The hardware
A 7 kW wallbox covers every Model 3 sold in the UK. The Standard Range is capped at 7.4 kW on AC anyway — exactly what a single-phase supply delivers; the Long Range and Performance can accept 11 kW on three-phase, which 95% of UK homes can't supply. The car is one of the most efficient saloons on the road, and the charging side reflects that: there's not much to overthink.
Variants (2026)
| Variant | Battery | Max AC | Max DC | WLTP range |
|---|---|---|---|---|
| Standard Range (RWD) | 60 kWh | 7.4 kW (single-phase) | 170 kW | 272 miles |
| Long Range (AWD) | 75 kWh | 11 kW (three-phase) | 250 kW | 391 miles |
| Performance (AWD) | 75 kWh | 11 kW (three-phase) | 250 kW | 365 miles |
7.4 kW for the Standard Range, 11 kW only if you happen to have three-phase. Most UK owners charge at 7 regardless of variant.
How long it takes to charge a Model 3
20% to 80% — the everyday window
| Variant | 3 kW (3-pin) | 7 kW (wallbox) | 11 kW (three-phase) |
|---|---|---|---|
| Standard Range (60 kWh) | ~12 hours | ~5 hours | ~5 hours |
| Long Range (75 kWh) | ~15 hours | ~6.5 hours | ~4 hours |
| Performance (75 kWh) | ~15 hours | ~6.5 hours | ~4 hours |
The Standard Range tops out at 7.4 kW on AC, so three-phase makes no difference for that variant.
0% to 100%
| Variant | 3 kW (3-pin) | 7 kW (wallbox) | 11 kW (three-phase) |
|---|---|---|---|
| Standard Range (60 kWh) | ~20 hours | ~8.5 hours | ~8.5 hours |
| Long Range (75 kWh) | ~25 hours | ~10.5 hours | ~7 hours |
| Performance (75 kWh) | ~25 hours | ~10.5 hours | ~7 hours |
Plug in at 10pm on a 7 kW wallbox and the car is full by morning. For a 30–50-mile commute, an hour or two each night is enough. A 3-pin plug just about keeps up with a quiet week; weekends are where it loses.
What it costs to charge a Model 3 at home
The tariff does almost all the work. The Model 3 manages around 3.9 miles per kWh in real UK driving, winter included — among the most efficient cars sold in the country.
Cost per charge, 20% to 80%
| Variant | Off-peak (8p/kWh) | Standard (26.11p/kWh) | Supercharger (~40p/kWh) |
|---|---|---|---|
| Standard Range (36 kWh) | £2.88 | £9.40 | £14.40 |
| Long Range (45 kWh) | £3.60 | £11.75 | £18.00 |
| Performance (45 kWh) | £3.60 | £11.75 | £18.00 |
Cost per full charge
| Variant | Off-peak (8p/kWh) | Standard (26.11p/kWh) | Supercharger (~40p/kWh) |
|---|---|---|---|
| Standard Range (60 kWh) | £4.80 | £15.67 | £24.00 |
| Long Range (75 kWh) | £6.00 | £19.58 | £30.00 |
| Performance (75 kWh) | £6.00 | £19.58 | £30.00 |
Annual cost at 10,000 miles
| Tariff | Cost per mile | Annual cost | Saving vs petrol |
|---|---|---|---|
| Off-peak (8p/kWh) | ~2.1p | £205 | £1,395 |
| Standard (26.11p/kWh) | ~6.7p | £670 | £930 |
| Supercharger (40p/kWh) | ~10.3p | £1,026 | £574 |
| Petrol equivalent | ~16p | £1,600 | — |
Based on 3.9 miles per kWh (real-world UK average, winter included). Petrol assumes 40 mpg at £1.45/litre.
The gap between standard rate and an off-peak EV tariff is worth around £465 a year on typical mileage — the single biggest lever on running costs. Picking the right charger is second. Most owners want both. The interactive savings calculator does the maths for your mileage; the UK EV Charging Cost Index sets it against every UK tariff.
Choosing a Model 3 charger
Every charger we cover pairs with the Model 3 — the Type 2 connector is universal in the UK, so you're not locked into Tesla's own hardware.
The default is the Tesla Wall Connector at £475 — cheaper than most premium-brand rivals, the longest cable in the round-up at 7.3 metres, and the app already on your phone. Power-sharing across up to six units matters if a second Tesla joins the household. It isn't OZEV-approved, so renters and flat owners lose the £500 grant; for them, the Easee One below is the like-for-like that keeps it.
For a smart tariff, the Ohme Home Pro at £539 talks directly to Octopus, OVO and British Gas. On Intelligent Go it schedules within the off-peak window without you touching it; on Agile it reads next-day prices in half-hour increments. Over a year, the automation tends to find £50–100 more than scheduling by hand. Solar diverting comes built in.
If solar's part of the picture, the Zappi GLO at £599 routes surplus into the car. The Standard Range's 60 kWh battery is small enough that a 4 kW array can fill it almost entirely from surplus on long summer days; in winter, switch to grid top-up.
For grant-eligible buyers, the Easee One at £489 is the cheapest way in — compact, reliable, with a 4G SIM included so it works where Wi-Fi doesn't reach. It's OZEV-approved, and at £489 the £500 grant covers the unit outright, which makes it the cheapest installed option here.

Battery care
The Model 3 battery is warranted for 8 years or 100,000 miles (120,000 on Long Range and Performance) at 70% capacity retention. It will outlast most of what people worry about over a decade of ownership. Two habits do most of the work: set the daily charge limit to 80% in the Tesla app, and try to keep the car between 20% and 80% in normal use. 100% is for trips. 0% is best avoided.
DC fast charging puts more heat through the cells than overnight AC, but Tesla designed the car for it — the right balance is mostly home charging with the occasional Supercharger on long days. Going on holiday, leave it at 50–60%. Heading to a Supercharger off-route? Tap the pin on the map first so the car preconditions the pack on the way.
Heat does more damage than cold. The UK climate is gentle by global standards; in heatwaves, park in shade if you can. That's most of it.
Common questions
Can I charge a Model 3 from a 3-pin plug?
Yes. Tesla includes a Mobile Connector that plugs into a standard 3-pin socket and charges at ~2.3 kW — about 8 miles of range per hour. Fine as backup or for very low mileage; not a daily solution. Full guide to 3-pin plug charging.
Is 7 kW fast enough?
For nearly everyone, yes. At 7 kW you add ~25 miles of range per hour, so an 8–10 hour overnight session covers 200–250 miles. The only Model 3 owners who feel the limit are people doing 200+ mile days back-to-back with no margin to plug in.
Do I need a Tesla-specific charger?
No. Every UK Tesla uses a standard Type 2 connector. Any home charger with a Type 2 plug works. More on Tesla vs third-party chargers.
Is it worth upgrading to three-phase?
For nearly all Model 3 owners, no. The Standard Range can only take 7.4 kW on AC — three-phase makes no difference at all. The Long Range and Performance can take 11 kW, but 95% of UK homes are single-phase, and a £3,000–5,000+ supply upgrade isn't paid back by saving an hour or two overnight.
