Full Switchgear & Transformer Commissioning
Complete Commissioning Services for HV and LV Equipment
We provide full commissioning for switchgear and transformers across high and low voltage systems in the UK. Our team ensures every component is correctly installed, fully tested and ready for safe energisation.
Why Proper Commissioning Matters
Commissioning is a critical step in any electrical installation. It confirms the system operates as intended and meets all safety, design and performance standards. We help protect your assets, reduce risk and ensure long-term reliability from day one.
Our Commissioning Services
We work on new installations, upgrades and network extensions. Each service is tailored to your project and includes a structured sequence of checks, tests and documentation.
Our commissioning process includes:

Frequently Asked Questions
What is included in full commissioning?
We carry out detailed testing and configuration of switchgear, transformers, relays and supporting systems to ensure everything is safe and ready for service.
Do you commission both HV and LV systems?
Yes. Our team works on both high voltage and low voltage systems and can support mixed-voltage installations with full documentation.
Can you support during energisation?
Yes. We assist with the energisation process, ensuring all systems are stable and fully tested before going live.
Do you provide commissioning reports?
Every project includes a full commissioning report with test results, settings, observations and sign-off for audit and compliance purposes.
