Your energy supplier

The company that sends your bills. They're responsible for your meter – including smart meters – and your account. Call them about billing, meter readings, faulty or old meters and prepayment issues.

Your network operator

The distribution network operator (DNO) owns the cables, substations and the supply into your home, up to and including the cut-out and main fuse next to your meter. Call them – via 105 in England, Scotland and Wales – about power cuts, damaged supply cables, the main fuse, new connections and supply upgrades.

Electricians also notify them about EV chargers and some other new loads.

Your electrician

Everything after the meter – the consumer unit, wiring, sockets, switches, lights and fixed equipment – is yours, and that's where an electrician comes in. Faults, rewires, new circuits, testing and EV charger installation are all electrician jobs.

Common questions

Can an electrician move my meter?

Not by themselves. Meter moves involve your supplier and sometimes the network operator, though an electrician can prepare the new position.

Who replaces the main fuse?

The network operator. Never tamper with the sealed cut-out.

Who upgrades my supply for an EV charger?

The network operator, usually arranged through your installer.
