Single-phase installations, repairs and upgrades for shops, offices and smaller commercial units — correctly designed, protected and certified.
Single vs. three-phase: choosing what you need
Most small commercial (shops, offices, small restaurants) use single-phase — adequate for lighting, computers, small kitchens. But adding machinery, large kilns, commercial refrigeration, or EV chargers can overload single-phase. Three-phase power lets you run larger loads more efficiently. We assess your needs and advise: can you upgrade single-phase capacity, or is three-phase the answer?
The upgrade path
Upgrading single-phase capacity: contact your DNO, they assess if they can supply more. If not, three-phase is the next step. Switching to three-phase: requires DNO approval, new supply cable, new board. Takes 2–8 weeks depending on infrastructure.
How it is priced, and what you get back
A supply upgrade has two separate parts: the DNO's charge for the work on their side of the meter, which they quote directly and which varies enormously with what is already in the street, and our installation on your side. Moving from single to three-phase is the larger of the two moves. We handle the DNO application and liaison for you so it isn't your problem to chase. Where the upgrade is what lets the business actually run its equipment, the return on it is immediate.
