7kW vs 22kW EV Chargers: Which Is Best for Home Charging?

If you're considering installing an EV charger at home, you've probably come across both 7kW and 22kW charging options. While 22kW chargers may appear faster on paper, the reality is that for most UK homeowners, a 7kW charger is the smarter, more practical choice.

What Is a 7kW EV Charger?

A 7kW charger is the standard home charging solution in the UK. It operates from a single-phase electrical supply, which is what the vast majority of UK homes already have.

A 7kW charger can typically add around 25–30 miles of driving range per hour and can fully charge many electric vehicles overnight.

What Is a 22kW EV Charger?

A 22kW charger is a much faster charging unit, but it requires a three-phase electrical supply. Most UK homes do not have a three-phase connection, meaning expensive electrical upgrades are often required before a 22kW charger can even be installed.

In addition, many electric vehicles cannot accept the full 22kW charging speed when charging on AC power.

Why 7kW Chargers Are the Best Choice for Most Homes

Lower Installation Costs

Because 7kW chargers work with a standard UK single-phase supply, installation is usually simpler and more affordable.

Perfect for Overnight Charging

Most EV owners charge their vehicles overnight. A 7kW charger provides more than enough power to fully recharge a vehicle while you sleep.

Compatible With Most Electric Vehicles

A 7kW charger works with virtually all modern EVs using a Type 2 connection, making it a future-proof choice for most drivers.

Smart Charging Features

Modern 7kW smart chargers offer:

  • App control

  • Scheduled charging

  • Energy monitoring

  • Off-peak tariff integration

  • Remote charging management

Better Value for Money

Many drivers find that paying significantly more for a 22kW installation offers little real-world benefit when a 7kW charger already meets their daily charging needs.

When Does a 22kW Charger Make Sense?

A 22kW charger may be suitable for:

  • Commercial premises

  • Fleet operators

  • Businesses with multiple EVs

  • Properties that already have a three-phase electrical supply

However, these situations are far less common than standard residential charging requirements.

The Verdict

For most UK homeowners, a 7kW EV charger delivers the ideal balance of charging speed, affordability, convenience, and compatibility.

Rather than paying for costly electrical upgrades and charging speeds that many vehicles cannot fully utilise, most EV drivers will find a smart 7kW charger provides everything they need for reliable daily charging.
