A 7kW home charger adds about 30 miles of range an hour on the standard single-phase supply nearly every UK home already has — enough to fully charge overnight. Here's what it is, whether it's enough for you, the real install cost, and how it stacks up against 22kW.
Price my 7kW install →A 7kW EV charger is a home wall-box that delivers up to seven kilowatts of power — the rating that matches the 32A single-phase electricity supply found in almost every UK home. That makes it roughly three times faster than charging from a normal 3-pin plug, and it's the reason 7kW is the default home charger across the country.
In practice, “7kW” describes the speed, not the brand. Ohme, Pod Point, Hypervolt, Easee, Wallbox and Andersen all sell 7kW home units; they differ on app, cable and design, not headline power. Every new install must also be smart-charge compliant by law, so any 7kW unit you fit today supports scheduled off-peak charging out of the box.
A 7kW charger adds roughly 25–30 miles of range for every hour plugged in. That fully refills almost any EV overnight — plug in at 6pm, wake to 100%.
The 7kW rating maps to the 32A single-phase electricity nearly every UK home already has. No 3-phase upgrade, no special supply — that's why it's the default.
You sleep longer than it takes a 7kW unit to charge. A faster 22kW charger finishes sooner, but if you're asleep either way, you've paid for speed you never use.
Two EVs sharing one charger, very high daily mileage, or a home that already has 3-phase power are the situations where 22kW earns its extra cost — for everyone else, 7kW is enough.
The short version: if you charge at home overnight, a 7kW charger is enough. The only people who should look at 22kW are those with a 3-phase supply and two EVs, or genuinely exceptional daily mileage.
Our live UK sample puts a typical 7kW home install at £1,073, with the lowest sampled job at £775. Most of the variation is the electrical work — the cable run from your consumer unit and any board upgrade — not the charger itself.
Renters, flat-dwellers and on-street parkers can take up to £500 off with the grant. See the full breakdown, including the variables that move your price, on the cost page, or run the calculator.
22kW charges about three times faster, but needs a 3-phase supply most homes don't have and costs more to fit — our live sample averages £1,150 for a 22kW install versus £1,073 for 7kW. For overnight home charging, the extra speed is wasted.
A 7kW charger is a home wall-box that delivers up to 7 kilowatts of power on a standard single-phase UK supply — about three times faster than a 3-pin plug. It's the most common home charger rating in the UK because it fully charges almost any EV overnight without any special wiring.
For the vast majority of drivers, yes. A 7kW charger adds around 30 miles of range per hour, which means a full overnight charge for almost any battery. You only need more than 7kW if you regularly do very high mileage, share one charger between two EVs, or already have a 3-phase supply.
Roughly 25–30 miles of range per hour. As a rule of thumb a typical 60kWh EV goes from near-empty to full in about 8–9 hours on 7kW — comfortably within an overnight window, especially on a cheap off-peak EV tariff.
Our live UK sample puts a typical 7kW home install at the average shown above, with the lowest sampled job lower still. Your own price depends mostly on the cable run from your consumer unit and whether the board needs any work. Renters, flats and on-street parkers can take up to £500 off with the grant.
7kW for nearly everyone. 22kW charges roughly three times faster (~90 miles/hour) but needs a 3-phase supply most UK homes don't have, and costs more to install. Unless you have 3-phase power and two EVs, 7kW is the right call.
Almost certainly. A 7kW unit runs on the standard single-phase supply found in nearly every UK home, so no supply upgrade is needed. A qualified OZEV-approved installer fits the unit, runs the cable from your consumer unit and certifies it to the smart-charge regulations.
