Onto - Electric Car Subscription

Add InstaVolt as a charging bolt-on

An Onto subscription includes free access to over 11,000 electric charge points as part of the Shell Recharge network, and the InstaVolt network is available as an optional £120 bolt-on. 

InstaVolt is one of the largest public rapid networks in the UK, with over 900 rapid charging stations, and more sites added weekly!

How to add the InstaVolt charging bolt-on?  

There are two ways to add the InstaVolt bolt-on to your subscription:

  • Firstly, when booking your car you will have the option to add the InstaVolt bolt-on during the checkout process.
  • Secondly, it can be added at any point through the ‘Bolt-on’ section of ‘My Account’.


Please note, the InstaVolt bolt-on will be visible in My Account web and in your User Hire Agreement after your next renewal, but will not initially be visible in the mobile app - we're working on it, it will be available soon.

How does it work?  

Each car is supplied with an InstaVolt card which has instructions for how to be added if not purchased during the booking process. If added during the booking process, the card will be activated for use within 24 hours of your car arriving. If adding the bolt-on afterwards, a member of our customer support team will activate it for you, which will take up to 2 working days.

What happens if your card is lost, stolen or damaged?  

If your InstaVolt charging card is lost or stolen, you must notify us as soon as possible, so that we can cancel it. If you require a replacement card (for example, because your card is lost, stolen or damaged), let us know and we will order a replacement card for you from the card provider. You will be responsible for the cost of the replacement card.

What happens if your card faulty?  

If your InstaVolt charging card is faulty, you must first contact the charging provider (InstaVolt helpline: 0808 281 4444), and give them the details of your card and the charging unit you attempted charging at. If they can not resolve the issue, contact us and we will order a replacement card.
