Three-phase power is essential for running industrial machinery, large motors, commercial kitchen equipment and high-capacity workshop tools. Our three-phase power installation service delivers balanced, efficient three-phase supplies from the DNO point of connection right through to your distribution boards and equipment.

How It Works

Our Process

01

Supply Assessment

We assess your current single-phase supply and consult with the DNO to confirm three-phase availability and connection requirements.

02

Load Calculation & Design

We calculate your total three-phase load, design the distribution network and specify cables, breakers and isolators for balanced, safe operation.

03

Installation

Our electricians install the three-phase supply, distribution boards, sub-mains and equipment circuits with full safety isolation procedures.

04

Testing & Commissioning

We test insulation, continuity, phase rotation and load balance. Every circuit is certified before the system is commissioned for use.

FAQ

Common Questions

Can any property get three-phase power?

Most commercial and industrial properties can, but it depends on DNO infrastructure in your area. We consult the DNO and handle the application process for you.

How much does a three-phase supply cost?

DNO connection costs vary widely from £1,000 to £10,000+ depending on distance from the nearest three-phase point. We provide a full cost breakdown after DNO assessment.

Do I need three-phase for a home workshop?

It depends on your equipment. Most home workshops can run on single-phase with a rotary converter for occasional three-phase tools. We advise the most cost-effective solution.
