Generally solid, with good Home Assistant and OCPP integration.

Easee One / Charge

Norwegian brand with a distinctive look (no screen, status via LED ring). Strong load balancing, native multi-charger support (you can install three Easee units on one circuit and they balance among themselves), and good OCPP support. Tariff scheduling is competent, though less polished than Ohme. Typical fitted cost £800–£1,000. Good choice for households planning multiple EVs or integration with home energy management.

Grants and funding routes in 2026

The headline change from earlier years: the residential Electric Vehicle Homecharge Scheme (EVHS) ended in March 2022 for most homeowners. What remains:

• EV chargepoint grant for renters and flat owners: up to £350 off the cost of a chargepoint and installation for people in rented accommodation or flats. Eligibility includes proof of off-street parking and the ability to install a charger.
• Workplace Charging Scheme (WCS): up to £350 per socket, up to 40 sockets, for businesses, charities and public-sector organisations.
• EV infrastructure grant for landlords: covers up to 75% of the cost of installing chargepoint infrastructure at residential and commercial rental properties, up to £30,000.
• Local council grants: a handful of councils still offer top-ups; check your specific authority.

Most owner-occupiers buying a charger in 2026 do not qualify for a grant. Quotes that mention "grant available" should be checked carefully — often the grant doesn't actually apply to your situation.

DNO notification: the bit nobody mentions until install day

UK regulations require that any home EV charger install is either notified to or formally approved by the Distribution Network Operator (DNO — the company that runs the local cables, e.g. UK Power Networks, National Grid Electricity Distribution, SP Energy Networks). For most 7kW installs on a single-phase supply, this is a simple notification — a form your installer submits after the work is done. For installs that take total household demand close to the main fuse rating, or for 22kW chargers, the DNO must approve before work starts and may require a supply upgrade.

Your installer should handle this. If they don't mention it, ask. An undocumented EV charger can cause problems if the DNO discovers it and can complicate house sales.

SMETS2 smart meter integration

Most modern smart tariffs require a SMETS2 smart meter installed and operating in "Smart Mode" (talking to the DCC network). The charger doesn't connect to the meter directly — the integration happens at the energy supplier level, with the charger reporting to the supplier's back-end. If you don't have SMETS2, you can't use Octopus Intelligent Go and most equivalent tariffs — even with a smart charger. Get the meter installed first if you don't have one; suppliers fit them for free.

Red flags — when not to buy or what to avoid

• 22kW charger sold to a single-phase home. It will physically install and run at 7kW, but you've paid extra for nothing. Common scam pattern.
• Quotes that don't include the consumer unit upgrade. Some older fuse boards need upgrades or new RCD/RCBO protection for an EV charger circuit. A complete quote includes this; a cheap quote often hides it.
• Non-OZEV-approved installers. Even if you don't qualify for a grant, OZEV approval indicates the installer has demonstrated competence on EV-specific work. Ask for the OZEV certification number.
• Cheap chargers from unknown brands. The hardware is usually fine; the back-end software, firmware updates, and OCPP support are usually not. A £400 charger from an unknown brand can become an expensive paperweight when the cloud service shuts down.
• Tariff lock-in pitches. Don't pay extra for "exclusive" tariff partnerships unless you've checked the alternative tariffs you'd be cut off from. The market is fluid and exclusivity in 2026 may not be worth it in 2027.
• Aggressive solar+battery+EV bundles. Buying everything at once from one installer locks you into one ecosystem. Modular purchases over 1–3 years usually deliver better value.
• Long cable runs at thin gauge. If your charger needs to be 25m+ from the consumer unit, the cable has to be specified for that distance with appropriate voltage drop. Cheap quotes can skimp here.

Realistic costs in 2026

FAQ

Q: How much does it cost to charge an EV at home?

A: On a standard tariff at ~28p/kWh, a typical 60 kWh battery costs about £17 to fully charge from empty. On a smart tariff at 7–9p/kWh overnight, the same charge is £4–£5. For a typical 10,000-mile-per-year driver, the difference is £800–£1,400 per year.

Q: Do I need to upgrade my main fuse for a 7kW charger?

A: Usually not. A 7kW charger draws 32A; most UK homes have an 80A or 100A main fuse, and load balancing in modern chargers prevents the main fuse tripping. The DNO assesses this when notified. Older homes with 60A fuses may need an upgrade.

Q: Can I install an EV charger myself?

A: Technically possible for a competent electrician, but you'll need to register the install with Building Control via Part P, do the DNO notification, and you're not eligible for any grants without OZEV-approved installation. For most people, hiring an OZEV-approved installer (typical labour £200–£400) is the right call.

Q: What about V2G / V2H?

A: Vehicle-to-grid (V2G) and vehicle-to-home (V2H) let the EV battery push power back to the grid or the house. The Wallbox Quasar 2 and Sigenergy SigenEVDC support this; compatible cars include Nissan Leaf, Kia EV6/EV9, MG MG4, BYD Atto 3 (subset of trims), and Renault 5. Economics can work for low-mileage drivers but the bi-directional charger costs £3,500–£5,500 more than a normal one. Most households are still better with a one-way charger and a separate home battery.

Q: Will any cable / charger work with any car?

A: For AC charging (home wallbox), all modern EVs sold in the UK use Type 2 connectors. Tethered chargers ship with Type 2 cable so they work universally. Older Type 1 cars (some early Mitsubishi Outlander PHEV, Nissan Leaf gen 1) need a Type 1 to Type 2 adapter cable.

Q: How long does a home charger last?

A: 8–12 years for a quality unit. Software/cloud support depends on the manufacturer continuing to invest. Brands with OCPP support age better because you can swap the back-end if the original cloud is shut down.

Q: Will a charger work in a power cut?

A: No. Standard chargers shut off when grid power is lost. Some bi-directional chargers paired with home batteries can run as backup during an outage, but this requires specific configuration and adds cost.

Bottom line

For most UK households in 2026: Ohme ePod or Home Pro if you're on Octopus Intelligent Go — the tariff integration alone justifies the choice. Zappi v2.1 if you have meaningful solar PV and want maximum self-consumption. Wallbox Pulsar Plus for a strong all-rounder at a competitive price. Easee One/Charge if you want best-in-class load balancing or plan multiple chargers. Andersen A2 if visual integration with the house matters and budget allows.

Single-phase 7kW is the right answer for nearly every UK home. Don't pay for capabilities your supply can't deliver. Get the smart tariff sorted before the charger; without it, the charger is just an expensive socket.
