Yes, most UK properties run off a power supply (called single-phase) which easily supports 7kW chargers.
To benefit from 7kW charging the first thing to check is the size of your property’s main fuse.
It is preferable to have a 100A incoming supply fuse into the property to allow the maximum output of a 7kW charger, however, the electrical demand of the property needs to be calculated and confirmed to make sure this is suitable.
If you have less than a 100A main fuse then we are still able to install a charger, however, depending on what the demand on the property is, you may need to have the fuse upgraded by the local DNO (power Distribution Network Operator)
You can find your main fuse linked to your electricity supply meter. There should be a label on the side of the fuse showing the amp rating. If you are unable to find it, please call your electricity provider to clarify your fuse rating.
