Is a 22kW EV Charger Right?
A 22kW charger can cut charging time, but only if your car accepts 22kW and your property has a suitable three-phase supply. We check both before recommending the practical route for your home or business.
What to Consider Before Choosing a 22kW Charger
Before choosing a 22kW home charger, consider the electricity supply, cable route, parking position, charging habits and installation rules. These details affect the work involved, the equipment required and whether a lower-rated charger may be more practical.
Your car’s charging limit
A 22kW charger only delivers 22kW when the car’s onboard charger accepts it. We check the vehicle specification first, so you don’t pay for capacity the car cannot use.
A suitable three-phase supply
Your property needs a suitable three-phase electricity supply for 22kW charging. We assess the incoming supply, consumer unit and available capacity before confirming whether the installation is practical.
The route from supply to parking
A longer cable route, detached garage or driveway crossing can increase installation work. We plan the cable path around the building and parking position, keeping the finished installation tidy and protected.
Your usual parking pattern
If the car is parked for several hours, a lower-rated charger may already meet your needs. We compare charging time with how far you drive and when the vehicle is normally at home.
Managing the household load
Your charger will share electricity capacity with the rest of the property. We check the expected load from heating, cooking, solar panels and batteries, then include suitable load management where it is needed.
Electrical safety and certification
A 22kW charger needs the correct protective equipment, earthing and testing. Our NICEIC-registered electricians complete the installation and provide the electrical certification for your records.
Future changes to the property
If you plan solar panels, battery storage or another electric vehicle, tell us before the installation. We can assess the wider electrical setup so the charger does not restrict later work.
22kW Compared with Other EV Charging Options
The main choice is between a 7kW home charger, a 22kW three-phase unit, or using public rapid charging when needed. Comparing installation cost, charging speed, electricity capacity and future flexibility shows which route earns its space at your property.
7kW home charger
For most homes, a 7kW unit works with a standard single-phase supply and charges overnight. We check the consumer unit, cable route and available capacity before installing it, so the charger fits the property without an unnecessary supply upgrade.
22kW three-phase charger
A 22kW unit only helps when the car accepts 22kW AC and the property has three-phase power. We confirm both points, assess the incoming supply and check the cable route before recommending the extra installation work.
Public rapid charging
Public rapid charging suits occasional longer journeys, but it does not replace convenient home charging. If a 22kW installation needs major electrical work, we compare that cost and practicality with charging at home on 7kW and using rapid chargers when required.
What changes the decision
Your driving pattern, car, supply and parking arrangement matter more than the charger's headline speed. We use the survey to establish how much charging you need, whether three-phase power is available and which option gives the least disruption.
A clear installation route
If the property needs a longer cable run, consumer unit work or a supply assessment, we include it in the written quotation before work starts. You can then compare the 22kW option with a simpler 7kW installation without surprise charges.
What a Properly Specified 22kW Installation Includes
A three-phase supply still needs checking before a 22kW charger is connected. We assess capacity, cable route, earthing and protective devices, then identify required upgrades.
The finished installation should include clear controls and certification under the relevant electrical regulations. We test the charger, explain its settings and provide paperwork showing what was fitted and how to use it safely.
Three-phase supply check
Your property needs a suitable three-phase supply, so we check capacity before recommending a 22kW charger.
Vehicle compatibility
Your car must accept 22kW AC charging. We confirm its onboard charger rating before specifying the installation.
Load and protection assessment
Existing demand affects the available capacity, so we assess the supply, earthing and protective devices for safe operation.
Suitable cable route
The cable route affects disruption and cost. We plan the run from the supply to the charger before work starts.
Charger controls explained
You receive clear guidance on charging settings, scheduling and safe everyday use once the charger has been tested.
Testing and certification
We test the completed installation and provide the electrical certification and paperwork for the work carried out.
Questions to Ask Before Choosing a 22kW EV Charger Installer
How long does a 22kW EV charger installation take?
Your car’s onboard charger sets the actual charging rate, not the cable alone. We verify its specification first, so a three-phase installation brings a genuine benefit rather than unnecessary expense.
Is a 22kW home charger suitable for an older property?
An older property can still take a 22kW charger. We assess the wiring, consumer unit and installation route, identifying upgrades or planning constraints before recommending a safe, workable arrangement on-site.
How much does a 22kW EV charger installation cost?
Installation cost depends on the charger, cable length, groundworks and any supply upgrades. After surveying these, we provide a written quotation before work starts, with no surprise charges added later.
Does a 22kW EV charger need a dedicated circuit?
A 22kW charger needs its own circuit because its sustained load cannot share safely with general sockets. We size the cable and protection for the supply, route and chosen charger.
Do I need planning permission for a 22kW EV charger?
Many domestic chargers fall under permitted development, but listed buildings, conservation areas, flats and unusual cable routes may differ. We check the proposed position and flag any application before installation.
