Our Solutions

Solar

C8 Eco designs and installs solar PV systems tailored to the energy demands of commercial buildings.

Whether integrated into new construction or retrofitted to existing sites, our systems provide clean, scalable electricity that reduces reliance on the grid and improves your building’s energy profile. We guide clients through every step of the process – from feasibility studies and system design to installation and ongoing performance monitoring – ensuring maximum cost savings and supporting decarbonisation targets.

Our solutions allow businesses to harness renewable energy and lower operating costs while achieving long-term sustainability goals. We ensure that each system is optimised to deliver lasting value and contribute to a cleaner, greener energy future.

Energy Monitoring

C8 Eco delivers advanced energy monitoring solutions that provide businesses with valuable insights into their energy usage.

By installing smart metering and analytics systems, we enable real-time visibility into consumption patterns, helping identify inefficiencies and inform data-driven decisions. Monitoring is also essential for avoiding costly penalties associated with maximum demand charges, ensuring energy use is optimised and costs are controlled.

Our systems empower businesses to take control of their energy consumption, improve performance, and support sustainability goals. With accurate data at your fingertips, you can make smarter decisions and reduce energy waste across your operations.

Heat Pumps

C8 Eco designs and installs high-efficiency heat pump systems to provide low-carbon heating and cooling for commercial spaces.

Heat pumps are among the most energy-efficient and environmentally-friendly solutions available, offering substantial reductions in emissions compared to fossil fuel-based systems. From air-source to complex integrated heat pump systems, we ensure the right configuration to meet the specific needs of each building.

Our expertly designed systems deliver reliable performance and energy savings, helping businesses reduce carbon emissions and operating costs. We ensure that every installation is optimised for maximum efficiency and long-term benefits.

Battery Storage

C8 Eco integrates commercial battery storage solutions to give businesses more control over their energy use.

Our systems enable greater self-consumption of renewable energy, reduce peak demand, and protect against grid outages. By incorporating battery storage into your building’s energy strategy, we help unlock the full potential of on-site renewable generation while lowering energy costs and boosting resilience.

Battery storage provides businesses with flexibility, enabling them to manage energy consumption efficiently and reduce reliance on the grid. Our tailored solutions help increase operational resilience and maximise the value of renewable energy investments.

Building Energy Management Systems (BEMS)

C8 Eco provides advanced Building Energy Management Systems (BEMS) that optimise energy consumption within commercial buildings.

These sophisticated platforms monitor, control, and analyse energy use in real time, identifying inefficiencies and opportunities for improvement. BEMS can automate actions like adjusting heating or lighting based on occupancy or time of day, driving both energy savings and operational efficiency.

Our solutions provide businesses with the data and insights needed to optimise energy use, reduce waste, and manage costs effectively. We deliver systems that are scalable and adaptable to the specific needs of your building.
