Our chargers use Type 2 connectors, which are standard in the UK and compatible with all modern electric vehicles.
Check your car’s manual or visit the manufacturer’s website to see if your car uses a Type 1 or Type 2 connector.
A tethered charger has a charging cable permanently attached to the unit.
An untethered charger doesn’t have a permanent fixed cable.
Having a tethered charger can be more convenient because the cable is always attached, so it’s easy to plug in quickly. But an untethered charger can look neater on the wall.
With an untethered charger, you can still buy the right length charging cable if you need one.
Our expert EV team can help you decide what’s right for you.
Yes. We can only install a charger if you have off-street parking like a driveway or garage, where cabling doesn’t cross public land.
Most EV charger installations are standard. They include:
If you have additional requirements, you may instead need a non-standard installation. This will be assessed by our EV team after you complete your virtual survey. If there are any extra costs, we’ll let you know.
1. The 1.7p per mile calculation is based on the Tesla Model Y, which has an EV efficiency of 4.5 miles per kWh. Dividing the So EV off peak rate of 7.5p by the 4.5 efficiency (between the hours of midnight and 5am) results in the cost of 1.67p per mile (which we round up to 1.7p per mile). We use the Tesla Model Y because it was the UK's best-selling car in 2025.
2. The 600 miles for under £10 calculation is based on a Tesla Model Y efficiency rating of 4.5 miles per kWh. Actual efficiency varies depending on EV make and model, seasonal conditions, driving style, and charging rate. Our estimate uses the So EV charging rate of 7.5p per kWh, offered between 12am and 5am. The precise calculation is 599 miles for £9.98.
3. A public Rapid charger costs EV drivers, on average, £0.79 per kWh. So Energy’s off-peak tariff rate is 7.5p per kWh. Calculations: So Energy off-peak cost per mile of 1.7p and public Rapid charging cost per mile of 17.6p show that you’ll save 91% versus public charging when combining your charger with our EV tariff.
4. The 68% savings claim vs charging on a standard variable tariff is based on our So Flex electricity unit rate of £0.234 per kW vs the So EV electricity unit rate of £0.075 per kW.
