Bespoke Contracts
When a site goes live, our job isn’t done — in fact, that’s where our COMA (Connection Operation and Maintenance Agreement) really kicks in.
Think of it as long-term backup for your electrical infrastructure. From regular maintenance and compliance checks to callouts and fault response, we’re here to keep your asset running smoothly and safely for the long haul.
Every COMA agreement is tailored to the needs of your site, with a dedicated team who know the details inside out. You’ll get fast response times and clear communication, giving you confidence that your infrastructure is in the best hands.

Unplanned Outage? We've got you covered.
In the event of an unplanned outage, our teams are on hand 24 hours a day, every day of the year.
A rapid response from our in-house experts will get you back up and running safely, reducing downtime and inconvenience.
As part of our regular planned maintenance, we will provide recommendations for upgrades or replacements as required, to keep your system safe and efficient. Whether that is a small remedial, or a full transformer removal and replacement - we will provide a sustainable and cost-effective solution to suit your needs.
