Save up to 86% when you charge your EV at home

'Tethered' means there is a cable permanently attached to the charging box at one end.

'Untethered' means that a cable plugs into your car at one end and the box at the other. So you'll be able to source your own cable to charge your EV. For example, the one that was delivered with your EV.

Your cable will need to be long enough to comfortably reach your EV from your chargepoint. Depending on the brand you chose, the cables of our tethered EV chargers are between 5 and 8 metres long. Generally, this is enough for most houses where the box is on the outside of the house and the car is parked on a driveway.

A standard installation is included in the price of your charger. But if the installation is more complex and our engineers will need to spend more time at your home, it'll cost a bit more.

Our EV chargepoint installations are grouped into three categories. See the table below for what's included in each installation package:

We can only install a charger if you have private parking (like in a driveway or garage, with no public lands between your house and the charger). If the cable will need to cross public lands, we recommend that you look at a solution like Kerbo Charge.

Save up to 86% vs public charging when you power up at home

A slow or fast charge (<50 kWh) with one of the UK's public charging points costs an EV driver 54p/kWh on average (last checked February 2026). With Intelligent Octopus Go, you smart charge for only 7.5p/kWh and save 86%. .

Save £973 a year on your fuel costs with an EV vs a petrol car

This is the difference in annual cost to smart charge an average electric car on our Intelligent Octopus Go tariff (£163) versus fueling the average petrol car (£1,136).

Annual cost to charge with Intelligent Octopus Go = A*B*C = 7,100 miles * 0.307 kwh/mile * 0.075 £/kWh = £163.48

Annual cost to fuel a petrol car = A*D = 7,100 miles/year * 0.16 £/mile = £1,136 per year

A - 7,100 average annual mileage (gov.uk)
B - 0.307 kWh/mile average electric car efficiency (EV database)
C - 7.5p/kWh Intelligent Octopus smart charging rate, assuming you're smart charging for a maximum of 6 hours/day. Check if you're eligible.
D - 0.16 £/mile average cost per mile for a petrol car (gov.uk)
