If the loads in my house are an issue or I can't get a fuse upgrade, can I still have an EV charger?

Using the Home Energy Manager to allow your S&P chargepoint to work safely and effectively without upgrading your main fuse.

Yes, you can. With an S&P charger you can include the Home Energy Manager within your purchase, this will allow the installer to set a limit that will not be exceeded and therefore will protect your supply fuse by load balancing the energy supply between your home and your chargepoint.
