Should I make users pay for usage of the charging points or should they be free to use. Can you advise?
The decision is ultimately one of your policy. You can decide to either charge for the usage of charging points, or leave the usage free to authorised customers. You might also wish to charge different user groups different rates for charging. e.g. a hotel might want to charge overnight guests a different rate than guest that just pop into the hotel bar for a meeting.
It largely depends on whether you are prepared to meet the cost of the electricity used by the charging points and for the installation. Either way we will advise you on the best solution that meets your needs.
