Electric car charger: UK home charger guide (costs, types & installation)
If you want the simplest, cheapest way to run an EV in the UK, home charging is usually the win. This guide explains which electric car charger to buy, what it typically costs to install, and what to check before you book an electrician — plus how to cut your p/kWh with the right tariff.
What is an electric car charger?
In everyday UK conversation, “electric car charger” usually means a dedicated home charge point installed on an exterior wall or in a garage. Technically, the charger is inside your car — the wall unit is a charge point that safely delivers power and adds useful features like scheduling, safety checks and (often) smart control.
Charger types: 3-pin vs 7kW vs 11/22kW (what most UK homes can use)
1) 3-pin plug (granny charger)
Best for: occasional top-ups, very low daily mileage.
- Slow, but works almost anywhere.
- Use a healthy, correctly rated socket; avoid flimsy extensions.
- Useful as a backup, not ideal as your main setup.
2) 7kW home charger (single-phase)
Best for: most UK households with a driveway.
- Typically the most practical “overnight charge” option.
- Works on the standard UK single-phase supply (common).
- Pairs well with off-peak EV tariffs.
3) 11kW / 22kW (three-phase)
Best for: homes with three-phase power (less common) or specific needs.
- May require a three-phase supply upgrade (often expensive).
- For many drivers, 7kW already covers overnight charging.
- Most value comes from tariff timing, not sheer power.
Tethered vs untethered: which electric car charger is better?
Tethered chargers have a cable permanently attached — quickest day-to-day (grab cable, plug in). Untethered chargers use a socket so you bring your own cable — neater and more flexible if you switch cars. If you’re buying for “family proof” simplicity, tethered usually wins.
Smart chargers: what “smart” actually means (and the UK rules)
A smart electric car charger can schedule charging, report energy use, and (depending on tariff/brand) automatically charge when electricity is cheapest. In the UK, “smart charge point” functionality is also shaped by regulations designed to shift charging away from peak demand and improve device security and consumer information. Read the UK smart charge point regulations.
How much does a home electric car charger cost in the UK?
As a rough planning range, many UK installs for a 7kW home charger land around £800–£1,200 for a straightforward job (charger + fitting), with higher costs if you need longer cable runs, groundworks, or consumer unit upgrades. (Always get quotes — properties vary.)
Is there a grant?
There are UK schemes that can contribute to install costs in specific situations — for example the Electric Vehicle Chargepoint Grant for renters and flat owners can contribute up to £350. Check the latest eligibility and deadlines here: EV chargepoint grant for renters and flat owners.
Installation checklist (what to check before you book)
1) Parking + cable route
Where will the car park most nights? Shorter, simpler cable routes usually reduce cost and hassle.
2) Supply + consumer unit
Older boards may need updates. Your installer will assess protective devices and earthing arrangements.
3) Choose tethered/untethered
Pick based on convenience vs flexibility and how tidy you want the front of the house to look.
4) Pick features that actually matter
Scheduling + energy reporting + app stability are usually more valuable than flashy extras.
5) Use a qualified installer
EV charge points involve household electrical work and must meet UK safety requirements. Use a reputable installer who provides the appropriate certification on completion.
Tariffs: the part most people forget (and where the savings live)
You can buy the best electric car charger on the market and still overpay if you charge on a flat-rate tariff at peak prices. The biggest “day one” win is often switching to an EV-friendly tariff and scheduling charging into the cheap window. Use: EV tariff comparison table or the homepage quick calculator to estimate your real-world cost.

Do I need a smart meter for a home electric car charger?
You don’t always need one for the charger to work, but many EV tariffs and “smart” scheduling benefits are much easier with a smart meter.
Is a 7kW charger enough?
For many UK drivers charging overnight, yes. The deciding factor is your daily miles and how long you can reliably plug in.
Can I get a grant for an electric car charger?
Possibly. UK eligibility depends on your situation (for example renters/flat owners). Always verify current rules and deadlines before purchase: grant details here.
What’s a realistic installed cost in the UK?
For a straightforward 7kW install, many people budget around £800–£1,200, with higher costs for complex cable runs, groundworks, or board upgrades.
Prices and schemes can change. Always confirm live tariff rates and any grant eligibility before switching supplier or buying hardware.
