Home EV charging: what you actually need and what it costs

The number of electric cars on UK roads crossed the two million mark in 2025, and for most of those drivers, the charging question gets settled not at a motorway services but on their own driveway. Home charging is where the vast majority of EV miles happen. It is also where most people’s confusion begins. Which charger do you actually need? What will installation cost? And is there any point in going for a smart model over a basic one?

The short answer is that home charging is simpler and cheaper than most people expect, but the right setup depends on a few variables that are worth understanding before you spend any money.

Start with the basics. Every electric car in the UK comes with a cable that plugs into a standard three-pin socket. This is often called a granny charger in EV circles, and it works exactly the way it sounds: slowly. A typical three-pin socket delivers around 2.3kW, which adds roughly eight to ten miles of range per hour. For many people who drive fewer than thirty miles a day and can leave the car plugged in overnight, this is genuinely enough. You do not need to buy anything extra to start charging at home.

The reason most EV drivers still invest in a dedicated home charger, often called a wallbox, is speed and convenience. A standard wallbox delivers 7kW, which charges most family EVs from near-empty to full in six to eight hours. In practice, that means plugging in when you get home and leaving the car ready by morning without thinking about it. Faster 22kW AC chargers are available, but most home electrical supplies are single-phase, meaning you cannot practically run one at home. The 7kW wallbox is the real-world standard for UK driveways.

The main brands you will encounter are Pod Point, Ohme, Zappi, and Wallbox. Each has a different emphasis. Pod Point is the most widely installed in the UK and is known for reliable simplicity. Wallbox makes aesthetically clean units with strong app integration. Zappi is the specialist choice if you have solar panels, because it can divert surplus solar generation into your car rather than exporting it to the grid at low rates. Ohme is the standout option if you are on a smart energy tariff, because it integrates directly with suppliers like Octopus Energy and can automatically schedule charging to the cheapest overnight slots without you lifting a finger.

Installation costs sit between £500 and £1,000 for most households, including the unit and fitting. The UK government’s EV chargepoint grant covers up to £350 towards the cost, available to anyone living in a flat or renting a property (owner-occupiers in houses do not currently qualify, though the scheme does change periodically). Installers must be OZEV-registered to carry out the work, and the grant is applied through accredited installers rather than claimed separately afterward.

The area where it is worth spending slightly more than the minimum is smart charging. A basic charger just pushes electricity into your car at full speed and full price whenever you plug in. A smart charger connects to your home Wi-Fi and lets you schedule charging through an app, set it to run overnight, and in some cases link directly to your energy tariff. This matters because time-of-use tariffs like Octopus Go price electricity at very different rates depending on when you use it. Off-peak overnight electricity on Octopus Go currently costs around 7 to 10 pence per kilowatt hour, compared to the standard daytime rate of 24 to 25 pence. If you are charging a 60kWh battery from near-empty, the difference between peak and off-peak comes to around £9 per session. Multiplied across a year of regular charging, that saving adds up quickly.

The Ohme charger’s integration with Octopus works particularly well here. You link your account, and the charger automatically identifies the cheapest hours in the overnight window and charges then. You do not need to set a schedule manually or check prices. Zappi does something similar for solar owners, but instead of targeting cheap grid electricity it uses solar generation that would otherwise go to waste. If you have panels already, or are planning to add them, Zappi is the natural pairing.

The thing most people get wrong when thinking about home EV charging is assuming it will be expensive to run day to day. The reality is that once a wallbox is installed, charging at home costs roughly a quarter of what you would pay at a public rapid charger and around a third of the cost of filling a petrol car. A typical 60kWh family EV, driven 10,000 miles a year, costs around £200 to £400 to charge at home depending on your tariff, compared to £1,200 to £1,500 in petrol. The savings compound quickly, and they are available from the first day you switch.

What catches people out is a related assumption: that the three-pin socket is unsafe or inadequate for regular use. It is not ideal for nightly full charges, because it draws sustained current through a socket designed for occasional heavy use rather than continuous overnight loads. A dedicated wallbox has proper circuit protection built in. If you are charging every night, a wallbox is the right long-term setup. If you charge every few days and your commute is short, the standard cable will do the job while you figure out the rest.

The practical starting point is straightforward. If you are new to an EV and not yet on a smart tariff, install a basic 7kW wallbox, switch to Octopus Go or a similar time-of-use tariff, and let overnight charging become a habit. If you already have solar panels or are interested in energy optimisation, look at Zappi or Ohme. Either way, the effort is in the initial setup decision. After that, most EV drivers say they think about charging at home roughly as often as they think about charging their phone, which is to say, barely at all.
