Do you actually need three-phase?

Not always. We check what you want to run and your current supply first. Sometimes a dedicated single-phase circuit does the job for less.

How the upgrade works

We look after the switchboard and wiring inside your property and help with the application to the network. Any work on the supply connection itself is done by an accredited service provider, and we coordinate it with you.

Common questions

How long does a three-phase upgrade take?

The wiring is usually quick. Most of the time is waiting on the network approval and connection, which we help you through.

Can I get three-phase to my shed?

Yes. We can run a sub-main to a shed or workshop and fit a board and outlets there.

Will three-phase help my EV charger?

It allows faster charging with a three-phase charger, if your car supports it. We'll check before you spend money on it.
