We work with developers at the earliest stage to design solar systems that meet compliance, reduce cost, and integrate seamlessly into the build programme — avoiding delays and redesign later.
Learn more →Systems tailored to each plot type while standardising where it matters — reducing cost, simplifying installation and ensuring consistency across the entire development.
Learn more →Full solar delivery across every plot — coordinated with your build programme to ensure on-time installation, seamless integration and fully compliant handovers.
Learn more →Systems shouldn't stop performing at handover. We offer ongoing O&M packages — scheduled servicing, performance monitoring and fault response — for single homes or whole developments.
Why Circle
Every system handed over with live monitoring — generation, storage and export, visible in real time.
