Three-Phase Power Installations in Glasgow — Power That Matches What Your Equipment Actually Needs

Three-phase power is what most commercial and industrial equipment actually needs to run properly — machinery, commercial kitchens, workshops, and larger HVAC systems all draw more than a single-phase domestic supply can comfortably handle. We install and upgrade three-phase supplies and distribution boards across Glasgow's commercial and industrial premises.

Three-Phase Power Installations
Behind The Job

Getting the Load Calculation Right Before Any Work Starts

The single biggest mistake we see with three-phase work is sizing the supply or distribution board to what's needed today, with no allowance for what a business will actually run in two or three years. We calculate load based on your current equipment list and reasonable near-term expansion, not just what's plugged in on the day we visit.

Where an upgraded supply from the network operator is required, that process has its own timeline outside our control — we'll be upfront about this early, rather than leaving it as a surprise partway through a project, so it can be factored into your own planning and any equipment delivery dates.

FAQs

Common Questions About Three-Phase Power Installations

Will this affect our current operations during installation?
We plan work to minimise disruption, including scheduling around your operating hours where genuinely possible — we'll discuss this specifically for your site before starting.
What if our DNO application takes a long time?
This is outside our direct control, but we'll keep you updated throughout and can advise on realistic timelines based on similar past applications.
How do I know if I need a three-phase supply?
If you're running heavier machinery, large commercial kitchen equipment, or multiple pieces of power-hungry equipment simultaneously, you likely need three-phase rather than single-phase. We can assess your specific equipment list and confirm.
Do you handle the application to the distribution network operator?
Yes, where a new or upgraded supply is needed from the DNO, we coordinate that process as part of the job rather than leaving you to navigate it separately.
How long does a three-phase installation take?
It depends heavily on whether it's a straightforward distribution board upgrade or a full new supply requiring DNO involvement — we'll give you a realistic timeline once we've assessed the scope.
Can you upgrade an existing three-phase board rather than starting from scratch?
Yes, where the incoming supply has sufficient capacity, upgrading the distribution board itself is often more straightforward than a full new supply.
Do you work on live commercial sites?
Yes, we plan installation and upgrade work to minimise disruption to your operating hours, including phased work and off-hours scheduling where needed.
