A polyphase electrical system 2 that supplies a property includes a control apparatus 4. The system 2 comprises a plurality of live wires 8 and includes a plurality of controllable loads 12, 13, 14, 16. The vector sum of the current over the plurality of live wires 8 defines a phase imbalance. The plurality of controllable loads 12, 13, 14, 16 comprises a first load 12, powered by a first set of live wires, and a second load 14, 18 powered by a different second set of live wires. The control apparatus 4 is configured to receive a measurement of current through a live wire or a neutral wire, and to control a selectable one, or both, of the first load 12 and the second load 14, 18 in response to the measured current to vary a current drawn by at least one of the first and second loads and reduce the phase imbalance. The load 16 may be an EV charger.
