Installing a home EV charger — hardware, permits & realistic costs
Home charging is the single biggest reason EV ownership beats petrol on running cost. Here's the hardware that's worth buying in 2026, the electrical requirements, permits to be aware of and what installations actually cost in the UK, France, Italy and Australia.
Step 1 — Electrical requirements
Supply
Single-phase (UK/AU): 7.4 kW max. 3-phase (FR/IT/EU): 11 or 22 kW. A site survey confirms your fuse rating (typically 60–100 A).
Compliance
UK installs must follow BS 7671 18th Edition; FR uses NF C 15-100; IT uses CEI 64-8; AU uses AS/NZS 3000. Always use a certified installer.
DNO notification
Anything ≥3.6 kW needs notifying your network operator. >7.4 kW (and most 3-phase) requires pre-approval — adds 1–4 weeks.
Step 2 — Hardware comparison
| Model | Power | Smart | Price | Notes |
|---|---|---|---|---|
| Wallbox Pulsar Plus | 7.4 / 22 kW | Yes (Wi-Fi, OCPP 1.6) | £549–£899 / €549–€899 | Most compact 22 kW unit on the market. |
| Tesla Wall Connector Gen 3 | 7.4 / 22 kW | Yes (Wi-Fi, no OCPP) | £475 / €500 / A$795 | Works with any EV, not just Tesla. No tariff API. |
| Easee Charge | 7.4 / 22 kW | Yes (full OCPP, load-balancing) | £525 / €549 | Best for multi-charger sites and dynamic load balancing. |
| Zappi v2.1 | 7.4 kW | Yes (solar PV integration) | £899 / €999 | Solar/battery owners — diverts surplus PV to the EV. |
| Ohme Home Pro | 7.4 kW | Yes (Octopus Intelligent ready) | £449 | Cheapest smart wallbox in UK, deep Octopus tariff integration. |
Step 3 — Permits & paperwork
- ✓UK: Building Regs Part P compliance + DNO notification within 28 days
- ✓France: déclaration préalable in conservation zones; Consuel certificate post-install
- ✓Italy: CILA filing for any new circuit + ENEL load-increase if upgrading
- ✓Australia: CES (Certificate of Electrical Safety) in VIC, NoSW in NSW
Step 4 — Cost by country
United Kingdom
£800–£1,200 fully installed
Standard install on a single-phase home, <10 m cable run. DNO upgrade adds £200–£600.
France
€900–€1,500
Single-phase install. ADVENIR credit reduces 30–50%. 3-phase 22 kW commonly +€300.
Italy
€1,000–€1,800
Plus CILA filing fee €150–€300. Detrazione fiscale (50% over 10 years) applies.
Australia
A$1,500–A$2,500
Higher due to safety switch upgrades and remote installer travel in regional areas.
Home charging at off-peak tariffs (Octopus Go in UK, EDF Tempo in FR, Enel X in IT) can cost as little as 7p/kWh — over 80% cheaper than rapid public charging. Use our charging calculator to model your annual savings.

Frequently asked
Do I need a 3-phase supply to install a home charger?
No. Single-phase (most UK and AU homes) supports up to 7.4 kW — enough to fully charge any EV overnight. 3-phase (common in France, Italy and parts of AU) unlocks 11 kW or 22 kW for faster refilling.
How long does a home installation take?
A standard installation is 2–4 hours by a certified electrician once the unit is on site, plus 1–2 weeks lead time for the survey and DNO/network operator notification.
Do I need planning permission?
In the UK, most external wallbox installs are permitted development. In France a déclaration préalable may be needed in listed conservation areas. In Italy a CILA filing is typical. Australia varies by state but is rarely required for owner-occupied homes.
Is a tethered or untethered charger better?
Tethered = cable always attached; faster plug-in. Untethered = cleaner aesthetics, future-proof if you change cars/connector. Most installations are now untethered Type 2 sockets.
Can I claim a grant for home charger installation?
UK offers the EV Chargepoint Grant (£350) for flat-dwellers and landlords. France's ADVENIR programme covers up to 50% of installation costs. Italy includes wallbox costs under the 50% Bonus Mobilità. Australia has state-specific rebates in NSW and ACT.
