Grid connection

Connecting power for low- or high-voltage systems and substation works with clear communication and disciplined project management to ensure your site is energised safely without delays or unexpected costs.

Connecting your site to the grid is one of the most important steps in any project. We provide a complete grid connection service, covering low-voltage, high-voltage, and substation works, supported by in‑house civil engineering experts.

We manage the process from end to end, coordinating with network operators and delivering connections that are safe, compliant, and ready for use.

Our engineers design and install connections that match the capacity and operational needs of your site, whether it’s a residential estate, a logistics hub, or a large electric vehicle charging depot. We handle the technical detail and the practical delivery, so you get a connection that works from day one.

We know how critical timelines and budgets are. That’s why we combine technical expertise with disciplined project management, keeping communication clear and progress visible. With us, you have one partner responsible for every element of the grid connection, giving you confidence that your infrastructure will be energised on time and built to last.

Key benefits of grid connection services

Reliable

Connections built to perform consistently from day one.

Safe and compliant

Works delivered to the highest compliance standards.

Efficient

Projects managed to keep cost and timelines under control.

Low voltage

We design and install low-voltage connections for smaller sites and developments, providing safe and efficient links to the grid. Our team manages cabling, switchgear and testing to deliver connections that are ready for immediate use.

High voltage

For larger projects, we deliver high-voltage connections that meet complex capacity requirements. Our engineers handle design, installation, and energisation, coordinating with network operators to bring power safely to your site.

Substation design and install

We provide an end-to-end solution for substations from design and civil engineering works through to installation and commissioning. Each substation is built to specification, compliant with regulations, and tested thoroughly before handover.

Civil engineering

Our civil engineering team supports every grid connection with trenching, ducting, foundations, and reinstatement. By integrating civil engineering with electrical works, we keep projects moving smoothly and avoid delays.

“As Zest look to expand our network of charge points across the UK, Utility Line have been an important part of some of our biggest projects to date. From design and obtaining connections through to project delivery, they have provided excellent service, and we look forward to working with them in future.”
