What moves the price
- Complexity of the job — load balancing across a commercial three-phase system takes more planning than a home upgrade.
- Distance from the power source — a longer cable run from the supply point to the board needs heavier, costlier cable.
- Any necessary upgrades to existing electrical systems — a single-phase board usually has to be replaced with a three-phase board and protection.
- Network operator connection — the network operator's work to upgrade the supply to three-phase adds its own charge to the job.

How to pay less
- Placing the new three-phase board close to the meter keeps the cable run short and the installation cheaper.
- Planning machinery or chargers you will add later lets the electrician size the three-phase board once, avoiding a second upgrade.
- Combining the three-phase upgrade with other electrical work, such as an EV charger, saves paying for separate visits.
- Clearing access to the meter cabinet and the board position before the electrician arrives saves paid time on the three-phase work.
- Checking with the electrician whether a single-phase upgrade would run your equipment can avoid the cost of a full three-phase installation.
Before you book
- Access to the electrical panel and areas where work will be performed.
- Details on current electrical usage and any future power needs.
- Information about existing wiring and any previous electrical upgrades.
- Clear communication regarding appliances or machinery that will be connected.
- Check that the electrician is qualified for three-phase work, and ask how the installation will be earthed and protected.
