DO YOU REQUIRE A THREE-PHASE SUPPLY?
Three-phase systems are commonly used in large buildings, such as business offices and industrial sites.
Residential buildings may also employ three-phase power to support the usage of major appliances or equipment requiring substantial electricity such as heat pumps or solar panels.
THE DIFFERENCE BETWEEN SINGLE-PHASE AND THREE-PHASE POWER
Single-phase and three-phase describe two infrastructure systems that distribute electricity to buildings. The main difference between them comes down to capacity and delivery rate.
Three-phase electrical systems can bear higher loads and transmit greater power output than single-phase systems. This makes three-phase equipment well-suited for large facilities with intensive power demands.
Single-phase is the standard supply for most homes as it provides adequate power for smaller domestic loads.
An important difference between three-phase power and single-phase power is the consistency of the delivery of power. Because of the peaks and dips in voltage, a single-phase power supply simply does not offer the same consistency as a three-phase power supply. A three-phase power supply delivers power at a steady, constant rate.
HOW DO I KNOW IF I REQUIRE A 3-PHASE UPGRADE?
If you are uncertain whether your building requires a three-phase electricity supply, consult with a licensed electrician. An expert can thoroughly evaluate all electrical equipment and appliances used in the space and calculate the total power demands.
- Domestic clients typically require an upgrade when installing:
- EV Charger
- Solar Panels
- Energy Storage
- Air Source Heat Pump
PROS AND CONS OF THREE-PHASE SUPPLY
Higher power capacity than single-phase
More efficient than single-phase
More balanced power output than single-phase
Upgrading to a three-phase electricity supply is a more involved process than simply swapping out a fuse.
It typically requires replacing the external wiring that runs from the electrical grid to your building. The existing wires that carry single-phase power may need to be dug up and replaced with three-phase cables. New wire trenching or overhead lines may also be necessary to accommodate the extra connections. Since it affects off-site infrastructure, installing three-phase electricity is a substantial undertaking.
However, Connections2energy will guide you through this process and take on this stress on your behalf.

- Get in touch with Connections2energy to arrange a site visit from a trusted contractor to assess your current single-phase system.
- Our team will obtain quotes for the 3-phase installation and manage the entire upgrade process on your behalf. This includes safely disconnecting the existing supply and installing new 3-phase wiring and equipment.
- After your supply has been upgraded you can then contact your supplier to arrange a meter replacement.
Frequently Asked Questions
How soon can I get my electric upgrade completed?
We aim to deliver your new electric requirements as soon as possible; your project’s timeline is unique as it is dependent on its location, the design selected, and what other projects are taking place in the area.
Your account manager will consider all factors and will be able to indicate a rough estimate for when your works will be completed.
How can I tell if I have three-phase power?
You can tell if your home has three-phase power by looking at the fuse box. Typically, a three-phase system has three 100-amp fuses.
Another way to check is by looking at the wires coming out of the metre. You can also check the phase by inspecting the wires coming from the electric meter - three or four wires indicate a three-phase supply, while two wires signal a single-phase system.
What is an MPAN number and how do I find it?
A Metering Point Administration Number (MPAN) is a unique number for an electric meter. Your MPAN number is normally on your electricity bill. It’s 21 digits long and begins with an ‘S’.
How much will my electric upgrade cost?
The cost of electric work can vary, depending on what is required. Once you’ve spoken to your account manager, they will be able to send over a comprehensive quote and will be able to answer any enquiries you may have.
Do I need to accept your quote?
You have no obligation to accept the quotes we have obtained for your electric requirements. However, your account manager will always do their best to acquire the best prices for your project.
Recently we have witnessed a significant increase in demand for the existing electricity infrastructure network, especially as the construction industry moves away from gas and fossil fuel heating systems.
We would advise our clients that if you have received a formal POC offer, that you accept it before it expires to avoid losing that existing capacity, and the potential of attracting additional reinforcement costs for your supply requirements.
Why can’t an electrician do this work?
An electrician is only qualified to work on the fuse box and your internal house wiring. Electricians are not qualified to work on the electricity supply or electricity meter.
