What’s the story?
This system was set up on Managing Director Will’s property in Oakham in September 2023. This provides a great example of how you can upgrade your house’s energy system to charge an EV.
Key components of this system:
- 7kW Simpson & Partner Home Series V3 EV Charger

It took us a total of 1 and a half days to install this system. Will thoroughly enjoyed this project as it was for his own house. 😀
Tariff: Intelligent Octopus G0
- £0.07 per kWh off-peak (11:30pm – 5:30am)
- £0.28 per kWh peak (5:30am-11:30pm)

Using Octopus’ EV tariff this can translate to £0.02-£0.03 per mile
