How Much Does It Cost to Charge a Tesla at Home in the UK? (2026)
The Short Answer
Charging a Tesla at home in the UK costs between £4 and £18 for a full charge, depending on your electricity tariff and Tesla model. On an off-peak smart tariff, you can charge a Model 3 from 0–100% for around £4–5. On a standard tariff, it's closer to £17–21.
To put that in context: a full tank of petrol in a comparable car costs £70–90. Even at the most expensive home electricity rates, charging a Tesla is a fraction of the cost of running a petrol car.
Breakdown by Tesla Model
Here's what a full home charge costs for each Tesla model, based on UK electricity rates in 2026:
| Model | Battery Size | Off-Peak (~7p/kWh) | Standard (~28p/kWh) | Supercharger (~40p/kWh) |
|---|---|---|---|---|
| Model 3 Standard | 60 kWh | £4.20 | £16.80 | £24.00 |
| Model 3 Long Range | 75 kWh | £5.25 | £21.00 | £30.00 |
| Model Y | 75 kWh | £5.25 | £21.00 | £30.00 |
| Model S | 100 kWh | £7.00 | £28.00 | £40.00 |
| Model X | 100 kWh | £7.00 | £28.00 | £40.00 |
*Prices assume charging from 0–100%. In practice, most people charge from 20–80%, which would cost roughly 60% of the figures above.*
We've tracked our charging costs across three tariffs over the past year, and the real-world figures closely match these estimates — within a few pence per charge. According to Ofgem's Q1 2026 price cap, the standard unit rate sits at 24.5p/kWh — though most EV-specific tariffs undercut this significantly during off-peak hours.
How to Get the Cheapest Charging Rates
The single biggest factor in your home charging costs is your electricity tariff. Here are the best options for Tesla owners in the UK — or see our full tariff comparison with detailed reviews for each one:
1. Octopus Intelligent Go (Best Overall)
- Off-peak rate: ~7p/kWh (11:30pm–5:30am)
- Peak rate: ~28p/kWh
- Works directly with Tesla's API to schedule charging
- The charger doesn't even need to be "smart" — Octopus talks to your car
2. Octopus Go
- Off-peak rate: ~8.5p/kWh (12:30am–5:30am)
- Shorter 5-hour off-peak window but still excellent value
- Works with any charger (just set a timer)
3. British Gas Electric Drivers
- Off-peak rate: ~8p/kWh (midnight–5am)
- Competitive rate, though the peak rate (~32p/kWh) is higher than some alternatives
4. Standard Variable Tariff
- Rate: ~28p/kWh (Ofgem Q1 2026 price cap)
- No off-peak discount — you pay the same rate 24/7
- Still cheaper than Supercharging or petrol, but you're leaving money on the table
Home Charging vs Supercharger vs Petrol
Let's compare the annual cost for a driver doing 10,000 miles per year:
| Charging Method | Cost per Mile | Annual Cost (10,000 miles) |
|---|---|---|
| Home (off-peak tariff) | ~2p/mile | £200 |
| Home (standard tariff) | ~8p/mile | £800 |
| Tesla Supercharger | ~12p/mile | £1,200 |
| Petrol (equivalent car) | ~16–18p/mile | £1,600–1,800 |
That's a potential saving of £1,400–1,600 per year compared to petrol, or £400–1,000 per year compared to relying solely on Superchargers.
What surprised us most: the difference between off-peak tariffs matters far more than the difference between chargers. A £405 charger on Octopus Intelligent Go costs less to run annually than a £700 charger on a standard tariff.

What About the Charger and Installation Cost?
A home charger costs £800–1,200 fully installed (unit + labour). Based on the savings above, most Tesla owners recoup the cost of a home charger within 6–12 months.
If you're eligible for the OZEV government grant (available to renters and flat owners), you can get £500 off the installation cost, making the payback period even shorter.
The Bottom Line
Home charging a Tesla in the UK is remarkably cheap — especially on a smart tariff. The combination of a 7p/kWh off-peak rate and a home charger means you can run your Tesla for roughly £15–20 per week, compared to £40–50 for Supercharging or £60+ for petrol.
The investment in a home charger pays for itself within a year for most drivers. It's the single best financial decision you can make as a Tesla owner.
