The difference you'll notice once the system is live
Retrofit without major disruption
We work with existing commercial buildings rather than pushing full replacement. That helps you improve control without turning the whole site upside down.
Monitoring that keeps working
We don't stop at installation and walk away. Our remote oversight helps uncover waste and keeps performance in view.
Panels made for this job
Our compact control panels are supplied as part of the retrofit approach. They're built to connect cleanly with the monitoring platform.

Cut wasted energy from the building you already have
Older commercial buildings often burn through energy because plant, controls, and monitoring were never designed to work together properly. We retrofit energy management systems that bring those parts into line, and at Optimum Controls Limited, we handle the work with a practical focus on lower energy use and reduced CO2 emissions. That can make a real difference in places like schools, where heating may run long after classrooms are empty, or in larger public buildings where waste is harder to spot day to day. Our retrofit approach is project based, which suits planned upgrade works without forcing you into a wider replacement programme. We also commission and integrate the equipment properly, so your updated system is not just installed but working efficiently from the start. Once everything is connected, you can see how the building is performing and start making better decisions based on live information rather than guesswork.
A smarter way to manage retrofit performance
Remote visibility changes the game once a control upgrade is in place. Through Optimum Controls Limited, you can view and adjust your system while we proactively monitor performance and flag energy waste that might otherwise keep slipping by unnoticed. Our compact control panels are manufactured and supplied for retrofit projects, and we can also provide them to installers who need dependable hardware that links back to the monitoring platform. That joined-up setup helps you avoid the common problem of new equipment sitting in a building without anyone really using its full capability. If you want support beyond installation, we can continue managing the system through an ongoing monitoring plan.

Frequently asked questions
What does an energy management system retrofit involve?
We add modern control and monitoring capability to an existing commercial building, then commission and integrate the equipment so it works efficiently with your site. That usually means better visibility, tighter control, and a clearer picture of where energy is being wasted.
Can we keep using our existing building systems?
In many cases, yes, because retrofit work is designed to improve what is already in place rather than replace everything outright. The exact scope depends on your current setup and how the controls need to connect with the monitoring platform.
Is remote monitoring included after installation?
Remote monitoring can be included as part of the retrofit setup, and we can also provide an ongoing plan once the project is complete. That gives you continued access to system adjustments, performance oversight, and assist in spotting avoidable energy use.
