Three-phase power upgrades - for commercial, industrial & EV applications
Single-phase supply not enough for your commercial premises or EV charging infrastructure? We manage the full upgrade to three-phase, application, NERS-accredited installation and energisation.
how it works
Who needs an electric upgrade?
EV charging hubs
Multiple EV chargers require a three-phase supply to operate at full capacity.
Commercial kitchens & hospitality
High-demand catering equipment outgrowing single-phase supply.
Manufacturing & industrial
Heavy machinery and production equipment requiring higher power capacity.
Data centres & tech facilities
High-density computing and cooling systems require significant power.
how it works
What is the difference between single-phase and three-phase?
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.

Why NERS accreditation matters
The National Electricity Registration Scheme is administered on behalf of UK Distribution Network Operators (DNOs). It is the mandatory accreditation for any contractor carrying out new connections, alterations or diversions on the electricity network.
As a utility facilitator, we don’t carry out the physical works ourselves, but every contractor we appoint must hold current NERS accreditation. To ensure fair competition, DNOs allow you to use NERS-accredited Independent Connection Providers (ICPs) and Independent Distribution Network Operators (IDNOs) rather than going directly to the DNO itself.
This is where we add significant value. We access the market, obtain competitive quotes from accredited ICPs and IDNOs, and appoint the best combination of price, quality and programme fit for your specific project.

common questions
Electric connections, your questions answered
”What
How much does a three-phase upgrade cost?
The cost of a three-phase upgrade depends on several factors: the distance from the nearest suitable network connection point, whether network reinforcement is required by the DNO, the complexity of the on-site installation and the specific DNO area your premises sit within.
Rather than going directly to your DNO, which will typically give you one price at their standard rate, Connections2energy accesses the open market, obtaining competitive quotes from NERS-accredited Independent Connection Providers (ICPs) and Independent Distribution Network Operators (IDNOs). This competitive process frequently delivers significant cost savings compared to the DNO's own quotation, sometimes running into thousands of pounds on larger projects.
We provide a full, itemised quotation at no obligation. Contact our team with your project details, and we'll give you a clear picture of what to expect.
How long does a three-phase upgrade take?
Timescales vary depending on the DNO area, the complexity of the upgrade and whether any network reinforcement is required before the new supply can be provided. As a general guide, straightforward three-phase upgrades can be completed within 8 to 16 weeks from application. Where network reinforcement is needed, which occurs when the local network doesn't have sufficient capacity to provide the increased supply without infrastructure improvements, timescales can extend beyond this.
The single most important thing you can do to protect your programme is to engage us early. Many clients come to us after they've already started fit-out works, only to discover the three-phase upgrade will take longer than anticipated. Getting the DNO application submitted at the earliest possible stage, ideally before construction begins, gives you the maximum possible lead time and avoids the upgrade becoming a critical path item on your project.
Can you manage electric upgrades alongside other utilities?
Yes, and we'd recommend it. Managing electric alongside gas, water and telecoms through our multi-utility service reduces your delay risk from 44% to just 11% (NFB data). One account manager, one programme, one point of contact for all utilities.
