18 Circular is a service model within the 18 Degrees company that replaces disposable Cat A lighting with a managed, recoverable, and reusable system. It installs track and high quality luminaires at the base build stage, retains ownership, and reuses products across multiple fit out cycles. This removes most lighting waste, cuts embodied carbon, and gives landlords predictable costs with no capital outlay. The model aligns with ESG commitments, improves programme certainty, and delivers full transparency on maintenance, testing, and end of term recovery. 18 Circular positions lighting as an asset that keeps working for the building rather than becoming waste after each tenant cycle.
