Installation of your Ratio EV charger

Ratio Approved Installers

Our network of Ratio approved installers are accredited electricians with thousands of hours of experience installing electric vehicle chargepoints.


Your installer will confirm their arrival time with you in advance of the installation.


Your installer will find the best position for your charger based on your power supply and how you park your car.


The io5 is fixed to the wall, a cable is run from the unit to the mains power supply, and it will be activated for use. The installer will then connect the charger to the Wi-Fi and pair it with the Ratio App.


Your installer will give you a full demonstration of your charger, what the different lights mean and how to get in touch if you have any questions.

Ratio ticked all these boxes and more

At Garage Play we turn tired and run-down garages into a genuine new space for the home, this could be a gym, an office, or simply a neater, nicer garage space. As part of our offering we wanted to supply EV charging equipment, but we need it to be smart enough to cope with differing power availability and solar interoperability, reliable and robust enough to cope with everyday living, plus good looking to fit in with our total proposition. Ratio ticked all these boxes and more!

One happy customer! 

Matt and the team at Ratio helped us out recently when we needed an urgent installation for a solar compatible home installation. They delivered the unit directly to site the next day and Martin even came out to site to make sure everything went well. One happy customer!
