If it's useful to check out all the detail of how The Electric Car Scheme works, then The Handbook is the place. It's super useful to share with all employees when a scheme is launched at your company. Much of the contents of The Handbook can be found in articles in the Help Center, but it's all here in one tidy link that can be shared.
