Three-phase supply upgrade

With three phases you spread the load across three wires instead of one. Needed for power tools, a fast charger or a heat pump. We prepare the fuse box and handle the application with the grid operator.

Three-phase supply upgrade: how we work

What three phases give you

On a single phase all the current has to go through the same wire, limited by the main fuse. With three phases you spread the load, so cooking, charging and heating do not get in each other's way. A car also charges faster.

Calculate first

Not everyone who thinks they need three phases actually does. We add up what really runs at the same time. Sometimes smart switching or load balancing is enough and you save the cost of an upgrade.

Who does what

The grid operator upgrades the supply itself; we prepare the fuse box, fit the right board and file the application on your behalf. You do not have to chase it.

After the upgrade

We spread the circuits across the three phases so the load is even. An uneven split leads to one phase tripping while the other two do nothing.

Frequently asked questions about three-phase supply upgrade

Question not answered here? Call or message us and we will think it through with you, free of charge.

How do I know whether I already have three phases?

In the meter cupboard you would see three main fuses side by side instead of one. A photo tells us immediately.

What does an upgrade cost?

The grid operator sets that tariff. We can tell you what our part costs and how the process runs.

How long does the application take?

Reckon on several weeks to months, depending on how busy the grid operator is. We make sure the fuse box is ready when they arrive.

Is three-phase needed for a charging point?

Not always. With load balancing a charger works fine on one phase, it just charges more slowly. We calculate whether upgrading pays off in your case.
