Three-Phase Upgrades · Every UK DNO

Need more power at your property?

If your existing single-phase electricity supply is no longer sufficient, it may be possible to upgrade the connection to three-phase. We manage the DNO application from start to connection offer.

Common reasons

When a three-phase upgrade is the right move.

Three-phase gives you more usable capacity and lets you run higher-power equipment reliably. These are the situations we handle most often.

EV charging

Adding a fast home charger, a workplace bank, or a commercial charging site.

Heat pumps

Air-source or ground-source heat pumps that push the existing supply beyond its comfortable capacity.

Solar + BESS

Larger PV arrays or battery systems where three-phase is the more appropriate connection arrangement.

Commercial equipment

Workshops, machinery, welders, motors, refrigeration, commercial kitchens.

Property extensions & conversions

Extensions, conversions, split units and multi-meter arrangements.

Higher electrical demand

The existing single-phase supply simply isn't enough for what the property is being used for now.

What we manage

Application & connection management, not physical works.

We manage the application and DNO process required to secure the supply upgrade. The physical upgrade itself is delivered by the relevant network operator or an accredited connection provider, depending on the arrangement.
