For most UK homes, the right charger is a 7.4 kW smart wallbox with a Type 2 connector, sold for the British market and installed by an approved installer. The UK decision is narrower than the global one: a few legal and supply checks come first, and only then do cable style and app features matter.
Key Takeaways
- In Great Britain, a home charge point must be smart by law; compliance comes before features.
- Most UK homes take a 7.4 kW single-phase unit; 22 kW needs a three-phase supply.
- Buy the UK-market version with Type 2 and the right marking, not a grey import.
- Choose tethered or untethered last, and use an approved installer where a grant is involved.
Check 1: It Must Be a Smart Charger, by Law
Since June 2022, private charge points sold in Great Britain for home and workplace use must meet the Electric Vehicles (Smart Charge Points) Regulations 2021. In practice, a compliant unit can schedule charging, is set to avoid peak hours by default, and meets the regulations’ security requirements. A charger that cannot do these things should not be on sale for a UK home at all, so treat “smart” as a legal floor, not an upgrade. If a listing says nothing about the regulations, ask the seller directly before you pay.
Check 2: Power That Matches a UK Supply
Most UK homes have a single-phase supply, and the standard home charge point is 7.4 kW on that supply. A 22 kW unit only delivers 22 kW on a three-phase supply, which most houses do not have. Your installer checks the supply, main fuse and earthing as part of the survey, following the IET Code of Practice for EV charging installations.
| Your situation | What to buy | Why |
|---|---|---|
| Single-phase home, one EV | 7.4 kW smart wallbox | The standard UK fit; refills a typical battery overnight |
| Three-phase supply, or a second EV planned | 22 kW-capable wallbox | Uses the three-phase supply now, runs at lower power if the car limits it |
| Renting, or no fixed parking spot | Type 2 portable charger | No installation to undo when you move |
Check 3: Marking and Connector for the British Market
The connector is settled: UK and European cars use Type 2 for AC charging. The marking needs one question. Products placed on the Great Britain market follow the UKCA route, while CE marking is recognised in defined cases; our explainer on UKCA vs CE for chargers sold in Great Britain sets out which applies when, and our wider guide to EV charger certifications explains what each mark does and does not prove. Buy the version sold for this market, not a grey import listed for another one.
Check 4: Tethered or Untethered, Then the Installer
With the legal and supply checks done, the remaining choices are daily-life ones. A tethered unit keeps its cable attached; an untethered unit has a socket, and you use the cable that came with the car.
Our comparison of tethered vs socketed wallbox chargers works through the trade-offs. Finally, the installer matters as much as the unit: grant-funded installs must use an approved installer, and every install has to be notified to the local distribution network operator, which the installer normally handles. Our guide to claiming the EV charger grant in the UK, Ireland and the US covers who still qualifies, since the UK scheme now targets specific groups such as renters and flat owners rather than all homeowners.
A UK-Ready Example
The EV-ACT3204PE 22 kW wallbox offers three-phase Type 2 charging with a tethered-cable version, RFID and app control, and CE marking; on a single-phase UK home it runs as a 7.4 kW-class unit, and on three-phase it can use its full rating. For a portable option, the EV-ACS3210E 32A Type 2 portable charger delivers about 7 kW single-phase and is IP66 rated. Ask your installer to confirm the exact model against the smart charge point regulations before ordering.
Frequently Asked Questions
Is 7.4 kW enough for a UK home?
For most homes, yes. It is the standard single-phase rating and refills a typical EV battery over a night’s parking. More power only helps if the supply and the car both support it.
Can I install a charger myself in the UK?
A home charge point is fixed electrical work that must meet the wiring regulations and be notified; use a qualified installer. Approved installers are also required where a grant is claimed.
Do I need planning permission for a home charger?
Most home wallboxes fall within permitted development, but flats, listed buildings and conservation areas have extra rules. Check before you book the install if any of those apply.
